Three species of Dendrodorididae were collected from the intertidal zone of the northern coast of the Persian Gulf in Iran. Based on anatomical, histological, and molecular investigations they can be assigned to <em>Dendrodoris fumata</em>, <em>Dendrodoris nigra</em>, and a new species of <em>Doriopsilla</em>, <em>D.&nbsp;aroni</em> sp. nov. Molecular analyses of CO1 and 16S, including all genera of Dendrodorididae, members of the sister taxon Phyllidiidae, and other dorid outgroups resulted in a polyphyletic genus&nbsp;<em>Dendrodoris</em>, which is in contrast to the nuclear gene studies. Our&nbsp;molecular results&nbsp;confirm the differentiation between&nbsp;<em>Dendrodoris rubra</em>&nbsp;and&nbsp;<em>D. fumata</em>.&nbsp;<em>Dendrodoris nigra</em>,<em> D. fumata</em>, and <em>D.&nbsp;krusensternii</em>&nbsp;each consist&nbsp;of several clades,&nbsp;indicating&nbsp;cryptic species complexes&nbsp;requiring further investigation. We describe the presence of bacteria for the first time in the vestibular gland of <em>D.&nbsp;fumata</em>. Validation of the specimens of <em>Doriopsilla </em>from the Persian Gulf as a new species is supported by haplotype&nbsp;networking, genetic distance,&nbsp;and ABGD analyses of&nbsp;mitochondrial&nbsp;genes. Our CO1 analysis confirms a previous&nbsp;hypothesis that&nbsp;<em>Cariopsilla</em> is a junior synonym of&nbsp;<em>Doriopsilla.</em></p> Fatemeh Maniei, Heike Wägele Copyright (c) 2024 Fatemeh Maniei, Heike Wägele Tue, 09 Jul 2024 00:00:00 -0700 On the Neotropical species of the spider genus Tekellina Levi, 1957 (Arachnida: Araneae: Synotaxidae) <p>The genus<em> Tekellina</em> Levi, 1957 is currently composed of ten species, six of which are Neotropical. They are small-sized spiders (0.9 to 1.5&nbsp;mm), with a wide distribution, with a great diversity in the Neotropical Region and well represented in Brazil. In this article, males and females of the species <em>Tekellina bella </em>Marques &amp; Buckup, 1993 and <em>T.&nbsp;crica</em> Marques&nbsp;&amp; Buckup, 1993 are redescribed and illustrated. The female of <em>Tekellina minor </em>Marques &amp; Buckup, 1993 is described and illustrated for the first time. New records are included for Neotropical species. <em>Tekellina guaiba </em>Marques &amp; Buckup, 1993 is synonymized with <em>T.&nbsp;pretiosa</em> Marques &amp; Buckup, 1993. Three new species are described for Brazil: <em>Tekellina picurrucha </em>Rodrigues &amp; Estol sp. nov. (São Paulo, Paraná and Rio Grande do Sul), <em>Tekellina</em> <em>miuda</em> Rodrigues&nbsp;&amp; Estol sp.&nbsp;nov. (São Paulo and Paraná) and <em>Tekellina miudinha</em> Rodrigues &amp; Estol sp. nov. (São Paulo). Distribution maps with new records and an identification key of the Neotropical species are also presented.</p> Narelle Estol, Victor Hugo Valiati, Antonio D.

Nerillidae is the most species rich family among them, with 71&nbsp;species grouped into 15 genera, and represents an important component of the interstitial fauna, occupying a wide bathymetric range. Despite its problematic placement among the ‘Archiannelida’ families, the group per se is considered monophyletic. Currently, only two species of <em>Paranerilla</em> are valid, both being reported from the northern hemisphere. It is presented herein as the first description of a species of <em>Paranerilla</em> from tropical waters, named as <em>Paranerilla schiavettii </em>sp.&nbsp;nov., which is also considered as a unique record by the presence of a modified acicular spine in noto- and neuropodia from chaetiger 3–7, not mentioned in its congeners descriptions. Hence, we also propose an emendation on the genus diagnosis to embrace the presence of acicular spines within <em>Paranerilla</em>. So, the presented information complements the current knowledge about the group’s taxonomy and expands its distribution to South Atlantic waters.</p> Samuel Lucas da Silva Delgado Mendes, Jaqueline Carvalho Rodrigues, Alexandra E.

As a main objective, an updated key for the identification of all the genera of the world as they are established to date is provided and the incomplete knowledge of some of them is commented on. The insufficient knowledge of the diversity and geographic distribution of the six subfamilies of Lepismatidae is discussed, noting the most important shortcomings and problematic issues related to taxa belonging to this family, including the challenges for carrying out a comprehensive phylogeny of the group. Special attention is paid to the subfamily Ctenolepismatinae, the most diverse of Lepismatidae, erecting a new genus, <em>Caribesella</em> gen.&nbsp;nov., for the Caribbean species <em>C. impudica</em> comb.&nbsp;nov., which was previously included inside the genus <em>Acrotelsella</em>. We also consider that <em>Sceletolepisma</em> stat.&nbsp;nov. (i.e., sensu Irish 1987, including species with several median urosternal bristle-combs) deserves the status of a genus independent of <em>Ctenolepisma</em>, which, considered s. str. (i.e., lacking median urosternal combs), represents a heterogeneous group that requires further revision.</p> Rafael Molero-Baltanás, Miquel Gaju-Ricart, Graeme B.

The type species <em>D. verrucosa</em> Linnaeus, 1758 and a blueish and yellow morphotype of <em>D. ocelligera</em> collected in different localities in the Mediterranean Sea and the North-East Atlantic were sequenced, as well as <em>D. bertheloti</em> and the elusive <em>D. marmorata</em> for the first time. The genetic markers include the cytochrome <em>c</em> oxidase subunit I, 16S rRNA, and histone 3. The phylogenetic results suggest that the genus <em>Doris </em>is paraphyletic, and <em>D.&nbsp;ocelligera</em> morphotypes separate into two species, as confirmed with species delimitation tests. To complement the phylogenetic evidence with morphoanatomical data, the dissection of two specimens of each morphotype is conducted. Significant differences in morphological traits such as body shape, colouration patterns, and mantle tubercles come to light, together with anatomical differences in the relative shape and size of the radular teeth and reproductive structures. Considering the modern and old descriptions of <em>D. ocelligera</em>, it is finally concluded that the blueish morphotype belongs to <em>D.&nbsp;ocelligera</em>. In contrast, the yellow morphotype responds to the actual synonym <em>Aldisa berghi </em>(Vayssière, 1901), which is resurrected here as <em>Doris berghi </em>comb.&nbsp;rest. Considering the broad phylogeny of the family, some systematic notes at the genus level are here provided.</p> Mar F. Renau, Xavier Salvador, Juan Moles Copyright (c) 2024 Mar F.

Most species remain known from original taxonomic descriptions only, often insufficient for accurate identification. Therefore, the study of type specimens is critical to ensure proper identification. The Russian entomologist Viktor Ivanovich Motschulsky was one of the most important authors of firefly (Coleoptera: Lampyridae) taxonomy during the XIXth century, and his work is still relevant today. Part of his material, including the type specimens of several species, is deposited at the Zoological Institute of the Russian Academy of Sciences. Unlike their European, Asian, and Oceanian counterparts, the taxonomy of Neotropical fireflies is still in its infancy, partly due to largely outdated literature and difficulties in accessing type specimens. Here, we review the type specimens of 38&nbsp;firefly species deposited at ZIN, 15 of which are holotypes and 7 are lectotypes. For each specimen, the name-bearing status, condition of preservation, as well as the associated label data are provided. Lectotypes are designated for the following species described by Motschulsky: <em>Bicellonycha&nbsp;lividipennis</em>, <em>Ellychnia californica</em>, <em>Lychnuris klugii</em>, <em>Macrolampis&nbsp;longipennis</em>, <em>Pseudolychnuris&nbsp;suturalis</em>, <em>Telephoroides&nbsp;lineaticollis</em>, <em>Telephoroide&nbsp;occidentalis</em>.</p> William Lima, Alexey G.

Moseyko, Luiz Felipe Lima Da Silveira Wed, 26 Jun 2024 00:00:00 -0700 Seed morphology of the paleotropical tribe Paropsieae (Passifloraceae, Malpighiales), and paleobotanical implications <p>The fossil record of the diverse subfamily Passifloroideae (&gt;750 species and 17 genera) is relatively poor. Despite the distinctiveness of its leaves (glandular and often emarginate), most of the fossils from this group have been described from seeds. Fossil seeds have been recovered from Europe, and North and South America. A lack of information on seed morphology for all the genera and tribes of this subfamily has prevented a tribe-level identification of the fossils and a better understanding of their biogeographic patterns. The Passifloroideae is divided into three tribes: Passifloreae with 10 genera, Paropsieae with six genera and the monotypic Jongkindieae. This study provides new descriptions for 15 species from 5 genera from the mostly Afrotropical tribe Paropsieae based on herbarium material, and introduces an online seed database and a key for 100 species of Passifloroideae compiled from literature and direct observations. Our study shows a low morphological diversity among the seeds of Paropsieae in comparison to a much larger diversity within Passifloreae. Some rare morphologies are only present in Passifloreae and can be used to assign seeds to this tribe. Within the Paropsieae, <em>Androsiphonia</em> has seed that are very distinct from those in the other genera in the tribe and also from the rest of the subfamily. The genus <em>Paropsia</em> exhibits two main morphotypes, while the genera <em>Barteria</em>, <em>Paropsiopsis</em> and <em>Smeathmannia</em> have very similar seeds with a highly conserved morphology. These results suggest that living or fossil Paropsieae cannot be identified confidently based solely on seed characters.</p> Flavien Lagrange, Camila Martínez, Cédric Del Rio Copyright (c) 2024 Flavien Lagrange, Camila Martínez, Cédric Del Rio Tue, 25 Jun 2024 03:52:54 -0700 Twenty-one new species of the Neotropical rove beetle genus Neolindus Scheerpeltz (Coleoptera, Staphylinidae, Paederinae) <p>Rove beetles (Staphylinidae) are a diverse insect group, especially in the Neotropical region. At the same time, this fauna remains significantly understudied. During our visits to museum collections, we encountered numerous specimens of undescribed species representing the Neotropical genus <em>Neolindus </em>Scheerpeltz, 1933 which was earlier thought to be rare. To address the knowledge gap in the genus, we studied the museum material that resulted in descriptions of 21 new species. Our work involves the redescription of the genus, descriptions of the new species, and an updated identification key to 39 previously described and new species. The newly described species are <em>Neolindus bicornis</em> Guzman, Tokareva &amp; Żyła sp. nov.,<em> N.&nbsp;elegans </em>Guzman, Tokareva &amp; Żyła sp. nov.,<em> N.&nbsp;longithorax </em>Guzman, Tokareva &amp; Żyła sp. nov.,<em> N.&nbsp;luxipenis </em>Guzman, Tokareva &amp; Żyła sp. nov.,<em> N.&nbsp;maya </em>Guzman, Tokareva &amp; Żyła sp. nov.,<em> N.&nbsp;minutus </em>Guzman, Tokareva &amp; Żyła sp. nov.,<em> N.&nbsp;napo </em>Guzman, Tokareva &amp; Żyła sp. nov.,<em> N.&nbsp;niger </em>Guzman, Tokareva &amp; Żyła sp. nov.,<em> N.&nbsp;ornatus </em>Guzman, Tokareva &amp; Żyła sp. nov.,<em> N.&nbsp;parahermani </em>Guzman, Tokareva &amp; Żyła sp. nov.,<em> N.&nbsp;paraplectrus </em>Guzman, Tokareva &amp; Żyła sp. nov.,<em> N.&nbsp;parasinuatus </em>Guzman, Tokareva &amp; Żyła sp. nov.,<em> N.&nbsp;parautriensis </em>Guzman, Tokareva &amp; Żyła sp. nov.,<em> N.&nbsp;pseudosensillaris </em>Guzman, Tokareva &amp; Żyła sp. nov.,<em> N.&nbsp;sauron </em>Guzman, Tokareva &amp; Żyła sp. nov.,<em> N.&nbsp;sibyllae </em>Guzman, Tokareva &amp; Żyła sp. nov.,<em> N.&nbsp;triangularis</em> Guzman, Tokareva &amp; Żyła sp. nov.,<em> N.&nbsp;tropicalis </em>Guzman, Tokareva &amp; Żyła sp. nov.,<em> N.&nbsp;utriensis </em>Guzman, Tokareva &amp; Żyła sp. nov.,<em> N.&nbsp;volkeri </em>Guzman, Tokareva &amp; Żyła sp. nov., and<em> N.&nbsp;yotokae </em>Guzman, Tokareva &amp; Żyła sp. nov. This research emphasises the importance of museum collections in advancing taxonomy and enriching biodiversity knowledge. With these contributions, the known number of species of <em>Neolindus </em>reaches 60, thereby enhancing data on the Neotropical rove beetles diversity. Additionally, we provide several new country records for the genus (Guyana, Mexico, Nicaragua, and Suriname), which widen its distribution, and new occurrence records for the described species of <em>Neolindus</em>, <em>N.&nbsp;agilis </em>Herman, 1991; <em>N.&nbsp;apiculus</em> Herman, 1991; <em>N.&nbsp;basisinuatus</em> Herman, 1991; <em>N.&nbsp;campbelli </em>Herman, 1991; <em>N.&nbsp;cuneatus</em> Herman, 1991; <em>N.&nbsp;hermani </em>Asenjo, 2011; <em>N.&nbsp;irmleri </em>Asenjo, 2011; <em>N.&nbsp;lodhii</em> Herman, 1991; <em>N.&nbsp;procarinatus</em> Herman, 1991; <em>N.&nbsp;punctogularis </em>Herman, 1991; and <em>N.&nbsp;retusus</em> Herman, 1991.</p> Yoan Camilo Guzman, Alexandra Tokareva, Katarzyna Koszela, Dagmara Żyła Copyright (c) 2024 Yoan Camilo Guzman, Alexandra Tokareva, Katarzyna Koszela, Dagmara Żyła Mon, 24 Jun 2024 00:18:10 -0700
