<p lang="en-GB" align="left"><span style="color: #000000;"><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">The aim of this study was to provide a commented catalogue of the snapping shrimp species belonging to the genus <em>Synalpheus </em>Spence Bate, 1888 from Northeast Brazil region, a 3,300 kilometers long tropical coast. The material examined was collected from various sites along the coast of the state of Pernambuco, as well as from the archipelagos of Fernando de Noronha and São Pedro e São Paulo. Additionally, specimens deposited in the crustacean collection of the Museu de Oceanografia Prof. Petrônio Alves Coelho (MOUFPE) were also examined. A total of 1010 individuals belonging to 26 species were analyzed. This study provides six new records for the southwestern Atlantic [<em>Synalpheus</em> <em>barahonensis </em>Armstrong, 1949, <em>S</em>. <em>belizensis </em>Anker & Tóth, 2008, <em>S</em>. <em>brevidactylus </em>Anker & Tóth, 2008, <em>S</em>. <em>corallinus </em>Macdonald, Hultgren & Duffy, 2009, <em>S</em>. <em>hoetjesi </em>Hultgren, Macdonald & Duffy, 2010, and<em> S</em>. <em>kensleyi </em>(Ríos & Duffy, 2007)] and 13 range extensions/new records [(<em>S</em>. <em>agelas </em>Pequegnat & Heard, 1979, <em>S</em>. <em>androsi </em>Coutière, 1909, <em>S</em>. <em>antillensis </em>Coutière, 1909, <em>S</em>. <em>dardeaui </em>(Ríos & Duffy, 2007), <em>S</em>. <em>fritzmuelleri </em>Coutière, 1909, <em>S</em>. <em>hemphilli </em>Coutière, 1909,<em> S. herricki</em> Coutière, 1909, <em>S</em>. <em>pandionis </em>Coutière, 1909, <em>S</em>. <em>ruetzleri </em>Macdonald & Duffy, 2006, <em>S</em>. <em>tenuispina </em>Coutière, 1909, <em>S</em>. <em>townsendi</em> Coutière, 1909, <em>S. ubatuba</em> Mantelatto, França, Cunha & Almeida, 2023, and <em>S</em>. <em>yano </em>(Ríos & Duffy, 2007)]) along the Brazilian coast. Some of these records were confirmed using molecular data (ribosomal 16S gene). Moreover, comments regarding doubtful records in the study area (<em>S</em>. <em>filidigitus </em>Armstrong, 1949, <em>S</em>. <em>longicarpus </em>(Herrick, 1891), <em>S</em>. <em>paraneptunus </em>Coutière, 1909, and <em>S.</em> <em>rathbunae </em>Coutière, 1909) are also provided. Taking into account the exclusion of the doubtful records, our data increases from 27 to 29, and from 29 to 31 species, recorded in the study area and along the Brazilian coast, respectively.</span></span></span></p> <p> </p>PEDRO HENRIQUE PAIXÃOMARIANA TEROSSIKARMINE PASINATTOGABRIEL LUCAS BOCHINIALEXANDRE OLIVEIRA ALMEIDA

https://mapress.com/zt/article/view/zootaxa.5666.1.3
<p lang="en-GB" align="left"><span style="color: #000000;"><span style="font-family: Times New Roman, serif;"><span style="font-size: small;"><em>Athis</em> Hübner, [1819] is the most diverse genus of diurnal moths of the family Castniidae distributed in America. Little is known about the biology and distribution of most species. Based on an exhaustive review of entomological collections and field work, we provide information on the ecology, behavior, distribution and variability of two rare and little-known species: <em>A. delecta</em> (Schaus, 1911) and <em>A. jaliscana</em> López-Godínez & Porion, 2012. We also illustrate for the first time the wing venation and male genitalia for both species. <em>Athis delecta</em> is reported for the first time in the Mexican state of Puebla. Findings in the field suggest that these two species have an atypical average flight height for Castniidae, being recorded between four and ten meters above the ground. Furthermore, since previous comparisons between <em>Athis delecta</em> and <em>A. jaliscana</em> were based solely on wing pattern, we conducted a geometric morphometric analysis to evaluate and illustrate potential differences in wing shape between males of both species. The present work expands the knowledge about the biology of the family and demonstrates that geometric morphometrics is an appropriate tool for future taxonomic studies of Castniidae.</span></span></span></p> <p> </p>JOSÉ DE JESÚS GARCÍA-DÍAZANDRÉS RAMÍREZ-PONCEBERNARDO LÓPEZ-GODÍNEZELIER TORRES-YAÑEZ

https://mapress.com/zt/article/view/zootaxa.5666.1.6
<p lang="en-GB" align="left"><span style="color: #000000;"><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">Larvae of the soft-bodied click-beetle tribe Drilini are obligatory predators of land snails. Larval stages are known only for several species from the West Palaearctic region and two species from the tropical Africa. In this study, for the first time we describe and illustrate the active larva of Drilini from the Oriental realm based on a single specimen from the western India. It is putatively identified as <em>Selasia</em> sp. as this is the only genus of Drilini known from the Indian subcontinent. We compare the Indian larva with other known active larvae of Drilini and add <em>Tanychlamys</em> sp. (Helicarionoidea: Ariophantidae) to the list of prey for the Drilini larvae. We would like to use this opportunity to encourage colleagues to share with us data on Drilini larvae and their prey from India to better understand their predator-prey interactions.</span></span></span></p> <p> </p>HARSHAD PAREKARSIMONE POLICENA ROSAGABRIELA PACKOVAAMOL PATWARDHANROBIN KUNDRATA

<p lang="en-GB" align="left"><span style="color: #000000;"><span style="font-family: Times New Roman, serif;"><span style="font-size: small;">A new species of <em>Phyllodonta</em> is described and illustrated from Mexico: <em>P. coztomatlivora</em> <strong>sp. nov.</strong> The new species is superficially indistinguishable from others in the so-called latrata species group, from which three other cryptic species from Costa Rica were recently described. However, it differs from them in features of the female genitalia, caterpillar morphology, larval food plant choice and DNA barcode. The new entity may be restricted to high elevations of the Trans Mexican Volcanic Belt; in Mexico City, the species is found inside a protected natural area which should warrant some level of conservation. </span></span></span></p> <p> </p>IVONNE J.
