A total of nine species are confirmed from the continent, of which <em>T.&nbsp;tuberculifer</em> Onuferko, Rightmyer &amp; Roig-Alsina &nbsp;sp. nov. is newly described. Four new synonymies are proposed: <em>T.&nbsp;aguilari</em> Moure, 1955 syn. nov. and <em>T.&nbsp;megadelphus</em> Cockerell, 1914 syn. nov. under <em>T.&nbsp;buchwaldi</em> (Friese, 1908); <em>T. bilineatus</em> Cockerell, 1949 syn. nov. under <em>T.&nbsp;flavipennis</em> (Friese, 1916); and <em>Epeolus merus</em> Brèthes, 1909 syn. nov. under <em>T.&nbsp;nemoralis</em> (Holmberg, 1886). Males of <em>T.&nbsp;alvarengai</em> Moure, 1955 and <em>T.&nbsp;rufotegularis</em> (Ashmead, 1900) and females of <em>T.&nbsp;atoconganus</em> Moure, 1955 and <em>T.&nbsp;cecilyae</em> Packer, 2016 are described for the first time.&nbsp;Lectotypes are designated for the following (all originally described under <em>Epeolus</em> Latreille, 1802 but now recognized as <em>Triepeolus</em>): <em>E.&nbsp;buchwaldi</em>, <em>E.&nbsp;flavipennis</em>, <em>E.&nbsp;osiriformis</em> Schrottky, 1910 and its junior synonym <em>E.&nbsp;luteipes</em> Friese, 1916, and <em>E.&nbsp;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> Thomas M. Onuferko, Molly G. Rightmyer, Gabriel A.R.

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.&nbsp;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> 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.&nbsp;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.&nbsp;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> Sukonthip Savatenalinton Copyright (c) 2024 Sukonthip Savatenalinton https://creativecommons.org/licenses/by/4.0 https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/2499 Fri, 12 Apr 2024 00:41:54 -0700 Jambu, a new genus of tarantula from Brazil (Araneae, Theraphosidae, Theraphosinae) https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/2497 <p>The genus <em>Jambu</em> gen.&nbsp;nov. is proposed based on two new species:<em> Jambu paru</em> gen. et sp.&nbsp;nov. and <em>Jambu manoa</em> gen. et sp.&nbsp;nov. <em>Hapalopus butantan</em> is transferred to <em>Jambu</em>; consequently, <em>Jambu butantan</em> gen. et comb.&nbsp;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> Laura T. Miglio, Carlos Perafán, Fernando Pérez-Miles Copyright (c) 2024 Laura T.

Mexico houses nearly 16% of the total genera and most are endemic, inhabiting threatened native forests. Here, a new unusual Mexican genus, <em>Christopherus </em>gen. nov., is described to accommodate a new species of Cicadellini, <em>C. mictlantecuhtli</em> sp. nov., collected in the endangered Cloud Forest of Sierra Juárez, Oaxaca State of Mexico, based on dry-pinned museum specimen data. The new taxa can be separated from other Neotropical Cicadellini genera easily using male genitalia features: (i) pygofer without processes, (ii)&nbsp;segment 10<sup>th</sup> without processes, (iii) paraphysis absent, and (iv) edeagus with single basal atrial process elongate and asymmetrical. The monotypic genus <em>Gillonella </em>with its type species,<em> G. ampulla</em> Nielson &amp; Godoy, 1995, are redescribed. A detailed extensive morphological description and discussion to distinguish the new genus from allied red-striped Neotropical genera in Mexico, Central America, and South America are given. Distributional data for new taxa within Mexican forests is also provided.</p> Jorge Adilson Pinedo-Escatel, Edith Blanco-Rodríguez Copyright (c) 2024 Jorge Adilson Pinedo-Escatel, Edith Blanco-Rodríguez https://creativecommons.org/licenses/by/4.0 https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/2495 Thu, 04 Apr 2024 00:00:00 -0700 Updating the morphological phylogenetics of Nopinae (Araneae: Caponiidae): novel terminals and characters, with two new species https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/2493 <p>A re-analysis of the morphological phylogeny of the Nopinae is made, based on an update in the description of <em>Aamunops</em> Galán-Sánchez&nbsp;&amp; Álvarez-Padilla, 2022 and the addition of the recently described genera <em>Nopsma</em> Sánchez-Ruiz, Brescovit &amp; Bonaldo, 2020 and <em>Roddemberryus</em> Sánchez-Ruiz &amp; Bonaldo, 2023. Two new species, <em>Aamunops hoof</em> sp.&nbsp;nov. (male) and <em>Aamunops yiselae</em> sp.&nbsp;nov. (male and female), are also described, which allows a better understanding of the genus morphology and resulted in an emended diagnosis. The description of <em>Aamunops</em> has been updated to include several characteristics of the ultrastructural morphology, legs, chelicerae, palps and female genitalia. The inclusion of these new characters of <em>Aamunops</em> along with those of <em>Nopsma</em> and <em>Roddemberryus</em> in the previous data matrix resulted in a new, completely different hypothesis of the relationships of the nopine genera: <em>Nopsma</em> is part of a group formed by <em>Cubanops</em> and <em>Nyetnops</em>, while <em>Aamunops</em> and <em>Roddemberryus</em> are grouped with representatives of <em>Tarsonops</em>. The four-eyed <em>Nopsides ceralbonus</em> Chamberlin, 1924 was recovered as the most basal species of Nopinae. The relationships among genera of Nopinae and the phylogenetic position of three species, whose taxonomic position is doubtful (<em>Cubanops luquillo</em> Sánchez-Ruiz, Brescovit &amp; Alayón, 2015, <em>Orthonops confuso</em> Galán-Sánchez &amp; Álvarez-Padilla, 2022 and <em>Tarsonops irataylori</em> Bond &amp; Taylor, 2013), is also discussed.</p> Alexander Sánchez-Ruiz, Alexandre B.
