Species often have vivid colourations which make them charismatic photograph subjects among macro photographers. However, their taxonomy has not been revised since their original descriptions, whereas there are also species awaiting to be discovered and described. A synoptic revision is therefore needed prior to studying the phylogenetic relationships of the genus, and before undertaking more precise studies on biogeography and evolution of traits. By holistically incorporating information about general morphology, male and female genitalia, and bioacoustics, we revise the taxonomy of these crickets and recognise 10 valid species of <em>Nisitrus</em>. Five new species are described: <em>N.&nbsp;crucius</em> Robillard &amp; Tan sp. nov. from Borneo; <em>N.&nbsp;danum</em> Robillard &amp; Tan sp. nov. from Borneo; <em>N.&nbsp;hughtani</em> Robillard &amp; Tan sp. nov. from Sumatra; <em>N.&nbsp;malaya</em> Robillard &amp; Tan sp. nov. from Malay Peninsula; and <em>N.&nbsp;rindu</em> Robillard &amp; Tan sp. nov. from Borneo. We redescribe <em>N.&nbsp;brunnerianus</em> and <em>N.&nbsp;insignis</em>; describe the calls of <em>N.&nbsp;malaya</em> sp.&nbsp;nov., <em>N.&nbsp;musicus</em> and <em>N.&nbsp;vittatus</em>. We consider <em>N.&nbsp;sumatrensis</em> as a junior synonym of <em>N.&nbsp;insignis</em>; and <em>N.&nbsp;marginata</em> as a junior synonym of <em>N.&nbsp;vittatus</em>. <em>Nisitrus hyalinus</em> requires further revision. We also consider <em>N.&nbsp;maculosus</em> as a dubious name.</p> Ming Kai Tan, Rodzay bin Haji Abdul Wahab, Razy Japir, Authur Y.C.

(Annelida, Nereididae), a remarkable new annelid species living inside deep-sea polymetallic nodules https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/1447 <p>A new species of abyssal <em>Neanthes </em>Kinberg, 1865, <em>N. goodayi </em>sp. nov., is described from the Clarion-Clipperton Zone in the central Pacific Ocean, a region targeted for seabed mineral exploration for polymetallic nodules. It is a relatively large animal found living inside polymetallic nodules and in xenophyophores (giant Foraminifera) growing on nodules, highlighting the importance of the mineral resource itself as a distinct microhabitat. <em>Neanthes goodayi </em>sp. nov. can be distinguished from its congeners primarily by its distinctive, enlarged anterior pair of eyes in addition to characters of the head, pharynx and parapodia. Widespread, abundant, and easily recognisable, <em>N. goodayi </em>sp. nov. is also considered to be a suitable candidate as a potential indicator taxon for future monitoring of the impacts of seabed mining.</p> Regan Drennan, Helena Wiklund, Muriel Rabone, Magdalena N.

We name the new species <em>Potamites hydroimperator</em> sp.&nbsp;nov. because it is the only lizard living in streams in this isolated mountain. The new species is distinguishable from other congeners (except <em>P.&nbsp;ecpleopus</em>) by having longitudinal rows of keeled scales on dorsum, and males with 5–8 lateral ocelli on each flank. <em>Potamites hydroimperator</em> sp.&nbsp;nov. differs from <em>P.&nbsp;ecpleopus</em> by being smaller, having dorsal scales on forelimbs smooth or slightly keeled, subconical tubercles on forelimbs weakly present or absent, and four to five superciliar scales. We comment on variation in the pattern of keeling of dorsal scales among Amazonian lowland, Andean foothills and montane species of <em>Potamites</em>, and the potential relevance of this scalation pattern for taxonomic and biogeographic studies. The new species increases our knowledge of the diverse and endemic herpetofauna of El Sira, and of diversity within the genus <em>Potamites</em>. Despite El Sira’s status as natural protected area, gold mining activities are destroying the streams where we found <em>P.&nbsp;hydroimperator</em> sp.&nbsp;nov., threatening their populations.</p> Germán Chávez, Jose Malqui, Alessandro Catenazzi Copyright (c) 2021 Germán Chávez, Jose Malqui, Alessandro Catenazzi https://creativecommons.org/licenses/by/4.0 https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/1445 Fri, 23 Jul 2021 00:41:44 -0700 Redescriptions of Neanthes Kinberg, 1865 (Annelida: Errantia: Nereididae) species from worldwide regions https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/1443 <p>The present study redescribes four species of <em>Neanthes</em> Kinberg, 1865 (Nereididae de Blainville, 1818) based on their type specimens collected from different worldwide localities: <em>Neanthes chilkaensis</em> (Southern, 1921) from India, <em>N.&nbsp;galetae</em> (Fauchald, 1977) from Panama, <em>N.&nbsp;helenae</em> (Kinberg, 1865) from St&nbsp;Helena Island, and <em>N.&nbsp;mossambica</em> (Day, 1957) from Mozambique. The morphology of the types was re-examined for the first time after the species were originally described, and incorporated the recent improvements in the standards and terminology for describing nereidid features. The arrangement of paragnaths on area VI stood out among the diagnostic features used to distinguish these four species. <em>Neanthes chilkaensis</em> and <em>N.&nbsp;helenae</em> are the unique nereidids bearing p-bar paragnaths on the area&nbsp;VI. Both species are also distinctive as the former species only exhibited p-bar paragnaths on the area&nbsp;VII–VIII and the latter ventrolateral projections on the apodous segment. Further examination revealed that <em>N.&nbsp;nanciae</em> (Day, 1949) from St&nbsp;Helena is a junior synonym of <em>N.&nbsp;helenae</em>. Moreover, <em>N.&nbsp;galetae</em> and <em>N.&nbsp;mossambica</em> are distinguishable from other species also by the development of dorsal cirri, neuropodial postchaetal lobe and ventral ligule, the presence/absence of merged paragnaths on area IV, paired oesophageal caeca, among other features. This study has further contributed to the morphological delimitation of the species in <em>Neanthes</em> as a first step towards revising the genus.</p> Tulio F.

After a revision of 171 specimens collected from Guerrero and Oaxaca, six new species, belonging to five genera, were discovered: <em>Amakusanthura guerrerensis</em> sp.&nbsp;nov., <em>Cortezura caeca</em> sp.&nbsp;nov., <em>Mesanthura antenniformis</em> sp.&nbsp;nov., <em>M. estacahuitensis</em> sp.&nbsp;nov., <em>Skuphonura oaxaquensis</em> sp.&nbsp;nov., and <em>Tinggianthura mexicana</em> sp.&nbsp;nov. In this work, the genera <em>Amakusanthura</em> Nunomura, 1977 and <em>Tinggianthura</em> Chew, Abdul-Rahim &amp; Haji Ross, 2014, are recorded for the first time in the Tropical Eastern Pacific. Also, the distribution range of the genus <em>Skuphonura</em> Barnard, 1925 is increased from the west coast of South America to the southern Mexican Pacific, this being the first record of this genus in the Mexican Pacific. This study doubles the number of species recorded of Anthuridae from the Mexican Pacific, of six to 12 species.</p> Ubaldo Jarquín-Martínez, María del Socorro García-Madrigal Copyright (c) 2021 Ubaldo Jarquín-Martínez, María del Socorro García-Madrigal https://creativecommons.org/licenses/by/4.0 https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/1441 Wed, 21 Jul 2021 03:38:00 -0700 Proposal of two new genera of the family Zosimeidae Seifried (Copepoda: Harpacticoida): Heterozosime gen. nov. and Acritozosime gen. nov. https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/1439 <p>In the Pacific Ocean, the taxonomy of the family Zosimeidae Seifried, 2003 is poorly understood and to date only five species of the genus <em>Zosime</em> Boeck, 1873 are known. During oceanographic cruises exploring the species diversity of harpacticoids, two undescribed zosimeid copepods were sampled from shallow Korean waters and the deep northwestern Pacific. A detailed morphological examination has led us to propose two new genera, <em>Heterozosime</em> gen. nov. for the Korean zosimeid <em>H. tenuis</em> gen. et sp.&nbsp;nov. and <em>Acritozosime</em> gen. nov. for the deep-sea zosimeid <em>A. spinesco</em> gen. et sp. nov. Both new genera exhibit a distinctive feature in that the first thoracic leg has a two-segmented exopod, in contrast to the three-segmented exopod of this leg in all known zosimeid genera. Furthermore, <em>Acritozosime</em> gen. nov. can also be discriminated from other genera by the two-segmented endopod in second to fourth thoracic legs and the reduced setal armatures of the second exopodal segment of antenna, the first endopodal segment of first to third thoracic legs and the third exopodal segment in second to fourth thoracic legs. A comparison of the fundamental structures of appendages suggests that <em>A. spinesco</em> gen. et sp. nov. experienced a unique evolutionary history within the Zosimeidae.</p> Jong Guk Kim, Jimin Lee Copyright (c) 2021 Jong Guk Kim, Jimin Lee https://creativecommons.org/licenses/by/4.0 https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/1439 Mon, 19 Jul 2021 01:26:19 -0700 Two new species of cheilostomate Bryozoa from Iberian waters https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/1437 <p>Two new species of cheilostomate bryozoans are described from material preserved in museums: <em>Cradoscrupocellaria severoi</em> sp. nov., from Iberian Mediterranean waters, and <em>Setosella margaritae</em> sp. nov., from shallow waters along the Atlantic coast of Europe. Moreover, the Mediterranean species <em>Setosella cyclopensis</em> Rosso, Di Martino &amp; Gerovasileiou, 2020 is reported in Iberian waters for the first time.</p> Oscar Reverter-Gil, Javier Souto Copyright (c) 2021 Oscar Reverter-Gil, Javier Souto https://creativecommons.org/licenses/by/4.0 https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/1437 Thu, 15 Jul 2021 03:13:22 -0700 Relicthemisia, a new subgenus of the oil-collecting bee genus Centris Fabricius, 1804 with notes on distribution and host plants of C. xanthomelaena Moure & Castro, 2001 (Hymenoptera: Apidae) https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/1435 <p><em>Centris xanthomelaena</em> Moure &amp; Castro, 2001 is a relict species, endemic to northeastern Brazil and broadly recorded within the semiarid region of Caatinga xerophilous open vegetation. It was originally included in the subgenus <em>Paracentris</em> Cameron, 1903 but posteriorly interpreted as remotely related to it or to the subgenus <em>Centris</em> s. str. Fabricius, 1804. In this paper it is proposed to recognize this species as the single member of the monotypic <em>Relicthemisia</em>, a new subgenus which belongs to the ‘<em>Centris</em> group’, one of the main internal lineages of the genus. The proposition of this new subgenus is based on both, morphological and molecular data which indicate its long history as a distinct lineage. Distribution records, floral hosts as well as photographs of both sexes of <em>C. xanthomelaena</em> are also provided.</p> Felipe Vivallo, Fernando César Vieira Zanella Copyright (c) 2021 Felipe Vivallo, Fernando César Vieira Zanella https://creativecommons.org/licenses/by/4.0 https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/1435 Wed, 14 Jul 2021 01:55:45 -0700 Proposal of new genera and species of the subfamily Diosaccinae (Copepoda: Harpacticoida: Miraciidae) https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/1433 <p>Representatives of several genera of the family Miraciidae (Copepoda: Harpacticoida) were found in sediment samples taken in the year 2019 from a coastal system in north-western Mexico. The subfamily Diosaccinae (Miraciidae) was by far the most diverse taxon followed by the subfamily Stenheliinae (Miraciidae). Here we report on a new miraciid species, <em>Typhlamphiascus medici </em>sp. nov., and provide a new amended diagnosis for <em>Typhlamphiascus</em> Lang, 1944 along with a key to its species. Additionally, <em>Typhlamphiascus lamellifer lamellifer</em> (Sars, 1911) and <em>T. l. capensis</em> Kunz, 1975 are considered as distinct species and the latter is given full species rank. Upon preliminary inspection, another diosaccin species was thought to be a derived form of <em>Bulbamphiascus</em> Lang, 1944. This promoted us to perform a more in-depth phylogenetic analysis. Our results showed that the new presumed derived form of <em>Bulbamphiascus </em>represents a new genus, <em>Spinodiosaccus </em>gen. nov. and that the genus <em>Bulbamphiascus</em>, which we propose a new amended diagnosis for, could be split into different genera. Also, the possible relationships amongst the different diosaccin clades found during our analyses are commented. We give a brief ecological analysis on the distribution of <em>T. medici </em>sp. nov. and <em>S. primus </em>gen. et sp. nov. in the Urías system.</p> Samuel Gómez, Paulo Henrique Costa Corgosinho, Karen I.

The fauna of <em>Andrena</em> was largely revised in the 1970s, but since then, it has received little attention. Molecular investigation of the taxonomically challenging subgenus <em>Taeniandrena</em> has revealed that the situation is more complicated than previously thought with several cryptic and overlooked species. From the species allied to <em>Andrena</em> (<em>T. </em>) <em>gelriae</em> van der Vecht, 1927, <em>Andrena</em> (<em>T. </em>) <em>gredana</em> Warncke, 1975 stat. nov. from Spain and Portugal is raised to species status, and <em>Andrena</em> (<em>T. </em>) <em>levante</em> Wood &amp; Praz sp. nov. from southeastern Spain is newly described. Furthermore, <em>Andrena</em> (<em>T. </em>) <em>benoisti</em> Wood &amp; Praz sp. nov. is described, having previously been referred to as <em>Andrena</em> (<em>T. </em>) <em>wilkella beaumonti</em> Benoist, 1961. <em>Andrena</em> (<em>T. </em>) <em>beaumonti</em> stat. rev. is itself distinct and restricted to the High Atlas Mountains of Morocco. Outside of the subgenus <em>Taeniandrena</em>, <em>Andrena</em> (<em>Euandrena</em>) <em>fortipunctata</em> Wood sp. nov. and Andrena (<em>Charitandrena</em>) hattorfiana nigricauda Wood subsp. nov. are described from Spain, and <em>Andrena</em> (<em>Notandrena</em>) <em>juliana</em> Wood sp. nov. is described from Spain and Portugal. The male of <em>Andren</em>a (<em>Lepidandrena</em>) <em>baetica</em> Wood, 2020 is also described. <em>Andrena</em> (<em>Euandrena</em>) <em>impressa</em> Warncke, 1967 stat. nov. is raised to species status, displaying a West Mediterranean distribution. Finally, a further two species of <em>Andrena</em> are newly recorded for Spain, <em>Andrena laurivora</em> Warncke, 1974 and <em>Andrena confinis</em> Stoeckhert, 1930. Altogether, these findings reinforce the fact that our understanding of the taxonomy and distribution of <em>Andrena</em> in southern Europe remains incomplete.</p> Thomas J.
