Published: March 2024

Aim: Sodium-glucose co-transporter 2 (SGLT2) inhibitors have emerged as a vital part of management of type 2 diabetes, as they have been shown to have both cardiovascular and renal benefits along with an improved survival rate in several randomized clinical trials. We designed a retrospective cohort study to investigate the impact of SGLT2 inhibitors on mortality among type 2 diabetes patients. Methods: Patients with type 2 diabetes who presented to the Dasman Diabetes Institute in Kuwait were followed from January 1st, 2015, until January 20th, 2023. To control for non-random allocation of SGLT2 inhibitors and measured confounders, we performed one-to-one propensity score matching and evaluated outcomes in the matched cohorts using a Cox proportional hazards model. The primary treatment variable was SGLT2 inhibitor use; time to mortality from any cause was used as the outcome of interest. Results: 1,551 patients were taking SGLT2 inhibitors, and 1,687 patients were not. After propensity score matching, 845 patients were on SGLT2 inhibitors, and 845 patients were not. In post-matching analysis, all-cause mortality was higher among patients who did not take SGLT2 inhibitors compared to patients taking SGLT2 inhibitors (5.2 vs. 2.1%, p = 0.0012). The hazard ratio of all-cause mortality in patients taking SGLT2 inhibitors was 0.42 (95% confidence interval [95% CI], 0.24–0.72). Additional adjustment of matching factors did not change the results. Conclusion: This observational study demonstrated substantial long-term reduction in mortality risk among patients with type 2 diabetes treated with SGLT2 inhibitors. This is irrespective of the stage of their renal diseases or GLP1 agonist.

Published: March 2024

Introduction: Adenosquamous carcinoma (ASC) of the ampulla of Vater (AmV) is rare. The prognosis is generally worse in patients undergoing resection of ASC of the AmV than in those undergoing resection of adenocarcinoma of the AmV because the former shows early recurrence after surgery. A treatment strategy for ASC of the AmV has not been established, and the efficacy of adjuvant chemotherapy after curative resection is unclear. Given the paucity of data, we report a case of ASC of the AmV that was curatively resected and treated with adjuvant chemotherapy. Case Presentation: A 66-year-old man presented with pruritus and anorexia. Contrast-enhanced computed tomography revealed a tumor measuring 1.6 cm in diameter located at the AmV and distal bile duct. Biopsy revealed adenocarcinoma of the AmV. The patient underwent subtotal stomach-preserving pancreaticoduodenectomy. Histopathological examination contradictorily revealed ASC of the AmV and lymph node metastases. The postoperative course of the patient was uneventful, and he was discharged on day 25. The patient underwent S-1 adjuvant chemotherapy for 6 months and did not exhibit any postoperative recurrence for a follow-up duration of 28 months. Conclusion: Although treatment strategy for ASC of the AmV has not been established, our case shows that surgery followed by S-1 adjuvant chemotherapy could improve prognosis of patients with such tumors. However, further research is required to determine the efficacy of adjuvant chemotherapy and treatment strategies for resectable ASC of the AmV.
From Hair Loss to Vision Loss: Minoxidil-Associated CRVO in a Young Female
Authors: Pickel Lauren , Ji Patrick Xiang , Abdelazim Amr , Sivachandran Nirojini
Published: March 2024

Introduction: Central retinal vein occlusion (CRVO) is a common retinal vascular disorder that is most often seen in older adults and individuals with vascular risk factors. Case Presentation: We report a case of CRVO with cystoid macular edema (CME) in a young, otherwise healthy patient taking minoxidil for hair loss. The patient had no known vascular risk factors, and a comprehensive coagulability workup was negative. The CRVO with CME resolved without intervention upon cessation of minoxidil. Conclusion: Possible mechanisms for minoxidil-associated retinal vascular disorders are explored. Thorough medication histories and the consideration of possible adverse drug events in patients without traditional risk factors are recommended.
Os nomes de Júlio Bressane: jogos de sentido nas conversações cinematográficas
Authors: Macedo Lennon , Leites Bruno
Published: March 2024

O artigo analisa as formas com que a nomeação de personagens configura as conversações cinematográficas dos filmes de Júlio Bressane como atos de fala cujo sentido ruma à proliferação de devires e à produção de indecidibilidade. A partir das investigações de Gilles Deleuze e Félix Guattari, desdobramos o estatuto de ato de fala da conversa no cinema, evidenciando o caráter acontecimental do sentido da conversação quando é atravessada pelo ato de nomear. O estudo dos nomes no cinema bressaneano se dá a partir da análise de blocos extraídos dos filmes Brás Cubas (1985) e O mandarim (1995), nos quais o sentido das nomeações expressa uma conversação que preza a tensão entre o já vivido e o ainda por vir.
Circulating Branched Chain Amino Acids and Cardiometabolic Disease
Authors: Fine Keenan S. , Wilkins John T. , Sawicki Konrad T.
Published: March 2024

Branched chain amino acids (BCAAs) are essential for protein homeostasis, energy balance, and signaling pathways. Changes in BCAA homeostasis have emerged as pivotal contributors in the pathophysiology of several cardiometabolic diseases, including type 2 diabetes, obesity, hypertension, atherosclerotic cardiovascular disease, and heart failure. In this review, we provide a detailed overview of BCAA metabolism, focus on molecular mechanisms linking disrupted BCAA homeostasis with cardiometabolic disease, summarize the evidence from observational and interventional studies investigating associations between circulating BCAAs and cardiometabolic disease, and offer valuable insights into the potential for BCAA manipulation as a novel therapeutic strategy for cardiometabolic disease.

Published: March 2024

Background

Restrictive cardiomyopathy (RCM) is characterized by impaired diastolic function with preserved ventricular contraction. Several pathogenic variants in sarcomere genes, including
TNNI3
, are reported to cause Ca
2+
hypersensitivity in cardiomyocytes in overexpression models; however, the pathophysiology of induced pluripotent stem cell (iPSC)‐derived cardiomyocytes specific to a patient with RCM remains unknown.

Methods and Results

We established an iPSC line from a pediatric patient with RCM and a heterozygous
TNNI3
missense variant, c.508C>T (p.Arg170Trp; R170W). We conducted genome editing via CRISPR/Cas9 technology to establish an isogenic correction line harboring wild type
TNNI3
as well as a homozygous
TNNI3
‐R170W. iPSCs were then differentiated to cardiomyocytes to compare their cellular physiological, structural, and transcriptomic features. Cardiomyocytes differentiated from heterozygous and homozygous
TNNI3
‐R170W iPSC lines demonstrated impaired diastolic function in cell motion analyses as compared with that in cardiomyocytes derived from isogenic‐corrected iPSCs and 3 independent healthy iPSC lines. The intracellular Ca
2+
oscillation and immunocytochemistry of troponin I were not significantly affected in RCM‐cardiomyocytes with either heterozygous or homozygous
TNNI3
‐R170W. Electron microscopy showed that the myofibril and mitochondrial structures appeared to be unaffected. RNA sequencing revealed that pathways associated with cardiac muscle development and contraction, extracellular matrix‐receptor interaction, and transforming growth factor‐β were altered in RCM‐iPSC‐derived cardiomyocytes.

Conclusions

Patient‐specific iPSC‐derived cardiomyocytes could effectively represent the diastolic dysfunction of RCM. Myofibril structures including troponin I remained unaffected in the monolayer culture system, although gene expression profiles associated with cardiac muscle functions were altered.
Impact of Secondary Amenorrhea on Cardiovascular Disease Risk in Physically Active Women: A Systematic Review and Meta‐Analysis
Authors: Tegg Nicole L. , Myburgh Caitlynd , O'Donnell Emma , Kennedy Megan , Norris Colleen M.
Published: March 2024

Background

Exercise‐associated secondary amenorrhea results in estrogen deficiency, which may lead to dysfunction in estrogen's normal cardioprotective pathways. Estrogen may be essential in a woman's endothelial adaptations to exercise. The objective of this review was to assess the association between secondary amenorrhea in physically active women and cardiovascular disease (CVD) risk.

Methods and Results

A literature search was performed in January 2023 and updated in August 2023 of the Cumulative Index to Nursing and Allied Health Literature (EBSCOhost), Cochrane Library, Embase (Ovid), MEDLINE (Ovid), SPORTDiscus (EBSCOhost), and Scopus from inception to present with no date or language limitations. Citation chaining was done to screen for additional studies. Eight sources were searched for gray literature. Studies that compared physically active women with amenorrhea to physically active women with eumenorrhea aged 18 to 35 years with evidence of CVD, alterations to cardiovascular physiology, or CVD risks were included. Eighteen observational studies from 3 countries were included. Overall, the quality of evidence was good. A meta‐analysis was performed. Physically active women with secondary amenorrhea had significantly lower estradiol, flow‐mediated dilation, resting heart rate, systolic blood pressure, and diastolic blood pressure and higher total cholesterol, triglycerides, high‐density lipoprotein, and low‐density lipoprotein cholesterol.

Conclusions

Estrogen deficiency resulting from exercise‐associated secondary amenorrhea in physically active women may impact cardiovascular physiology and certain CVD risk factors. The research in this area is observational; therefore, findings should be interpreted cautiously. However, as exercise‐associated secondary amenorrhea is reversible and the primary prevention of CVD is important for public health, it may be important to treat secondary amenorrhea and restore estrogen levels.
Family-Leave Mandates and Female Labor at U.S. Firms: Evidence from a Trade Shock
Authors: Kamal Fariha , Sundaram Asha , Tello-Trillo Cristina J.
Published: March 2024

We examine how the 1993 Family and Medical Leave Act (FMLA) impacts the gender composition at U.S. firms experiencing a negative demand shock. Combining changes in Chinese imports across industries between 2000 and 2003 and a sharp regression discontinuity to identify FMLA status, we find that an increase in import competition decreases the share of female employment, earnings, and promotions at FMLA relative to non-FMLA firms. This effect is driven by women in prime childbearing ages and without college degrees; and is pronounced at firms with all male managers. These results suggest that job-protected leave mandates may exacerbate gender inequalities in response to adverse shocks.
Misspecified Exponential Regressions: Estimation, Interpretation, and Average Marginal Effects
Authors: Silva J.M.C. Santos , Winkelmann Rainer
Published: March 2024

Exponential regressions are frequently used when outcomes are non-negative. They are attractive because they are easy to interpret and to estimate, using pseudo maximum likelihood (PML). However, the validity of these methods depends on the correct specification of the conditional expectation, and little is known regarding their properties when the conditional expectation is misspecified. We show that PML estimators of misspecified exponential models provide optimal approximations to the conditional expectation, in a weighted mean squared error sense, and we give conditions under which their Poisson PML estimator identifies average marginal effects.
The inordinate unpopularity of changing all eponymous bird and other organismal names
Authors: WINKER KEVIN
Published: March 2024

A proposal by Foley & Rutter (2020) to eliminate all eponymous English bird names was published in the Washington Post, a Washington D.C. newspaper. Fears (2021) reported in this same newspaper that a racist and colonialist history is perpetuated in some English bird names, especially eponyms, and that a social movement is working to change those names. These articles generated hundreds of online comments. I used sentiment analysis on these comments to quantify public reaction to this proposal and topic. Among the 340 scored comments to Foley & Rutter (2020), negative opinions outnumbered positive ones by 3.36:1. Scoring comments by relative magnitude of their sentiment (-3, -2, -1, 0, 1, 2, 3) yielded an average score of -1.18. These results indicate this proposed action is very unpopular among these readers and causes pronounced divisiveness. The 570 scored comments to the Fears (2021) article were also negatively skewed (2.3:1), though less so (average score -0.58). Politicization and the left-right nature of the issue were rampant in the comments on both articles, indicating that the subject was immediately brought into the culture wars (i.e., conflict between liberal and conservative groups over cultural issues). The divisive nature of the topic was also evident within self-identified left-leaning respondents. These results likely underestimate public negativity to this proposal, because the Washington Post is a left-leaning newspaper. Similarly, Guedes et al. (2023) called for eliminating all eponymous organismal names, and a sentiment analysis of comments about that article was even more starkly negative, showing 90 % of commenters opposed. More data like these are needed. There is considerable risk that broadly de-commemorating eponymous organismal names will create more negative than positive outcomes (e.g., through asymmetric polarization and the culture wars). We must also ask: does excluding people who do not share our views achieve our objective of inclusiveness? When is it acceptable to take away someone’s hard-won knowledge by changing key terms in our shared biodiversity linguistic infrastructure? There are more constructive ways to address diversity, equity and inclusion.
Description of the tadpole of Itapotihyla langsdorffii (Anura: Hylidae)
Authors: PIMENTA BRUNO V. S. , CANEDO CLARISSA
Published: March 2024

The tadpole of Itapotihyla langsdorffii is described and illustrated. Morphological data are compared with available information on tadpoles of casque-headed frogs occurring in the Atlantic Rainforest (genera Aparasphenodon and Trachycephalus), and also with Osteocephalus. The ontogenetic shift in tooth row formula and the great similarity on tadpole external morphology among these genera do not allow the use of the examined larval characters on generic diagnoses. However, we present some juvenile characters which may support the validity of Itapotihyla. The confrontation of the hypotheses concerning oral disk morphology and larval habitat types of the casque-headed tree frogs with the phylogeny of the Lophiohylini indicates that the ancestral larval habitat of this tribe was lentic and that the high number of tooth rows in this clade is not related to larval habitat.

A chronological catalog of the New World species of Scolopendra L., 1758 (Chilopoda: Scolopendromorpha: Scolopendridae)
Authors: SHELLEY ROWLAND M.
Published: March 2024

Since 1758, 140 names have been erected for, transferred into, or assigned to species of Scolopendra occurring in the New World.  One hundred sixteen are from definite, though sometimes vague, type localities; 18 are for nominal species without type localities; three lack standing in nomenclature and are invalid; and three are nomina nuda.  To facilitate future studies and determining synonymies, these names are cataloged in chronological order in four listings plus a summary roster of senior names and junior subjective synonyms.  Additional rosters cite primary homonyms needing rectification and species needing neotypes — ones with revisitable type localities, ones with unknown or overly generalized type localities that cannot be rechecked, and ones whose type specimens may still exist.  The Mexican species, S. robusta Kraepelin, 1903, inadvertently reduced to subspecific status under S. gigantea L., 1758, in a popularized booklet, is returned to full specific status and deleted from Colombia, and S. punctiscuta Wood, 1861, is placed in synonymy under S. heros Girard, 1853, which is deleted from India.  Scolopendra sumichrasti Saussure, 1860, & S. olmeca Humbert & Saussure, 1969, are possible synonyms of S. pomacea C. L. Koch, 1847.  The synonymy of S. viridilimbata Daday, 1891, under S. polymorpha Wood, 1861, is accepted, and the following established synonymies are confirmed: under S. alternans Leach, 1815 — S. sagraea Gervais, 1837, S. cubensis Saussure, 1860, S. complanata, S. multispinata, & S. grayi, all by Newport, 1844, and S. torquata & S. testacea, both by Wood, 1861; under S. subspinipes Leach, 1815 — S. sexspinosa Newport, 1844, and S. placea & S. lutea, both by Newport, 1845; under S. morsitans L., 1758, S. brandtiana Gervais, 1837, and S. pella Wood, 1861; and under S. viridicornis Newport, 1844, S. punctidens Newport, 1844.  The following generic assignments are confirmed: S. lobidens Newport, 1844, in Cormocephalus Newport, 1845; and S. cormocephalina Kohlrausch, 1878, S. longipleura Silvestri, 1895, and S. chilensis & S. pallida, both by Gervais, 1847, in Hemiscolopendra Kraepelin, 1903.  Scolopendra viridicornis Newport, 1844, a plausible inhabitant of Guyana, is deleted from Cuba and the Lesser Antilles.  The publication date of S. alternans Leach, previously thought to be 1813, is corrected to 1815, and that of S. arthrorhabdoides Ribaut, previously cited as both 1912 and 1914, is established as 1913.
Neverita delessertiana (Récluz in Chenu, 1843): a naticid species (Gastropoda: Caenogastropoda) distinct from Neverita duplicata (Say, 1822) based on molecular data, morphological characters, and geographical distribution
Authors: HÜLSKEN THOMAS , CLEMMENSEN MARINA , HOLLMANN MICHAEL
Published: March 2024

The members of the caenogastropod family Naticidae show highly conserved morphological characters, which in many cases complicate species separation. In such cases DNA sequence analysis may help to distinguish between species. In this work partial sequences from the small mitochondrial ribosomal RNA (16S rRNA) gene, the small nuclear ribosomal RNA (18S rRNA) gene, a short intron of the nuclear calmodulin (Cal) gene, and the mitochondrial cytochrome oxidase subunit I (COI) gene are shown to differ significantly between the genomes of what generally had been considered to be merely two morphological variants of the common Western Atlantic naticid Neverita duplicata (Say, 1822). Sequence differences between the two forms of Neverita duplicata are similar to differences between either of these two forms and the Eastern Pacific Neverita reclusiana (Deshayes, 1839), the Indopacific Neverita didyma (Röding, 1798), and the Mediterranean Neverita josephinia (Risso, 1826). The COI sequences divergence between the two forms of Neverita duplicata is in the range of the average COI sequences divergence reported for congeneric species of Mollusca (Hebert 2003). We conclude that in addition to Neverita duplicata a second shallow water species of Neverita exists along the US Atlantic and Gulf coasts for which the name Neverita delessertiana (Récluz, 1843) is available.
A new European species of Pegomya Robineau-Desvoidy (Diptera: Anthomyiidae) near P. flavoscutellata (Zetterstedt)
Authors: MICHELSEN VERNER
Published: March 2024

A new species of Pegomya Robineau-Desvoidy is described from Europe (Sweden, Denmark and Finland) by the name of P. curviphallis. It belongs, together with the Holarctic P. flavoscutellata (Zetterstedt) and the Nearctic P. flaviantennata Griffiths, in a species group defined by a sickle-shaped distiphallus. Differential descriptions are given for the two European species of the P. flavoscutellata species group, P. curviphallis sp. nov. and P. flavoscutellata. Larvae of P. flavoscutellata are known to feed on bolete mushrooms (Leccinum spp.), and a similar larval diet can be expected in other species of the P. flavoscutellata species group.

Astacilla boreaphilis sp. nov. (Crustacea: Isopoda: Valvifera) from shallow and deep North Atlantic waters
Authors: STRANSKY BENTE , SVAVARSSON JÖRUNDUR
Published: March 2024

Astacilla boreaphilis sp. nov. is described from shallow and deep waters off Iceland and Greenland. A. boreaphilis sp. nov. is easily distinguished from all but one of the Astacilla species recorded from the North Atlantic by the absence of eyes and from all other Astacilla species by the pattern of the spines on the body. The species shows pronounced sexual dimorphism. The species occurs at depths between 219 and 1809 m and at temperatures between 2.4°C and 7.2°C. The species is therefore restricted to Atlantic Water (AW), characterizing the area south of the Greenland–Iceland–Færoe Ridge and to Atlantic Water presumably diluted by cold water masses from the Nordic Seas. The depth range in the area differs locally and may be limited by cold water currents crossing the Ridge.

Two new and exceptional poison dart frogs of the genus Dendrobates (Anura: Dendrobatidae) from the Northeastern Flank of the cordillera Central of Colombia
Authors: RUEDA-ALMONACID JOSÉ VICENTE , RADA MARCO , SÁNCHEZ-PACHECO SANTIAGO J. , VELÁSQUEZ-ÁLVAREZ ÁLVARO ANDRÉS , QUEVEDO ALONSO
Published: March 2024

We name and describe two new species of poison dart frogs of the genus Dendrobates, from the northeastern flank of the cordillera Central in the departamentos de Tolima and Caldas. Those frogs share an exceptional synapomorphy within the family, which consists of a first toe reduced and fused with the second toe, allowing only four toes to be seen externally. Perhaps this unusual characteristic is reason to create a new genus within the Dendrobatidae, however, this must await a period of further investigation of the phylogeny of these two species, including a molecular and  anatomic analysis. Elucidating the taxonomic position of these species and the naming a new genus, if found to be appropriate and applicable, will be the subject of a future manuscript.
Studies on New Guinean giant stick-insects of the tribe Stephanacridini Günther, 1953, with the descriptions of a new genus and three new species of Stephanacris Redtenbacher, 1908 (Phasmatodea: "Anareolatae")

Published: March 2024

The genus Hermarchus STÅL, 1875 (type-species: Phibalosoma pythonius Westwood, 1859) is an artificial taxon. The new genus Macrophasma n. gen. (type-species: Hermarchus biroi Redtenbacher, 1908) is described to contain all New Guinean species currently in Hermarchus Stål, as these differ considerably from the type-species of Hermarchus Stål from Fiji by various features of the insects and eggs. Hermarchus biroi Redtenbacher, 1908, H. lyratus Redtenbacher, 1908 and H. oreitrephes Günther, 1929 are transferred to Macrophasma n. gen.. Hermarchus annulatus Günther, 1929 and H. muelleri Redtenbacher, 1908 are shown to be synonyms of H. biroi Redtenbacher, 1908 (n. syn.). A lectotype is designated for M. biroi (Redtenbacher, 1908) with the egg described and illustrated. Three new species of the genus Stephanacris Redtenbacher, 1908 from New Guinea are described and illustrated from the & & and eggs: Stephanacris draconius n. sp. from Papua New Guinea, Stephanacris multilobatus n. sp. from southeast West Papua and Stephanacris laeviceps n. sp. from northwest West Papua. Holotypes are deposited in ZSMC and RMNH, paratypes in the first and second author’s collections.

Morphology and biology of Polydora species (Polychaeta: Spionidae) boring into oyster shells in South America, with the description of a new species
Authors: RADASHEVSKY VASILY I. , LANA PAULO C. , NALESSO ROSEBEL C.
Published: March 2024

Four Polydora species boring into oyster shells in South America are described based on museumand new material collected mainly in Brazil. These include P. cf. haswelli newly recorded for South America, P. ecuadoriana and P. rickettsi newly recorded for the Atlantic coast of South America, and a new species described from Brazil. Extension of the distribution of these oyster-associated species may have resulted from transportation of oysters to South America for aquaculture. In all species, females deposit eggs into capsules which are joined to each other in a string and attached to the inner wall of the burrow. In P. ecuadoriana, P. cf. haswelli and P. rickettsi, larvae develop inside the capsules until the 3-chaetiger stage and then are released into the water column where they feed and develop until the 16–18-chaetiger stage. Polydora carinhosa sp. nov. exhibits lecithotrophy; larvae develop inside the capsules until the 14-chaetiger stage, then hatch and settle after a short planktonic stage. Newly settled individuals of all species construct a small silty tube on the shell surface before boring into the shell. Polydora ecuadoriana forms mud blisters on the inner side of oyster shells. Heavy infestation by this species poses a threat to oyster aquaculture in Brazil.

Authors: FUENTE GABRIEL D.L. , SKIRNISSON K. , DEHORITY BURK A.
Published: March 2024

Concentration and percentage generic and species composition were determined in rumen contents from five cows, five sheep, two goats and five reindeer living in Iceland. In general, total concentrations of ciliated protozoa in all species were similar to previously reported values. Concentrations of total protozoa ranged between 5.2 x 10 4 and 44.5 x 10 4 in the three domesticated species, as compared to a range of 130 x 10 4 – 250 x 10 4 in reindeer. Thirty-four species of protozoa plus 10 subspecies or forms were observed in Icelandic cattle, 27 species plus four forms were found in sheep, 13 species plus 2 forms in goats and 19 species in reindeer. Both Polyplastron and Ophryoscolex species were absent from all domestic animal species. However, this has been observed in a number of other geographical locations. The fauna present in reindeer was a typical rangifer-type fauna which is unique to that species and would further substantiate the occurrence of some host specificity in the genus Rangifer. It would appear that neither climate, nor isolation has markedly influenced protozoan populations in Iceland. . Key words: Cattle, ciliate protozoa, goats, Iceland, reindeer, rumen, sheep

Authors: COSTA WILSON J. E. M.
Published: March 2024

The seasonal plesiolebiasine killifish genera Pituna Costa, Plesiolebias Costa, and Maratecoara Costa, endemic to central and northeastern Brazil, are revised. A key is provided for the identification of plesiolebiasine genera, and keys are also included for species of the three revised genera. Six species are recognized in Pituna: P. brevirostrata n. sp. from the rio Paranaíba drainage, rio Paraná basin; P. poranga Costa from the rio Araguaia basin; P. compacta Myers from the rio Tocantins basin; P. schindleri n. sp. from the rio Parnaíba basin; P. obliquoseriata n. sp. from the rio das Mortes drainage; and P. xinguensis Costa & Nielsen n. sp. from the rio Xingu basin. Four new species of Plesiolebias are described, complementing a recent revision of the genus (Costa, 1998c): P. fragilis n. sp., from the middle rio Araguaia basin; P. altamira Costa & Nielsen n. sp., from the rio Xingu basin; P. filamentosus Costa & Brasil n. sp., from the rio Tocantins floodplains; and P. canabravensis Costa & Nielsen n. sp., from the rio Canabrava floodplains, rio Tocantins basin. Three species are recognized in Maratecoara: M. lacortei (Lazara), from the Araguaia–das Mortes basin; M. formosa Costa & Brasil, from the middle rio Tocantins floodplains; and M. splendida n. sp. from the rio Canabrava floodplains, rio Tocantins basin.

Authors: LI NA , REN BING-ZHONG
Published: March 2024

This study focuses on chromosomes and karyotypes of eight species of Tettigoniidae, which selected in Northeast China. And clustering analysis of these eight species was studied based on their chromosomal relative lengths for the first time. In the males, chromosome numbers vary from 2n = 31 (%) to 2n = 25 (%) and Fundamental Numbers (FN) from 32 to 28. All the species have the basic Orthopteran sex determining mechanism XX&/ X0%. The results of clustering analysis showed that the eight Tettigoniidae species form three well-supported groups when Rescaled Distance is 15, which include (1) the genus Gampsocleis and Metrioptera, (2) the genus Tettigonia and (3) the genus Paratlanticus. In particular, the morphology close species of G. sedakovii obscura and G. sedakovii sedkovii is strongly supported. The relationships among the eight species is as follows, (((G. sedakovii obscura, G. sedakovii sedkovii), G. ussuriensis), M. bonneti), ((T. cantans, T. ussuriana), T. caudata), P. tsushimensis.

The Persian/Arabian Gulf’s sole great white shark Carcharodon carcharias (Lamniformes: Lamnidae) record from Kuwait: misidentification of a sandtiger shark Carcharias taurus (Lamniformes: Odontaspididae)
Authors: MOORE ALEC B.M. , COMPAGNO LEONARD J.V. , FERGUSSON IAN K.
Published: March 2024

Records of the great white shark Carcharodon carcharias (Linnaeus) (Lamniformes: Lamnidae) in the Persian/Arabian Gulf (hereafter referred to as “The Gulf”) are limited to a single report from Kuwait, in the northwest Gulf, which has subsequently been noted in key references (e.g. Compagno, 2001). Khalaf (1987) recorded C. carcharias based on an observation of a mounted specimen in Kuwait Science and Natural History Museum on a visit there in March 1987. The specimen is reported as being a female C. carcharias of 3m in length, caught off Kuwait’s coast and supplied to the museum on the 14th of April 1984. A black and white photograph of the anterior portion (from just posterior of the pelvic fins) was included in Khalaf’s account (Fig. 1 here), but no measurements or morphological data were presented.

Mixturopoda Baker and Monson, a new genus of the uropodine family Metagynuridae (Acari: Mesostigmata) from the British Isles
Authors: BAKER ANNE S. , MONSON FRANK D.
Published: March 2024

A new taxon of mesostigmatid mite of the suborder Uropodina is described from damp, rotten straw associated with Dutch barns in NW England. Mixturopoda evansi gen. nov., sp. nov. possesses character states that have not previously been recorded in uropodines, e.g., the female genital shield bears setae st5 and is located behind coxae IV but not within the ventral shield, and barsitarsi II–IV lack seta pd3. Other states are a combination of those used to diagnose currently recognized superfamilies, e.g., subcylindrical, separated coxae I that are inserted in the gnathopodal cavity, absence of pedofossae and paragynial shields, and adult dorsal and marginal shields and deutonymphal dorsal shield undivided. Mixturopoda evansi is placed in the family Metagynuridae on the basis of the posterior position of the female genital shield. Amendments to the diagnoses of the Metagynuridae and its type genus, Metagynella, are proposed.
Liagore pulchella, a new species of xanthid crab (Crustacea: Decapoda: Brachyura) from Vanuatu
Authors: NG PETER K.L. , NARUSE TOHRU
Published: March 2024

Liagore pulchella, the third known species of the genus, is described from Vanuatu. The new species is easily recognizable from the two congeners by the complete absence of red spots on the dorsal surfaces of the carapace and the pereiopods. In addition, L. pulchella can be distinguished from L. rubromaculata (De Haan, 1835), and L. erythematica Guinot, 1971, by characters of the carapace, antenna, pereiopods and male first gonopod.

A new handfish, Brachionichthys australis sp. nov. (Lophiiformes: Brachionichthyidae), with a redescription of the critically endangered spotted handfish, B. hirsutus (Lacepède)
Authors: LAST PETER R. , GLEDHILL DANIEL C. , HOLMES BRONWYN H.
Published: March 2024

The micro-endemic Spotted Handfish, Brachionichthys hirsutus (Lacepède), which was discovered off Tasmania by the French explorer François Péron in the early 19 th century, is now endangered. A second spotted handfish of the genus Brachionichthys was first identified in the early 1980’s and is formally described based on material from southern Australia. Brachionichthys australis sp. nov. differs from its close congener B. hirsutus, in having a larger eye, longer illicium with a smaller esca, longer first dorsal-fin ray, fewer second dorsal-fin rays, shorter second dorsal-fin base, and a more subtle colour pattern. It also has a sparse covering of long, thin streaks and stripes (rather than small spots or short streaks), and the caudal fin is sparsely spotted (densely covered with fine spots that usually form a dark submarginal bar in B. hirsutus). They can also be distinguished using molecular analysis. Brachionichthys australis, which has a much wider geographic distribution and depth range than B. hirsutus, occurs mainly on the continental shelf of southern Australia from Bermagui (New South Wales) to the western sector of the Great Australian Bight (Western Australia), including eastern Tasmania south to the D’Entrecasteaux Channel, at depths of 18–210 m (and possibly to 277 m). Brachionichthys hirsutus, which is endemic to southeastern Tasmania where it was once common in bays and estuaries at depths of 1–60 m, is now considered by the IUCN to be critically endangered. These species, known in the vernacular as the spotted handfishes, are otherwise similar in appearance and may have been confused in the past.
Taxonomic revision of the seasonal South American killifish genus Simpsonichthys (Teleostei: Cyprinodontiformes: Aplocheiloidei: Rivulidae)
Authors: COSTA WILSON J.E.M.
Published: March 2024

Fifty species in five subgenera of Simpsonichthys (family Rivulidae) are recognized as valid. Xenurolebias, from the coastal plains of eastern Brazil, includes one species, S. myersi; Ophthalmolebias, from the coastal river basins of eastern and southeastern Brazil, comprises S. constanciae, S. suzarti, S. bokermanni, S. perpendicularis, and S. rosaceus; Simpsonichthys, from the central Brazilian plateau, in the upper Paraná, upper Araguaia and upper São Francisco river basins, comprises S. cholopteryx, S. parallelus, S. nigromaculatus, S. punctulatus, S. boitonei, S. santanae, and S. zonatus; Spectrolebias, from the Middle Tocantins, middle Araguaia, Xingu, Mamoré, and Paraguay river basins, in Brazil, Bolivia and Paraguay, includes S. reticulatus, S. costai, S. chacoensis, S. filamentosus, and S. semiocellatus; and Hypsolebias, from the São Francisco, Tocantins, Middle Jequitinhonha and lower Jaguaribe river basins and isolated coastal basins of northeastern Brazil, comprises S. ocellatus, S. rufus, S. stellatus, S. nielseni, S. notatus, S. radiosus, S. similis, S. gibberatus, S. virgulatus, S. trilineatus, S. auratus, S. hellneri, S. adornatus, S. fulminantis, S. carlettoi, S. magnificus, S. picturatus, S. antenori, S. macaubensis, S. mediopapillatus, S. ghisolfii, S. igneus, S. flavicaudatus, S. flagellatus, S. janaubensis, S. marginatus, S. delucai, S. alternatus, S. fasciatus, S. multiradiatus, S. flammeus, and S. brunoi.

Revision of the Alpheus formosus Gibbes, 1850 complex, with redescription of A. formosus and description of a new species from the tropical western Atlantic (Crustacea: Decapoda: Alpheidae)
Authors: ANKER ARTHUR , HURT CARLA , KNOWLTON NANCY
Published: March 2024

The Alpheus formosus Gibbes, 1850 complex is revised based on materials from the eastern Pacific and western Atlantic. Three species are recognized: Alpheus panamensis Kingsley, 1878 in the eastern Pacific, ranging from the Gulf of California to the Galapagos Archipelago; A. formosus Gibbes, 1850 (synonym: A. poeyi Guérin Méneville, 1857) in the western Atlantic, ranging from North Carolina and throughout the Caribbean to southern Brazil; and A. paraformosus n. sp., presently known only from the southwestern Caribbean (Panama) in the western Atlantic. Alpheus paraformosus n. sp. differs from A. formosus and A. panamensis by the distinctly shorter rostral furrows, the absence of balaeniceps setae on the fingers of the minor chela, and also several subtle but discrete features in the color pattern. Alpheus formosus is redescribed based on recently collected material. A female specimen from Florida Keys is designated as neotype of A. formosus. Morphology, color and genetics all suggest that A. formosus and A. panamensis are transisthmian sister species, with A. paraformosus n. sp. being their nearest relative.
A new species related to Alona costata Sars, 1862 (Cladocera: Anomopoda: Chydoridae) from South Africa
Authors: SINEV ARTEM YU
Published: March 2024

A new species of the genus Alona (Cladocera: Chydoridae), related to Alona costata Sars, 1862 was found in the Drakensberg Mountains, South Africa. Alona natalensis sp. n. differs from all other species of the costata-group by its unique carapace sculpturing. The position of the new species within the genus and its morphological peculiarities are discussed. A key for the world fauna of the costata-group is provided. A. natalensis sp. n. is confined to the Eastern Escarpment area; all occurrences are located within the area with an effective temperature index below 14 ºC. A complex of five endemic species of Anostraca (Hamer & Brendonk, 1997) as well as four recently described species of Chydoridae and Ilyocryptidae are confined to this area. Unlike widely distributed related species, A. natalensis sp. n. seems to be a relict species as defined by Korovchinsky (2006), confined to the restricted mountainous habitats.
