Published: August 2019

Objectives

Puffing topographies of waterpipe users vary widely as does the puff-to-puff topography of an individual user. The aim of this study was to determine if puff duration and flow rate have an effect on the characteristics of the mainstream emission from waterpipes, including total particulate matter (TPM), mass ratio of nicotine and mass concentration of volatile carbonyls.

Methods

Puffing parameters were chosen to encompass a significant portion of the perimeter space observed from a natural environment study. Tested conditions were 150, 200 and 250 mL sec-1; each run at 2, 3.5 and 5 s durations; 25 s interpuff duration and ~100 puffs per session. Each session was run in quadruplicate using the Programmable Emissions System-2 (PES-2) emissions capture system under identical conditions. Particulate matter, for quantification of TPM and nicotine, was collected on filter pads every ~5 L of aerosol resulting in 6 to 25 samples per session. Volatile carbonyls were sampled using 2,4-Dinitrophenylhydrazine (DNPH)-coated silica.

Results

Mass concentration of TPM linearly decreased with increased flow rate, with no dependency on puff duration. Nicotine mass ratio was independent of topography, with average mass ratio of nicotine to TPM of 0.0027±0.0002 (mg/mg). The main carbonyls observed were acetaldehyde and formaldehyde. Puff duration increased emissions of some carbonyls (eg, formaldehyde) but not others (eg, acetaldehyde).

Conclusions

The results presented here highlight that topographies influence the emissions generated from waterpipes including TPM, total nicotine and volatile carbonyls. For laboratory studies to be representative of user exposure, a range of topographies must be studied. Using a range of topographies within a controlled laboratory environment will better inform regulatory policy.

Published: August 2019

Carbonatites are unusual alkaline rocks with diverse compositions. Although previous work has characterized the effects these rocks have on soils and plants, little is known about their impacts on local ecosystems. Using a deposit within the Great Lakes–St. Lawrence forest in northern Ontario, Canada, we investigated the effect of a carbonatite on soil chemistry and on the structure of plant and soil microbial communities. This was done using a vegetation survey conducted above and around the deposit, with corresponding soil samples collected for determining soil nutrient composition and for assessing microbial community structure using 16S/ITS Illumina Mi-Seq sequencing. In some soils above the deposit a soil chemical signature of the carbonatite was found, with the most important effect being an increase in soil pH compared with the non-deposit soils. Both plants and microorganisms responded to the altered soil chemistry: the plant communities present in carbonatite-impacted soils were dominated by ruderal species, and although differences in microbial communities across the surveyed areas were not obvious, the abundances of specific bacteria and fungi were reduced in response to the carbonatite. Overall, the deposit seems to have created microenvironments of relatively basic soil in an otherwise acidic forest soil. This study demonstrates for the first time how carbonatites can alter ecosystems in situ.
A 6.5-kV HBM ESD-protected high-gain LNA using cascaded L-match input network

Published: August 2019

A wideband (2–3 GHz) three-stage low noise amplifier (LNA) with electrostatic discharge (ESD) protection circuits using 0.18 [Formula: see text]m CMOS technology is presented in this paper. Low-parasitic silicon-controlled rectifier (SCR) devices are co-designed with the LNA in the form of [Formula: see text]-parameters, and a new cascaded L-match input network is proposed to reduce the parasitic effects of them on the input matching. To improve linearity performance, an optimized multiple-gated transistors method (MGTR) is proposed and applied to the third stage, which takes both transconductance [Formula: see text] and third-order nonlinear coefficient [Formula: see text] into consideration. The measured results show a wide input matching across 2–8 GHz and a high third-order input intercept point (IIP3) of −12.8 dBm. The peak power gain can achieve 29.1 dB, and the noise figure (NF) is in a range of 3.1–3.6 dB within the 3-dB bandwidth. Using SCR devices with low parasitic capacitance of [Formula: see text]80 fF and robust gate-driven power clamps, a 6.5-kV human body mode (HBM) ESD performance is obtained.
Multiple fermions in MoP
Authors: Sun Jian-Peng , Ji Qing , Li Yuan , Song Zhigang
Published: August 2019

Based on the first-principles calculation, we report that the WC-type MoP is a new type of topological semimetal. It can host Weyl semimetal phase with six pairs of Weyl points (WPs) in the first whole Brillouin zone (BZ). In the absence of spin-orbit coupling (SOC), band inversion forms a gapless nodal ring protected by horizontal mirror symmetry [Formula: see text]. The strong SOC in MoP makes the nodal ring fully gapped in the mirror plane, and generates multiple WPs away from the plane. As one hallmark of Weyl semimetals, the unique Fermi arcs are also observed by calculating the projected surface states and Fermi surfaces. Besides the above prodigious features, it also possess an additional four pairs of massless fermions with triply degenerate points (TDPs) in the vicinity of the Fermi level. Each TDP is a band crossing between degenerate and non-degenerate bands along the high-symmetry line in the Brillouin zone, and is protected by crystalline symmetries. Such new type of topological semimetal realizes multiple fermions states and further provides a fancy platform to study emergent physical phenomena.
Resonant multi-soliton solutions to two fifth-order KdV equations via the simplified linear superposition principle
Authors: Kuo Chun-Ku
Published: August 2019

In this paper, the simplified linear superposition principle is presented and employed to handle two versions of the fifth-order KdV equations, called the (2[Formula: see text]+[Formula: see text]1)-dimensional Caudrey–Dodd–Gibbon (CDG) equation and the (3[Formula: see text]+[Formula: see text]1)-dimensional generalized Kadomtsev–Petviashvili (KP) equation, respectively. Two general forms of resonant multi-soliton solutions are formally obtained. The paper proceeds step-by-step with increasing detail about the derivation process. Firstly, illustrate the algorithms of the linear superposition principle which paves the way for solving the wave related numbers. Then, demonstrate its application that exposes the proposed approach provides enough freedom to construct resonant multi-soliton wave solutions. Finally, some graphical representations of obtained solutions are portrayed by taking some definite values to free parameters, which describe various versions of inelastic interactions of resonant multi-soliton waves. The associated propagations may be related to large variety of real physical phenomena.

meso-Tetra(3,4,5-trimethoxy)phenyl-porphyrin and -tetrabenzoporphyrin and their phosphorus complexes were synthesized and their electronic absorption and magnetic circular dichroism (MCD) spectra discussed based on TD-DFT molecular orbital (MO) calculations. Nucleus-independent chemical shift (NICS) and anisotropy of the induced current density (ACID) calculations were also carried out for metal-free (and phosphorus) tetrabenzoporphyrins in order to discuss the aromaticity and flow of electrons in the molecule.
The Functional Stochastic Discount Factor
Authors: Tran Ngoc-Khanh
Published: August 2019

By assuming that the stochastic discount factor (SDF) [Formula: see text] is a proper but unspecified function of state variables [Formula: see text], we show that this function [Formula: see text] must solve a simple second-order linear differential equation specified by state variables’ risk-neutral dynamics. Therefore, this assumption determines the most general possible SDFs and associated preferences, that are consistent with the given risk-neutral state dynamics and interest rate. A consistent SDF then implies the corresponding state dynamics in the data-generating measure. Our approach offers novel flexibilities to extend several popular asset pricing frameworks: affine and quadratic interest rate models, as well as models built on linearity-generating processes. We illustrate the approach with an international asset pricing model in which (i) interest rate has an affine dynamic term structure and (ii) the forward premium puzzle is consistent with consumption-risk rationales; the two asset pricing features previously deemed conceptually incompatible.

This article deals with morphological tagging for low-resource languages. For this purpose, five Indic languages are taken as reference. In addition, two severely resource-poor languages, Coptic and Kurmanji, are also considered. The task entails prediction of the morphological tag (case, degree, gender, etc.) of an in-context word. We hypothesize that to predict the tag of a word, considering its longer context such as the entire sentence is not always necessary. In this light, the usefulness of convolution operation is studied resulting in a convolutional neural network (CNN) based morphological tagger. Our proposed model (BLSTM-CNN) achieves insightful results in comparison to the present state-of-the-art. Following the recent trend, the task is carried out under three different settings: single language, across languages, and across keys. Whereas the previous models used only character-level features, we show that the addition of word vectors along with character-level embedding significantly improves the performance of all the models. Since obtaining high-quality word vectors for resource-poor languages remains a challenge, in that scenario, the proposed character-level BLSTM-CNN proves to be most effective.

What Have Long-Term Field Studies Taught Us About Population Dynamics?
Authors: Reinke Beth A. , Miller David A.W. , Janzen Fredric J.
Published: August 2019

Long-term studies have been crucial to the advancement of population biology, especially our understanding of population dynamics. We argue that this progress arises from three key characteristics of long-term research. First, long-term data are necessary to observe the heterogeneity that drives most population processes. Second, long-term studies often inherently lead to novel insights. Finally, long-term field studies can serve as model systems for population biology, allowing for theory and methods to be tested under well-characterized conditions. We illustrate these ideas in three long-term field systems that have made outsized contributions to our understanding of population ecology, evolution, and conservation biology. We then highlight three emerging areas to which long-term field studies are well positioned to contribute in the future: ecological forecasting, genomics, and macrosystems ecology. Overcoming the obstacles associated with maintaining long-term studies requires continued emphasis on recognizing the benefits of such studies to ensure that long-term research continues to have a substantial impact on elucidating population biology.

The advent of molecularly targeted therapeutic agents has opened a new era in cancer therapy. However, many tumors rely on nondruggable cancer-driving lesions. In addition, long-lasting clinical benefits from single-agent therapies rarely occur, as most of the tumors acquire resistance over time. The identification of targeted combination regimens interfering with signaling through oncogenically rewired pathways provides a promising approach to enhance efficacy of single-agent–targeted treatments. Moreover, combination drug therapies might overcome the emergence of drug resistance. Here, we performed a focused flow cytometry–based drug synergy screen and identified a novel synergistic interaction between GLUT1-mediated glucose transport and the cell-cycle checkpoint kinases ATR and CHK1. Combined inhibition of CHK1/GLUT1 or ATR/GLUT1 robustly induced apoptosis, particularly in RAS-mutant cancer cells. Mechanistically, combined inhibition of ATR/CHK1 and GLUT1 arrested sensitive cells in S-phase and led to the accumulation of genotoxic damage, particularly in S-phase. In vivo, simultaneous inhibition of ATR and GLUT1 significantly reduced tumor volume gain in an autochthonous mouse model of KrasG12D-driven soft tissue sarcoma. Taken together, these findings pave the way for combined inhibition of GLUT1 and ATR/CHK1 as a therapeutic approach for KRAS-driven cancers.

Significance:

Dual targeting of the DNA damage response and glucose transport synergistically induces apoptosis in KRAS-mutant cancer, suggesting this combination treatment for clinical validation in KRAS-stratified tumor patients.

Although CD4+ T cells likely play key roles in antitumor immune responses, most immuno-oncology studies have been limited to CD8+ T-cell responses due to multiple technical barriers and a lack of shared antigens across patients. Merkel cell carcinoma (MCC) is an aggressive skin cancer caused by Merkel cell polyomavirus (MCPyV) oncoproteins in 80% of cases. Because MCPyV oncoproteins are shared across most patients with MCC, it is unusually feasible to identify, characterize, and potentially augment tumor-specific CD4+ T cells. Here, we report the identification of CD4+ T-cell responses against six MCPyV epitopes, one of which included a conserved, essential viral oncogenic domain that binds/disables the cellular retinoblastoma (Rb) tumor suppressor. We found that this epitope (WEDLT209-228) could be presented by three population-prevalent HLA class II alleles, making it a relevant target in 64% of virus-positive MCC patients. Cellular staining with a WEDLT209-228–HLA-DRB1*0401 tetramer indicated that specific CD4+ T cells were detectable in 78% (14 of 18) of evaluable MCC patients, were 250-fold enriched within MCC tumors relative to peripheral blood, and had diverse T-cell receptor sequences. We also identified a modification of this domain that still allowed recognition by these CD4+ T cells but disabled binding to the Rb tumor suppressor, a key step in the detoxification of a possible therapeutic vaccine. The use of these new tools for deeper study of MCPyV-specific CD4+ T cells may provide broader insight into cancer-specific CD4+ T-cell responses.
Microsatellite-Stable Tumors with High Mutational Burden Benefit from Immunotherapy

Published: August 2019

Programmed death receptor-1/ligand 1 (PD-1/L1) antibodies can induce durable remissions in malignancies. However, response rates are only approximately 10% to 20% in unselected patients versus approximately 50% in microsatellite instability–high (MSI-high) tumors, probably related to high tumor mutational burden (TMB). Pembrolizumab is approved for MSI-high or deficient mismatch repair tumors. However, outside of colorectal and endometrial carcinoma, only a small subset of tumors were MSI-high, making this treatment option unavailable to most patients. It is not known if MS-stable tumors with high TMB respond to PD-1/PD-L1 blockade. Next-generation sequencing (NGS) was performed on 60 patients (14 different histologies) treated with checkpoint blockade using the FoundationOne assay to determine TMB and MSI status. TMB was dichotomized into two groups: low-to-intermediate (0–19 mutations/mb) versus high (≥20 mutations/mb). Benefit rate (stable disease for ≥6 months and partial or complete response) was determined: 2,179 of 148,803 samples (1.5%) were MSI-high and 9,762 (6.6%) TMB-high (7,972, MS-stable/TMB-high). The majority (82.1%) of MSI-H tumors were TMB-high; however, only 18.3% of TMB-high tumors were MSI-H. Median progression-free survival for MS-stable/TMB-high versus MS-stable/TMB-low/TMB-intermediate tumors was 26.8 versus 4.3 months (P = 0.0173). Thus, our data demonstrate that MS-stable/TMB-high tumors are more common than MSI-high cancers and may benefit from immunotherapy.
Clinical Approach to Sodium Homeostasis Disorders in Children with Pituitary-Suprasellar Tumors
Authors: Tuli Gerdi , Matarazzo Patrizia , de Sanctis Luisa
Published: August 2019

Children with pituitary-suprasellar tumors are at high risk of developing sodium metabolism disorders since the tumoral mass itself or surgical and medical treatment can damage AVP release circuits. Additional risk factors are represented by the use of hypotonic fluids, the young age, total parenteral nutrition, and obstructive hydrocephalus secondary to tumor pathology. The most frequent hyponatremic disorders related to AVP in these patients are the syndrome of inappropriate ADH secretion and the cerebral/renal salt wasting syndrome, while hypernatremic conditions include central diabetes insipidus (CDI) and adipsic CDI. The main challenge in the management of these patients is to promptly distinguish the AVP release disorder at the base of the sodium imbalance and treat it correctly by avoiding rapid sodium fluctuations. These disorders can coexist or follow each other in a few hours or days; therefore, careful clinical and biochemical monitoring is necessary, especially during surgery, the use of chemotherapeutic agents, or radiotherapy. This monitoring should be performed by experienced healthcare professionals and should be multidisciplinary, including pediatric endocrinologists, neurosurgeons, and oncologists since maintaining sodium homeostasis also plays a prognostic role in terms of disease survival, therapeutic response, hospitalization rate, and mortality. In this review, we analyze the management of sodium homeostasis disorders in children with pituitary-suprasellar tumors and discuss the main challenges in the diagnosis and treatment of these conditions based on literature data and over 30 years of clinical experience at our Department of Pediatric Endocrinology.

Endovascular Occlusion Balloon for Treatment of Superior Vena Cava Tears During Transvenous Lead Extraction
Authors: Azarrafiy Ryan , Tsang Darren C. , Wilkoff Bruce L. , Carrillo Roger G.
Published: August 2019

Background:

Superior vena cava (SVC) tears are one of the most lethal complications in transvenous lead extraction. An endovascular balloon can occlude the SVC in the event of a laceration, preventing blood loss and offering a more controlled surgical field for repair. An early study demonstrated that proper use of this device is associated with reduced mortality. Thereafter, high-volume extractors at the Eleventh Annual Lead Management Symposium developed a best practice protocol for the endovascular balloon.

Methods:

We collected data on adverse events in lead extraction from July 1, 2016, to July 31, 2018. Data were prospectively collected from both a US Food and Drug Administration–maintained database and physician reports of adverse events as they occurred. We gathered case details directly from extracting physicians. Confirmed SVC tears were analyzed for patient demographics, case details, and index hospitalization mortality.

Results:

From July 1, 2016, to July 31, 2018, 116 confirmed SVC events were identified, of which 44.0% involved proper balloon use and 56.0% involved no use or improper use. When an endovascular balloon was properly used, 45 of 51 patients (88.2%) survived in comparison to 37 of 65 patients (56.9%) when a balloon was not used or improperly used (
P
=0.0002). Furthermore, multivariate regression modeling found that proper balloon deployment was an independent, negative predictor of in-hospital mortality for patients who experienced an SVC laceration (odds ratio, 0.13; 95% CI, 0.04–0.40;
P
<0.001).

Conclusions:

From July 1, 2016, through July 31, 2018, patients undergoing lead extraction were more likely to survive SVC tears when treatment included an endovascular balloon.
Three new species of Ancistrus Kner, 1854 (Siluriformes: Loricariidae) from the Rio Iguaçu basin, Paraná State, Brazil

Published: August 2019

The Rio Iguaçu basin, a tributary to the left bank of the Rio Paraná, is characterized by high endemism of fish species. Several specimens of Ancistrus, family Loricariidae, were recently caught in that river and they were attributed to three new species that are described herein. They can be diagnosed from their congeners by having short maxillary barbels which are not free from the lower lip, by lacking pre-anal fin plate and also by morphometric and meristic traits. Comments on the geographic distribution of those species and congeners are also provided, in addition to a key to the species from the Río de La Plata and coastal basins from southern Brazil.
Molecular phylogeny of Australian Gehyra (Squamata: Gekkonidae) and taxonomic revision of Gehyra variegata in south-eastern Australia
Authors: SISTROM MARK J. , HUTCHINSON MARK N. , HUTCHINSON RHONDA G. , DONNELLAN STEPHEN C.
Published: August 2019

We provide the first phylogenetic hypothesis for the Australian species of the gekkonid genus Gehyra, based on 1044bp of the mitochondrial ND2 gene. Species representing the Asian, Melanesian and Australian radiations are resolved as separate clades, indicating relative isolation and independence of each of these evolutionary lines. Within the Australian radiation, the arid zone species form a monophyletic subgroup distinct from the remaining species found in tropical and warm mesic habitats. Extensive chromosome variation and highly variable external morphology have made species recognition difficult within Gehyra, exacerbated by the likely presence of numerous undescribed cryptic species. Three species of Gehyra are currently recognized in the southeastern inland of Australia, G. variegata, G. montium and G. purpurascens. We re-describe a fourth species, G. lazelli, to include those populations long referred to informally as the 2n=44 chromosome ‘race’ of Gehyra variegata. Gehyra lazelli widely overlaps the distribution of G. variegata in South Australia and the southern inland of New South Wales, with no suggestion of intergradation in morphology, mitochondrial DNA, allozyme variation or karyotype.

The rare Andean pitviper Rhinocerophis jonathani (Serpentes: Viperidae: Crotalinae): redescription with comments on its systematics and biogeography
Authors: CARRASCO PAOLA A. , HARVEY MICHAEL B. , SARAVIA ARTURO MUÑOZ
Published: August 2019

Rhinocerophis jonathani is one of the few species of the Neotropical pitvipers that inhabit xeric areas at elevations above 2000 m in the Andes. We redescribe the species based on new specimens found in southern Bolivia and northwestern Argentina and provide new data on lepidosis, coloration, hemipenial morphology and the first description of cranial osteology. Rhinocerophis jonathani exhibits a suite of unusual features that are of systematic value within bothropoid genera. We compare the species with the phenotypically similar R. alternatus and the probably sympatric R. ammodytoides to address phylogenetic affinities. The new localities for Rhinocerophis jonathani extend the known range of the species southwards, provide data on its habitat and are the first records of its presence in Argentina. This pitviper occurs in a tropical-subtropical transition area in the Southern Andes and is likely to be derived from the Chacoan fauna.
Syngraph: An application for graphic display and interactive use of synonym lists

Published: August 2019

Multiple names that refer to a single species (synonyms) and more than one species being referred to by the same name (homonyms) bedevil taxonomy. They produce ambiguity about the entity under discussion. Syngraph is a computer application that organizes information about synonyms and homonyms. It can track different names that potentially have been applied to the same species, or identical names that have been applied to different species. It can create a list of synonyms in conventional format for use in publication, as for a taxonomic monograph. It can also display and print names so they are linked, thereby providing information on the conceptual basis of a name and the action taken in a publication. In the display, each name is imposed on a color-coded rectangle; all names on rectangles of the same color refer to records that stem from a single description. This allows quick visualization of the taxonomic history. When linked to a geographical information system application, the color can be used for points plotted on a map that displays the geographical locality of specimens referred to in each record. This visualization of the geographic distribution of the nominal species can provide tests of the hypothesis that the names are, indeed, synonyms. Syngraph is available for download; help files accompany the executable files.

Rhabdepyris (Epyrinae) is a cosmopolitan genus comprised of 132 species. No morphological synapomorphies are known for the genus and the genus is characterized by a combination of characters common to most Epyrini. Herein, we performed a cladistic analysis based on morphological characters to test the monophyly of Rhabdepyris. The three known subgenera of Rhabdepyris (Chlorepyris, Rhabdepyris s. str., and Trichotepyris) and other Epyrini (Anisepyris, Bakeriella, Calyozina, Epyris, Laelius, Trachepyris) were included in the ingroup. The cladistic analysis of 48 taxa (46 ingroup species and two outgroup species) and 81 structural characters yielded 72 cladograms under equal weights, and one under successive weighting. Rhabdepyris was found to be polyphyletic; the subgenus Trichotepyris was closely related to Anisepyris whereas Rhabdepyris str. s. was closely related to Laelius. The subgenus Chlorepyris is paraphyletic. Morphological characters are discussed in the light of the new phylogeny; novel characters are proposed and illustrated, and a new classification of Rhabdepyris and Epyrini is proposed. The following nomenclatural changes are proposed: Trichotepyris is synonymized under Anisepyris (syn. n.); Chlorepyris is recognized as a separated genus (stat. rev.); all 12 American species of the subgenus Rhabdepyris are transferred to Laelius; 22 species of Trichotepyris are transferred to Anisepyris; 58 species are transferred to Chlorepyris. A remaining total of 40 species are now recognized in Rhabdepyris. The holotype of Rhabdepyris, R. myrmecophilus Kieffer, the type species of Rhabdepyris, is redescribed.

Four new species of the Neotropical spider genus Enna (Araneae, Lycosoidea, Trechaleidae) from Brazil
Authors: DA SILVA ESTEVAM L. CRUZ , LISE ARNO A.
Published: August 2019

Currently, 24 species are known for the spider genus Enna O. Pickard-Cambridge, from North, Central and South America, of which six are known from Brazil. In this study four new species are described and illustrated based on female specimens from the Southeastern and Southern Brazilian states of Minas Gerais, São Paulo, Rio de Janeiro and Paraná. Enna trivittata sp. n., E. segredo sp. n., E. meridionalis sp. n. and E. caparao sp. n. can be distinguished from all known species by the general shape of the epigynum. New records in Brazil are presented for E. braslandia Silva, Lise & Carico and E. redundans (Platnick).
A new species of Nannosquilla (Stomatopoda: Nannosquillidae) from the Western Atlantic Ocean
Authors: DE ALBUQUERQUE DÉBORA LUCATELLI , COELHO PETRÔNIO ALVES
Published: August 2019

The family Nannosquillidae contains thirteen genera, one of which is Nannosquilla, composed of twenty-five species. The genus is distributed on both sides of the American continent, but contains no amphi-American species, and only one species in Indonesia. During surveys conducted in the Potiguar Basin, Rio Grande do Norte state/BR, a new species, Nannosquilla potiguara, was found. The new species is similar to N. schmitti, sharing the characters of seven intermediary fixed teeth in the posterior margin of telson on both side of the submedians movable tooth, and the inner spine on the uropodal protopod being longer than the outer. The two species differ in the number of teeth of the raptorial claw, in the morphology of rostral plate, and in the median projection of telson. From the Brazilian coast only one other species, N. dacostai, has previously been recorded. It is similar to new species in the subpentagonal rostral plate and the inner spine of uropodal protopod being longest, but N. potiguara n. sp. differ by a larger number of teeth on the dactylus of the raptorial claw and by fixed teeth on each side of the submedian movable teeth at telson. A key to the Atlantic species of Nannosquilla is given.
A new genus for three species of tyrant flycatchers (Passeriformes: Tyrannidae), formerly placed in Myiophobus
Authors: OHLSON JAN I. , FJELDSÅ JON , ERICSON PER G. P.
Published: August 2019

A new genus, Nephelomyias, is erected for three species of Andean tyrant flycatchers (Aves: Passeriformes: Tyrannidae) traditionally placed in the genus Myiophobus. An extensive study based on molecular data has shown that they form a well supported clade that is not closely related to other Myiophobus species. Instead, they form a small independent lineage in Tyrannidae, together with Pyrrhomyias, Hirundinea and Myiotriccus.
A redefinition of Iranothyas Bader, 1984 with the description of a new species from Oman
Authors: PESIC VLADIMIR , GERECKE REINHARD , SMIT HARRY
Published: August 2019

From a reinvestigation of the holotype of Iranothyas circularis (Schwoerbel & Sepasgozarian, 1976) results that this species was based on a female, not a male, as stated in the original description. The genus Iranothyas Bader, 1984, is redefined and Balaneothyas Gerecke, 1999 (monotypic, type species: B. marismortui Gerecke, 1999 from Israel) is recognized as its junior synonym. Bader's (1984) proposal to attribute Panisopsis orientalis Imamura & Mitchell, 1967 to Iranothyas is refused. A new, third species of Iranothyas, I. alhajarica n. sp., is described from Oman.

Pacific lowland snakes of the genus Atractus (Serpentes: Dipsadidae), with description of three new species
Authors: PASSOS PAULO , MUESES-CISNEROS JONH JAIRO , LYNCH JOHN D. , FERNANDES RONALDO
Published: August 2019

The taxonomic status of the Pacific lowland Atractus is revised on the basis of meristic, morphometric, colour pattern, and hemipenial characters. Geographical variation is reported for six Atractus species (A. boulengerii, A. clarki, A. iridescens, A. melas, A. multicinctus, and A. paucidens). Atractus boulengerii is rediscovered and redescribed from a specimen from the Colombian coast. The first voucher specimens are reported for A. melas. The current status of A. microrhynchus is maintained based on the discovery of new material referrable to that species. Three new species of Atractus are described from the Pacific lowland of Colombia: A. echidna sp. nov., A. medusa sp. nov., A. typhon sp. nov. Two new Atractus species groups (multicinctus and paucidens) are proposed based on external morphology, maxillary dentition, and hemipenial characters. A new key to Pacific lowland species of Atractus is provided.

Authors: LIU WENLIANG , LIU RUIYU
Published: August 2019

A new species, Michaelcallianassa sinica, from the Beibu Gulf (Tonkin Gulf), northern South China Sea, is described and illustrated. The new species is readily distinguished from M. indica Sakai, 2002, the type species of the genus, by its short uropodal endopod and exopod, and elongated carpus of the minor cheliped.
A revision of the endemic South African spider genus Austrachelas, with its transfer to the Gallieniellidae (Arachnida: Araneae)
Authors: HADDAD CHARLES R. , LYLE ROBIN , BOSSELAERS JAN , RAMIREZ MARTIN J.
Published: August 2019

The endemic South African spider genus Austrachelas Lawrence, 1938 is revised. The type species, A. incertus Lawrence, 1938, and A. natalensis Lawrence, 1942, are redescribed, and their males described for the first time. Seven new species are described: A. bergi n. sp. (female only), A. kalaharinus n. sp. (male only), A. merwei n. sp. (both sexes), A. pondoensis n. sp. (both sexes), A. reavelli n. sp. (both sexes), A. sexoculata n. sp. (male only), and A. wassenaari n. sp. (both sexes). A cladistic analysis performed including Austrachelas and various species of the corinnid subfamilies Trachelinae, Castianeirinae, Corinninae and Phrurolithinae, and species from the Liocranidae, Gallieniellidae, Gnaphosidae and Lamponidae, suggests that Austrachelas is currently misplaced. Its transfer to the Gallieniellidae is proposed.
A new xanthid crab of the genus Medaeops Guinot, 1967, from Peninsular Malaysia, with a note on Leptodius granulosus Haswell, 1882 (Crustacea: Decapoda: Brachyura: Xanthidae)
Authors: MENDOZA JOSE CHRISTOPHER E. , CHONG V. C. , NG PETER K. L.
Published: August 2019

A new species of Medaeops Guinot, 1967, is described from the western coast of Selangor, Peninsular Malaysia. Medaeops potens new species, is only the second species of the genus known to occur in this region, and is most similar to another relatively common western Pacific species, M. granulosus (Haswell, 1882), particularly by having a cristate anterior margin on the merus of the ambulatory legs. It can easily be distinguished from M. granulosus and other congeners on the characters of the carapace, chelipeds, ambulatory legs and male gonopods. The taxonomy of Leptodius granulosus Haswell, 1882, is also stabilized by the assignment of a lectotype from the existing type material.
New species of lysianassoid Amphipoda (Crustacea) associated with seamounts, marine canyons and cold seeps of New Zealand
Authors: KILGALLEN NIAMH M.
Published: August 2019

Lysianassoid amphipods collected from various habitats off the coast of New Zealand were examined. A total of seven species were found, representing five genera from three families. Six of these species are new to science. Such a high proportion of new species indicates that the marine amphipod fauna of New Zealand is still quite poorly known. The new species, Ensayara kermadecensis sp. nov., Ensayara ursus sp. nov., Galathella solivagus sp. nov., Hippomedon iugum sp. nov., Hippomedon hurleyi sp. nov. and Tryphosella moana sp. nov., are described in full.
A new species of Hoplosaenidea Laboissiere, 1933 from Malaysia (Coleoptera: Chrysomelidae: Galerucinae)
Authors: MOHAMEDSAID MOHAMED S.
Published: August 2019

Recently, the author described two species of the genus Hoplosaenidea Laboissiere, 1933 (Coleoptera: Chrysomelidae: Galerucinae) where the male having a peculiar secondary sexual characters: clypeus excavated, furnished with projections, and the antennal first segment large, broadened, excavated and spined at apex. The two species are H. takizawai Mohamedsaid, 2001 (Fig. 5) and H. singaporensis Mohamedsaid, 2002 (Fig. 6) described from Bali and Singapore, respectively. The presence of secondary sexual characters in males is most prevalent in the chrysomelid beetles of the subfamily Galerucinae (Mohamedsaid 2004b).
Molecular phylogeny in 'nano-weevils': description of a new subgenus Nanoacalles and two new species of Calacalles from the Macaronesian Islands (Curculionidae: Cryptorhynchinae)
Authors: ASTRIN JONAS J. , STÜBEN PETER E.
Published: August 2019

A molecular phylogeny for the eastern Atlantic weevil genus Calacalles Peyerimhoff, 1925 is presented, using two mitochondrial genes (CO1 and 16S). Based on a phylogenetic (Bayesian) analysis, we propose the following taxonomic amendments: the new subgenus Nanoacalles subg. n. is described and two new species, Calacalles hermigua sp. n. and Calacalles nataliae sp. n., are described from the Canarian island La Gomera and distinguished from other species of the genus. Calacalles palmensis (Roudier, 1954) (formerly Acalles wollastoni palmensis Roudier, 1954), which is illustrated here for the first time (habitus and aedeagus), is not a synonym of Acalles seticollis Wollaston, 1864, but a valid taxon. Calacalles subcarinatus (Israelson, 1984) from the Azores is assigned to the subgenus Crateracalles Stüben 2004. We also present a catalogue of all known Calacalles species.
