Published: June 2019

Background:

Implantable cardioverter-defibrillators (ICDs) are indicated in patients with left ventricular ejection fraction ≤35%, but many eligible patients do not receive this therapy. In this cluster randomized trial, we investigated the impact of a best practice alert (BPA) through the electronic health records on the rates of electrophysiology referrals, ICD implantations, and all-cause mortality in severe cardiomyopathy patients.

Methods and Results:

Providers in the Heart and Vascular Institute (n=106) and in General Internal Medicine (n=89) were randomized to receive or not receive a BPA recommending consideration for ICD implantation. Patients belonging to the BPA and no BPA groups of providers were followed to the end points of electrophysiology referrals, ICD implantations, and all-cause mortality. Between 2013 and 2015, patients with reduced left ventricular ejection fraction were managed by 93 providers in the BPA (n=997 patients) and 102 providers in the no BPA (n=909 patients) groups. Patients in the 2 groups had comparable baseline characteristics. After a median follow-up of 36 months, 638 (33%) patients were referred to electrophysiology, 536 (27%) received an ICD, and 445 (23%) died. Patients in the BPA group were more likely to be referred to electrophysiology (hazard ratio=1.23;
P
=0.026), to receive ICD therapy (hazard ratio=1.35;
P
=0.006), and exhibited a trend towards slightly lower mortality (hazard ratio=0.85;
P
=0.091).

Conclusions:

Delivering a BPA through the electronic health record recommending to providers consideration of ICD implantation when the left ventricular ejection fraction is ≤35% improves the rates of electrophysiology referrals and ICD therapy in patients with severe left ventricular dysfunction.
Prognostic Value of Anxiety Between Heart Failure With Reduced Ejection Fraction and Heart Failure With Preserved Ejection Fraction

Background

Evidence suggests differences in clinical characteristics, causes, and prognoses between heart failure with reduced ejection fraction (
HF
r
EF
) and heart failure with preserved ejection fraction (HFpEF). Most studies have failed to support the prognostic relevance of anxiety in
HF
r
EF
or unclassified
HF
with mean left ventricular ejection fraction <40%. Meanwhile, the association between anxiety and prognoses in
HF
p
EF
remains unexamined. This study compared the prognostic value of anxiety between
HF

and
HF
p
EF
.

Methods and Results

A total of 158 patients with
HF
r
EF
(left ventricular ejection fraction=28.51±7.53%) and 108 patients with HFpEF (left ventricular ejection fraction=64.53±9.67%) were recruited between May 2012 and December 2014. Demographic and clinical characteristics, Spielberger State‐Trait Anxiety Inventory, Beck Depression Inventory‐

scale, and 18‐month follow‐up outcomes were recorded during the hospital stay. There were significant differences in age, sex, comorbidities, laboratory biomarkers, discharge medications, and unhealthy behaviors, which supported the contention that
HF
r
EF
and
HF
p
EF
represent 2 distinct phenotypes, although there were no significant differences in anxiety and 18‐month outcomes. Multiple logistic regression yielded no significant associations between anxiety and 18‐month outcomes in
HF
r
EF
. By contrast, trait anxiety could predict 18‐month all‐cause mortality (odds ratio, 1.429; 95% CI, 1.020–2.000;
P
=0.038), all‐cause readmission or death (odds ratio, 1.147; 95%
CI
, 1.036–1.271;
P
=0.008), and cardiac readmission or death (odds ratio, 1.133; 95%
CI
, 1.031–1.245;
P
=0.010) in
HF
p
EF
after adjusting for possible confounders.

Conclusions

Trait anxiety was independently associated with 18‐month all‐cause mortality, all‐cause readmission or death, and cardiac readmission or death in

Published: June 2019

Background and Purpose—

The impact of a mobile stroke unit (MSU) on access to intraarterial thrombectomy (IAT) is a prespecified BEST-MSU substudy (Benefits of Stroke Treatment Delivered Using a Mobile Stroke Unit Compared to Standard Management by Emergency Medical Services). On the MSU, IAT decision-making steps, such as computed tomography, neurological exam, and tPA (tissue-type plasminogen activator) treatment are completed before emergency department arrival. We hypothesized that such pre-ED assessment of potential IAT patients on an MSU improves the time from ED arrival to skin puncture time (door-to-puncture-time, DTPT).

Methods—

BEST-MSU is a prospective comparative effectiveness study of MSU versus standard management by emergency medical services (EMS). We compared ED DTPT among the following groups of MSU and EMS patients: all IAT patients, IAT patients post-tPA, and IAT patients post-tPA meeting thrombolytic adjudication criteria over the first 4 years of the study.

Results—

From August 2014 to July 2018, a total of 161 patients underwent IAT. Ninety-four patients presented to the ED via the MSU and 67 by EMS. One hundred forty patients received tPA before IAT, 85 in the MSU arm, and 55 in the EMS arm. One hundred twenty-six patients received tPA within thrombolytic adjudication criteria: 76 MSU and 50 EMS. DTPT in minutes was shorter for MSU patients (all IAT MSU versus EMS 89 versus 99,
P
=0.01; IAT post-tPA MSU versus EMS 93 versus 100,
P
=0.03; and IAT post-tPA within adjudicated criteria MSU versus EMS 93 versus 99.5,
P
=0.03). From 2014 to 2018, DTPT decreased at a faster rate for EMS compared with MSU-managed patients, improving by about an hour.

Conclusions—

Pre-ED IAT evaluation on an MSU results in faster DTPT compared with arrival by EMS. Since 2014, dramatic improvement in ED IAT metrics has attenuated this difference. However, DTPT in all groups indicates substantial room for improvement.

Published: June 2019

Introduction: The aim of the study was to evaluate the analytical performance of the new colorimetric, automatic analyser, Seal AutoAnalyzer 3 High Resolution (Seal AA3 HR) (Seal Analytical, Wisconsin, USA) for urinary iodine measurement. Materials and methods: This study included testing of several analytical features of the method involving: imprecision (within-run %CVr, between- run %CVb and total laboratory precision %CVl), measurement uncertainty, carryover, linearity and method comparison, with 70 urine samples including the measuring range (20 - 700 μg/L). Results: Within-run, %CVb and %CVl of two control levels were 2.03% and 3.04%, 0.51% and 2.61%, and 2.09% and 4.01%, respectively. Carryover effect was less than 1%. The linearity was good in the range of urinary iodine values between 60 and 500 μg/L (R2 = 0.99). Good agreement of urinary iodine values was found between manual technique and Seal AA3 HR, using Passing-Bablok regression (y = 7.84 (- 3.00 to 15.29) + 0.95 (0.90 to 1.00) x) and Blant-Altman test. Cusum test for linearity indicates that there is no significant deviation from linearity (P > 0.1). Conclusions: The obtained results proved excellent precision, reproducibility and linearity, comparable to the already used, manual method. The New Seal AA3 HR automatic analyser is acceptable for urinary iodine measurement with very good analytical characteristics and can be used for urinary iodine epidemiological studies of the Croatian population.
Commodity Price Cycles, the Agricultural Trap, and Thailand's Incessant Subsidies
Authors: Nidhiprabha Bhanupong
Published: June 2019

During Thailand's economic development, the shares of output and employment in agriculture have been consistently higher than in other countries at the same level of income. There are push and pull factors for labor transformation. This paper demonstrates that the slow transformation from rural to urban economy is the result of the agricultural trap, which keeps agrarian labor inside the farm sector. In addition to the lack of public investment in human capital, extremely wasteful farm subsidies have weakened the natural process of structural transformation. Farm subsidies encourage land expansion, which usually lags behind commodity booms, resulting in the excess supply of farm products. In turn, when commodity prices collapse, excess supply perpetuates further subsidies and emboldens the pork barrel activities of incumbent governments.
A Model of Household Savings and Alternative Investments in Rural China
Authors: Cheng Yuekai , Li Hongyi , Sun Qi , Wang Yu
Published: June 2019

This paper explores the relationship between monetary policy, prices, and rural household savings and investment behavior in China. We first develop a two-period life-cycle model with bequests for China's rural economy to analyze the impacts of interest rates, agricultural product prices, and housing prices on rural households’ capital allocation choices (households’ savings deposits, investment in private housing, and investment in agricultural productive fixed assets). We then empirically estimate the theoretical model equations with a newly compiled panel dataset covering the rural areas of 26 provinces from 2001 to 2016. Our empirical results suggest that high housing prices are harmful to the rural economy as they reduce productive investment and consumption. An efficient interest rate market and land tenure system reform are recommended.
Contiguity Theory and Pied-Piping
Authors: Richards Norvin
Published: June 2019

In this article, I apply the conditions of Contiguity Theory ( Richards 2016 ) to the problem of pied-piping. I derive the conditions on pied-piping discovered by Cable ( 2007 , 2010a , b ) and account for the connection discovered by Uribe-Etxebarria (2002) between the conditions on wh-in-situ in a given language and the conditions on pied-piping in that language. In the end, as in Cable’s approach, pied-piping dissolves as a phenomenon; the same conditions that determine when overt movement must take place also determine how much material may be pied-piped.
The tadpole of Physalaemus henselii (Peters) (Anura: Leiuperidae)
Authors: KOLENC FRANCISCO , BORTEIRO CLAUDIO , TEDROS MARCELO , NÚÑEZ DIEGO , MANEYRO RAÚL
Published: June 2019

Although Physalaemus frogs are prominent members of Neotropical herpetofauna, larval stages are not known from more than half of the species in this genus. Herein, we describe the tadpole of Physalaemus henselii based on samples collected in Departamento de Rivera, northern Uruguay. General aspect and major external morphological features are similar to most of other known tadpoles of Physalaemus. Remarkable character states are a medial vent tube and the presence of dorsal and ventral gaps in the row of marginal oral papillae. Physalaemus henselii has been successively assigned to the P. cuvieri and to the P. henselii species groups, but no conclusions can be drawn in support of these associations from external larval morphology. Instead, we found that some character states may contribute to relate species, like the presence of a ventral gap in the marginal row of oral papillae which is shared by P. albonotatus, P. cuqui, P. cuvieri, P. fernandezae and P. henselii. This character state is unique among non-bufonid anurans, although it is also present in some species of the related genus Pseudopaludicola. In addition, P. albonotatus, P. cuqui and P. cuvieri tadpoles can be differentiated from P. fernandezae and P. henselii by the presence of two small ventrolateral gaps, which are absent in the latter.

Gollumjapyx smeagol gen. n., sp. n., an enigmatic hypogean japygid (Diplura: Japygidae) from the eastern Iberian Peninsula
Authors: SENDRA ALBERTO , ORTUÑO VICENTE M. , MORENO AGUSTÍN , MONTAGUD SERGIO , TERUEL SANTIAGO
Published: June 2019

A new species of subterranean japygid dipluran belonging to a new genus is diagnosed and described from the eastern Iberian Peninsula. The new species is highly adapted to hypogean life with very obvious troglobiomorphic features: unpigmented cuticle, an extraordinary lengthening of thorax and appendixes, multiplication of antennomeres and supernumerary placoid sensilla, not just in the apical antennomere but also in the preceding antennomeres. These traits make it the most exceptional of all the hypogean Japygidae known to date, with troglobiomorphic characteristics more accentuated than in other hypogean taxa known in the rest of the world. The cercal armature of the Burmjapyx type (Silvestri, 1930; sensu Paclt, 1957) together with the characteristics of the glandular organs of the first urosternite set it apart from the known Japygidae. However, those characteristics prove insufficient to establish a relation with other genera. It is therefore the only manifestly hypogean japygid species in the Iberian Peninsula, where only Metajapyx moroderi Silvestri, was known in certain caves of the eastern reaches of the Prebetic range. The new species has been located inside six average-sized underground caves, generally in the deepest areas, and may be one of the major hypogean predators in the Iberian Peninsula, with a diet that ranges from Acari to Anillini carabids. Its distribution along the limestone regions of the coastal ranges in the east of the Peninsula coincides with that of paleo-endemic troglobites. Therefore, it is possible to infer a remote origin for this species, as suggested by its high level of specialization in the subterranean ecosystems.
Taxonomic revision of Mycolybas Crotch, 1876 (Coleoptera: Erotylidae)
Authors: LOPES PETERSON L.
Published: June 2019

A taxonomic revision of Mycolybas Crotch, 1876 is proposed. Historically the genus comprised seven species: M. coccineipennis (Motschulsky, 1858), M. cruentatus (Kirsch, 1865), M. egae Crotch, 1876, M. lucidus (Lacordaire, 1842), M. melanocorynus (Lacordaire, 1842), M. rufipennis Guérin, 1956 and M. sanguinosus (Motschulsky, 1858), recorded from Central and South America. After a morphological analysis, new diagnostic characters were discovered (i.e. armed laciniae for M. coccineipennis, and tarsal sexual dimorphism for M. lucidus and two new species). Three species are regarded as synonymies of M. lucidus (M. cruentatus syn. nov., M. egae syn. nov., M. melanocorynus syn. nov.), four are redescribed (M. coccineipennis, M. lucidus, M. rufipennis and

Two new species of eelpouts (Teleostei, Zoarcidae) of the genus Seleniolycus from the Ross Dependency, Antarctica
Authors: MØLLER PETER R. , STEWART ANDREW L.
Published: June 2019

Detailed examination of eelpouts (Zoarcidae) in recently collected material from the Ross Dependency, Antarctica, and held by the Museum of New Zealand Te Papa Tongarewa, revealed two undescribed species of Seleniolycus Anderson, 1988. They both differ from the type species Seleniolycus laevifasciatus (Torno, Tomo & Marschoff, 1977) from the Scotia Sea, Banzarre Bank and Falkland Rise, by having scales on the posterior part of the body (vs. naked), more numerous anal fin rays (69–73 and 64–66 vs. 53–58), total vertebrae (88–97 and 86–89 vs. 74–80), and suborbital head pores (6 and 6–7 vs. 5). Seleniolycus robertsi sp. nov. and S. pectoralis sp. nov. can readily be separated from each other by pectoral fin length (7.9–9.4 vs. 11.1–11.5% SL) and shape (fin entire vs. lower rays exserted), as well as several meristic and morphometric characters. Seleniolycus robertsi inhabits slightly shallower depths than S. pectoralis (1455–2290 vs. 1948–2594 m). The new species have several more generalised character states than Seleniolycus laevifasciatus, and seem to represent the basal-most branch in the Seleniolycus-Melanostigma lineage. A key to the known species of Seleniolycus is provided.

A taxonomic revision of the southwestern Pacific subgenus Hebridosimulium (Diptera: Simuliidae: Simulium)
Authors: CRAIG DOUGLAS A. , CURRIE DOUGLAS C. , HUNTER FIONA F. , SPIRONELLO MIKE
Published: June 2019

Sixteen species, of which 13 are new, in the subgenus Hebridosimulium Grenier & Rageau are now known. Fiji has only Simulium laciniatum, which is widely distributed on five islands. Tahiti has only one species, the enigmatic S. anatolicum. The remaining species are in Vanuatu and known from nine islands, ranging the full length and breadth of the archipelago. Hebridosimulium species are divided among two species groups. The callipygium species group is characterized, in part, by a smooth posterior abdomen in the larvae, and all but one species possess dorsal tubercles on the larval abdomen. Simulium callipygium is the type species, with the tuberculate species in a subgroup comprised of S. banksi, S. johnfrumi, S. pankumuense, and S. tuberculum. The second species group has larvae with the posteroventral abdomen markedly expanded, and all species lack dorsal tubercles. Constituents of the steatopygium species group are S. anatolicum, S. jolyi, S. laciniatum, S. lucyae, S. paradisium, S. steatopygium, S. subparadisium, S. supercilium, and S. undulatum. Two other species of this group, S. adsonense and S. spiroi, of which larvae have markedly pigmented heads, are assigned to the adsonense species subgroup. A chromosome map for Hebridosimulium is established for the first time.
First record of Sphaerodoridae (Phyllodocida: Annelida) from hydrothermal vents
Authors: AGUADO M. T. , ROUSE GREG W.
Published: June 2019

Sphaerodoropsis anae n. sp. is described from sediments near active hydrothermal vents along the northern part of the Pacific Antarctic ridge, adjacent to the Easter Microplate. Two distinct features principally characterize Sphaerodoropsis anae n. sp., the presence of a well-developed proventricle, quite similar to the proventricle found in Syllidae, and bi-dentate compound chaetae with spinulation. It is also characterized by the presence of four macrotubercles per transverse row, with the lateral ones pear-shaped and the median macrotubercles spherical and smaller. Types of other Sphaerodoropsis species were examined and Sphaerodoropsis biserialis (Berkeley & Berkeley, 1944) also has compound chaetae with spinulation. This feature was not previously described in this species. Some comments about the current systematics of Sphaerodoropsis and Sphaerodoridae are made, as well as a discussion of the proventricle.
Three new species of Lebbeus (Crustacea: Decapoda: Hippolytidae) from the Northeastern Pacific
Authors: JENSEN GREGORY C.
Published: June 2019

Three new species of hippolytid shrimps are described from the northeastern Pacific. Lebbeus eludus and L. mundus are often found at shallow depths (10–20 m) in the crevices of rock walls. Both have previously been mistaken for a western Pacific species, L. schrencki (Brashnikov) and are characterized by having an unusual, deep, transverse groove on the dorsal surface of the second abdominal somite, short rostrums, and epipods on the first three pereopods. The third shrimp, L. acudactylus, has been found at depths of 150–170 m and appears closely related to L. grandimanus (Brashnikov) and L. balsii Hayashi, but lacks a comb of spines on the mesial margin of the third maxillipeds that is characteristic of those two species. Color photos showing the unique patterns of all three new species are provided.

The making of a mega-journal in taxonomy
Authors: ZHANG ZHI-QIANG
Published: June 2019

We live in an era of elevated rates of extinction, yet about 90% of the Earth’s species of animals, plants and micro-organisms remain undescribed (Wilson, 2004). Although there are many journals that may publish taxonomic papers, it is increasingly difficult to publish papers on descriptive taxonomy in a timely and cost-effective manner. It is common for a taxonomist to wait for eight to ten months and sometimes years to get a paper published. And unless there is access to an institutional monograph series, it is even more difficult to publish a large taxonomic revision or monograph, not only because of costs, but the fact that most journals are of a fixed size and have limits on the length of papers. This impediment in publishing has a huge negative impact on taxonomy—the delay and difficulty in getting works published can discourage taxonomists who worked for years and unpublished works are a huge waste of talent and resources (often publicly funded). Large monographs are particularly important to the study of complex species-rich taxa, as taxonomy is about comparison, and closely related species must be compared together. Much needed is a rapid and efficient journal for descriptive papers and monographs in taxonomy. Published concurrently in print and online, Zootaxa was established as a rapid journal at the start of this century to remove these impediments in taxonomy. It has received overwhelming support from zoological taxonomists around the world, despite the fact that this diverse group of specialists are often perceived as too individualistic and fragmented into diverse subdisciplines to come together as a community. Zootaxa rapidly transformed itself from a small journal publishing 20 papers totalling 302 pages on 15 occasions in 2001 to a mega-journal publishing 1,020 papers in 22,052 pages as frequently as twice each week in 2006 (Fig. 1)—a pattern of rapid growth that is unprecedented for any scholarly journal, in both the sciences and humanities. This is indeed a very promising sign for the rejuvenation of zoological branch of one of world’s oldest science (that of naming and describing nature) in a new era when its services are most needed.

Caudacalanus (Copepoda, Calanoida): a new benthopelagic genus from the abyssof the tropical South Atlantic and Southern Ocean
Authors: MARKHASEVA ELENA L. , SCHULZ KNUD
Published: June 2019

Two species of a new spinocalanoidean genus, Caudacalanus, are described from female specimens collected during the German expeditions ANDEEP I–II in 2002 and DIVA-1 in 2000 at abyssal depths above the seabed in the Southern Ocean and tropical waters of the South Atlantic. Segmentation and setation of swimming legs of the new genus are typical of the superfamily Spinocalanoidea. Caudacalanus gen. nov. shares the derived morphology of the oral parts and P1 basis and endopod with a monophyletic group of genera, viz. Arctokonstantinus, Foxtonia and Sognocalanus. Arctokonstantinidae is available for this lineage. The new genus differs from other spinocalanoideans by strong asymmetry of the caudal rami, with the right ramus nearly twice as long and wide as the left; setation of maxillule exopod reduced to 0–1 seta; maxilla basis lacking any setae; and maxilliped basis with 1 seta and endopod reduced to 3 segments.

Published: June 2019

Both male and female of the new deep-sea species Smacigastes barti sp. nov. (Tegastidae, Sars) are described in detail. Copepoda is one of the most diversified taxa at deep-sea hydrothermal vents, but only one species of the family Tegastidae has been described from this habitat and other deep-sea environments. Smacigastes barti is the second species of the genus Smacigastes Ivanenko & Defaye, 2004, and was found in artificial substrates deployed in the vicinity of and 0.5 m from tubeworm aggregations at the 9°50´N region on the East Pacific Rise at 2500 meters depth. The derived character states of the new species are the lack of coxal endites on the maxilla, and 2-segmented exopods of swimming legs 2 and 3, the latter being the result of the fusion of the 2 proximal segments. An identification key to all known genera of Tegastidae is provided. Interestingly, the distribution of S. barti showed that it does not tolerate elevated temperatures and/or the presence of hydrogen sulfide or oxygen fluctuations, although both species of this genus were found in deepsea chemosynthetic environments.
First record of the genus Pseudomesochra T. Scott (Harpacticoida: Pseudotachidiidae)in the South Atlantic with description of a deep-sea species: Pseudomesochralongiseta sp. nov.
Authors: VASCONCELOS DANIELLE MENOR , GEORGE KAI HORST , PARREIRA DOS SANTOS PAULO JORGE
Published: June 2019

Samples collected during the Sergipe Continental Slope Environmental Characterization Project coordinated by PETROBRAS (The Brazilian Petroleum Company) revealed a new species of the family Pseudotachidiidae Lang, 1936 (Copepoda, Harpacticoida), Pseudomesochra longiseta sp. nov. This is the first record of the genus Pseudomesochra T. Scott, 1902 for the South Atlantic. Pseudomesochra longiseta sp. nov. can be distinguished from all species of the genus Pseudomesochra by the presence of four sensilla on the rostrum and a very long terminal “rat-tail” seta on the second segment of the antenna. It shares with P. tamara Smirnov, 1946 the addition of one inner seta on the first exopodal segment of the swimming legs 2–4 (P2–P4), a character absent in the remaining species of the genus. Pseudomesochra longiseta sp. nov. is the fourth species described within this genus with 2-segmented P2–P4 endopods. The inclusion of the new species in Pseudomesochra requires the modification of some autapomorphic characters of the genus, the most important being the presence of four sensilla on the rostrum, a character shared with other Pseudotachidiidae.
New species of Bairdioidea (Crustacea, Ostracoda) from the Southern Ocean anddiscussions on Bairdoppilata simplex (Brady, 1880), ?Bairdoppilata labiata(Müller, 1908) and Bythopussella aculeata (Müller, 1908)
Authors: BRANDÃO SIMONE N.
Published: June 2019

Only a few bairdioid species were reported from the high Antarctic region of the Southern Ocean. One of these species is the supposedly widely distributed Bairdoppilata simplex (Brady, 1880). The re-study of material previously identified as Bairdoppilata simplex (Brady, 1880) indicates that these specimens should be assigned to several different species. On the basis of the specimens studied herein and of published illustrations it is possible to conclude that more than ten species are represented in the material that has been misidentified under this name, seven of these species were re-studied and are illustrated herein. One of them, Bairdoppilata labiata (Müller, 1908), previously considered a junior synonym of B. simplex, is herein considered a valid taxon and its lectotype is designated. Additionally, in the present publication 82 bairdioid live specimens and 585 valves collected from depths of 1123 to 4932m during the ANDEEP Project in the Atlantic Sector of the Southern Ocean were studied. Seven new species are described—?Neonesidea keyseri sp. nov., Bythocypris praerenis sp. nov., Bythocypris malyutinae sp. nov., Bythocypris polarsterni sp. nov., Bythocypris richarddinglei sp. nov., Bythocypris weddellensis sp. nov., Bythopussella brandtae sp. nov. A new combination is suggested to the bathyal species Bythopussella microguttata (Whatley et al., 1998b) n. comb. (previously described in the genus Bairdoppilata). Statistical analyses (MDS, ANOSIM, BEST_BIOENV, and Cluster) show clear relationships among the bairdioid assemblages and the depth and geographical locality where samples were collected.
First record and new species of the genus Hebefustis Siebenaller & Hessler, 1977(Isopoda: Asellota: Nannoniscidae) from the deep Weddell Sea Basin
Authors: KAISER STEFANIE
Published: June 2019

The ANDEEP (ANtarctic benthic DEEP-sea biodiversity, colonisation history and recent community patterns) cruises contributed immensely to the understanding of the deep Southern Ocean biodiversity, and study of the fauna, in particular the isopod crustaceans, which were revealed to be patchily rich. Most of the species found during the three ANDEEP expeditions were not only new to the region but also new to science. In the current paper a new nannoniscid species, Hebefustis clareolithis sp. nov., is described from the deep Weddell Sea Basin (Southern Ocean). Specimens of the new species were sampled during ANDEEP III in Antarctic summer 2004/05 and represent the first Southern Ocean record of the genus Hebefustis Siebenaller & Hessler, 1977. The new species closely resembles Hebefustis cornutus Siebenaller & Hessler, 1977 but can be distinguished from the latter by the number of flagellar articles of the female antenna, the shape of pleopod 1 and pleotelson in male. A key to the species in the genus Hebefustis is provided.
Results of the DIVA-1 Expedition of RV “Meteor” (Cruise M48:1):Three new species of Munnopsidae Sars, 1864 from abyssal depths of the AngolaBasin (Crustacea: Isopoda: Asellota)
Authors: MURSCH ANDRE , BRENKE NILS , WÄGELE JOHANN WOLFGANG
Published: June 2019

Three new species of Munnopsidae, Eurycope monodon sp. nov., E. denticollis sp. nov. and Munneurycope Persephone sp. nov. are described from the deep sea of the Angola Basin in the southeast Atlantic. E. monodon and E. denticollis closely resemble E. glabra Kensley, 1978 in general appearance and in the peculiar shape of the female operculum with an apex shifted far frontally, but with a less pronounced medial lobe of antenna 1 article 1, presence of dorsal tubercles on the pleotelson and uropods with less reduced exopods. Eurycope monodon has a rostrum bearing a single anteromedian spinelike seta and a male pleopod 1 with a subapical, hook-like cusp of the distolateral lobe curved anteriolaterally. Eurycope denticollis has paired and relatively shorter spine-like setae on the rostrum, and the cusp of pleopod 1 distolateral lobe is curved caudolaterally. M. persephone is the first species of the genus recorded from the South Atlantic. It differs from the most similar species, M. nodifrons (Hansen, 1916), in antenna 1 with elongated third article, a maxilliped with more distinctly truncate endite, and a different dentation on the retinacula.
Microcope gen. nov.—a new deep-sea genus of Munnopsidae (Crustacea, Isopoda,Asellota), with description of two new species from the Southern Hemisphere
Authors: MALYUTINA MARINA V.
Published: June 2019

A new genus of Munnopsidae Lilljeborg, Microcope gen. nov., is described including Eurycope ovata Birstein, 1970 from the northwestern Pacific, and two new species, collected in the Cape Basin, and Atlantic Sector of the Southern Ocean. The new genus combines characters common for some genera of Eurycopinae Hansen and Betamorphinae Kussakin, but cannot be related to any known genus of the existing subfamilies and, thus, still remains incertae sedis. Microcope gen. nov. is characterized by minute eurycopine-like broad oval body with fused pereonites 5–7 on the one hand, and betamorpha-like face, pereopods 2–4 and uropods, with extended distomedial projection of the protopod on the other hand. The following combination of characters distinguishes the new genus: short head hidden under the anterior flange of pereonite 1, absence of rostrum, slender male pleopods 2, flattened female pleopod 2, and distinct shape and armament of pereopods 5–7 and pleopod 3. The descriptions of Microcope gen. nov., as well as the two new species, M. denticulate sp. nov., and M. levissima sp. nov., are presented.
Revision of the genus Pozziella (Porifera: Poecilosclerida) with description ofthree new species from the eastern Pacific
Authors: DÍAZ-AGRAS GUILLERMO
Published: June 2019

To date, the poecilosclerid sponge genus Pozziella Topsent, 1896 was represented by two species: Pozziella clavisepta Topsent, 1896 and Pozziella aperta (Topsent, 1920), which are presently redescribed. During the campaign SO 144-3a of the project PAGANINI in the Pacific Ocean between the Galapagos Archipelago and Central America, three new species were recovered and are described here: Pozziella cerilla sp. nov., Pozziella neuhausi sp. nov. and Pozziella lueteri sp. nov. The present study led to a revision of the genus and an attempt to resolve the relationships between the species, based on the likeness of spicule complements and biometric characters. A similarity analysis revealed that Atlantic and Pacific species clustered separately. In addition, a key to all species of the genus based on spicular characters is provided.

Authors: GIL-MANSILLA ESTHER , GARCÍA-ÁLVAREZ ÓSCAR , URGORRI VICTORIANO
Published: June 2019

Solenogastres are a small class of vermiform Mollusca that present a mantle with calcareous sclerites and a ventral pedal groove. During the expedition Me48/1 DIVA 1, carried out in the abyssal Angola Basin between 5100-5500 m depth, several specimens of Solenogastres were collected. Their study has made possible to describe two new species and a new genus of the family Acanthomeniidae Salvini-Plawen, 1978, whose anatomical features have caused the modification of the family definition.

Published: June 2019

Two new species of Glyptothorax are described from the rivers draining the Annam Cordilleras in central Vietnam. Glyptothorax filicatus n. sp. is distinguished from congeners in Indochina in having a diverging pattern of striae running along the edges of the central depression in the thoracic adhesive apparatus, and a combination of the following characters: dorsal spine length 13.7–15.1% SL, pectoral fin length 21.5–21.9% SL, length of adipose-fin base 13.3–15.0% SL, depth of caudal peduncle 8.4–8.8% SL, body depth at anus 15.1–16.0% SL, snout length 48.0–52.9% HL, eye diameter 8.9– 9.9% HL, anterior nuchal plate strongly demarcated in beige and caudal peduncle with a pale vertical band. Glyptothorax strabonis n. sp. is distinguished from congeners in Indochina in having a very small eye (6.2–6.5% HL), and a combination of the following characters: length of caudal peduncle 20.5–21.2% SL, depth of caudal peduncle 7.5–9.2% SL, body depth at anus 13.7–20.9% SL, head width 17.9–18.8% SL, presence of 14–16 serrae on posterior margin of pectoral spine, and coloration consisting of a dark-brown body with indistinct pale mid-lateral and mid-dorsal stripes.
First record of Hexaglandula corynosoma (Travassos, 1915) Petrochenko, 1958 (Acanthocephala: Polymorphidae) in intermediate and definitive hosts in Mexico
Authors: GUILLÉN-HERNÁNDEZ SERGIO , GARCÍA-VARELA MARTÍN , DE LEÓN GERARDO PÉREZ-PONCE
Published: June 2019

Members of Polymorphidae, including Hexaglandula corynosoma, are acanthocephalans commonly found as intestinal parasites in marine mammals, fish-eating birds and waterfowl. Hexaglandula corynosoma is distributed throughout the Southeastern U. S. and southwards to Puerto Rico and Brazil. An acanthocephalan (and its larvae) resembling H. corynosoma were found parasitizing intermediate (decapod crustaceans, Uca spinicarpa) and definitive hosts (yellow-crowned night herons, Nyctanacea violacea) from various localities in Mexico. A morphological and genetic study, in combination with previous studies, confirmed that the larvae and adults were conspecific and corresponded to H. corynosoma. This is the first record of H. corynosoma in Mexico parasitizing intermediate and definitive hosts.
Ompok supernus, a new catfish (Teleostei: Siluridae) from Borneo
Authors: NG HEOK HEE
Published: June 2019

Ompok supernus, a new species of silurid catfish is described from the Rungan River drainage in Kalimantan Tengah, southern Borneo. Ompok supernus can be distinguished from all Southeast Asian congeners, except for O. borneensis, O. fumidus and O. leiacanthus, in having a combination of a brown body without any prominent black humeral spot, the rictal lobes separated by a superficial groove extending from the corner of the mouth to the submandibular groove, a gape not reaching beyond the anterior border of the orbit, and 54–66 anal-fin rays. Ompok supernus differs from O. borneensis, O. fumidus and O. leiacanthus in having more dorsally-placed eyes, manifested in its smaller interorbital distance compared to the latter three species (42.6–48.7% HL vs. 49.1–59.5), and a combination of a mottled body and a rounded anterior profile of the lower jaw.

Complete mitogenome of Psorodonotus venosus (Orthoptera, Tettigoniidae; Tettigoniinae): Short intergenic spacers shorten the total genome
Authors: KARŞI UĞUR , ÇIPLAK BATTAL
Published: June 2019

Mitogenomes are popular sources of data in evolutionary studies. By development of next generation sequencing the number of total mitogenome in data bases rapidly increased. However, there is still a limited number of total mitogenome known from species of Tettigoniinae. This paper aims to describe the total mitogenome of Psorodonotus venosus (Orthoptera, Tettigoniidae; Tettigoniinae) obtained by NGS reads. The total mitogenome is 15836-15845 bp and consists of 13 protein coding genes (PCG), 22 tRNA genes, two rRNA genes and an AT rich control region as in other metazozans. The mitogenome is AT skewed with 69.5% AT percentage. The genes are ordered as in pancrustacean. Total length of PCGs is 11229 bp, the start codon for all fits ATN pattern and stop codons are incomplete T-- / TA- and rarely complete TAA. Total length of 22 tRNA genes is 1447 bp and their anticodons are identical to other members of Tettigonioidea. The mitogenome contains 12 overlapping regions constituting 41 bp in total. Of these 12 overlapping regions those between trnW-trnC, atp6-atp8, nad4-nad4L, nad6 –cytb and atp6-cox3 gene pairs seem to be conserved. The total length of seven noncoding intergenic spacers is 46 bp. We concluded that P. venosus is one of the species with short mitogenome amongst Tettigonioidea because of limited number and length of noncoding intergenic spacers.
Eggs sunny-side up: A new species of Olea, an unusual oophagous sea slug (Gastropoda: Heterobranchia: Sacoglossa), from the western Atlantic
Authors: FILHO HILTON GALVÃO , PAULAY GUSTAV , KRUG PATRICK J.
Published: June 2019

Nearly all of the recognized species of sea slugs in clade Sacoglossa (about 300 taxa) are herbivorous, using a uniseriate radula in suctorial feeding. The only exceptions are a pair of monotypic genera in the ceratiform family Limapontiidae: Olea Agersborg, 1923 from the northeastern Pacific, and Calliopaea d’Orbigny, 1837 from the northeastern Atlantic coast of Europe and the Mediterranean. Both genera feed on the eggs of other heterobranchs, notably cephalaspideans, and lack cerata on the anterior dorsum. Major differences are that C. bellula d’Orbigny, 1837 has more cerata than O. hansineensis Agersborg, 1923, a more typical radula with ascending and descending rows of fully-formed teeth, and a much longer penial stylet. Here, we describe a new egg-eating sacoglossan species from the subtropical Gulf of Mexico coast of Florida, U.S.A. Phylogenetic relationships inferred from analyses of a four-gene dataset including 219 sacoglossan species indicated the new taxon (O. hensoni n. sp.) belongs to Olea. The generic placement of the new species is also supported by its highly reduced radula and comparatively short penial stylet. A full description of the reproductive, digestive, and nervous systems is also provided. Finding a new Olea species in the warm waters of the western Atlantic was surprising, given the genus was previously known only from the cold northern Pacific, and suggests further diversity in oophagous sacoglossans may await discovery.
