Conchafrancisco.concha@uv.cl<p>Angel sharks (<em>Squatina</em> spp. Duméril, 1805) are a group of coastal benthic sharks distributed worldwide, currently including threatened and understudied species. Two species are formally described along the East Pacific coast, the California angel shark <em>S. californica</em> Ayres, 1859 and the Chilean angel shark <em>S. armata</em> (Philippi, 1887). The latter species occurs in the southeastern Pacific and has historically been understudied. Additionally, the original description of <em>S. armata</em> lacks sufficient data to confidently identify individuals of this species compared to modern descriptions, and no type specimen is currently available to ensure specimen identification. Detailed morphological descriptions for identifying species are an essential resource for solving taxonomic issues in groups of morphologically similar species and to promote the conservation of critically endangered species. Therefore, a neotype from the type locality is here designated for <em>S. armata</em>, and a detailed and standardized morphological characterization based on modern taxonomic works is provided. This work contributes in improving the knowledge on the Chilean angel shark taxonomy and provides an improved frame of reference for identifying angel sharks in the East Pacific, especially in areas where species may occur in sympatry.</p>2024-04-25T00:00:00-07:00Copyright (c) 2024 Sebastián Kraft, Ítalo Fernández-Cisternas, Miguel Araya, Francisco J.

The genus has six species and is characterized by the distinct ‘zebra’ pattern displayed by some of them. The species are recorded in French Guiana, Peru, and Colombia. Here, we describe two new species of the genus from the Brazilian Amazon rainforest, the first record of the genus for Brazil. We expand the records of <em>Z. guianensis </em>Desutter-Grandcolas, 2014 and <em>Z. nouragui </em>Desutter-Grandcolas, 2014 to Brazil. We also describe but do not name two females corresponding to two new species, provide an up-to-date key for species of <em>Zebragryllus</em>, and discuss the potential distribution for the genus.</p>2024-04-24T01:31:33-07:00Copyright (c) 2024 Gustavo Costa Tavares, Beatriz Harumi Kondo Oya, Oscar J.

Windeckerclaire.windecker@humboldt.eduSean Craigsean.craig@humboldt.edu<p>Seven species of the cheilostome bryozoan genus <em>Microporella </em>were identified across 15 rocky intertidal sites spanning 940 km of the California coast, from Mill Creek in the Montereyan Pacific Transition Region north to Point Saint George in the Mendocinian Region. Colonies of <em>Microporella</em> were found encrusting boulders and mollusc shells. Among these species, three are new to science, namely <em>Microporella dentata </em>Chowdhury & Di Martino sp. nov., <em>M. pauciperforata</em> Chowdhury & Di Martino sp. nov. and <em>M. rota </em>Chowdhury & Di Martino sp. nov. Three other species, <em>M. californica</em>, <em>M. setiformis</em>, and <em>M. umbonata</em> have previously been recorded from other localities in California. Finally, <em>Microporella neocribroides</em>, originally described from off Kodiak Island, Alaska, and subsequently found in Hokkaido, Japan, was recorded in California for the first time. An additional new species, <em>M. similis </em>Chowdhury & Di Martino sp. nov., was identified through the re-examination of museum material previously attributed to <em>M. cribrosa</em> and <em>M. californica</em>. These newly acquired data allowed for a more comprehensive examination of the distribution of species, intraspecific variability, and potential predator-induced teratologies in certain species, thanks to the availability of numerous colonies from various sites and the re-examination of museum records. Altogether, this study increases the known Recent diversity of <em>Microporella</em> in California’s waters to a total of 18 species.</p>2024-04-22T00:12:03-07:00Copyright (c) 2024 Ismael A.

Melogarmelo@ufpr.brArturo Roig-Alsinaarturo@macn.gov.ar<p>The cleptoparasitic bee genus <em>Triepeolus</em> Robertson, 1901 (Hymenoptera: Apidae) is revised for species occurring in South America. A total of nine species are confirmed from the continent, of which <em>T. tuberculifer</em> Onuferko, Rightmyer & Roig-Alsina sp. nov. is newly described. Four new synonymies are proposed: <em>T. aguilari</em> Moure, 1955 syn. nov. and <em>T. megadelphus</em> Cockerell, 1914 syn. nov. under <em>T. buchwaldi</em> (Friese, 1908); <em>T. bilineatus</em> Cockerell, 1949 syn. nov. under <em>T. flavipennis</em> (Friese, 1916); and <em>Epeolus merus</em> Brèthes, 1909 syn. nov. under <em>T. nemoralis</em> (Holmberg, 1886). Males of <em>T. alvarengai</em> Moure, 1955 and <em>T. rufotegularis</em> (Ashmead, 1900) and females of <em>T. atoconganus</em> Moure, 1955 and <em>T. cecilyae</em> Packer, 2016 are described for the first time. Lectotypes are designated for the following (all originally described under <em>Epeolus</em> Latreille, 1802 but now recognized as <em>Triepeolus</em>): <em>E. buchwaldi</em>, <em>E. flavipennis</em>, <em>E. osiriformis</em> Schrottky, 1910 and its junior synonym <em>E. luteipes</em> Friese, 1916, and <em>E. rufotegularis</em>. Diagnoses and complete descriptions/redescriptions are provided for all species, along with a fully illustrated dichotomous identification key (with Portuguese and Spanish versions available as supplementary material) to distinguish them based on external morphological features. Additionally, known collection records and information about the ecology of the treated species are presented.</p>2024-04-17T01:05:25-07:00Copyright (c) 2024 Thomas M. Onuferko, Molly G.

Cuestajose.cuesta@icman.csic.es<p>The use of integrative taxonomy has confirmed the existence of a new distinct crab species, cryptic, within the group of the former genus <em>Liocarcinus</em>, now <em>Polybius</em>, closely related to <em>P. holsatus</em>, <em>P. vernalis</em> and <em>P. marmoreus.</em> Previous reports have considered it to be the Atlantic form of <em>P. vernalis</em>, or as a species “affinis” or “comparable to” <em>P. holsatus</em>. Diagnostic morphological characters are presented for identification and the morphological variability in these species, mainly within <em>P. vernalis</em> (the most related) is analysed. Furthermore, based on molecular and other previous data, a new combination (genus change) is proposed. This new species, <em>Polybius dioscurus</em> sp. nov., lives on infralittoral sandy bottoms, coexisting with the other species mentioned, in the temperate and subtropical zone of the North Atlantic Ocean, including the Alboran Sea (westernmost Mediterranean).</p>2024-04-15T00:00:00-07:00Copyright (c) 2024 Enrique García-Raso, Cédric d’Udekem d’Acoz, Abdellatif Moukrim, Christoph D.

The new species can be distinguished primarily by a considerably small anterior overlap of the left valve over the right valve (RV), a postero-ventral flange of the RV, a remarkably large claw Ga of the CR and the chaetotaxy of the limbs, especially A1, Md-palp and T2. In addition, in the present study, the sexual population of <em>S. martensi</em> Savatenalinton, 2015 is recorded for the first time, and thus the first description of the male is provided here. Moreover, the morphological examination of both males and females revealed differences between asexual and sexual females and also points to the fact that <em>S. martensi</em> is a mixed reproduction species. This is the first record of the mixed reproductive mode in the genus <em>Strandesia</em> or even in the Cypricercinae.</p>2024-04-12T00:41:54-07:00Copyright (c) 2024 Sukonthip Savatenalintonhttps://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/2497Jambu, a new genus of tarantula from Brazil (Araneae, Theraphosidae, Theraphosinae)2024-04-05T15:46:15-07:00Laura T. Migliolauramiglio@gmail.comCarlos Perafáncaperafanl@gmail.comFernando Pérez-Milesmyga@fcien.edu.uy<p>The genus <em>Jambu</em> gen. nov. is proposed based on two new species:<em> Jambu paru</em> gen. et sp. nov. and <em>Jambu manoa</em> gen. et sp. nov. <em>Hapalopus butantan</em> is transferred to <em>Jambu</em>; consequently, <em>Jambu butantan</em> gen. et comb. nov. is proposed. The geographic distribution of<em> J. butantan</em> is extended on the basis of new material collected. The new genus and the new species are here diagnosed, described and illustrated. The shape of the genitalia of <em>Jambu</em> resembles that of Hapalopini but differs from most of them by the presence of type IV urticating setae. The presence of this type of urticating setae allows us to hypothesize that this new genus is phylogenetically related with Grammostolini. Males of <em>Jambu</em> differ from those of other genera of Grammostolini by the presence of a paraembolic apophysis on the palpal bulb. Females also differ from those of other Grammostolini by the spermathecae morphology, with one medial lamp-shaped or heart-shaped receptacle. The homology of some features and the taxonomic placement of the new genus are discussed.</p>2024-04-05T00:00:00-07:00Copyright (c) 2024 Laura T. Miglio, Carlos Perafán, Fernando Pérez-Miles
