Growth in Larval and Metamorphosed Eurypharynx Pelecanoides Vaillant, 1882 (Pisces, Anguilliformes, Eurypharyngidae) from the mid North Atlantic
Authors: van Utrecht W.L.
Published: May 2019

The difference between the larvae of Eurypharynx pelecanoides and Saccopharynx ampullaceus, both belonging to the suborder Saccopharyngoidei (formerly Lyomeri), does not consist only of different numbers in myomeres but also of the structure of the suspensorium of the lower jaw. In E. pelecanoides it consists of two separate bones, the hyomandibulare and the quadratum. According to Orton (1963) in S. ampullaceus the suspensorium consists of only one piece of bone.

Six species of the genus Gnathia (Crustacea: Isopoda: Gnathiidea) are recorded from the Caribbean Sea of northern Colombia. Gnathia gonzalezi n. sp., Gnathia magdalenensis n. sp., Gnathia samariensis n. sp., and Gnathia vellosa n. sp. are described; Gnathia beethoveni Paul & Menzies, 1971 and Gnathia virginalis Monod, 1926 are redescribed and recorded for the first time from Colombia. The Gnathiidea of the Caribbean Sea and Gulf of Mexico are reviewed.
The Genital Fields of Canuella Perplexa and C. Furcigera (Copepoda, Harpacticoida) - Comparative Morphology and Functional Aspects
Authors: Glatzel Thomas
Published: May 2019

The harpacticoids Canuella perplexa T. & A. Scott, 1893 and Canuella furcigera Sars, 1903 differ not only in size and length of the furca, but above all in the structure of the genital fields in both sexes. These differences, which have not been described exactly so far, are demonstrated by SEM micrographs and by drawings. Since there is no adequate terminology for the description of genital fields, terms are introduced in this study. A partly extruded spermatophore in a male specimen of Canuella perplexa is shown by a SEM micrograph. Mating has never been observed in either species; however, from the anatomical structure some conclusions may be drawn on the possible configuration of the genital fields during mating.
Zwei Neue Metacyclops (Crustacea Copepoda) von den Westindischen Inseln Barbados und Aruba: M. Agnitus n. sp. und M. Mutatus n. sp., sowie ein Bestimmungsschlüssel für das Genus
Authors: Herbst Hans-Volkmar
Published: May 2019

Aus Brunnen der Inseln Barbados und Aruba (Westindische Inseln) wurden zwei neue Metacyclops-Arten beobachtet. Eine davon gehört in die minutus-Gruppe und wird aufgrund spezifischer Merkmale, die sie von Metacyclops minutus (Claus, 1863) unterscheiden, als Metacyclops agnitus n. sp. beschrieben. Da Beschreibungen von M. minutus mit umfassenden Maßangaben fehlen, werden diese für eine westdeutsche Population (Raum Bonn) geliefert. Die zweite neue Art dürfte von mendocinus-ähnlichen Vorfahren abstammen. Gegenüber den morphologisch Vergleichbaren M. aequatorialis Dussart, 1977 und M. chelazzi Dumont, 1981 läßt sich die als Metacyclops mutatus n. sp. bezeichnete neue Art eindeutig abgrenzen. Als Hilfsmittel für künftige Untersuchungen ist überwiegend aufgrund von Literaturangaben ein Bestimmungsschlüssel für die Gattung Metacyclops aufgestellt worden.

Sédentarité, déplacements et répartition des individus dans une population de Lacerta viridis (Laurenti, 1768) (Lacertilia, Lacertidae)
Authors: Saint Girons H. , Bradshaw S.D.
Published: May 2019

Dans une population française de Lacerta viridis occupant, le long d’un canal, une surface de 260 × 11 à 25 m, 76 adultes et subadultes ont été marqués au cours de séries de captures-recaptures à intervalle d’une semaine, en août 1983, mai 1987, septembre 1987 et mai 1988. 21 recaptures faites après quatre mois à cinq ans montrent que les Lézards sont très sédentaires et se cantonnent dans un espace vital de 200 à 600 m2 environ, les déplacements par rapport à la capture initiale variant de 0 à 36 m et ne se modifiant pas avec le temps. Toutefois, quatre individus sur les 14 repris après plus de huit mois avaient nettement changé d’espace vital, la distance parcourue étant comprise entre 42 et 143 m. Les observations directes et les recaptures à court terme suggèrent que les différentes parties de cet espace vital sont exploitées successivement, chaque individu restant pendant plusieurs jours ou quelques semaines dans une zone restreinte ne dépassant pas 10 à 15 m de long, puis la quittant pour y revenir ensuite. En mai, la densité des adultes et des subadultes de 21 mois est voisine de 194 individus à l’ha, les mâles et les femelles étant en nombre égal. Les espace vitaux et même les petits domaines provisoires se recoupent très largement, surtout dans les emplacements les plus favorables. On doit donc admettre que l’intolérance intra-spécifique, forte entre les mâles adultes, faible mais notable dans tous les autres cas, n’empêche pas une densité élevée dans un milieu à végétation assez dense.

Dicrotrichura tricincta gen. et spec. nov.: A new tantulocaridan (Crustacea: Maxillopoda) from the Mediterranean deep waters off Corsica
Authors: Huys Rony
Published: May 2019

The new genus and species, Dicrotrichura tricincta, is described from deep mud (1220 m) in the Ligurian Sea (western Mediterranean). It is the first tantulocaridan not found to be attached to a crustacean host but free living in the sediment. It is assigned to the Deoterthridae on the basis of the absence of a rostrum, the abdominal segmentation and the characteristic cephalic pore pattern. It can be distinguished from all known tantulocaridans in the presence of peculiar, bi-articulated caudal setae and the difference in thoracopodal setation between leg 2 and legs 3–5. Some new structures located on the attachment disc are described for the first time. D. tricincta is the second tantulocaridan to be recorded from the Mediterranean.
Gammaridea and Caprellidea (Crustacea — Amphipoda) of the Portuguese south-western continental shelf: taxonomy and distributional ecology
Authors: Marques João Carlos , Bellan-Santini Denise
Published: May 2019

Amphipods from the Portuguese south and south-western continental shelf were studied with regard to the species inventory, distribution, and ecology. This study allowed the identification of 113 species, belonging to 52 genera; of these species 28 are recorded for the first time along the Portuguese coast. Two species, Ampelisca heterodactyla Schellenberg, 1925, and A. latifrons Schellenberg, 1925, are redescribed. The latter is different from the Ampelisca named latifrons by Ledoyer in 1972 and 1982.

Published: May 2019

During the Amsterdam Expedition to the Dominican Republic a new Stygiomysis species, S. aemete, was captured in a well about 5 km east of the Haitian border in the Pedernales Province. Its relation to the other Caribbean Stygiomysis species as well as the biogeography of the genus is discussed.
Seasonal variation in copepod abundance in relation to other zooplanktonic groups in the northwestern Mediterranean
Authors: Kouwenberg Juliana H.M.
Published: May 2019

Abundance of adult copepods and late copepodid stages from the upper 50 m in the Golfe du Lion (N.W. Mediterranean) was studied by the author in 1986, 1987, and 1988 for each season. Altogether 87 stations at 22 fixed locations were sampled in the frame of the multidisciplinary French/Spanish programme Pélagolion/Leopel in the near-coastal region (≤ 25 m bottom depth), the Rhone dilution zone, the neritic region (≤ 200 m bottom depth), and the oceanic region (200–2000 m bottom depth). Abundance of other zooplanktonic groups was estimated and total zooplankton biomass was determined for the upper 50 m. Copepod abundance was highest during September 1986 (all regions) and July 1987 (neritic). Total biomass was highest during July 1987 and May/June 1988, caused by high abundance of many other zooplankters.
Burrimysis palmeri, a new genus and species of Heteromysini (Crustacea: Mysidacea) from an anchihaline cave lake of Cabrera (Balearic Islands, Mediterranean)
Authors: Jaume Damià , Garcí Lluc
Published: May 2019

Burrimysis palmeri, a new genus and species of Heteromysini, is described from the deep layers of an anchihaline cave lake on Cabrera (Balearic Islands). It shares with Mysidetes Holt & Tattersall and Deltamysis Bowman & Orsi a third thoracic limb endopodite without enlarged segments, and rudimentary pleopods in adults of both sexes. Nevertheless, Burrimysis differs, among other characters, in the armature and profile of telson and uropods. Its affinities and biogeographic significance remain uncertain.
Copepoda (Crustacea) associated with commercial and non-commercial Bivalvia in the East Scheldt, The Netherlands
Authors: Stock Jan H.
Published: May 2019

Six species of Copepoda Poecilostomatoida of the families Myicolidae, Sabelliphilidae, Lichomolgidae, and Mytilicolidae are recorded from six different species of intertidal bivalves in the East Scheldt (The Netherlands), a branch of the southern bight of the North Sea. One bivalve species may harbour more than one species of copepod, and one copepod species may use more than one species of bivalves as host.
The taxonomic significance of the short-shafted mesotriaene reviewed by parsimony analysis: validation of Pachastrella ovisternata Von Lendenfeld (Demospongiae: Astrophorida)
Authors: Maldonado Manuel
Published: May 2019

The spicule complement of a demosponge specimen collected from the Atlantic coast of Spain was noted to be similar to that of Pachastrella monilifera, but particularly characterized by the presence of short-shafted mesotriaenes. After detailed examination, it was concluded that the specimen undoubtedly belonged to the species Pachastrella ovisternata Von Lendenfeld, 1894. For a long time, this species has been regarded a synonym of Pachastrella monilifera Schmidt, 1868. Examination of this new specimen showed that Pachastrella ovisternata was a valid species of the genus Pachastrella. Moreover, it denoted the real existence of mesotriaenes in this genus.
New records and redescriptions of American species of Mesocyclops and of Diacyclops bernardi (Petkovski, 1986) (Copepoda: Cyclopoida)
Authors: Reid Janet W.
Published: May 2019

Recent collections in the south central U.S.A. have included three neotropical and one probably introduced species that are presently assigned to the cyclopoid copepod genus Mesocyclops. Mesocyclops longisetus var. curvatus Dussart, 1987, is reported from Louisiana, U.S.A., and Panama; published records of Mesocyclops longisetus (Thiébaud, 1914) sensu lato in the southern U.S.A. are reviewed. Mesocyclops reidae Petkovski, 1986, is reported from Mississippi, U.S.A., and Honduras. Mesocyclops ruttneri Kiefer, 1981, is redescribed from type specimens collected in Austria, and newly reported from Louisiana, Mississippi, China, Thailand, and Viet Nam. This species is considered to have been introduced from Asia into Austria and the U.S.A. Mesocyclops bernardi Petkovski, 1986, newlyrecorded from Louisiana and Mexico, is transferred to the genus Diacyclops.

According to our standard of the appendicular chaetotaxy, the following species are redescribed: Allacma fusca (Linné, 1758), Allacma gallica (Carl, 1899), Spatulosminthurus lesnei (Carl, 1899), and Spatulosminthurus betschi Nayrolles, 1990.
New species of Zyzzya, Cornulella, Damiria, and Acheliderma (Porifera: Poecilosclerida), with a review of fistular genera of Iophonidae
Authors: van Soest R.W.M. , Zea S. , Kielman M.
Published: May 2019

New sponge species belonging to the closely related fistular genera Zyzzya, Cornulella, Damiria, and Acheliderma are described from reef habitats off the coasts of Colombia, Bonaire and Curaçao in the southern Caribbean. With very few exceptions these sponges are small to tiny specimens inhabiting crevices and other cryptic habitats; some may be excavating. For comparison both published and unpublished material belonging to these genera from other parts of the world was examined, and this yielded several nomenclatorial changes and a further three new species from the Indian Ocean. The new species are: Zyzzya invemar (Caribbean), Cornulella santamartae (Caribbean), C. tyro (Seychelles), C. amirantensis (Seychelles), Damiria leonorae (Caribbean), D. toxifera (Seychelles) and Acheliderma lisannae (Caribbean). All species belonging to these genera, as well as to the closely related Indo-Pacific genus Paracornulum, are briefly diagnosed. The genera and species of this group are found to be distributed over tropical and subtropical waters of all three oceans. The five genera were so far of controversial systematic allocation, although their close relationship with Cornulum was generally accepted. The recently revived family Iophonidae is demonstrated to be the likely assemblage for them. A brief survey of Iophonidae genera is presented and a preliminary phylogenetic analysis of the fistular genera is attempted. Although several parts of the phylogenetic relationships remain unsolved, it is nevertheless clear that in all genera the closest relatives are not found in adjacent areas, but are often disjunct.
Systematic value of the ultrastructure of the sucker surface in the squid family Mastigoteuthidae (Mollusca: Cephalopoda)
Authors: Salcedo-Vargas Mario Alejandro
Published: May 2019

The ultrastructure of the sucker surface is described and its systematic value for mastigoteuthid squids, which bear minute suckers, is considered. An introduction to sucker terms is given and a redefinition of these terms is attempted. Using scanning electron microscopic data, two genera and four subgenera of Mastigoteuthidae from the Northwest Pacific are distinguished. The presence of “cushions” in the sucker is discussed and considered as a character important for understanding adaptations of cephalopods to the deep-sea.
New perspectives on the evolution of the genus Typhlatya (Crustacea, Decapoda): first record of a cavernicolous atyid in the Iberian Peninsula, Typhlatya miravetensis n. sp.
Authors: Sanz Sebastián , Platvoet Dirk
Published: May 2019

On several occasions, shrimps belonging to a new species of the genus Typhlatya were collected in a cave in the province of Castellón, Spain. This is the first record of the genus in the Iberian Peninsula. The species is described and the validity, distribution, and zoogeography of the genus, as well as the status of the genus Spelaeocaris, are discussed. Former models for the evolution of the genus Typhlatya and its genus group are reviewed, as well as the system of inner classification of the Atyidae and its biogeographical meaning. For the age and evolution of the genus we developed a new model based on vicariance principles that involves further evolution of each species after the disruption of the ancestral range. This allows new estimations for the age of the genus. Accordingly, we suppose that other proposals, such as recent dispersal through the sea, should be disregarded for this genus. The evolutionary development of this species is discussed in the context of the geological history of the area and the world distribution of the genus, the genus group, and the family.
Chromosomal basis for a bilateral gynandromorph in Pycnogaster inermis (Rambur, 1838) (Orthoptera, Tettigoniidae)
Authors: Barranco P. , Cabrero J. , Camacho J.P.M. , Pascual F.
Published: May 2019

Morphological and cytogenetic analyses of a spontaneous gynandromorph of Pycnogaster inermis, found in a natural population in the Spanish Sierra Nevada, have shown that the left side was male and the right side female, with almost perfect bilateral symmetry. Ventral valves of the ovipositor were very short, appearing as two spurs; dorsal valves were longer but still shorter than normal. The specimen had an apparently normal testis on the left side and a well-developed ovary on the right side.
On the occurrence and distribution of Presbytis comata (Desmarest, 1822) (Mammalia: Primates: Cercopithecidae) in Java, Indonesia
Authors: Nijman Vincent
Published: May 2019

The colobine monkey Presbytis comata is confined to the rain forests of West and Central Java, Indonesia. In order to determine its distribution, a review of the literature, evidence from the study of museum specimens, and the results of recent surveys are presented. Recent surveys in the central parts of the island indicate that P. comata is still present on four volcanic mountain complexes, viz. Mt. Sawal, Mt. Slamet, Mts. Dieng, and Mt. Lawu. The present paper gives the results of the surveys combined with a review of its distribution. Altitudinal and habitat preferences, and the conservation status of the species are discussed.

The New World species of Craspedochaeta Czerny, 1903 are revised and the first New World representative of the C. biseta group (C. argoniae spec. nov.) is described from Ecuador and Bolivia. Ten new species (C. amazonensis spec. nov., C. apsilutea spec. nov., C. candida spec. nov., C. chela spec. nov., C. feminea spec. nov., C. melanosoma spec. nov., C. pacaraima spec. nov., C. pollostos spec. nov., C. protomis spec. nov., C. weemsi spec. nov.) are described from the C. transversa species group and eight new species (C. biloba spec. nov., C. brunneivibrissa spec. nov., C. chauliodon spec. nov., C. loreto spec. nov., C. phaios spec. nov., C. pullipleura spec. nov., C. xanthonotum spec. nov., C. zongo spec. nov.) are described from the C. concinna species group. Craspedochaeta basalis brasiliensis Sóos, 1961 syn. nov. and C. piceoflava (Sóos, 1962) syn. nov. are synonymized with Craspedochaeta annulipes (Johnson, 1913) comb. nov.; C. minuta Sóos, 1962 syn. nov., C.atra (Kertesz, 1903) syn. nov. and C. albohalteria Sóos, 1962 syn. nov., are synonymized with C. concinna (Williston, 1896). Craspedochaeta sasakawai nomen nov. is provided as a replacement name for C. pleuralis (Curran, 1936), which is a junior homonym of C. pleuralis (Williston, 1896) comb. nov. Agonistic behaviour is recorded for the first time in Craspedochaeta, with photographs showing male-male interactions in the Bolivian species C. pullipleura. A key is provided for all 31 New World Craspedochaeta species and the relationships of the C. concinna and C. transversa groups are discussed on the basis of male and female morphological characters. Species of Craspedochaeta are recorded for the first time in North America, with C. weemsi found in Florida, C. concinna found in Florida and New Mexico, and C. annulipes found in Georgia, Maryland, Mississippi, North Carolina, and Texas.
The first larval description in the genus Diaphorocera Heyden (Coleoptera: Meloidae: Cerocomini): D. chrysoprasis Fairmaire
Authors: TURCO FEDERICA , GIULIO ANDREA DI , BOLOGNA MARCO A.
Published: May 2019

The first instar larva of Diaphorocera chrysoprasis Fairmaire, 1863, a Western Saharan species, is described and figured for the first time. Adults of D. chrysoprasis were collected in Tunisia and larvae were reared ex ovo under laboratory conditions. Both egg and triungulin are described and illustrated by SEM and light microscope. The triungulin shows a campodeiform morphology, typical of non phoretic Meloinae. From the comparison between the first instar larvae of Cerocoma, the single other genus of the tribe Cerocomini whose larvae were known, and Diaphorocera, some distinctive characters are recognised. The phylogenetic placement of the tribe Cerocomini within the family is discussed.
Redescription of the marine scuticociliate Glauconema trihymene Thompson, 1966 (Protozoa: Ciliophora): life cycle and stomatogenesis
Authors: MA HONGWEI , SONG WEI B. , WARREN ALAN , ROBERTS DAVID , GONG JUN , AL-RASHEID KHALED A.S.
Published: May 2019

The transformation from trophont to tomite, morphology, and stomatogenesis during asexual division of the marine ciliate Glauconema trihymene Thompson, 1966 were studied using protargol and Chatton–Lwoff silver nitrate impregnation. An improved diagnosis for the genus Glauconema is suggested: Parauronematidae with polymorphic life cycle comprising trophont, tomite and cyst: buccal apparatus dimorphic, membranelles 1 and 2 closely opposed in trophont while well separated in tomite; paroral membrane uniform, extending anteriorly to midway of membranelle 2; single caudal cilium present; conspicuous glabrous frontal plate. Morphological redescription and stomatogenetic studies were made for G. trihymene. Stomatogenesis in G. trihymene is characterized by: paroral membrane and scutica in the opisthe originate from the anterior part of the parental paroral membrane; membranelles 1 and 2 in the opisthe derive from the posterior part of the parental paroral membrane; the major part of the proliferated scutica develops into membranelle 3 with only a small part comprising several kinetosomes joining in the formation of membranelle 2. Several stages of the transformation from trophont to tomite were also observed. This process starts from an anarchic field, which originates from the whole parental paroral membrane. These develop into two primordia that generate the paroral membrane and three new membranelles, respectively. The three parental membranelles are resorbed or join in the formation of the new membranelles, while the scutica is retained and does not take part in the transformation. The genus Urocryptum Pérez-Uz & Guinea, 2001 is considered a junior synonym of Glauconema and U. tortum is hence transferred to the genus Glauconema as G. tortum (Maupas, 1883) nov. comb.
Two new species and new records of Psychoda Latreille (Diptera: Psychodidae: Psychodinae) from Brazil, with comments on supraspecific classification of the genus
Authors: BRAVO FREDDY , CORDEIRO DANILO , CHAGAS CINTHIA
Published: May 2019

Two new species of Brazilian Psychoda Latreille are described, and Psychoda alternata Say and P. zetoscota Quate are recorded for the first time from Brazil. Psychoda divaricata Duckhouse, already described from southern Brazil, was recorded in the northeastern part of that country, as well as in the eastern Amazon region. The supraspecific classification proposed for the species of Psychoda according to Quate (= Psychodini of Jeñek) are discussed. A new classification is suggested that considers only one genus, Psychoda, divided into 12 subgenera: subgenus Psychoda Latreille, subgenus Copropsychoda Vaillant, subgenus Falsologima Jeñek & Harten, subgenus Psychodula Jeñek, subgenus Psychomora Jeñek, subgenus Psychana Jeñek & Harten, subgenus Logima Eaton, subgenus Tinearia Schellenberg, subgenus Chodopsycha Jeñek, subgenus Ypsydocha Jeñek, subgenus Psychodocha Jeñek, and subgenus Psycha Jeñek. A list of the Psychoda species from Latin America and the Caribbean region is presented.

A new species of pitviper of the genus Popeia (Squamata: Viperidae) from Pulau Tioman, Pahang, West Malaysia
Authors: GRISMER L. LEE , GRISMER JESSE L. , MCGUIRE JIMMY A.
Published: May 2019

We describe a new species of pitviper Popeia buniana from Pulau Tioman, Pahang State, West Malaysia based on it having unique aspects of scalation, body proportions, and color pattern. Its long, thin body is in contrast with the shorter, more robust bodies of other arboreal pitvipers, suggesting it may be an active forager rather than an ambush feeder. Its close relationship to P. barati and P. sabahi of Sumatra and Borneo, respectively, rather than with species of the adjacent Malay Peninsula is in accord with biogeographic patterns of other flora and fauna endemic to the islands of the Outer Arc of the Seribuat Archipelago.

Revision of the Traumatomutilla americana species group (Hymenoptera: Mutillidae)
Authors: BARTHOLOMAY PEDRO R. , WILLIAMS KEVIN A. , LOPEZ VINICIUS M. , OLIVEIRA MARCIO L.
Published: May 2019

Traumatomutilla is a diverse genus of Neotropical velvet ants (Mutillidae). Here we revise the T. americana species group, recognizing three species. Mutilla dubia Fabricius, 1804, M. simulans Smith, 1855, M. albata Smith, 1879, and M. obsoleta (Klug, 1821) are proposed as junior synonyms of Traumatomutilla americana (Linnaeus, 1758). Traumatomutilla maula Casal, 1969, Ephuta punctosignata André, 1906, Mutilla latevittata Cresson, 1902, and M. oculifera Smith, 1855 are proposed as junior synonyms of Traumatomutilla quadrum (Klug, 1821). Mutilla acara Cresson, 1902, M. polita Smith, 1855, M. gemina Gerstaecker, 1874, M. trinacria Gerstaecker, 1874, M. lasiogastra Burmeister, 1875, and M. cuyana Burmeister, 1875 are proposed as junior synonyms of Traumatomutilla ocellaris (Klug, 1821). Traumatomutilla bellifera (Gerstaecker, 1874) is transferred to the T. trochanterata species-group; T. lunigera (Gerstaecker, 1874) and T. compar (André, 1898) are transferred to the T. inermis species-group. Both sexes are redescribed for all species. Notes on the biology and host association for T. ocellaris are provided. Finally, identification keys to the species and color forms of the T. americana group are provided.

Published: May 2019

The monophyletic, dung beetle subfamily, Scarabaeinae, has a long history of subdivision into tribes and subtribes represented by groups of genera unified by designated characters. Various tribal names have been proposed although only 11 or 12 were considered valid in recent reviews. Three of these 12 tribes have now been invalidated due to extensive polyphyly indicated by both morphological and molecular phylogenies. Although partial revision of tribal classification was proposed in the most recent global molecular phylogeny of the subfamily, this was primarily limited to redefinition of membership or provision of support for pre-existing tribes. Complete revision was not attempted as the phylogeny examined interrelationships between only ~52% of the valid described genera. It was also hampered by inconsistencies in topology using different analytical methods, weakened by limited bootstrap support for many basal nodes, as well predicting several phylogenetic relationships that seemed anomalous with regards to biogeographical hypotheses. Nevertheless, using this phylogeny, we propose further revision of tribal classification in a clade of primarily African genera included within a group defined as “basal Scarabaeinae”. Using three different methods, the sister lineages of this clade were consistently recovered, mostly with strong bootstrap support for their molecular relatedness. Therefore, we provide a number of defining morphological characters to support their proposed designation as three new tribes: Byrrhidiini, Endroedyolini and Odontolomini. We also discuss approaches to a full tribal revision as well as the implications for historical biogeography of the Scarabaeinae.
Recommended abbreviations for the names of genera of the phylum Tardigrada

Published: May 2019

When listing the tardigrade species found in a study, the general practice is to sort the list alphabetically or taxonomically by genus. The first time a genus name is used it is spelled out and then it is abbreviated with the first letter of the genus followed by a full stop (period) until a different genus is encountered. This practice works for both a paragraph and a table listing and has been used by tardigrade researchers as far back as Schultze (1834). In the last monograph, Ramazzotti & Maucci (1983) presented a listing of the 52 generic abbreviations they used. We present an updated list of unambiguous abbreviations consistent with the International Code of Zoological Nomenclature (ICZN) for the now 137 recognized tardigrade genera.

We describe a new species of rock gecko of the genus Cnemaspis from Java, Indonesia, representing the first record of the genus for this Island. The new species was collected from the southern slopes of Gunung Muria, a dormant volcano in Central Java. The new species is easily distinguished from all congeners by having a maximum SVL of 58.1 mm in males and 56.9 mm in females; a pair of sharp conical tubercle clusters on the occiput; a warty bridge on the nuchal loop, extending from the upper tympanum and curving to the nape; dorsal tubercles not linearly arranged; 18–20 paravertebral tubercles; postmentals separated by one scale; gular, pectoral and abdominal scales, ventral scales of fore- and hindlimbs, and subcaudal scales keeled; no tubercles on lower flank; precloacal and femoral pores absent; enlarged submetacarpal scales present on the first digit of the manus; 38–40 ventral scales; 31–35 lamellae under fourth toe; two postcloacal tubercles on each side; enlarged median subcaudal scales row present; caudal tubercles encircling tail; and a sexually dimorphic ventral color pattern, with males having a yellow belly and females white and the ventral surface of the tail in males yellow proximally changing to white at mid-length, whereas in females, alternating black and white rings completely encircle the tail, which is black distally.
Reduction in Northern Midlatitude 2-m Temperature Variability due to Arctic Sea Ice Loss
Authors: Collow Thomas W. , Wang Wanqiu , Kumar Arun
Published: May 2019

In this study, we investigate links between Arctic sea ice loss and the variability of 2-m temperatures over a 6-month period (November–April) over two domains centered over northern Eurasia and northern North America. Based on data from the Climate Forecast System Reanalysis (CFSR), there has been an increase (a decrease) in recent seasonal temperature variability over Eurasia (North America), which can be attributed to cooling (warming) during the winter months. Decreases in the intraseasonal variability of temperature anomalies, however, are noted in both regions for the November–April period. This study investigates the role of different forcings on the changes seen in the reanalysis product using Atmospheric Model Intercomparison Project simulations forced with repeating sea surface temperature, sea ice, and carbon dioxide concentration relative to climatologies from two different base periods, 1981–90 and 2005–14. The seasonal temperature and intraseasonal anomaly variabilities are examined, and we find that only the simulations with reduction in sea ice (2005–14 base-period sea ice concentration) produce significant decreases in intraseasonal temperature anomaly variability over these regions, agreeing with the CFSR analysis. Runs that reduce sea ice also result in a significant decrease in the frequency and magnitude of extreme warm and cold temperature anomalies. It is proposed that the weakened latitudinal temperature gradient, resulting from decreased sea ice, leads to reduced meridional temperature advection variability, which in turn contributes to the reduction in the variability of temperature anomalies.
Probabilistic Flood Forecasting Using Hydrologic Uncertainty Processor with Ensemble Weather Forecasts
Authors: Han Shasha , Coulibaly Paulin
Published: May 2019

Recent advances in the field of flood forecasting have shown increased interests in probabilistic forecasting as it provides not only the point forecast but also the assessment of associated uncertainty. Here, an investigation of a hydrologic uncertainty processor (HUP) as a postprocessor of ensemble forecasts to generate probabilistic flood forecasts is presented. The main purpose is to quantify dominant uncertainties and enhance flood forecast reliability. HUP is based on Bayes’s theorem and designed to capture hydrologic uncertainty. Ensemble forecasts are forced by ensemble weather forecasts from the Global Ensemble Prediction System (GEPS) that are inherently uncertain, and the input uncertainty propagates through the model chain and integrates with hydrologic uncertainty in HUP. The bias of GEPS was removed using multivariate bias correction, and several scenarios were developed by different combinations of GEPS with HUP. The performance of different forecast horizons for these scenarios was compared using multifaceted evaluation metrics. Results show that HUP is able to improve the performance for both short- and medium-range forecasts; the improvement is significant for short lead times and becomes less obvious with increasing lead time. Overall, the performances for short-range forecasts when using HUP are promising, and the most satisfactory result for the short range is obtained by applying bias correction to each ensemble member plus applying the HUP postprocessor.
Lagrangian Description of Air Masses Associated with Latent Heat Release in Tropical Storm Karl (2016) during Extratropical Transition

Published: May 2019

Extratropical transition (ET) of tropical cyclones involves distinct changes of the cyclone’s structure that are not yet well understood. This study presents for the first time a comprehensive Lagrangian description of structure change near the inner core. A large sample of trajectories is computed from a convection-permitting numerical simulation of the ET of Tropical Storm Karl (2016). Three main airstreams are considered: those associated with the inner-core convection, inner-core descent, and the developing warm conveyor belt. Analysis of these airstreams is performed both in thermodynamic and physical space. Prior to ET, Karl is embedded in weak vertical wind shear and its intensity is impeded by excessive detrainment from the inner-core convection. At the start of ET, vertical shear increases and Karl intensifies, which is attributable to reduced detrainment and thus to the formation of a well-defined outflow layer. During ET, the thermodynamic changes of the environment impact Karl’s inner-core convection predominantly by a decrease of θe values in the inflow layer. Notably, notwithstanding Karl’s weak intensity, its inner core acts as a “containment vessel” that transports high-θe air into the increasingly hostile environment. Inner-core descent has two origins: (i) mostly from upshear-left above 4-km height in the environment and (ii) boundary layer air that ascends in the inner core first and then descends, performing rollercoaster-like trajectories. At the end of the tropical phase of ET, the developing warm conveyor belt comprises air masses from several different source regions, and only partly from the cyclone’s developing warm sector, as expected for extratropical cyclones.
Atmospheric Composite Sounding Analysis as a Forecasting Tool for Ozone Accumulation in a Semiarid Metropolitan Area during the North America Monsoon: Phoenix, Arizona
Authors: Malloy Jonny William , Cerveny Randall S.
Published: May 2019

Phoenix, Arizona, observes a high summertime frequency for daily maximum 8-h ozone averages (DMO8) exceeding 70 parts per billion, resulting in nonattainment status by the U.S. Environmental Protection Agency. This study discusses the use of composite atmospheric sounding analysis (constructing average sounding conditions for specific recurring events) to forecast different air quality index daily ozone classifications, including “good,” “moderate,” and collectively categories exceeding the 2015 ozone standard. Composite sounding analysis, using the Phoenix 1200 UTC (0500 LST) rawinsonde data (2006–17), identifies “pollutant dispersion windows” for ozone accumulation or dispersal for Phoenix during the North American monsoon (July and August period). A favorable ozone exceedance atmosphere is associated with a “Four Corners high” synoptic pattern bringing relatively light winds at and below 700 hPa (≤4.5 ms−1) and higher easterly winds above (≤12.3 ms−1). Healthy ozone days (good category) are common when Pacific low pressure troughing over the western United States creates deep and faster westerly flow above the surface reaching speeds of 6.7 (19.5) m s−1 by 700 (200) hPa. Surprisingly, large standard deviations over 10°C for dewpoint temperature at midlevels (500–400 hPa) were determined for all three daily ozone classification ranges used in this study. Additionally, modest temperature deviations and mean differences are noted at significant pressure levels. Consequently, wind speed and direction are better indicators when forecasting ozone accumulation potential. These results are pertinent to air quality meteorologists responsible for disseminating ozone forecasts for heavily urbanized areas of the U.S. Southwest.
Why Women Veterans Do Not Use VA-Provided Health and Social Services: Implications for Health Care Design and Delivery
Authors: Evans Elizabeth A. , Tennenbaum Dawn L. , Washington Donna L. , Hamilton Alison B.
Published: May 2019

Background: The Veterans Administration (VA) is transforming its historically male-dominated health care system to better serve women veterans, few of whom, nevertheless, use VA health care. We describe the factors affecting women veterans’ use of VA-provided health care. Methods: We conducted in-person interviews with 22 women veterans in Los Angeles, California, from 2013 to 2015 who received some non-VA health care. Using grounded theory, we inductively identified the major themes and selected illustrative quotations. Results: Why women veterans do not use VA health care is shaped by factors related to the safety, quality, and value of health care, including poor linkage to VA services during and after military service, limited knowledge and inaccurate beliefs regarding eligibility for VA services, bureaucratic barriers impeding receipt of VA care, VA environments triggering memories of negative military experiences, negative interpersonal experiences with VA staff, and perceiving VA settings as unsafe, ill-equipped to address addiction, and insensitive to women-specific needs and preferences. Women are attracted to VA health care for its whole health care capacity, peer social support, and proactive clinicians. Conclusion: Findings can inform improvements to VA health care design and delivery, thereby bolstering those aspects of VA care that women veterans value while reducing health care utilization barriers.
The Bright Side of Having an Enemy
Authors: Harutyunyan Mushegh , Jiang Baojun
Published: May 2019

Conventional wisdom suggests that more intense competition will lower firms’ profits. The authors show that this may not hold in a channel setting with exclusive retailers. They find that a manufacturer and its retailer can both become worse off if their competing manufacturer and retailer with quality-differentiated products exit the market. Put differently, in a channel setting, more intense competition can be all-win for the manufacturer, the retailer, and the consumers. Interestingly, a high-quality manufacturer can benefit from an increase in its competitor’s perceived quality (e.g., due to favorable product reviews from consumers or third-party rating agencies). In other words, a manufacturer may prefer a strong rather than a weak enemy, and the manufacturer can have an incentive to help its competitor improve product quality or remain in the market. Furthermore, the authors show that a multiproduct monopolist manufacturer with an exclusive retailer may make higher profits by spinning off a product into a competing manufacturer that has its own retail channel, even without accounting for any proceeds from the spinoff.
Validation of a Brief Form of the Supervisory Working Alliance Inventory
Authors: Sabella Scott A. , Schultz Jared C. , Landon Trenton J.
Published: May 2019

The Supervisory Working Alliance Inventory–Trainee Form (SWAI-T) is among the most frequently used instruments for measuring the quality of supervisor–supervisee relationships within counselor supervision. Although the full-scale SWAI-T instrument has proven utility, there are instances when a shorter form may be useful for research and field applications. The current study used secondary data from a pair of cross-sectional studies to test the utility of a brief form of the SWAI-T in a two-step process: (a) reduction of the SWAI-T based on item analyses from an electronic survey of 87 rehabilitation counselors working in a Western state vocational rehabilitation agency and (b) an initial validation study of the instrument using electronic survey responses from a national sample of 228 rehabilitation counselors working in private rehabilitation. The resultant 5-item scale showed evidence of high internal consistency, convergent validity, and minimal differences in psychometric properties relative to the full-scale instrument. An abbreviated supervisory working alliance scale offers practical advantages for select research purposes and for continuous evaluation of supervisory relationships in field environments.
A Multivariate Analysis of Diachronic Variation in A Bunch of noun: A Construction Grammar Account
Authors: Shao Bin , Cai Yingying , Trousdale Graeme
Published: May 2019

On the basis of data retrieved from the Corpus of Historical American English, this paper provides a multivariate analysis of diachronic change in collocations of the sequence a bunch of followed by a noun in the Late Modern and contemporary English periods. Our results show that (1) the partitive semantics shifts in the period from the 1910s to the 1960s from the original dominant meaning ‘bundle’ to ‘group,’ while the quantifier function/‘large quantity’ meaning of bunch becomes more entrenched from the 1970s onwards, though the three meanings continue to co-exist in the contemporary language; and (2) there exist statistically significant correlations between semantic, pragmatic, and discourse properties of the noun collocates in the partitive and quantifier constructions. While much work on diachronic construction grammar is concerned with the question of how new constructions come into being, the present article complements such research by providing a detailed account of the nature of persistence of the earlier partitive construction and the embedding and gradual entrenchment of the newer quantifier construction. It therefore addresses the consequences of “constructionalization” on a source construction, and the nature of frequency effects in “post-constructionalization” changes.
