Nudging Technology Use: Descriptive and Experimental Evidence from School Information Systems
Authors: Bergman Peter
Published: June 2019

As schools are making significant investments in education technologies it is important to assess whether various products are adopted by their end users and whether they are effective as used. This paper studies the adoption and ability to promote usage of one type of technology that is increasingly ubiquitous: school-to-parent communication technologies. Analyzing usage data from a Learning Management System across several hundred schools and then conducting a two-stage experiment across fifty-nine schools to nudge the use of this technology by families, I find that 57 percent of families ever use it, and adoption correlates strongly with measures of income and student achievement. Although a simple nudge increases usage and modestly improves student achievement, without more significant intervention to encourage usage by disadvantaged families, these technologies may exacerbate gaps in information access across income and performance levels.
The Compositional Effect of Rigorous Teacher Evaluation on Workforce Quality
Authors: Cullen Julie Berry , Koedel Cory , Parsons Eric
Published: June 2019

We study how the introduction of a rigorous teacher evaluation system in a large urban school district affects the quality composition of teacher turnovers. With the implementation of the new system, we document increased turnover among the least effective teachers and decreased turnover among the most effective teachers, relative to teachers in the middle of the distribution. Our findings demonstrate that the alignment between personnel decisions and teacher effectiveness can be improved through targeted personnel policies. However, the change in the composition of exiters brought on by the policy we study is too small to meaningfully impact student achievement.
Upskilling: Do Employers Demand Greater Skill When Workers Are Plentiful?
Authors: Modestino Alicia Sasser , Shoag Daniel , Ballance Joshua
Published: June 2019

Using a proprietary database of online job postings, we find that education and experience requirements rose during the Great Recession. These increases were larger in states and occupations that experienced greater increases in the supply of available workers. This finding is robust to controlling for local demand conditions and firm [Formula: see text] job-title fixed effects and using a natural experiment arising from troop withdrawals as an exogenous shock to labor supply. Our results imply that the increase in unemployed workers during the Great Recession can account for 18% to 25% of the increase in skill requirements between 2007 and 2010.
The Time-Varying Effect of Monetary Policy on Asset Prices
Authors: Paul Pascal
Published: June 2019

This paper studies how monetary policy jointly affects asset prices and the real economy in the United States. I develop an estimator that uses high-frequency surprises as a proxy for the structural monetary policy shocks. This is achieved by integrating the surprises into a vector autoregressive model as an exogenous variable. I use current short-term rate surprises because these are least affected by an information effect. When allowing for time-varying model parameters, I find that compared to the response of output, the reaction of stock and house prices to monetary policy shocks was particularly low before the 2007–2009 financial crisis.
POLITICIZING REPRODUCTION IN COMPARATIVE PERSPECTIVE: OTTOMAN, TURKISH, AND FRENCH APPROACHES TO ABORTION LAW
Authors: Miller Ruth
Published: June 2019

In this essay I discuss modern abortion legislation in the Ottoman Empire, Turkey, and France. Using late nineteenth and early twentieth century fears of population decline and "race suicide" as a starting point, the first half of the essay examines the relationship between nationalist or authoritarian state formation and the criminalization of abortion in all three states. The second half of the paper discusses the gradual de-criminalization of abortion after the Second World War and its relationship to twentieth century rights rhetoric. In this essay I argue that both the criminalization and de-criminalization of abortion in the Ottoman Empire, Turkey, and France were central to modern citizenship formation, each process equally essential to the increasing politicization of reproductive behavior over the modern period. At the same time, I also argue that legislators in all three states looked back to unique "traditions" to serve as foundations for their post-eighteenth century laws—Ottoman and Turkish jurists making use of medieval and early modern debates in the Islamic world surrounding abortion and French jurists making use of an equally well-established Catholic tradition.
A Fatwa and Its Dialectics: Contextualizing the Permissibility of Mortgages in Stockholm
Authors: Shavit Uriya
Published: June 2019

In 1999, the European Council for Fatwa and Research issued a fatwa that legitimized mortgages for Muslims in Europe who are not homeowners. While this groundbreaking text gained some academic attention, little has been written about its reception and impact. Through a field study in three Islamic centers in Stockholm, this article examines the conflicting opinions about this religious decision among imams and mosque attendees and demonstrates that both the most ardent supporters of the European Council and its staunchest critics engage with the legitimization of mortgages in ways that are independent and original and correspond with their personal understanding of the situation of local Muslims.
Vocables and Microtones in Ancient Greek Music
Authors: D’Angour Armand
Published: June 2019

This article discusses ways in which non-lexical utterances are linked in ancient Greek music to the representation of musical phrases. It first considers the possible use of ‘vocables’ in ancient Greek, i.e. vocal utterances lacking lexical content which may be substituted for the rhythms of a song for the purpose of the instruction or transmission of music. A system of vocables (distinct from solmization) outlined by Aristides Quintilianus is investigated to see if it can be shown to be related to principles of vowel pitch modification, whereby phonetically ‘high’ vowels tend to be enunciated at a higher pitch than ‘low’ ones. Since such variances could be heard in the context of microtonal music as creating wholly different musical notes, the Orestes papyrus is examined in detail to see if the enharmonic musical setting is affected in any way by principles of vowel pitch modification, with the conclusion that it is.
‘Without Timotheus, Much of Our Melopoiia Would not Exist; But without Phrynis, There Wouldn’t Have Been Timotheus’
Authors: Lynch Tosca
Published: June 2019

In this paper, I offer a close discussion of the musical innovations attributed to Phrynis, Timotheus and other ‘New Musicians’ mentioned in a famous fragment of Pherecrates’ Chiron, interpreting this fascinating passage in the light of the extant evidence about ancient harmonic theory and practice, as well as the latest research findings. More specifically, I shall advance a new hypothesis concerning the nature of Phrynis’ innovative ‘twister’ (strobilos): producing a special bending (kampē) of a semitone, this gadget allowed Phrynis to combine five different harmoniai (Dorian, Phrygian, Lydian, Iastian and ‘Loose Lydian’) in one and the same twelve-string tuning. Making a subtle modification to this device, Timotheus further expanded the harmonic palette of his twelve-string kithara, introducing the lamenting aulos-mode par excellence, the Mixolydian, into the realm of lyre music. Philoxenus increased this system by adding an extra string, reaching the 13-step arrangement that is at the heart of Aristoxenian harmonic theory.
Echoes of the Rejection of the Aulos in Augustan Poetry
Authors: Wyslucha Kamila
Published: June 2019

Athenian elites of the late fifth century BC rebelled against aulos-playing as part of the school curriculum and launched a socio-cultural campaign against the instrument. Echoes of this ‘anti-aulos’ crusade reverberated in literature in the centuries to follow as motifs of hostility towards aulos music. Ovid (Fasti 6.657-710) and Propertius (2.30b) engage in this discourse, largely disregarding the motives of the Athenians for spurning the instrument; instead they embed the rejection myths in their poetical programmes in the context of their precarious relationship with Augustan authority. This paper argues that while both poets oppose the rejection of the doublepipes, they do so for entirely different reasons. Although the negative image of the aulos is present in Latin literary sources, it is largely disconnected from the substantial role of the instrument in Roman musical culture.
Five new Achnanthidiaceae species (Bacillariophyta) from Jiuzhai Valley, Sichuan Province, Southwestern China
Authors: YU P. , YOU Q-M. , PANG W-T. , CAO Y. , WANG Q-X.
Published: June 2019

Five new species are described in this study: Achnanthidium jiuzhaienis sp. nov., Achnanthidium epilithica sp. nov., Achnanthidium limosua sp. nov., Achnanthidium subtilissimum sp. nov., and Kolbesia sichuanenis sp. nov. Classification was based on light microscopy (LM) and scanning electron microscopy (SEM). A. jiuzhaienis sp. nov. belongs to the “A. pyrenaicum complex” of the genus Achnanthidium, this classification was based on certain characteristics, such as the possession of transpically-elongated areolae and deflected external distal raphe fissures. A. epilithica sp. nov., A. limosua sp. nov., and A. subtilissimum sp. nov. belong to the “A. minutissimum complex” of the genus Achnanthidium, this classification was based on certain characteristics, such as the possession of straight external distal raphe fissures and round or elliptical areolae. Kolbesia sichuanenis sp. nov. was found to belongs to the Kolbesia genus, based on its elongated areolae and striae comprised of one macroareola. All five species were sufficiently different from other similar species to be considered unique separate species based on their valve outline, shape of the axial and center areas, and density of striae of each taxon. These new species derived from the epilithic and epiphytic collections of four alkaline lakes in Jiuzhai Valley, Sichuan Province, Southwest China.
A review of the Australian skate genus Pavoraja Whitley (Rajiformes: Arhynchobatidae)
Authors: LAST PETER R. , MALLICK STEPHEN , YEARSLEY GORDON K.
Published: June 2019

The Australian endemic skate genus Pavoraja Whitley, which contains six species including two valid nominal species (P. alleni and P. nitida) and four new species (P. arenaria sp. nov., P. mosaica sp. nov., P. pseudonitida sp. nov. and P. umbrosa sp. nov.), is redefined based on additional material. Members of the group occur primarily on the outer continental shelf and upper slope in both temperate and tropical Australian seas. The species are strongly partitioned geographically with smallto medium-scale ranges. Pavoraja arenaria is known to have a broad southern distribution but none is widespread in the Australian region. Only two species pairs, P. nitida and P. arenaria (off southern Australia), and P. mosaica and P. pseudonitida (off northeastern Australia), are known to be sympatric. New information is provided for the two nominal taxa, and the four new species are formally described and figured. Skeletal characteristics are described and illustrated, and a key to species is provided. Members of the genus differ primarily in colour pattern, squamation, morphometrics, meristics, and anatomical structure. The relationships of the genus Pavoraja to other arhynchobatid skates are discussed briefly.
On the spider genus Weintrauboa (Araneae, Pimoidae), with a description of a new species from China and comments on its phylogenetic relationships
Authors: HORMIGA GUSTAVO
Published: June 2019

Weintrauboa yele new species (Pimoidae) is described and illustrated based on specimens collected in China. The taxonomic status and distribution of Weintrauboa insularis (Saito, 1935) new combination and of W. chikunii (Oi, 1979) are discussed and the former species is illustrated based on specimens from the Sakhalin islands. Parsimony analysis of morphological characters provides support for the monophyly of Weintrauboa and for its sister group relationship to the genus Putaoa Hormiga and Tu, 2008. Some comments on the phylogenetic placement of the recently erected family “Sinopimoidae” are provided.

Description of eleven new Triplectides species (Trichoptera: Leptoceridae) from New Caledonia
Authors: MALM TOBIAS , JOHANSON KJELL ARNE
Published: June 2019

The Oceanian country of New Caledonia has been shown to have a great diversity of Trichoptera, but prior to this work only 3 species from the large Leptoceridae genus Triplectides were known from there. Extensive sampling on the main island, Grande Terre, revealed 11 new species in the genus, as well as a male of the seemingly widespread species Triplectides australis. These 11 new species are here described and illustrated, and a key to males of the New Caledonian Triplectides species is provided. The new species are: T. mouiensis, new species; T. abnormalis, new species; T. minutus,new species; T. noumeiensis, new species; T. tigrinus, new species; T. koghiensis, new species; T. wardi, new species; T. nathaliae, new species; T. mariannae, new species; T. dawnae, new species; T. aequalichelatus, new species. Fifteen species within the genus are now known from New Caledonia; relative to land mass, this is a high diversity compared to the 25 species recorded from Australia.

Ephemeroptera and Plecoptera biodiversity in central Patagonia, Chubut province, Argentina
Authors: PESSACQ PABLO , MISERENDINO MARÍA LAURA
Published: June 2019

Aquatic insects in Central Patagonia (Andean region), Argentina, have received poor and fragmentary attention. In this paper we present the first preliminary inventory of Plecoptera and Ephemeroptera taxa for the area and include seasonal records of adult stages. We incorporate a set of environmental features for the sampling sites and biotopes as well as the main characteristics of the phytogeographical and biogeographical areas in which the species were found. Twelve species and eight genera of mayflies and eleven species and five genera of stoneflies are recorded for the first time in Chubut province. The stoneflies Neofulla biloba (Aubert), Alfonsoperla flinti McLellan & Zwick, Austronemoura eudoxiae Froehlich, Chilenoperla semitincta Illies, Neonemura illiesi Zwick and Potamoperla testacea Vera, and the mayflies Andesiops ardua (Lugo-Ortiz & McCafferty), Chaquihua bullocki Navás. And the family Oniscigastridae are new records for Argentina. The genera Americabaetis Kluge, Camelobaetidius Demoulin and Traverella Edmunds are confirmed for first time in the Andean region (Central Patagonia province) and four Plecoptera and two Ephemeroptera species constitute new records for the Patagonian steppe. We also include two new records for Ephemeroptera and Plecoptera for the Santa Cruz province. We reinforce the idea that patagonian aquatic environments have a highly specialized and complex insect fauna which can be correlated with biogeographical aspects but also with a great environmental heterogeneity.
Revision of the Paleartic species of the genus Ochthebius Leach (Coleoptera: Hydraenidae) XXIV. Description of Ochthebius (Asiobates) sanabrensis n. sp. from northwestern Spain
Authors: VALLADARES LUIS F. , JÄCH MANFRED A.
Published: June 2019

In the Palearctic region, the hydraenid subgenus Asiobates Thomson, 1859 comprises two species groups (Jäch, 1990): the O. minimus Fabricius group and the O. bicolon Germar group. The O. bicolon group is quite diverse in the Iberian Peninsula (12 species) displaying a high level of endemism (six Iberian endemic species). In contrast, only two Iberian species of the O. minimus group are known to date, with both rather widely distributed in the western Palearctic Region: O. (Asiobates) aeneus Stephens, 1835 and O. (A.) minimus (Fabricius, 1792). A new species, apparently endemic to the northwestern Iberian Peninsula, is now added to this group.

Published: June 2019

Five new species of Myrsidea parasitic on members of the avian family Thamnophilidae are described herein. They and their type hosts are Myrsidea klickai ex the Northern Slaty Antshrike, Thamnophilus punctatus (Shaw, 1809), M. dacostai ex the Barred Antshrike, Thamnophilus doliatus (Linnaeus, 1764), M. spellmani ex the Spotted Antbird, Hylophylax naevioides (Lafresnaye, 1847), M. milleri ex the Rufous-throated Antbird, Gymnopithys rufigula (Boddaert, 1783), and M. mayermae ex the White-faced Antbird, Pithys albifrons (Linnaeus, 1766). A portion of the mitochondrial COI gene for some of these and other species of Myrsidea was sequenced to compare genetic divergences.
Taxonomy of European Damaeidae (Acari: Oribatida) I. Kunstidamaeus Miko, 2006, with comments on Damaeus sensu lato
Authors: MIKO LADISLAV , MOUREK JAN
Published: June 2019

The diagnosis of the genus Kunstidamaeus Miko, 2006 is given and a new generic concept within Damaeus sensu lato is proposed. Epidamaeus, Kunstidamaeus and Spatiodamaeus are given generic status, whereas Adamaeus, Paradamaeus and the nominal subgenus Damaeus s. stricto are considered to be subgenera of the genus Damaeus. The type species K. lengersdorfi (Willmann, 1932) including the immature stases is redescribed and its geographic distribution and ecology is discussed. The neotype of K. lengersdorfi is designated. Together with the type species, the genus Kunstidamaeus includes seven known European species: K. tenuipes (Michael, 1885), K. tecticola (Michael, 1888), K. nivalis (Kulczynski, 1902), K. nidicola (Willmann, 1936), K. diversipilis (Willmann, 1951), K. granulatus (Willmann, 1951), and K. longisetosus (Willmann, 1953).
Confocal microscopy applied to water mite taxonomy with the description of a new genus of Axonopsinae (Acari, Parasitengona, Hydrachnidia) from Central America
Authors: VALDECASAS ANTONIO G.
Published: June 2019

Vagabundia sci n. gen. n. sp. of the subfamily Axonopsinae is proposed and described. Confocal Laser Scanning Microscopy, not previously applied to water mite taxonomy, allowed the acquisition and posterior processing of clean optical slices. The new species is compared to other mites that have been described as ‘Axonopsella-like’. Vagabundia sci n. sp. is named after the Science Citation Index, a sociological tool that, as explained in the text, has done more harm than good to the population of taxonomists.

Published: June 2019

We describe Pristimantis gagliardoi, a new medium sized (SVL 19.06–33.64 mm) Pristimantis species from the Andean forests of southeastern Ecuador. This species is referred to the P. unistrigatus group. It differs from other members in the unistrigatus group by the presence of large conical tubercles on the eyelid and heel, small conical ulnar and tarsal tubercles, suprascapular dermal ridges, and bronze iris.
"Frog Search": Synonymy of Phrynobatrachus nigripes Pickersgill, 2007, plus other comments and corrections
Authors: PICKERSGILL MARTIN
Published: June 2019

In 2007 I published the book “Frog Search—Results of Expeditions to Southern and Eastern Africa”. My aim was to document the results of nearly 10 years of frog research in southern and eastern Africa. It included a number of proposed taxonomic amendments as well as the descriptions of 10 new species. Shortly after publication I realised that one of these new species Phrynobatrachus nigripes Pickersgill, 2007 was in fact the juvenile form of Phrynobatrachus pakenhami Loveridge, 1941. Since I was too late to include errata in the book itself, I take this opportunity to effect this and further amendments and corrections relating to “Frog Search”.

Three new species of Hyposmocoma (Lepidoptera, Cosmopterigidae) from the Hawaiian Islands, based on morphological and molecular evidence
Authors: SCHMITZ PATRICK , RUBINOFF DANIEL
Published: June 2019

The Cosmopterigid genus Hyposmocoma (Lepidoptera, Cosmopterigidae) is endemic to Hawaii and contains over 350 recognized species, though only one new species has been described in the past 62 years. We describe and illustrate three new species of Hyposmocoma: Hyposmocoma kaupo sp. nov. from the island of Maui, H. kapakai sp. nov. from Oahu, and H. kaikuono sp. nov. from Molokai, all known from both sexes, and all apparently single-island endemics. The casemaking larvae of all three species feed on lichen and organic debris on dry rocks in open or partly forested habitat. While morphological differences among these three species are small, genetic divergence across parts of the mitochondrial gene cytochrome oxidase I and the nuclear genes elongation factor 1 indicate universally deep divergence, making these taxa a classic example of sibling species.

Revision of the Ranitomeya fantastica species complex with description of two new species from Central Peru (Anura: Dendrobatidae)
Authors: BROWN JASON L. , TWOMEY EVAN , PEPPER MARK , RODRIGUEZ MANUEL SANCHEZ
Published: June 2019

We describe two new species of poison frogs (genus Ranitomeya) from the central Rio Huallaga drainage and adjacent Cordillera Azul in central Peru. Both species were previously considered to be members of Ranitomeya fantastica, a species described from the town of Yurimaguas, Peru. Extensive sampling of putative R. fantastica (including near-topotypic material) throughout central Peru, and the resulting morphological and phylogenetic analysis has led us to conclude that R. fantastica sensu lato is a complex of three closely related species rather than a single, widely distributed species. The first of these species occurs near the type locality of R. fantastica but bears significant dissimilarity to the original type series and forms a monophyletic clade that is distributed throughout an expansive lowland zone between Rio Huallaga and Rio Ucayali. This species is diagnosable by its brilliant red head and advertisement call differences. The second new species has long been considered a color morph of R. fantastica, although our analysis shows that it is genetically distinct from even adjacent populations of R. fantastica. This species is restricted to the Huallaga Canyon near Chazuta and is primarily diagnosed on the basis of nucleotide sequences, although it does possess additional morphological and vocal characteristics which are distinct from R. fantastica.
First description of the female of Ozyptila utotchkini (Araneae: Thomisidae)
Authors: MARUSIK YURI M. , OMELKO MIKHAIL M.
Published: June 2019

Ozyptila utotchikini Marusik in Marusik and Chevrizov (1990) was described from two male specimens from the Anuchino District of Maritime Province, Far East Russia. Since then it has also been reported from Sikhote-Alin’ Reserve (Marusik & Koponen 2001). Ozyptila utotchkini belongs to the Holarctic O. rauda-group which comprises about 10 species. The examination of both, newly collected material and specimens from museum collections from Maritime Province has uncovered the undescribed female of this species. Although collected previously, it was not known to be conspecific to the male of O. utotchkini, or a member of the O. rauda-group, as it has an unusual epigyne. Recently we recognized that O. utotchkini may represent a junior synonym of O. gasanensis Paik, 1985, known only from female holotype collected in Korea. The holotype of this species is not available (all types deposited in the private collection of K.Y. Paik were lost after his death). The goal of this paper is to describe both sexes of O. utotchkini to allow clarification of the status of the two Far Eastern species, O. gasanensis and O. utotchkini, in the future.

A new livebearing fish, Heterandria tuxtlaensis, from Lake Catemaco, Veracruz, Mexico (Cyprinodontiformes: Poeciliidae)
Authors: MCEACHRAN JOHN D. , DEWITT THOMAS J.
Published: June 2019

A new species of poeciliid fish, Heterandria tuxtlaensis sp. n., is described from Lake Catemaco in southern Veracruz, Mexico. Based on traditional and geometric morphometrics, H. tuxtlaensis differs most substantially from its likely sister species H. bimaculata in possessing short dorsal and caudal fins, a short dorsal fin base composed of fewer fin rays, a more shallow body, and a relatively small basicaudal spot restricted to the area above the mid lateral line. Description of this new species brings the number of known endemics in Lake Catemaco to six. This high level of endemicity complements genetic and geological findings suggesting the lake is ancient and well separated from surrounding fish populations.
Redescription and illustrations of the Centipede, Ectonocryptops kraepelini Crabill, 1977 (Scolopendromorpha: Scolopocryptopidae: Ectonocryptopinae)
Authors: SHELLEY ROWLAND M. , MERCURIO RANDY
Published: June 2019

In 1977, R. E. Crabill, Jr., erected Ectonocryptops for a new Mexican centipede from Colima that he named, E. kraepelini. He placed it in the Cryptopidae, but with 23 pairs of legs and pedal segments, it properly belongs in the                Scolopocryptopidae, subfamily Ectonocryptopinae, according to today's taxonomy (Shelley & Mercurio 2005). Crabill did not provide illustrations, and the holotype and only specimen, supposedly at the American Museum of Natural History, New York, USA (AMNH), was subsequently lost. Consequently, the identity of this centipede was uncertain until we (Shelley & Mercurio 2005) proposed Ectonocryptoides quadrimeropus, n. gen., n. sp., for an anatomically similar form from neighboring Jalisco. Discovery of the latter allowed us to interpret characterizations in Crabill's verbal account of Ectonocryptops kraepelini, and separate generic status seemed warranted because of different numbers of podomeres on the caudal legs, four in Ectonocryptoides quadrimeropus and five in Ectonocryptops kraepelini (Crabill 1977). Repeated and extensive searches in the type and general collections at the AMNH failed to reveal the missing holotype as did ones at the National Museum of Natural History, Smithsonian Institution, Washington, DC, where Crabill was a curator when he described Ectonocryptops kraepelini. The holotype was discovered in the AMNH by the second author in 2005; the cephalic plate & antennae, coxosternum & segments 1–7, and segments 19–23 plus the caudal legs had been dissected, cleared, and mounted on a slide, whereas segments 8–18 were in a vial of alcohol. The slide mount was in extremely poor condition with darkened and cracked medium that was filled with air bubbles and meniscuses such that critical parts could not be clearly viewed. We removed the mounted parts from the slide, placed them in alcohol with the rest of the specimen, and redescribe Ectonocryptops kraepelini and provide, for the first time, illustrations of anatomical features. We also provide new accounts of the subfamily, Ectonocryptoides, and Ectonocryptoides quadrimeropus, so that all subfamilial components are treated in a single publication. Asterisks (*) in the account of Ectonocryptops kraepelini denote items taken from Crabill's (1977) description that we could not confirm.
Redescription of Isotomiella alulu and I. delamarei (Collembola: Isotomidae) with notes on the systematics of the genus and new records from the Neotropics

Two phyletic lineages are outlined within the genus represented by I. minor and I. nummulifer species groups. Diagnostic tables for Isotomiella species based on sensillar patterns and morphological characters of furcula are involved and a dichotomous identification key to the genus is provided. Notes on the systematics and distribution of Isotomiella species are added. New localities for I. granulata, I. nummulifer and I. symetrimucronata from the Neotropics (Mexico, Nicaragua) are given , and records of I. minor are confirmed for Northern and Central Mexico (Nearctic region).
Larval morphology and diagnosis of the Giant Microcaddisfly species, Ugandatrichia spp. (Hydroptilidae: Trichoptera) in Thailand
Authors: LAUDEE PONGSAK
Published: June 2019

Fifth instar larval morphology and ultrastructure of Ugandatrichia kerdmaung Malicky and Chantaramongkol 1991, U. maliwan Malicky and Chantaramongkol 1991, U. honga Olah 1989 and U. hairanga Olah 1989 were investigated. The Ugandatrichia spp. are case bearing and net spinning caddisflies. The presence, number and characteristics of the sclerites on abdominal sterna III, IV, and V can be used to identify the Ugandatrichia species found in Thailand. The larva of U. honga has no sclerites on the abdominal sterna; that of U. hairanga has a sclerite on each of abdominal sterna III, IV, and V; that of U. kerdmuang has a sclerite on each of abdominal sterna IV and V, and that of U. maliwan has six sclerites on abdominal sterna IV and V. SEM micrographs of Ugandatrichia spp. showed that the spherical palpiger has a labial palp, an anterior silk gland opening, and dense bristles anteriorly and inside of its mouth. There are three main types of integument surface: an irregular dome shape which is found on the head, pronotum, mesonotum, and metanotum; a regular dome shape which is found on the membrane between the nota; and an amoeboid, dot shape which is found on the abdominal segments.

Published: June 2019

A landmark-based geometric morphometric approach was used to assess differences in the size and shape of wing among/within three species of the Cheilosia canicularis group (Diptera: Syrphidae): C. canicularis, C. himantopus and C. orthotricha. Wing size and shape variation was observed from 25, 176 and 41 specimens of C. canicularis, C. himantopus and C. orthotricha, respectively, collected from six localities on the Balkan Peninsula. Significant differences in wing size were obtained among the analysed species and canonical variate analysis showed that wing shape was sufficiently different to allow the correct classification of 73% individuals of C. canicularis, 80% of C. orthotricha and 94% of C. himantopus, and clear delimitation of the species pairs C. canicularis/C. orthotricha and C. himantopus/C. orthotricha. In all analysed species, the consistent sex dimorphism in wing shape was observed indicating that female specimens had shorter and broader wings than males. The UPGMA cluster analysis based on squared Mahalanobis distances revealed close accordance with previously published phylogenetic relationships of these species indicated by allozyme and DNA sequence data analysis. Our results suggested that wing parameters contain useful information in quantification phenotypic variation and identification of species in this challenging group for taxonomy and systematics.

Intraspecific morphological variation of Scutovertex sculptus Michael (Acari: Oribatida: Scutoverticidae) and description of its juvenile stages
Authors: PFINGSTL TOBIAS , SCHÄFFER SYLVIA , EBERMANN ERNST , KRISPER GÜNTHER
Published: June 2019

This paper provides a detailed redescription of the adult and the first morphological description of all juvenile stages of Scutovertex sculptus. Specimens from four European countries, Austria, Germany, France and Spain were investigated. The species specific characters are the broadened posterior notogastral setae (lp, h 1 –h 3 ), the slightly broadened anterior notogastral seta (dm), the gastronotic cuticle with irregularly distributed foveae and a thick layer of secretion forming blocs with color dispersive qualities on the posterior half of notogastral region. Minor differences in the shape of notogastral setae and in the thickness of the secreted layer on the posterior gastronotic region were found in specimens from different countries. The investigation of the juveniles of S. sculptus showed that the larva and nymphs can be easily distinguished from those of S. minutus; the lateral setae on tibia I are leaf-shaped in S. sculptus and knife-shaped in S. minutus.

Presumed species synonymy in the genus Allogynaspis Krantz, 2018 (Acari: Macrochelidae)
Authors: KRANTZ G.W.
Published: June 2019

Macrocheles bolivari Iavorschi, 1987, in a volume of invited papers on hypogean invertebrate fauna collected primarily in Venezuela in 1982 during the first Romanian/Venezuelan Biospeleogical Expedition. The volume, “Hypogean and hemiedaphic fauna from Venezuela and other countries of South America. 1” was recently brought to my attention by Bruce Halliday, who recognised the similarity between Iavorschi’s M. bolivari and Allogynaspis flechtmanni Krantz, 2018, recently described from Brazil. Although some important opisthosomatic and gnathosomatic details were omitted from Iavorschi’s description, the nature of the epigynal and dorsal shields (Iavorschi 1987, Figs 1A, B), along with the unusual fixed cheliceral digit dentition (Iavorschi 1987, Fig. 1C), leave little doubt that Macrocheles bolivari is a species of Allogynaspis. However, there are discrepancies between the descriptions of M. bolivari and A. flechtmanni, such that final verification of species synonymy may only be possible if type specimens of these two entities can be compared. Of special significance here are differences in sternal shield morphology and ornamentation (Krantz 2018, Fig. 2; Iavorschi 1987, Fig. 1A), and omission of any mention in Iavorschi’s description of greatly enlarged setae on tarsus IV as described for A. flechtmanni (Krantz 2018, Fig. 6).

The Constitutional Limits of EU Competition Law—United in Diversity
Authors: Townley Chris , Türk Alexander H.
Published: June 2019

The allocation of legislative and executive competences in multilevel governance structures affects who controls norms. Over the last two decades we see a general trend in EU law, towards “flexibility, mixity and differentiation.” Yet many think that EU competition policy and enforcement marches to a different tune. Competence is rarely discussed there and, when it is, most assume that uniformity is desirable. This article discusses the EU constitutional system as it relates to competition policy and enforcement. It investigates what choices the EU Treaties make about diversity. As with many constitutional arrangements, the EU Treaties sometimes leave space for others to decide. In these spaces we advocate answers, based on our understanding of the constitutional settlement between the EU and the Member States. This has major implications for, amongst others: the Commission’s power to relieve the Member States’ national competition authorities (NCAs) of their competence to apply Articles 101 and 102 of the Treaty on the Functioning of the European Union (TFEU); the vires of EU merger control outside of the remit of Articles 101 and 102 TFEU; Commission efforts to make the NCAs more independent of political influence; and the resolution of conflicts between EU and national competition rules.
An Empirical Examination of Impact
Authors: Gupta Kirti , Effraimidis Georgios
Published: June 2019

In February 2015, the Institute of Electrical and Electronics Engineers-Standards Association (IEEE-SA)—one of the largest standards development organizations (SDOs)—adopted highly controversial changes to its intellectual property rights (IPR) policy. It introduced a specific definition of fair, reasonable and nondiscriminatory (FRAND) licensing terms. The aim of this article is to explore how the new patent policy has impacted different aspects of standards development within IEEE. Our analysis focuses on the IEEE 802 LAN/MAN Standards Committee (IEEE 802 LMSC), whose Working Groups have been responsible for the design and development of widely used technologies such as Wi-Fi and Ethernet. The empirical findings suggest a decline in Letters of Assurance, with several patent holders reluctant to license under the new FRAND terms. We also find that the number of new projects initiated (or Project Authorization Requests; PARs) in the intellectual property(IP)-intensive IEEE standards (namely the 802 WGs) has recently decreased, suggesting a potential slowdown of the growth rate of innovation after the policy change.
