-Encoded Efflux Pump Be a Strategy To Preserve Currently or Resurrect Formerly Used Antibiotics To Treat Gonorrhea?
Authors: Chen Shaochun , Connolly Kristie L. , Rouquette-Loughlin Corinne , D’Andrea Alexander , Jerse Ann E. , Shafer William M.
Published: August 2019

The emergence of gonococcal strains resistant to past or currently used antibiotics is a global public health concern, given the estimated 78 million infections that occur annually. The dearth of new antibiotics to treat gonorrhea demands that alternative curative strategies be considered to counteract antibiotic resistance expressed by gonococci. Herein, we show that decreased expression of a drug efflux pump that participates in gonococcal resistance to antibiotics can increase gonococcal susceptibility to beta-lactams and macrolides under laboratory conditions, as well as improve antibiotic-mediated clearance of gonococci from the genital tract of experimentally infected female mice.

Bacteria adapt to infections by evolving variants that are more fit and persistent. These recalcitrant variants are typically observed in chronic infections. However, it is unclear when and why these variants evolve. To address these questions, we used a porcine chronic wound model to study the evolutionary dynamics of
Pseudomonas aeruginosa
in a mixed-strain infection. We isolated hyperbiofilm variants that persisted early in the infection. Interstrain interactions were also observed, where adapted variants acquired CRISPR-mediated immunity to phages. We show that when initiating infection,
P. aeruginosa
experiences strong positive selection for hyperbiofilm phenotypes produced by mutants of a single chemosensory system, the Wsp pathway. We predict that hyperbiofilm variants are early adaptations to infection and that interstrain interactions may influence bacterial burden and infection outcomes.
Aggregation of Nontuberculous Mycobacteria Is Regulated by Carbon-Nitrogen Balance
Authors: DePas William H. , Bergkessel Megan , Newman Dianne K.
Published: August 2019

Free-living bacteria can assemble into multicellular structures called biofilms. Biofilms help bacteria tolerate multiple stresses, including antibiotics and the host immune system. Nontuberculous mycobacteria are a group of emerging opportunistic pathogens that utilize biofilms to adhere to household plumbing and showerheads and to avoid phagocytosis by host immune cells. Typically, bacteria regulate biofilm formation by controlling expression of adhesive structures to attach to surfaces and other bacterial cells. Mycobacteria harbor a unique cell wall built chiefly of long-chain mycolic acids that confers hydrophobicity and has been thought to cause constitutive aggregation in liquid media. Here we show that aggregation is instead a regulated process dictated by the balance of available carbon and nitrogen. Understanding that mycobacteria utilize metabolic cues to regulate the transition between planktonic and aggregated cells reveals an inroad to controlling biofilm formation through targeted therapeutics.

Published: August 2019

EMCV is an animal pathogen that causes acute viral infections, usually myocarditis or encephalitis. It is thought to circulate mainly among rodents, from which it is occasionally transmitted to other animal species, including humans. EMCV causes fatal outbreaks of myocarditis and encephalitis in pig farms and zoos, making it an important veterinary pathogen. Although EMCV has been widely used as a model to study mechanisms of viral disease in mice, little is known about its entry mechanism. Here, we employ a haploid genetic screen for EMCV host factors and identify an essential role for ADAM9 in EMCV entry.

Published: August 2019

Sponges represent ecologically important models to understand the evolution of symbiotic interactions of metazoans with microbial symbionts.
Thaumarchaeota
are commonly found in sponges, but their potential adaptations to a host-associated lifestyle are largely unknown. Here, we present three novel sponge-associated thaumarchaeal species and compare their genomic and predicted functional features with those of closely related free-living counterparts. We found different degrees of specialization of these thaumarchaeal species to the sponge environment that is reflected in their host distribution and their predicted molecular and metabolic properties. Our results indicate that
Thaumarchaeota
may have reached different stages of evolutionary adaptation in their symbiosis with sponges.
Highly Reproducible 16S Sequencing Facilitates Measurement of Host Genetic Influences on the Stickleback Gut Microbiome
Authors: Small Clayton M. , Currey Mark , Beck Emily A. , Bassham Susan , Cresko William A.
Published: August 2019

Our findings demonstrate the importance of appropriately quantifying biological and technical variance components when attempting to understand major influences on high-throughput microbiome data. Our focus was on understanding among-host (biological) variance in community metrics and its magnitude in relation to within-host (technical) variance, because meaningful comparisons among individuals are necessary in addressing major questions in host-microbe ecology and evolution, such as heritability of the microbiome. Our study design and insights should provide a useful example for others desiring to quantify microbiome variation at biological levels in the face of various technical factors in a variety of systems.
Operating department practitioners and adult nurses: interprofessional education bedfellows or a bridge too far?
Authors: Taylor Natasha , Horwood Gemma , Kneafsey Rosie
Published: August 2019

Background

Interprofessional education (IPE) is well embedded in undergraduate health curricula. However, scant literature exists on which health and care disciplines, such as adult nurses and operating department practitioners (ODPs), prefer to work within simulated learning events.

Methods

This study took place over a number of simulated interprofessional events, with a range of health and care disciplines students, using a variety of simulation tools. The total number of participants was: adult nurses 16 and ODPs 18.

Results

An ordinal logistic regression analysis was carried out on survey data collected. The OR of ODPs choosing adult nurses as the discipline they would prefer to work with at these events was 1.994 (95% CI 1.034 to 3.334) times that of adult nurses choosing ODPs as the discipline they would prefer to work with at these events, a statistically significant effect.

Conclusions

It is clear that a statistical difference in preferential choice exists, with ODPs choosing to work with adult nurses almost twice that of adult nurses choosing to work with ODPs. This supports the importance of IPE and the understanding of other professions, to improve team working across health and care organisations.

It has been estimated that one-third of global food is lost or wasted, entailing significant environmental, economic, and social costs. The scale and impact of food loss and waste (FLW) has attracted significant interest across sectors, leading to a relatively recent proliferation of publications. This article synthesizes existing knowledge in the literature with a focus on FLW measurement, drivers, and solutions. We apply the widely adopted DPSIR (Driver-Pressure-State-Impact-Response) framework to structure the review. Key takeaways include the following: Existing definitions of FLW are inconsistent and incomplete, significant data gaps remain (by food type, stage of supply chain, and region, especially for developing countries), FLW solutions focus more on proximate causes rather than larger systemic drivers, and effective responses to FLW will require complementary approaches and robust evaluation.
Narrativas de Genji no período Meiji (1868-1912): do ponto de vista da relação literatura e estado
Authors: Kufukihara Rei
Published: August 2019

We pick up three people’s works from Meiji era concerned with The Tale of Genji, written in the 11thcentury. The first one, a translation of The Tale of Genji done by a young diplomat established in the UK in order to show to the great powers of that country how much the Japanese culture was a high-level one. The next one, a novel by Ichiyo Higuchi, influenced by The Tale of Genji, is about a young girl who is sold by her own parents to prostitution. The novel’s name refers to the impossibility of the Japanese nation-state to deal with common people and children. The last one, a poem by Akiko Yosano cries out against the Russo-Japanese war. The reason why is that Akiko accepted various human feelings that appear in The Tale of Genji: delight, sadness and heartbreaking. For Akiko, such human feelings are more important than the war by the nation-state. So she criticizes even the Emperor Meiji as the top of the command hierarchy. Ichiyo does not cry against the contradiction of Japanese state and makes it clearly by writing the heroin’s behavior and mentality in a lively way. For these two women, Ichiyo and Akiko, The Tale of Genji is not only the classical literature, but works as the encouraging recognition of reality.

Published: August 2019

Background:

Impaired myocardial conduction is the underlying mechanism for re-entrant arrhythmias. Carbon nanotube fibers (CNTfs) combine the mechanical properties of suture materials with the conductive properties of metals and may form a restorative solution to impaired myocardial conduction.

Methods:

Acute open chest electrophysiology studies were performed in sheep (n=3). Radiofrequency ablation was used to create epicardial conduction delay after which CNTf and then silk suture controls were applied. CNTfs were surgically sewn across the right atrioventricular junction in rodents, and acute (n=3) and chronic (4-week, n=6) electrophysiology studies were performed. Rodent toxicity studies (n=10) were performed. Electrical analysis of the CNTf-myocardial interface was performed.

Results:

In all cases, the large animal studies demonstrated improvement in conduction velocity using CNTf. The acute rodent model demonstrated ventricular preexcitation during sinus rhythm. All chronic cases demonstrated resumption of atrioventricular conduction, but these required atrial pacing. There was no gross or histopathologic evidence of toxicity. Ex vivo studies demonstrated contact impedance significantly lower than platinum iridium.

Conclusions:

Here, we show that in sheep, CNTfs sewn across epicardial scar acutely improve conduction. In addition, CNTf maintain conduction for 1 month after atrioventricular nodal ablation in the absence of inflammatory or toxic responses in rats but only in the paced condition. The CNTf/myocardial interface has such low impedance that CNTf can facilitate local, downstream myocardial activation. CNTf are conductive, biocompatible materials that restore electrical conduction in diseased myocardium, offering potential long-term restorative solutions in pathologies interrupting efficient electrical transduction in electrically excitable tissues.

Published: August 2019

Rationale:

Cardiac involvement and hypotension dominate the prognosis of light-chain amyloidosis (AL). Evidence suggests that there is also peripheral vascular involvement in AL but its prognostic significance is unknown.

Objective:

To evaluate vascular dysfunction in patients with AL as a potential future area of intervention, we assessed the prognostic utility of flow-mediated dilatation (FMD), a marker of vascular reactivity, which is augmented under conditions of hypotension and autonomic dysfunction.

Methods and Results:

We prospectively evaluated 115 newly diagnosed untreated AL patients in whom FMD was measured. FMD in AL patients was significantly higher than age-, sex- and risk factors–matched controls (4.0% versus 2.32%;
P
=0.006) and comparable with control groups at lower cardiovascular risk (
P
>0.1). Amyloidosis patients presented increased plasma and exhaled markers of the NO pathway while their FMD significantly correlated with augmented sustained vasodilatation after sympathetic stimulation. Increased FMD (≥4.5%) was associated with early mortality (hazard ratio, 4.36; 95% CI, 1.41–13.5;
P
=0.010) and worse survival (hazard ratio, 2.11; 95% CI, 1.17–3.82;
P
=0.013), even after adjustment for Mayo stage, nerve involvement and low systolic blood pressure. This finding was confirmed in a temporal validation AL cohort (n=55; hazard ratio, 4.2; 95% CI, 1.45–12.3;
P
=0.008). FMD provided significant reclassification value over the best prognostic model (continuous Net Reclassification Index, 0.61;
P
=0.001). Finally, better hematologic response was associated with lower posttreatment FMD.

Conclusions:

FMD is relatively increased in AL and independently associated with inferior survival with substantial reclassification value. Reactive vasodilation merits further investigation as a novel risk biomarker in AL.Visual Overview: An online visual overview is available for this article.
Exercise-Induced Cardiac Troponin I Increase and Incident Mortality and Cardiovascular Events

Published: August 2019

Background:

Blood concentrations of cardiac troponin above the 99
th
percentile are a key criterion for the diagnosis of acute myocardial injury and infarction. Troponin concentrations, even below the 99
th
percentile, predict adverse outcomes in patients and the general population. Elevated troponin concentrations are commonly observed after endurance exercise, but the clinical significance of this increase is unknown. We examined the association between postexercise troponin I concentrations and clinical outcomes in long-distance walkers.

Methods:

We measured cardiac troponin I concentrations in 725 participants (61 [54–69] yrs) before and immediately after 30 to 55 km of walking. We tested for an association between postexercise troponin I concentrations above the 99
th
percentile (>0.040 µg/L) and a composite end point of all-cause mortality and major adverse cardiovascular events (myocardial infarction, stroke, heart failure, revascularization, or sudden cardiac arrest). Continuous variables were reported as mean ± standard deviation when normally distributed or median [interquartile range] when not normally distributed.

Results:

Participants walked 8.3 [7.3–9.3] hours at 68±10% of their maximum heart rate. Baseline troponin I concentrations were >0.040 µg/L in 9 participants (1%). Troponin I concentrations increased after walking (
P
<.001), with 63 participants (9%) demonstrating a postexercise troponin concentration >0.040 µg/L. During 43 [23–77] months of follow-up, 62 participants (9%) experienced an end point; 29 died and 33 had major adverse cardiovascular events. Compared with 7% with postexercise troponin I ≤0.040 µg/L (log-rank
P
<.001), 27% of participants with postexercise troponin I concentrations >0.040 µg/L experienced an end point. The hazard ratio was 2.48 (95% CI, 1.29–4.78) after adjusting for age, sex, cardiovascular risk factors (hypertension, hypercholesterolemia or diabetes mellitus), cardiovascular diseases (myocardial infarction, stroke, or heart failure), and baseline troponin I concentrations.

Conclusions:

Exercise-induced troponin I elevations above the 99
th
percentile after 30 to 55 km of walking independently predicted higher mortality and cardiovascular events in a cohort of older long-distance walkers. Exercise-induced increases in troponin may not be a benign physiological response to exercise, but an early marker of future mortality and cardiovascular events.
Renal and Lumbar Sympathetic Nerve Activity During Development of Hypertension in Dahl Salt-Sensitive Rats

Published: August 2019

To study the contribution of sympathetic nerve activity (SNA) to the development of hypertension, experiments were designed to continuously and simultaneously measure renal (RSNA) and lumbar SNA (LSNA) during the development of hypertension induced by 8% salt loading in Dahl salt-sensitive (DS) rats. Male DS and salt-resistant rats were instrumented with bipolar electrodes to record RSNA and LSNA and a telemeter to record arterial pressure (AP). AP increased during the first 3 days after the onset of salt loading by ≈10 mm Hg in both DS and Dahl salt-resistant rats. AP continued to increase progressively from day 4 to day 14 of salt loading by 33±1 mm Hg in DS rats, while it remained the same in Dahl salt-resistant rats. RSNA and LSNA increased in the initial few days by 6% to 8%, and decreased gradually thereafter, suggesting that increases in neither RSNA nor LSNA are directly linked with the progressive increase in AP induced by salt loading in DS rats. After the cessation of salt loading, AP pressure returned to the presalt loading level in both DS and Dahl salt-resistant rats. RSNA increased significantly by 32±3% after the cessation of salt loading, while LSNA remained the same in DS rats, suggesting that salt-sensitive mechanisms respond to a loss of sodium, not a gain, and selectively activate RSNA in DS rats. In summary, RSNA and LSNA are not likely to be a primary trigger to initiate the progressive increase in AP induced by 8% salt loading in DS rats.

The International Society of Peritoneal Dialysis recommends that adequate blood pressure (BP) assessment among patients on peritoneal dialysis should at least include measurements performed once-weekly at home and at each visit at clinic. However, the quality of evidence to support this guidance is suboptimal. Using ambulatory daytime BP as reference standard, we explored the diagnostic performance of clinic and home BP recordings in a cohort of 81 stable patients receiving peritoneal dialysis. BP was recorded using 3 different methodologies: (1) triplicate automated clinic BP recordings after a 5-minute seated rest with the validated monitor HEM 705 CP (Omron Healthcare); (2) 1-week averaged home BP recorded with a validated automated monitor on awaking and at bedtime; and (3) ambulatory BP monitoring with the Mobil-O-Graph device (IEM, Germany). The area under the curve of receiver operating characteristic curves in detection of ambulatory daytime systolic BP (SBP) ≥135 mm Hg was similar for clinic [area under the curve, 0.859; 95% CI, 0.776–0.941] and home SBP (area under the curve, 0.895; 95% CI, 0.815–0.976). In Bland-Altman analysis, clinic SBP overestimated daytime ambulatory SBP by 5.02 mm Hg with 95% limits of agreement ranging from −17.92 to 27.96 mm Hg. Similarly, home SBP overestimated daytime ambulatory SBP by 4.23 mm Hg, again with wide 95% limits of agreement (−16.05 to 24.51 mm Hg). These results show that 1-week averaged home SBP is of at least similar accuracy with standardized clinic SBP in diagnosing hypertension confirmed by ambulatory BP monitoring among patients on peritoneal dialysis.
Finding Common Ground: Negotiating Downstream Rights to Harvest with Upstream Responsibilities to Protect—Dairies, Berries, and Shellfish in the Salish Sea
Authors: Norman Emma S.
Published: August 2019

Harvesting shellfish is an important cultural and economic activity for coastal Indigenous communities throughout the Salish Sea. However, for the Lhaq’temish People of Lummi Nation, upstream agricultural pollution has rendered this inherent right impossible for almost two decades. In an attempt to reopen the shellfish beds, Lummi Nation leaders developed the Portage Bay Partnership, which aims to address the upstream pollution problem through relationship building and shared connection to place. The partnership brings to light several key points: (1) efforts to integrate different community views of place to develop a relational approach to shared water governance, (2) the use of legal tools to incentivize relationship building, and (3) the continued challenges associated with competing governance frameworks and worldviews. This partnership opposes a system that has been set up to systemically exclude or disenfranchise Indigenous communities, replacing a governance model based on acquired rights with one that prioritizes relationships and responsibilities.
Rendering Technical, Rendering Sacred: The Politics of Hydroelectric Development on British Columbia’s Saaghii Naachii/Peace River
Authors: Behn Caleb , Bakker Karen
Published: August 2019

This article analyzes debates over the Site C Dam on the Saaghii Naachii/Peace River in northeastern British Columbia (BC), Canada. After heated debate over the past several decades, construction on the CN$10 billion hydroelectric project—the largest in the province’s history—recently commenced. The article focuses on debates over the analysis and adjudication of cumulative effects, and concomitant treaty rights infringement, within the environmental review process. The shortcomings of the regulatory review process used to assess cumulative effects are analyzed in two ways: first, by a conventional academic assessment, and second, by a Dunne-Za teaching of the interrelationships between land, water, and animals in the dam-affected region. Through juxtaposing these two modes of analysis, the article engages with scholarship in political ecology and Indigenous political theory.

Published: August 2019

Published literature on the echinoderms of Montenegro (the south Adriatic Sea) is still very scarce. As a baseline for future studies that will enhance the knowledge of this fauna, we have compiled a checklist combining the existing published data with original data from a recent research. The checklist of the echinoderm fauna of the Montenegrin part of the south Adriatic Sea includes 57 species, grouped into 39 genera and 30 families, of which one crinoid (Crinoidea), 18 asteroids (Asteroidea), 9 ophiuroids (Ophiuroidea), 15 echinoids (Echinoidea), and 14 holothurians (Holothuroidea), which makes 56.4% of the species recorded so far in the Adriatic Sea, and 37.0% of the current total number of Mediterranean echinoderms. Ten recorded species are Mediterranean endemics, and two are Mediterranean subendemics. Six species are new for the fauna of Montenegro.
Description of three new species of the deep-sea munnopsid genus Belonectes (Crustacea, Isopoda, Asellota) from the Weddell Sea, Southern Ocean

Published: August 2019

Three new species of the genus Belonectes Wilson & Hessler, 1981, from the munnopsid subfamily Eurycopinae Hansen are described from the deep Weddell Sea, Atlantic sector of the Southern Ocean. Belonectes grasslei sp. nov., B. stoddarti sp. nov., and B. daytoni sp. nov. are the first species of the genus described from the region: previously only two species of Belonectes were known from the northeastern Atlantic and the Peru-Chile Trench, the southeastern Pacific. The modified diagnosis of the genus Belonectes and a key to the species of the genus are presented. The pattern of the total ventral sculpture of the natasome, a medial lobe of article 4 of the maxillipedal palp which is larger than article 5 and the navicular male pleopod 1 with its deep keel are suggested to be additional important generic characters of Belonectes. The most useful characters to distinguish species of Belonectes are the size of article 1 of the antennula, the shape and size of the articles 3–5 of the maxillipedal palp, the shape of the distal margin of the male pleopod 1, the shape of distolateral part of the protopod of the male pleopod 2, the size and shape of the preanal ridge, and the size of the exopod of the uropod.

Authors: STĘPIEŃ ANNA , BŁAŻEWICZ-PASZKOWYCZ MAGDALENA
Published: August 2019

Two new species of the apseudomorphan tanaidacean genus Tanzanapseudes are described from coral reefs of Western Australia. This genus belongs to the monogeneric family Tanzanapseudidae, which is recorded here for the first time from Australia. Tanzanapseudes nieli n. sp. differs from the other members of the genus by a specific pattern of minute spines and setae on pereonites, and by a combination of two other characters: a pleotelson distal process with a smooth outer margin and a short and spinose first article in the antennule. T. levis n. sp. has the anterolateral processes on its carapace and distal processes on its pleotelson uniquely smooth. A key for identification of Tanzanapseudes species and an amended diagnosis are given.

Cladistic analysis of Megachile (Chrysosarus) Mitchell and revalidation of Megachile (Dactylomegachile) Mitchell (Hymenoptera, Megachilidae)
Authors: DURANTE SILVANA , CABRERA NORA
Published: August 2019

Megachile is the largest genus of the family Megachilidae, being widely distributed throughout temperate and tropical areas of the world. The validity of M. (Chrysosarus) and M. (Dactylomegachile) was investigated based on a cladistic analysis of 63 characters of adult morphology of 14 taxa. The single most parsimonious tree (181 steps, CI=0.60; RI=0.63) resulting from an implied weighting analysis recovered M. (Chrysosarus) and M. (Dactylomegachile) as monophyletic groups. Both subgenera are redescribed and the value of the most frequently used characters in the taxonomy of Megachile is discussed.
Recognizing taxonomic units in the fieldThe case of the crickets Oecanthus dulcisonans Gorochov 1993, and O. pellucens (Scopoli, 1763) (Orthoptera: Gryllidae): implications for their distribution and conservation in Southern Europe
Authors: CORDERO PEDRO J. , LLORENTE VICENTA , CORDERO PAU , ORTEGO JOAQUÍN
Published: August 2019

Recognizing taxonomic units in the field complement classical museum taxonomy. It contributes to geographical distribution assessment making possible the recognition of conservation status of conflictive and similar species. In this paper, we provide unambiguous field characters distinguishing two similar species of Oecanthus in Southern Europe: Oecanthus dulcisonans Gorochov and O. pellucens (Scopoli) that are frequently misidentified. Whereas O. dulcisonans is a southern rare species with an uncertain status and distribution, O. pellucens is common and widely distributed in the Palaearctic. Song is the easiest way to distinguish between the two species in the field being continuous in the former and with regular schemes in the latter. Further, O. dulcisonans is larger, with relatively longer inner wings protruding more apically from tegmen, and with a more slender sternum, morphological traits that are detected simply with a hand magnifier.

These names are listed and annotated after searching the relevant taxonomic and economic literature published since 1758. Where possible, we give the current status for each name and discuss names of species that we regard as unrecognisable. We transfer Coccus stipulaeformis Haworth to the genus Ceroplastes as Ceroplastes stipulaeformis (Haworth) comb. n., and we also synonymise Coccus alchemillae Walker with Porphyrophora polonica (Linnaeus) syn. n., Coccus conchiformis Gmelin with Coccus conchiformis Goeze syn. n., Coccus clematitis Goeze with Parthenolecanium persicae persicae (Fabricius) syn. n., Coccus mespili Goeze with Pulvinaria vitis (Linnaeus) syn. n., Coccus arbuti Turton with Eriococcus uvaeursi (Linnaeus) syn. n., and Coccus cacti v. silvestris Meunier with Dactylopius tomentosus (Lamarck) syn. n..
Contributions to the knowledge of the Staphylinus-complex (Coleoptera: Staphylinidae: Staphylinini) of China. Part 21. The genus Ocypus Leach, 1819, subgenus Pseudocypus Mulsant & Rey, 1876. Section 4
Authors: SMETANA ALEŠ
Published: August 2019

The paper deals with the species of the picipennis- and fuscatus-lineages of the subgenus Pseudocypus Mulsant & Rey, 1876 of the genus Ocypus Leach, 1819, known to occur at present on the territory of the People’s Republic of China, in the Russian Far East, and in Japan. Eight species are treated, all previously described: O. picipennis (Fabricius, 1793), O. helleni (J. Müller, 1926), O. aenescens Eppelsheim, 1889, O. inexspectatus Eppelsheim, 1887, O. shiretokensis Hayashi, 2008, O. graeseri Eppelsheim, 1887, O. fuscatus (Gravenhorst, 1802) and O. nigroaeneus Sharp, 1889. Based on the study of the type material, the following new synonymies are proposed: Staphylinus (Pseudocypus) rambouseki J. Müller, 1925 and Pseudocypus fuscatoides Coiffait, 1964 are placed in synonymy with Ocypus (Pseudocypus) graeseri Eppelsheim, 1887. Ocypus eppelsheimi Reitter, 1887 is transfered to the genus Miobdelus Sharp, 1889 (comb. nov.); Miobdelus montivagus Smetana, 2001 becomes a junior objective synonym of it (syn. nov.). Lectotypes are designated for Ocypus helleni, Ocypus rambouseki, Ocypus nigroaeneus and Ocypus eppelsheimi. Neotype is designated for Ocypus graeseri Eppelsheim, 1887. Each species is described, illustrated and all available distributional and bionomic data are given. A key to the species of the picipennis- and fuscatus-lineages of the subgenus Pseudocypus, that occur in People’s Republic of China, in the Russian Far East, and in Japan, is given.

Synopsis of Lytopsenella Kieffer (Hymenoptera: Bethylidae)
Authors: AZEVEDO CELSO O.
Published: August 2019

Lytopsenella Kieffer, 1905, is a Bethylinae genus with two species and is hitherto restricted to southern Chile. The genus is recognized by having the marginal cell in the fore wing closed and elongate. The goal of this study is to summarize the taxonomic knowledge of the species. L. herbsti (Kieffer, 1904) and L. testaceicornis (Kieffer, 1910) are revised and illustrated. Additional taxonomic variations are added and geographic distributions are broadened. Lytopsenella is recorded from Argentina for the first time. A key for both species are provided.
Description of the final instar nymph of Homeoura nepos (Selys, 1876) (Odonata: Coenagrionidae)
Authors: TENNESSEN KENNETH J.
Published: August 2019

The description of the nymph of Homeoura nepos (Selys, 1876) by Calvert (1948) was based on a single, immature specimen from São Paulo, Brazil which lacked gills. The nymphs of H. chelifera (Selys) and H. lindneri (Ris) were described by Lozano et al. (2009), who considered Calvert's description of the nymph of H. nepos doubtful.

A review of of the Holarctic Sepedon fuscipennis and S. spinipes groups with description of a new species (Diptera: Sciomyzidae)
Authors: ELBERG KAUPO , ROZKOŠNÝ RUDOLF , KNUTSON LLOYD
Published: August 2019

Two holarctically distributed species groups of Sepedon, S. fuscipennis (5 spp.) and spinipes (2 spp.) are reviewed. The diagnostic characters of all species are compared and the distinguishing structures of the male terminalia are illustrated. The Palaearctic Sepedon hecate sp. nov. is described and compared with the Nearctic species of the S. fuscipennis group. The new species is distributed mainly in the East Palaearctic but apparently penetrates to Central Europe. A detailed study of the male terminalia of the Palaearctic S. spinipes spinipes (Scopoli, 1763) and the Nearctic S. spinipes americana Steyskal, 1951 shows that the Nearctic taxon actually represents a well distinguished species, S. americana Steyskal, 1951, stat. nov.
A review of the pontoniine shrimp genus Rapipontonia Marin, 2007 (Decapoda: Caridea: Palaemonidae), with the description of a new species from the Indo-West Pacific
Authors: MARIN IVAN
Published: August 2019

A review of hydroid-associated pontoniine shrimp genus Rapipontonia Marin, 2007 is presented. The genus is characterized by a highly specific prehensile mechanism of the ambulatory pereiopods that allows clinging to their hosts. A new species is described from Vietnam and Indonesia distinguished from the most similar species, R. paragalene Marin, 2007, by longer rostrum, longer carpus of the minor second pereiopod in females and the number of unpaired spines on the distoventral margin of propodus of the ambulatory pereiopods. A new record of Rapipontonia galene (Holthuis, 1951) from Hawaii significantly extends the known range of the species. A revised key for the identification of all species of the genus is given. Based on morphology of mature females and distribution of individuals per hosts observed in Vietnam, a sex-role reversal mechanism is suggested for the first time within the subfamily.
Comments on the snake-eel genus Xyrias (Anguilliformes: Ophichthidae) with the description of a new species
Authors: McCOSKER JOHN E. , CHEN WEI-LI , CHEN HONG-MING
Published: August 2019

Comments on the snake-eel genus Xyrias (Anguilliformes: Ophichthidae) with the description of a new species. Xyrias chioui, a new robust snake-eel species, subfamily Ophichthinae, is described on the basis of a specimen caught at 60–70 m depth on a benthic longline off Changbin, Taitung County, eastern Taiwan. It is distinguished from its congeners by having fewer vertebrae (126), 3 postorbital cephalic pores, and biserial rather than multiserial mandibular dentition. A key to the species of Xyrias is provided. Additional records of X. revulsus from the Arafura Sea and off New South Wales, Australia, extend its depth range from a few to 300 meters. The generic diagnosis of Xyrias is expanded such that the maxillary dentition ranges from a biserial to a multiserial condition.
Buotidae, a new family for the minute North American milliped Buotus carolinus (Chamberlin) 1940 (Diplopoda, Chordeumatida, Striarioidea)
Authors: SHEAR WILLIAM A.
Published: August 2019

Buotus carolinus (Chamberlin) 1940, a minute, rarely collected but relatively widespread milliped of the mid-Atlantic region of the United States, was originally described as a member of the order Polyzoniida, family Polyzoniidae. Shear (1981) correctly placed the species in the order Chordeumatida and argued for assignment to the suborder Craspedosomatidea, superfamily Brannerioidea, family Tingupidae. New studies of fresh specimens using the scanning electron microscope, however, revealed characters inconsistent with this placement and instead support inclusion of Buotus in the suborder Striariidea, superfamily Striarioidea. Because the species cannot be accommodated in any of the established families of this superfamily, a new family Buotidae is herein erected to receive it.
Two new species of habronematid nematodes (Nematoda: Spirurida: Habronematidae) in birds of prey from West Java, Indonesia with a key to species of Torquatoides
Authors: ZHANG LUPING , DEWI KARTIKA , PURWANINGSIH ENDANG
Published: August 2019

Two new species of habronematid nematodes are described from Gunung Ciremai National Park, West Java, Indonesia. Procyrnea javaensis n. sp., collected from the gizzard of the Collared Scops Owl, Otus bakkamoena lempiji, can be distinguished from P. brevicaudata as the left side of body lacks two longitudinal ridges, in having a ventral rather than a sinistral vulvar opening, and in the shape of the female tail. The new species differs from P. ficheuri in shape of the left spicule, and in having asymmetrical caudal alae; from P. murrayi in shape of the left spicule; from P. ameerae by having a longer left spicule, different spicule ratio and one median preanal papilla; from P. dollfusi and P. aptera in the spicule ratio and in having a shorter female tail, and from P. haliasturi in the spicule ratio and in having a post-equatorial versus pre-equatorial vulva. Torquatoides noerdjitoi n.sp. collected from the gizzard of Sunda Frogmouth, Batrachostomus javensis javensis, can be distinguished from T. torquata, T. bengalensis, and T. crotophaga in lacking lateral alae. The new species differs from T. balanocephala in numbers of cuticular plaques and precloacal papillae; from T. singhi in having longer bodies, numbers of precloacal papillae, longer spicules, and in the egg size; and from T. trogoni in the numbers of precloacal papillae, in the shapes of right spicule and gubernaculum.
A new species of Malagasy blind snake of the genus Typhlops Oppel (Serpentes: Typhlopidae)
Authors: RENOULT JULIEN P. , RASELIMANANA ACHILLE P.
Published: August 2019

Madagascar is the third hottest biodiversity hotspot in the world with regard to the reptile fauna, after the Caribbean and middle-America (Myers et al. 2000). Moreover, 92% of the 365 described species are endemic to the island (Glaw & Vences 2007). Malagasy snakes of the family Typhlopidae are no exception to this pattern of endemism: except for the cosmopolitan, widespread and introduced Ramphotyphlops braminus (Daudin, 1803), all the other species of the family encountered in Madagascar are endemic to the island. The species are allocated into two genera: Xenotyphlops (endemic to Madagascar) and Typhlops (with a worldwide distribution). However, when contrasted with other tropical forests worldwide, and given the extraordinarily high rates of micro-endemism characterizing several reptile lineages on Madagascar (Yoder et al. 1995), the current species richness in Malagasy blind snakes is relatively low: only eight species are recognized in the genus Typhlops and two in Xenotyphlops (Glaw & Vences 2007). The opportunistic discovery of a Typhlops, that could not be assigned to any named taxon, close to a widely frequented research station of the eastern humid forest highlights the limited survey efforts in this region. The purpose of this paper is to describe this new taxon and to stress the need to increase field investigations in the eastern rain forest.
New taxa and new records of Australian Panchaetothripinae (Thysanoptera, Thripidae)
Authors: MOUND LAURENCE A.
Published: August 2019

A new genus and species of panchaetothripine thripid, Stosicthrips szitas, apparently related to Parthenothrips dracaenae, is described from leaves of a cultivated Grevillea (Proteaceae) in central Queensland and also at Perth, Australia. In another genus, Bhattithrips, a new species B. borealis is described from northern Australia, and the four members of this Australian genus are distinguished in a key. A species described from Southeast Asia, Astrothrips aureolus, is established and probably native to northern Australia, where it damages the leaves of an Hymenocallis cultivar (Amaryllidaceae).

Two new genera and species of chiltoniid amphipods (Crustacea: Amphipoda: Talitroidea) from freshwater mound springs in South Australia
Authors: KING RACHAEL A.
Published: August 2019

Amphipods within the family Chiltoniidae are an abundant yet taxonomically poorly known member of Australian freshwater habitats. With only four species known from Australia, the group is inadequately defined and marked by taxonomists as difficult to identify. Recent molecular analyses of chiltoniids from mound springs in South Australia detected several distinct species, prompting a morphological revision of material from the central and southern Lake Eyre region. Clear groups defined by unique combinations of morphological characters (focusing on uropodal, coxal, male gnathopod 2, and antennal morphology) were found that closely correlated with clades found in the molecular analyses. Arabunnachiltonia n. gen. is established for A. murphyi n. sp. from Strangways Springs in South Australia. Wangiannachiltonia n. gen. is established for W. guzikae n. sp. from Davenport Springs in South Australia. The chiltoniid genera are discussed and a key is presented to the known Australian species.
