Objectives: We aimed to examine the relations of very high levels of serum uric acid (sUA) with features of culprit lesion plaque morphology determined by optical coherence tomography (OCT) and adverse clinical outcomes in patients with acute coronary syndrome (ACS). Methods: We retrospectively compared ACS patients according to sUA levels of > 8.0 mg/dL (n = 169), 7.1–8.0 mg/dL (n = 163), 6.1–7.0 mg/dL (n = 259), and ≤6.0 mg/dL (n = 717). Angiography and OCT findings were analyzed in patients with preintervention OCT and the 4 sUA groups (> 8.0 mg/dL, n = 61; 7.1–8.0 mg/dL, n = 72; 6.1–7.0 mg/dL, n = 131; and ≤6.0 mg/dL, n = 348) were compared. Results: Cardiogenic shock was more prevalent in ACS patients with sUA > 8.0 mg/dL (22% vs. 19% vs. 10% vs. 6%, p < 0.001). Plaque rupture was observed more prevalently by OCT in patients with sUA > 8.0 mg/dL (67% vs. 47% vs. 56% vs. 45%, p = 0.027). At the 2-year follow-up, Kaplan-Meier estimates showed higher cardiac mortality in patients with sUA > 8.0 mg/dL (25% vs. 12% vs. 5% vs. 5%, p < 0.001). After adjusting for traditional cardiovascular risk factors and creatinine levels, patients with sUA > 8.0 mg/dL showed a 4.5-fold increased risk in 2-year cardiac death by multivariate Cox proportional hazard analysis (hazard ratio 4.54, 95% confidence interval 2.98–6.91; p < 0.001). Conclusions: Very high sUA levels like > 8.0 mg/dL are the primary predictor of 2-year cardiac mortality and could partly be caused by adverse effects of accumulated sUA on plaque morphology in patients with ACS.

Published: February 2019

Background: Treatment of atopic dermatitis (AD) may be challenging, therefore some patients seek complementary and alternative medications (CAM). We determined prevalence and predictors for CAM use in a hospital cohort of AD patients. Material and Methods: Between January 1, 2012, and December 31, 2017, AD patients referred to the dermatological outpatient clinic at Bispebjerg Hospital were included in the study. Information on CAM use, demographics and disease characteristics were obtained by questionnaire, and associations were determined by χ2 and t test separately for children (< 16 years) and adults (≥16 years). Results: In total 441 filled in the questionnaire on AD, and 433 patients responded to the questions about CAM use: 198 children and 235 adults. A total of 137 (31.6%) had used one or more CAM. CAM use in children was significantly associated with prior use of ≥2 conventional treatments (p = 0.047) and topical calcineurin inhibitors (p = 0.021), a higher number of affected eczema sites (p < 0.001) including more frequent affection of the face and extremities, a higher SCORAD score (p = 0.045), and low mean overall self-rated health (p = 0.003). CAM use in adults was significantly associated with lower age of onset of AD (p = 0.004), comorbid allergic rhinoconjunctivitis (p = 0.039), frequent use of moisturizing cream (p = 0.024), facial and neck eczema (p = 0.005) and high educational level (p = 0.043). Conclusion: CAM use is frequent in both children and adult AD patients. CAM users are characterized by long disease duration, a significant disease burden and by having a longer education. The high prevalence of CAM may indicate that patients’ expectations regarding treatment of AD are not redeemed in the conventional health care system.

Published: February 2019

Osteoarthritic pain has a strong impact on patients’ quality of life. Understanding the pathogenic mechanisms underlying osteoarthritic pain will likely lead to the development of more effective treatments. In the present study of osteoarthritic model rats, we observed a reduction of M-current density and a remarkable decrease in the levels of KCNQ2 and KCNQ3 proteins and mRNAs in dorsal root ganglia (DRG) neurons, which were associated with hyperalgesic behaviors. The activation of KCNQ/M channels with flupirtine significantly increased the mechanical threshold and prolonged the withdrawal latency of osteoarthritic model rats at 3–14 days after model induction, and all effects of flupirtine were blocked by KCNQ/M-channel antagonist, XE-991. Together, these results indicate that suppression of KCNQ/M channels in primary DRG neurons plays a crucial role in the development of osteoarthritic pain.

Published: February 2019

Background/Aims: The current diagnostic workup of Cushing’s syndrome (CS) requires various tests which only capture short-term cortisol exposure, whereas patients with endogenous CS generally have elevated cortisol levels over longer periods of time. Scalp hair assessment has emerged as a convenient test in capturing glucocorticoid concentrations over long periods of time. The aim of this multicenter, multinational, prospective, case-control study was to evaluate the diagnostic efficacy of scalp hair glucocorticoids in screening of endogenous CS. Methods: We assessed the diagnostic performances of hair cortisol (HairF), hair cortisone (HairE), and the sum of both (sumHairF+E), as measured by a state-of-the-art LC-MS/MS technique, in untreated patients with confirmed endogenous CS (n = 89) as well as in community controls (n = 295) from the population-based Lifelines cohort study. Results: Both glucocorticoids were significantly elevated in CS patients when compared to controls. A high diagnostic efficacy was found for HairF (area under the curve 0.87 [95% CI: 0.83–0.92]), HairE (0.93 [0.89–0.96]), and sumHairF+E (0.92 [0.88–0.96]) (all p < 0.001). The participants were accurately classified at the optimal cutoff threshold in 86% of the cases (81% sensitivity, 88% specificity, and 94% negative predictive value [NPV]) by HairF, in 90% of the cases (87% sensitivity, 90% specificity, and 96% NPV) by HairE, and in 87% of the cases (86% sensitivity, 88% specificity, and 95% NPV) by the sumHairF+E. HairE was shown to be the most accurate in differentiating CS patients from controls. Conclusion: Scalp hair glucocorticoids, especially hair cortisone, can be seen as a promising biomarker in screening for CS. Its convenience in collection and workup additionally makes it feasible for first-line screening.
Enterovirus Persistence in Cardiac Cells of Patients With Idiopathic Dilated Cardiomyopathy Is Linked to 5’ Terminal Genomic RNA-Deleted Viral Populations With Viral-Encoded Proteinase Activities

Published: February 2019

Background:

Group B enteroviruses are common causes of acute myocarditis, which can be a precursor of chronic myocarditis and dilated cardiomyopathy, leading causes of heart transplantation. To date, the specific viral functions involved in the development of dilated cardiomyopathy remain unclear.

Methods:

Total RNA from cardiac tissue of patients with dilated cardiomyopathy was extracted, and sequences corresponding to the 5’ termini of enterovirus RNAs were identified. After next-generation RNA sequencing, viral cDNA clones mimicking the enterovirus RNA sequences found in patient tissues were generated in vitro, and their replication and impact on host cell functions were assessed on primary human cardiac cells in culture.

Results:

Major enterovirus B populations characterized by 5’ terminal genomic RNA deletions ranging from 17 to 50 nucleotides were identified either alone or associated with low proportions of intact 5’ genomic termini. In situ hybridization and immunohistological assays detected these persistent genomes in clusters of cardiomyocytes. Transfection of viral RNA into primary human cardiomyocytes demonstrated that deleted forms of genomic RNAs displayed early replication activities in the absence of detectable viral plaque formation, whereas mixed deleted and complete forms generated particles capable of inducing cytopathic effects at levels distinct from those observed with full-length forms alone. Moreover, deleted or full-length and mixed forms of viral RNA were capable of directing translation and production of proteolytically active viral proteinase 2A in human cardiomyocytes.

Conclusions:

We demonstrate that persistent viral forms are composed of B-type enteroviruses harboring a 5’ terminal deletion in their genomic RNAs and that these viruses alone or associated with full-length populations of helper RNAs could impair cardiomyocyte functions by the proteolytic activity of viral proteinase 2A in cases of unexplained dilated cardiomyopathy. These results provide a better understanding of the molecular mechanisms that underlie the persistence of EV forms in human cardiac tissues and should stimulate the development of new therapeutic strategies based on specific inhibitors of the coxsackievirus B proteinase 2A activity for acute and chronic cardiac infections.
Cardiac Sympathetic Denervation Suppresses Atrial Fibrillation and Blood Pressure in a Chronic Intermittent Hypoxia Rat Model of Obstructive Sleep Apnea
Authors: Yang Xuechao , Zhang Linfei , Liu Huan , Shao Yongfeng , Zhang Shijiang
Published: February 2019

Background

Chronic intermittent hypoxia (
CIH
) is a distinct pathological mechanism of obstructive sleep apnea (
OSA
), which is recognized as an independent risk factor for cardiovascular diseases. The aims of this study were to ascertain whether
CIH
induces atrial fibrillation (
AF
), to determine whether cardiac sympathetic denervation (
CSD
) can prevent it and suppress blood pressure, and to explore the potential molecular mechanisms involved.

Methods and Results

Sixty Sprague‐Dawley male rats were randomly divided into 4 groups: sham,
CSD
,
CIH
,
CIH
+
CSD
. The rats were exposed either to
CIH
8 hours daily or normoxia for 6 weeks. Cardiac pathology and structure were analyzed by hematoxylin and eosin staining and echocardiogram. ECG, blood pressure, body weight, and blood gas were recorded. Connexin 43 and tyrosine hydroxylase were detected by western blot, immunohistochemistry, and immunofluorescence.
CIH
induced atrial remodeling, and increased
AF
inducibility.
CSD
treatment reduced postapneic blood pressure rises and
AF
susceptibility, which could attenuate
CIH
‐associated structural atrial arrhythmogenic remodeling. In addition,
CIH
‐induced sympathetic nerve hyperinnervation and
CSD
treatment reduced sympathetic innervation, which may affect
CIH
‐induced
AF
‐associated sympathovagal imbalance. Connexin 43 was specifically downregulated in
CIH
, whereas
CSD
treatment increased its expression.

Conclusions

These results suggested
CIH
induces atrial remodeling, increases
AF
inducibility, results in sympathetic nerve hyperinnervation, and decreases connexin 43 expression, but
CSD
treatment reduces
AF
susceptibility, postapneic blood pressure increase, sympathetic innervation, and the alteration of Cx43, which may be a key point in the genesis of
CIH
‐induced
AF
.

Published: February 2019

Background

The impact of skeletal muscle size, quantified using simple noninvasive images routinely obtained during cardiac magnetic resonance imaging studies on mortality in the heart failure (
HF
) population is currently unknown.

Methods and Results

We prospectively enrolled 567 subjects without
HF
(n=364), with
HF
with reduced ejection fraction (n=111), or with HF with preserved ejection fraction (n=92), who underwent a cardiac magnetic resonance imaging. Skeletal muscle cross‐sectional area was assessed with manual tracing of major thoracic muscle groups on axial chest magnetic resonance images. Factor analysis was used to identify a latent factor underlying the shared variability in thoracic muscle cross‐sectional area. Cox regression was used to assess the relationship between these measurements and all‐cause mortality (median follow up, 36.4 months). A higher overall thoracic muscle area factor assessed with principal component analysis was independently associated with lower mortality (standardized hazard ratio, 0.51;
P
<0.0001). The thoracic muscle area factor was predictive of death in subjects with
HF
with preserved ejection fraction,
HF
with reduced ejection fraction, and those without
HF
. Among all muscle groups, the pectoralis major cross‐sectional area was the most representative of overall muscle area and was also the most robust predictor of death. A higher pectoralis major cross‐sectional area predicted a lower mortality (standardized hazard ratio, 0.49;
P
<0.0001), which persisted after adjustment for various confounders (standardized hazard ratio, 0.55;
P
=0.0017).

Conclusions

Axial muscle size, and in particular smaller size of the pectoralis major, is independently associated with higher risk of mortality in patients with and without
HF
. Further work should clarify the role of muscle wasting as a therapeutic target in patients with
HF
.

Published: February 2019

Background

Posttraumatic stress disorder (
PTSD
) is associated with risk of cardiovascular disease (
CVD
). Biopsychosocial factors associated with
PTSD
likely account for some or all of this association. We determined whether 1, or a combination of comorbid conditions explained the association between
PTSD
and incident
CVD
.

Methods and Results

Eligible patients used 1 of 5 Veterans Health Affairs medical centers distributed across the United States. Data were obtained from electronic health records. At index date, 2519 Veterans Health Affairs (
VA
) patients, 30 to 70 years of age, had
PTSD
diagnoses and 1659 did not. Patients had no
CVD
diagnoses for 12 months before index date. Patients could enter the cohort between 2008 and 2012 with follow‐up until 2015. Age‐adjusted Cox proportional hazard models were computed before and after adjusting for comorbidities. Patients were middle aged (mean=50.1 years,
SD
±11.0), mostly male (87.0%), and 60% were white. The age‐adjusted association between
PTSD
and incident
CVD
was significant (hazard ratio=1.41; 95%
CI
: 1.21–1.63). After adjustment for metabolic conditions, the association between
PTSD
and incident
CVD
was attenuated but remained significant (hazard ratio=1.23; 95%
CI
: 1.06–1.44). After additional adjustment for smoking, sleep disorder, substance use disorder, anxiety disorders, and depression,
PTSD
was not associated with incident
CVD
(hazard ratio=0.96; 95%
CI
: 0.81–1.15).

Conclusions

PTSD
is not an independent risk factor for
CVD
. Physical and psychiatric conditions and smoking that co‐occur with
PTSD
explain why this patient population has an increased risk of
CVD
. Careful monitoring may limit exposure to
CVD
risk factors and subsequent incident
CVD
.

Sample size and cardinal orientation in cambial activity analysis: a case study
Authors: de Souza Arêdes-dos-Reis Maxmira , Costa Monique Silva , dos Santos Gabriel Uriel Cruz Araújo , Callado Cátia Henriques
Published: February 2019

Radial growth dynamics of woody species is studied by different methods. the annual monitoring of cambial activity has been recommended as the method of greatest accuracy in research and appropriate for studies in protected areas for biological conservation, because it is largely nondestructive. Nevertheless, sampling protocols still need more standardization and precision. this study aims to investigate the influence of cardinal orientation on the number of cells in the cambial zone, and to evaluate the number of trees needed to conduct histological studies of cambial activity in Cedrela odorata, a tropical species with well-defined annual growth in the Atlantic Forest of South America/Brazil. Seventeen trees were evaluated during the period of intense cambial activity, with the sampling of four quadrants of the stem, according to cardinal orientation. the variance of cambial cell numbers was calculated for different numbers of trees. the results showed that radial growth variance was not related to cardinal orientation, but that at least 12 trees should be sampled for robust data on cambial dynamics.

Published: February 2019

Mistletoes are hemi-parasitic plants growing on many tree species. They grow on the tree branches or trunk of a tree and form root-like structures called haustoria that penetrate into the tree, taking up water and mineral nutrients. Mistletoe is capable of causing a variety of effects to its hosts, including changes in wood formation and leaf development. We investigate and discuss the effects of pine mistletoe (Viscum album ssp. austriacum, Santalaceae) on branch wood and needle anatomy of Scots pine (Pinus sylvestris, Pinaceae). Parasitized and nonparasitized branches of Scots pine were sampled from host tree crowns of trees growing on the same site. Branches were taken from mid-crown facing south. They were cut at 2 cm proximal and 2 cm distal to the mistletoe on each host branch and at the corresponding position in the case of uninfected branches from the same host. The wood anatomy at proximal and distal parts and the parts at the corresponding position in the non-parasitized section was compared. The anatomy of one-year-old needles from both parasitized and non-parasitized branches was also compared. Mistletoe had significant influences on wood and needle anatomy. The major changes were the decreases in the double wall thickness, lumen area, tangential lumen area and radial lumen area of the tracheids in the wood and a decrease in vascular area in the needles. These results help to understand how mistletoe acts on its host.
CharKey: An electronic identification key for wood charcoals of French Guiana
Authors: Bodin Stéphanie C. , Scheel-Ybert Rita , Beauchêne Jacques , Molino Jean-François , Bremond Laurent
Published: February 2019

Tropical tree floras are highly diverse and many genera and species share similar anatomical patterns, making the identification of tropical wood charcoal very difficult. Appropriate tools to characterize charcoal anatomy are thus needed to facilitate and improve identification in such species-rich areas.

This paper presents the first computer-aided identification key designed for charcoals from French Guiana, based on the wood anatomy of 507 species belonging to 274 genera and 71 families, which covers respectively 28%, 67% and 86% of the tree species, genera and families currently listed in this part of Amazonia. Species of the same genus are recorded together except those described under a synonym genus in Détienne et al. (1982) that were kept separately. As a result, the key contains 289 ‘items’ and mostly aims to identify charcoals at the genus level. It records 26 anatomical features leading to 112 feature states, almost all of which are illustrated by SEM photographs of charcoal. The descriptions were mostly taken from Détienne et al.’s guidebook on tropical woods of French Guiana (1982) and follow the IAWA list of microscopic features for hardwood identification (Wheeler et al. 1989). Some adjustments were made to a few features and those that are unrelated to charcoal identification were excluded. The whole tool, named CharKey, contains the key itself and the associated database including photographs. It can be downloaded on Figshare at https://figshare.com/s/d7d40060b53d2ad60389 (doi: 10.6084/m9.figshare.6396005). CharKey is accessible using the free software Xper2, specifically conceived for taxonomic description and computer aided-identification.
Wood anatomy of seven Stryphnodendron species (Mimosoid clade - Caesalpinioideae - Leguminosae)
Authors: dos Santos Kelly Cristina Moreira , dos Santos Gabriel Uriel Cruz Araújo , Barros Claudia Franca , de Lima Haroldo Cavalcante , Callado Cátia Henriques
Published: February 2019

Stryphnodendron Mart. is a widespread genus in the Neotropics and its species are widely used for their timber, in popular medicine, and for tanning. The similarities in their external morphology make species identification difficult in this genus. This study describes and compares the wood anatomy of the seven species of Stryphnodendron most frequently found in Brazilian forest remnants, in order to identify which anatomical features can be used in their segregation. From seven species 31 samples of Stryphnodendron were studied. Principal Component Analysis was used to evaluate wood anatomical characters. The species were separated into two main groups, congruent with the division into multifoliolate and paucifoliolate species, due to the presence of diffuse, lozenge-aliform and confluent axial parenchyma. In the multifoliolate group, although two subgroups were formed due to ray width in number of cells, none of the species were individualised, which corroborates previous findings of high morphological and anatomical similarities of the multifoliolate species.
The Piedra Chamana fossil woods (Eocene, Peru), II
Authors: Woodcock D.W. , Meyer H.W. , Prado Y.
Published: February 2019

This contribution presents descriptions of 14 fossil woods from the Piedra Chamana Fossil Forest in Peru, an assemblage of fossil woods and leaves dated at 39 Ma (late Middle Eocene). It is part two of the descriptions of the non-monocot angiosperm fossils from the site (see Woodcock et al. 2017). The woods are assigned to the subfamilies Bombacoideae, Bombacoideae/Malvoideae, Byttneroideae, Grewioideae, and Sterculioideae of Malvaceae and the families Melastomataceae, Muntingiaceae, Rubiaceae, Rutaceae, and Sapindaceae. Malvalean taxa make up around one-third of the wood types. Many of the woods are identifiable to modern-day genera or groups, including genera with species counted among the hyperdominant trees of the New World forests. Represented vegetation types include mixed freshwater swamp with Avicennia, seasonally flooded forest, and lowland tropical forest with a dry aspect. The assemblage shows floristic similarities to extant South American lowland tropical forest, particularly the seasonally flooded forests growing along white water rivers (várzea); however, the dry forest association has a less clear analog in the present-day tropics.

Mediostigmaeus gen. n. (Acari: Stigmaeidae), with the description of a new species from the USA
Authors: FAN QING-HAI , WALTER DAVID E.
Published: February 2019

A new genus, Mediostigmaeus is proposed for two species, M. citri (Rakha & McCoy, 1984) comb. n. and M. floridanus sp. n. The new genus is similar to Mediolata in having only one pair of subcapitular setae but can be easily distinguished by having the palptibial claw subequal to the palptarsus, and setae c 1 , d 1 , d 2 , e 1 , e 2 , and f 1 situated on individual platelets. The adult female of M. floridanus sp. n., collected from domatia of Vitis sp., Lake Adair, Orlando, Florida, USA can be separated from those of M. citri by chaetotaxy of tarsi and pattern of hysterosomal shield.

A new scorpionfish, Lioscorpius trifasciatus sp. nov., is described from material collected from the eastern Australian continental slope between Hinchinbrook Island (central Queensland) and Port Jackson (New South Wales) in 250–400 m depth. It differs from the only other member of the genus, the widely distributed Indo–West Pacific congener, L. longiceps Günther, in having the following combination of characters: 3 anal-fin spines (rather than 2), smaller head dimensions (i.e. length 38.7–42.3% SL, orbit 7.4–8.2% SL, upper jaw 19.1–20.7% SL, and maxilla depth 5.3–6.1% SL), shorter predorsal distance (36.2–38.8% SL), some relatively long fin elements (i.e. longest pelvic-fin ray 18.6–19.8% SL, first anal-fin spine 5.0–6.6% SL, and second anal-fin spine 10.4–12.7% SL), 3 diagonal red bands across the pectoral fin, and a red caudal-fin margin.

A new species of Opisthopatus Purcell, 1899 (Onychophora: Peripatopsidae) from KwaZulu-Natal, South Africa
Authors: RUHBERG HILKE , HAMER MICHELLE L.
Published: February 2019

The South African Peripatopsidae comprise two genera: Peripatopsis Pocock, 1894 (eight described species) and Opisthopatus Purcell, 1899 (two described species, and three subspecies currently debated). Recent collecting in South Africa produced a new and unusual onychophoran, Opisthopatus herbertorum sp. nov., from Mt. Currie Nature Reserve, KwaZulu-Natal. The new species is characterised by 17 pairs of legs, 15 complete dorsal plical folds per body segment, a lack of body-pigmentation, and reduced eyes. A key to the three species of Opisthopatus is provided. Other species of white onychophorans have been identified in South Africa, Australia and Jamaica; some of these species are cave-dwellers. The discovery of O. herbertorum sp. nov. from a small, isolated forest patch means that this species may be threatened with extinction, mainly through fire or other stochastic events. The habitat contains species of myriapods typical of forests, which suggests that the fauna is relictual, and that small forest patches have high conservation value. The discovery of the new species also highlights the lack of knowledge about forest invertebrates in South Africa, and raises the possibility of a far greater onychophoran diversity in the country.

Taxonomic revision of the geckos of the Gonatodes concinnatus complex (Squamata: Sphaerodactylidae), with description of two new species
Authors: STURARO MARCELO JOSÉ , AVILA-PIRES TERESA C. S.
Published: February 2019

The Gonatodes concinnatus complex, as here considered, consists of Gonatodes species characterized by a white suprahumeral spot with black margins; vermiculations or not on back; and transversely enlarged scales under the tail, showing the sequence 1’1’1”, and in some specimens 1’1’2” on the anterior portion. Two species are presently recognized in this Amazonian complex: G. concinnatus and G. tapajonicus. New material collected in eastern Amazonia (states of Pará and Amapá, Brazil) made it necessary to review these species. We analyzed several populations within this complex, from Colombia, Ecuador, Peru, Venezuela and Brazil, including these new records. Specimens were separated in groups defined on basis of color pattern. Stepwise discriminant function analyses were then performed to compare the external morphology (measurements and scale counts) in these groups. Results support recognition of five taxa, corresponding to G. concinnatus from western Amazonia, in Ecuador and northern Peru; G. ligiae from northwestern Venezuela (east of the Andes); G. tapajonicus, from the Tapajós river basin, in Pará, Brazil; and two new species, one from eastern Amazonia, in the states of Pará (north and south of the Amazon river) and Amapá, Brazil, and another from central Colombia, east of the Andes. Diagnoses and descriptions of all species are presented.
Andhracoides shabuddin gen. nov., sp. nov., a new phreatoicidean isopod (Crustacea, Hypsimetopidae) from hypogean aquatic habitats in Andhra Pradesh, India
Authors: WILSON GEORGE D. F. , REDDY YENUMULA RANGA
Published: February 2019

A decade-long survey of ground waters in the state of Andhra Pradesh, India, has so far yielded over sixty new crustacean taxa, belonging to Copepoda, Bathynellacea, Amphipoda, Isopoda, and Ostracoda. This paper describes a new genus and species attributable to the phreatoicidean isopod family Hypsimetopidae Nicholls, and provides ecological and behavioural observations. The new taxon was found in Guthikonda Cave, which is about 8 km from Piduguralla town in the Palnadu area of Andhra Pradesh State. The species belonging to this clade are unusual in that their dorsoventrally flattened pleotelson gives them a non-phreatoicidean appearance. Because the postanal margin is missing, as in other members of the Hypsimetopidae, this is a superficial similarity rather than homology with other isopods. Other unusual features include robust blunt denticles on opposing margins of the pleotelson and protopod of the uropods. The species in this clade, of which Andhracoides shabuddin gen. nov., sp. nov. is only the first to be described, are related to Nichollsia Chopra & Tiwari, found in northeastern India, and to Pilbarophreatoicus Knott & Halse from the Pilbara region of Western Australia. The new species differs from its undescribed congeners in being nearly devoid of dorsal setae; other species of Andhracoides gen. nov. are much more hirsute.
Centromedon zoe (Crustacea: Amphipoda: Lysianassoidea: Uristidae), a new deep-water scavenger species from the North Atlantic, with a key to the genus Centromedon
Authors: HORTON TAMMY , THURSTON MICHAEL
Published: February 2019

A new species of Centromedon Sars, 1891 is described based on abundant material collected in baited traps at 2500 m on the Mid-Atlantic Ridge. The species can be distinguished from the most closely allied species, Centromedon typhlops (Sars, 1879), Centromedon mediator (Barnard, 1962) comb. nov. and Centromedon laevis (Bonnier, 1896) comb. nov., by the form of the gnathopods, and characters of the mouthparts. A key to the eight species in the genus is provided. The differences between the closely allied genera Uristes Dana, 1849 and Centromedon are discussed.
Description of two new Aulacidae (Hymenoptera: Evanioidea) from Japan
Authors: TURRISI GIUSEPPE FABRIZIO , KONISHI KAZUHIKO
Published: February 2019

Two Aulacidae, Aulacus uchidai Turrisi & Konishi, sp. n. and Pristaulacus superbus Turrisi & Konishi, sp. n., are described and illustrated from females recently collected in Japan. Aulacus uchidai is recognizable among the other Palaearctic Aulacus by the colour pattern, with the metasoma entirely blackish, the weak and not extensive sculpture on upper frons, weakly rugulose-foveolate, the shape of mesosoma with propodeum declivous, the moderately long and slender apical lobe of hind coxa and the ovipositor length, 0.6–0.9× fore wing length. Pristaulacus superbus is a large species (length: 15.3–17.3 mm) with a long ovipositor (1.5× fore wing length), readily distinguishable from other Palaearctic Pristaulacus by the blue to dull green metallic hue on head and mesosoma, the entirely black metasoma and one tooth-like process on each side of hind surface of propodeum. Including the two new species, the number of Japanese Aulacidae is now nine, two species of Aulacus and seven species of Pristaulacus. Images of both species are freely available at the web site: http:/ /morphbank.net. A revised key for the identification of the Japanese Aulacidae is provided.

Published: February 2019

The polytene chromosomes are mapped for a scarce Himalayan simuliid, Simulium (Montisimulium) ghoomense Datta, from the Darjeeling area of India. This species has three tightly paired polytene chromosomes with a haploid number of 3. Chromosomes I, II, and III account for 39.6%, 30.3%, and 30.1% of the total complement length, respectively. The centromeres of chromosomes II and III consistently form a putative partial chromocenter. Sex chromosomes are undifferentiated and polymorphisms and sibling species are lacking in a sample of 35 larvae. This is the first chromosomal map for a species in the subgenus Montisimulium in India.

Recent Cyprididae and Ilyocyprididae (Crustacea: Ostracoda) from Lake Biwa, Japan, including a summary of the lake’s ostracod fauna
Authors: SMITH ROBIN J. , JANZ HORST , OKUBO ICHIRO
Published: February 2019

Sampling between 1999 and 2007 of the recent ostracod fauna of Lake Biwa, an ancient lake located in Japan, produced ten Cyprididae and one Ilyocyprididae species. One Cyprididae species, belonging to the genus Ilyodromus is described herein, Ilyodromus intermedius Okubo n. sp., and Bradleytriebella lineata (Victor & Fernando, 1981c) is redescribed. One Cyprididae species is a new record for Japan, namely Stenocypris malayica Victor & Fernando, 1981a, while seven others are new records for Lake Biwa. The family Ilyocyprididae is represented by only one species in Lake Biwa, Ilyocypris salebrosa Stepanaitys, 1960. The Lake Biwa population of this species is the first record of males and they are described in this paper. Including this study, forty ostracod species have now been reported from Lake Biwa. Most species (70%) were found at depths of less than 1 meter. Only four species were found below 44 m, the mean depth of the north basin.

Published: February 2019

Using the multiple tools available to support an online collaborative environment, we surveyed 62 morphological features from the hyoid arch and gill arches of 53 species of cypriniform fishes that matched those sampled in recent molecularanalyses and two sets of outgroup species (‘Saitoh outgroups’ and ‘Basal outgroups’). This is a skeletal region whose variation is considered historically significant within fishes and Cypriniformes in particular, and we review previous work in light of our own. The clarity of description of characters was enhanced by the use of a community reference ontology, the Teleost Anatomy Ontology. Terms, synonyms, and definitions for skeletal features from this region were contributed to this ontology, and links to these terms and relationships are included in our character descriptions. One thousand two hundred sixty-three images of features from this region were linked to ontology terms and deposited in a community image repository, Morphbank; these are linked to the characters described herein. Character data were analyzed using parsimony and Bayesian methods for two sets of outgroups, one of which matched that used in previous molecular analyses. The parsimony results, using either outgroup set, indicated similar higher-level relationships, including a sister group relationship between cyprinids and loaches. A basal trichotomy among Gyrinocheilus, catostomids and cyprinids + loaches was the result of Saitoh outgroup analysis in contrast to a sister group relationship between Gyrinocheilus and catostomids discovered in the Basal outgroup analysis. Interestingly, analyses including basal outgroups recovered a monophyletic Cyprinidae, consistent with all previous studies. Character evolution that supports higher-level nodes of interest in the consensus tree is described. In some respects, it might be a surprise that 62 morphological characters from a small skeletal region for only 53 cypriniform species (out of over 3,200 total species) could provide as much resolution as it does. We expect, however, further phylogenetic resolution as morphological data from across skeleton regions are combined, species sampling is increased, and molecular data are added.

Western boundary of the subfamily Danioninae in Asia (Teleostei, Cyprinidae): derived from the systematic position of Barilius mesopotamicus based on molecular and morphological data
Authors: LIAO TE-YU , ÜNLÜ ERHAN , KULLANDER SVEN O.
Published: February 2019

Analysis of mitochondrial cytochrome b sequences from 198 species confirms the position of Barilius mesopotamicus as a species of the Asian genus Barilius within the subtribe Chedrina in the subfamily Danioninae. This relationship is supported by a parsimony analysis based on 43 morphological characters, and the morphological examination confirms that B. mesopotamicus possesses the synapomorphies of the Danioninae and Chedrina, viz. absence of the Y-shaped ligament and the greatly reduced postcleithrum, respectively. Barilius mesopotamicus greatly expands the western boundary of the Asian Danioninae into the Tigris-Euphrates basin.
