During the 19<sup>th</sup> and 20<sup>th</sup> centuries, the family placement of this genus became controversial as the set of morphological features present in <em>Gyrophyllum</em> could justify its assignation to both the families Pennatulidae Ehrenberg, 1834 and Pteroeididae Kölliker, 1880. Deliberations over this intermediate set of characters finally ended in the reunification of the genera and species of both families under Pennatulidae by principle of priority. The use of molecular sources of information based on a series of sequencing techniques presents a different but promising phylogenetic scenario in order to go further in the understanding of pennatulacean systematics. In this paper, a complementary morphological and molecular study (multiloci sequences with three mitochondrial and one nuclear markers) based mainly on newly collected material is carried out. This study re-confirms from a molecular point of view previously published results that indicate the position of <em>Gyrophyllum</em> as being distant from <em>Pennatula</em> Linnaeus, 1758 and <em>Pteroeides</em> Herklots, 1858 (type genera of the families Pennatulidae and Pteroeididae, respectively). This fact together with the results of a detailed morphological examination strongly supports the placement of the enigmatic genus <em>Gyrophyllum</em> in a separate family: Gyrophyllidae fam.&nbsp;nov. and resolves the nomenclatural uncertainty at family level for this genus. Moreover, the characters previously considered useful in the distinction of the two currently recognised species <em>G.&nbsp;hirondellei</em> in the Atlantic and <em>G.&nbsp;sibogae</em> Hickson, 1916 in the Indo-western Pacific are revisited.</p> Pablo J.

We examined barcodes for evidence of species’ gene coalescents within this species complex, using the closely related <em>vagans</em>-group to help calibrate Poisson-tree-process models to a level of branching appropriate for discovering species. The results support seven candidate species within the <em>hypnorum</em>-complex (<em>Bombus taiwanensis</em> Williams, Sung, Lin &amp; Lu, 2022, <em>B.&nbsp;wolongensis</em> Williams, Ren &amp; Xie sp.&nbsp;nov., <em>B.&nbsp;bryorum </em>Richards, 1930, <em>B.&nbsp;hypnorum</em>, <em>B.&nbsp;koropokkrus</em> Sakagami &amp; Ishikawa, 1972, and <em>B.&nbsp;hengduanensis</em> Williams, Ren &amp; Xie sp.&nbsp;nov., plus <em>B.&nbsp;perplexus</em>), which are comparable in status to the currently accepted species of the <em>vagans</em>-group. Morphological corroboration of the coalescent candidate species is subtle but supports the gene coalescents if these candidates are considered near-cryptic species.</p> Paul H.

Their male first gonopods are also different from each other. Counting <em>Gurumon gurumayum </em>gen. et sp.&nbsp;nov., India is currently known for ten genera and 24&nbsp;species of potamiscine freshwater crabs, and Arunachal Pradesh for eight genera and 11&nbsp;species of these crabs. The current nomenclatural problems with <em>Potamiscus</em> are also discussed.</p> Sameer K. Pati Copyright (c) 2022 Sameer K.

All the new species are described and illustrated based on females, and partial mitochondrial cytochrome oxidase subunit I (<em>COI</em>) sequences are provided for the six new species as well as for the previously described <em>Z. fumosa </em>Peng &amp; Xiang. Females of all the species of <em>Zaischnopsis </em>recorded from China are differentiated in a key.</p> Hao Tang, Jingtao Jiang, Tong Wu, Jun Deng, Lingfei Peng Copyright (c) 2022 Hao Tang, Jingtao Jiang, Tong Wu, Jun Deng, Lingfei Peng Wed, 16 Nov 2022 00:05:39 -0800 Revision of the Neotropical species of Pareucamptonyx Olmi (Hymenoptera, Dryinidae) with descriptions of new species <p>The genus <em>Pareucamptonyx</em> Olmi, 1991 is endemic to the New World and comprises three described species, two from the Neotropical region and one from the Nearctic. Here is presented the first revision of species of <em>Pareucamptonyx</em> from the Neotropical region, including four new species described from Brazil: <em>P. albopictus</em> Martins sp. nov., <em>P. kumagaiae</em> Martins sp. nov., <em>P. niger</em> Martins sp. nov. and <em>P. paranaensis</em> Martins sp. nov. Detailed illustrations, distribution map, and key to females are provided, as well as a revised diagnosis of the genus and notes about the method of collection. Additionally, new distribution records for <em>P. townesi</em> (Olmi, 1984) are reported.</p> André L. Martins, Alexandre C. Domahovski Copyright (c) 2022 André L. Martins, Alexandre C.

We also report the morphological variation of females and males of <em>H.&nbsp;mexicanus </em>Zaldívar-Riverón &amp; Belokobylskij, 2009, originally described based on a single female, and provide its first precise geographical distribution records. An updated key to the 13 described species of <em>Hecabolus</em> is provided.</p> Rubén Castañeda-Osorio, Sergey A.

Skevington Mon, 07 Nov 2022 00:00:46 -0800 Revision of the tribe Pogonini (Coleoptera, Carabidae, Trechinae) from the Ibero-Balearic region <p>In the Iberian Peninsula and the Balearic Islands, Pogonini (Coleoptera, Carabidae) is the least species-rich tribe of Trechinae. Nevertheless, the taxon is relatively poorly studied in this territory, and the available records are mostly published in old and/or faunistic works. The present study provides a taxonomic revision of the 3 genera and 11 species of Pogonini occurring in the Ibero-Balearic region, with an identification key, diagnoses and illustrations of their external morphology and aedeagus. The chorology of the species was also studied, and was assessed by obtaining precise records from published papers and the collection localities of the examined material. These data were used to make updated distribution maps (with several new occurrence points) that reveal a strong regionalization of the tribe in the Ibero-Balearic territory. The species occur in humid and saline environments, especially along the meridional and Mediterranean coasts of the Iberian Peninsula and in inner arid localities of eastern Spain. This result agrees with the widely accepted halobiont condition of the group. However, sampling bias must be considered, and new records are expected to be provided from future revisions of collections and new samplings.</p> José Muñoz-Santiago, Vicente M.

Its generic characters (absence of cephalic peaks, ventrally inserted lateral antennae, reduced notopodium and chaetae all stout) place it close to <em>Antinoe</em> Kinberg, 1856, <em>Hermadion</em> Kinberg, 1856 and <em>Malmgrenia</em> McIntosh, 1874, but the combination is unique and justifies the erection of a new genus. The new genus and species are described, figured and discussed in detail. An updated list of taxa and an identification key to all genera of Polynoinae Kinberg, 1856 sensu lato currently reported from the extended Northeast Atlantic are given.</p> Jorge Núñez, Ruth Barnich, Óscar Monterroso Copyright (c) 2022 Jorge Núñez, Ruth Barnich, Óscar Monterroso Tue, 01 Nov 2022 03:09:32 -0700 Revision of the genera Pseudotraulia Laosinchai & Jago, 1980 and Bannacris Zheng, 1980 (Orthoptera: Acrididae) with proposal of new synonyms <p>The genera <em>Pseudotraulia</em> Laosinchai &amp; Jago, 1980 and <em>Bannacris</em> Zheng, 1980 are revised based on the examination of types and additional materials. <em>Bannacris punctonotus </em>Zheng, 1980 is synonymized with <em>Pseudotraulia cornuata</em> Laosinchai &amp; Jago, 1980 and <em>Bannacris</em> Zheng, 1980 with <em>Pseudotraulia</em> Laosinchai &amp; Jago, 1980. The tribal placement of <em>Pseudotraulia</em> is discussed and the genus <em>Pseudotraulia</em> is transferred here from the tribe Mesambriini of the subfamily Catantopinae Brunner von Wattenwyl, 1893 to the subfamily Coptacrinae Brunner von Wattenwyl, 1893 which is not divided into tribes and consists of 22 genera distributed in the Afrotropical and Oriental regions.</p> Sergey Yu.
