During the present study, we report on the discovery and description of two new freshwater crab species (<em>Potamonautes baziya</em> sp. nov., and <em>P. mariepskoppie</em> sp. nov.) from Afrotemperate forested mountain regions in the Eastern Cape and Mpumalanga provinces of South Africa, respectively. Phylogenetic evidence derived from DNA sequence data of three partial mitochondrial loci (12S rRNA, 16S rRNA and cytochrome oxidase subunit one, COI) corroborates the evolutionary distinction of the two novel species. In addition, morphological and ecological data for the two new species further delineate their evolutionary distinction from congeneric sister species. A comparison of the taxonomically important gonopods 1 and 2 and carapace features among the sister species and other known freshwater crabs of South Africa was further used to provide evidence for the distinction of the two novel species. The discovery of two new species suggest that remote mountainous areas or unsampled regions in South Africa likely harbor several novel species, reiterating a call to document aquatic inland biodiversity in forested and mountainous regions of the country.</p> Savel R Daniels Aaron Barnes Hannes Marais Gavin Gouws Copyright (c) 2021 Savel R Daniels, Aaron Barnes, Hannes Marais, Gavin Gouws 2021-12-07 2021-12-07 782 82 107 10.5852/ejt.2021.782.1591 On the diversity of subterranean beetles of the Dinarides: new leiodid taxa (Coleoptera: Leiodidae) from Serbia <p>Three subterranean leptodirine leiodid taxa, viz., <em>Bozidaria </em>Ćurčić &amp; Pavićević gen. nov., <em>Bozidaria serbooccidentalis </em>Ćurčić &amp; Pavićević gen. et sp. nov. and <em>Proleonhardella </em>(<em>Proleonhardella</em>) <em>tarensis </em>Ćurčić &amp; Pavićević sp. nov., are described and diagnosed. <em>Bozidaria </em>Ćurčić &amp; Pavićević gen. nov. belongs to the phyletic series of “<em>Leonhardella</em>”. The new beetle taxa differ from their closest relatives in numerous morphological characters. They most likely belong to phyletic lineages of Pliocene age. The new leiodid taxa are endemic to the Dinaric mountain chain of western Serbia. Keys to the leptodirine leiodid genera of the phyletic series of “<em>Leonhardella</em>” and to the taxa of the genus <em>Proleonhardella </em>Jeannel, 1910 are included.</p> Srećko Ćurčić Dragan Pavićević Nikola Vesović Maja Vrbica Miloš Kuraica Đorđe Marković Matija Petković Vladimir Lazović Dejan Pantelić Fabrizio Bosco Copyright (c) 2021 Srećko Ćurčić, Dragan Pavićević, Nikola Vesović, Maja Vrbica, Miloš Kuraica, Đorđe Marković, Matija Petković, Vladimir Lazović, Dejan Pantelić, Fabrizio Bosco 2021-12-01 2021-12-01 782 55–81 55–81 10.5852/ejt.2021.782.1589 A reappraisal of the taxonomy of Neotropical Sialidae (Insecta: Megaloptera): with the description of a new genus from Cuba <p>The unique Neotropical species of the alderfly genus <em>Protosialis</em> van der Weele, 1909, <em>P.&nbsp;bifasciata</em> (Hagen, 1861), is herein transferred to the newly described genus Caribesialis gen.&nbsp;nov. This new taxon is proposed to be sister to the clade <em>Protosialis + Sialis</em> Latreille, 1802, after a phylogenetic analysis that included male genital characters scored on a previous morphological matrix of the family. Also, <em>Ilyobius nigrocephalus</em> sp.&nbsp;nov., a remarkable new species from Ecuador, is described and its phylogenetic position is discussed. Furthermore, <em>Ilyobius bimaculatus</em> (Banks, 1920) from Bolivia, known solely from the female holotype, is redescribed. Based on the present study, the Neotropical fauna of Sialidae is proposed to be constituted by two genera, one insular (Cuba) and one continental (Mexico to Chile and Argentina).</p> Adrian Ardila-Camacho Sara Lariza Rivera-Gasperín Caleb Califre Martins Atilano Contreras-Ramos Copyright (c) 2021 Adrian Ardila-Camacho, Sara Lariza Rivera-Gasperín, Caleb Califre Martins, Atilano Contreras-Ramos 2021-11-30 2021-11-30 782 21 54 10.5852/ejt.2021.782.1587 Campodeidae (Hexapoda: Diplura) from Kyrgyzstan, Central Asia, with the description of a remarkable new genus and species <p>Samples collected in Central Asia, Kyrgyzstan, have revealed a hitherto unknown diversity of Campodeidae (Diplura) in soil and cave habitats, including a new genus and species, <em>Kyrgyzstancampa</em> <em>sanare</em> Sendra &amp; Ferreira gen. et sp.&nbsp;nov., <em>Turkmenocampa edaphica</em> Sendra &amp; Sánchez-García&nbsp;sp.&nbsp;nov. and a previously recognized soil-dwelling species, <em>Campodea</em> (<em>Dicampa</em>) <em>catalana</em> Denis, 1930. <em>K</em><em>yrgyzstancampa</em><em> sanare</em> Sendra &amp; Ferreira gen. et sp.&nbsp;nov. was collected in the deep zone of an interesting geological and cultural cave, Ak-Turpak Cave, located near the western margin of Kadamjay District, Batken Province. This genus belongs to the subfamily Campodeinae, sharing the morphology of the pretarsus with <em>Eutrichocampa</em> and other related genera, but differing from them in the shape of the claws and the laminar lateral processes, in addition to its unique cupuliform organ and the macrosetal pattern on the thorax and abdomen. <em>Turkmenocampa edaphica</em> Sendra &amp; Sánchez-García&nbsp;sp.&nbsp;nov. was found in humid edaphic habitats, under stones or near roots, and is morphologically and geographically very similar to the cave-dwelling species <em>Turkmenicampa mirabilis</em> Sendra #38; Stoev, 2017, which occurs in an isolated cave in the nearby country of Turkmenistan.<span class="Apple-converted-space">&nbsp;</span></p> Alberto Sendra Alba Sánchez-García Jesús Selfa Dmitry A.

Sixteen species and one genus are newly described based on morphology and ecology (host association). The new genus is named <em>Tanmaurkiella</em> Santam. gen.&nbsp;nov. and includes two species: <em>T.&nbsp;pselaphi</em> Santam. gen. et sp.&nbsp;nov. (type species) and <em>T.&nbsp;huggertii</em> Santam. gen. et sp.&nbsp;nov., both on <em>Pselaphus heisei</em> Herbst, 1792 (Col. Staphylinidae Pselaphinae).

The total number of laboulbeniaceous species from Denmark rises from 29 to 195, which means that 166 are here reported as new country records. Among these, <em>Kainomyces isomali</em> Thaxt. deserves special mention as it is a new European record. The same applies to nine species which are reported here for the first time after their original description. For this study, an intensive sampling programme has been realized, with 429 Danish localities screened including around 1900 collections with fungi. Two new synonymies are established: <em>Laboulbenia acupalpi</em> Speg. (Spegazzini 1915a) syn.&nbsp;nov. for <em>Laboulbenia stenolophi</em> Speg. (Spegazzini 1914), and <em>Monoicomyces oxytelis</em> Huldén (Huldén 1983) syn.&nbsp;nov. for <em>Monoicomyces invisibilis</em> Thaxt. (Thaxter 1900). The new combination <em>Peyritschiella oxyteli</em> (Cépède &amp; F.Picard) Santam. comb. nov. is proposed for <em>Rheophila oxyteli</em> Cépède &amp; F.Picard including neotypification, and delimitation of <em>Peyritschiella protea</em> Thaxt. is incorporated. Lectotypes for <em>Laboulbenia polyphaga</em> Thaxt. and <em>Symplectromyces vulgaris</em> (Thaxt.) Thaxt. are designated. Nineteen species are illustrated here with photographs for the first time. Three species: <em>Eumonoicomyces papuanus</em> Thaxt., <em>Peyritschiella protea</em>, and <em>Stigmatomyces euconni</em> F.Picard, which were reported from Denmark in the literature should be removed from the Danish Funga. We have examined the following types of Thaxter from FH (Farlow Herbarium, Harvard University Herbaria): <em>Asaphomyces cholevae</em> Thaxt., <em>Dimorphomyces myrmedoniae</em> Thaxt., <em>Eumonoicomyces papuanus</em>, <em>Laboulbenia polyphaga</em>, <em>Peyritschiella protea</em>, <em>Rhadinomyces pallidus</em> Thaxt., and <em>Symplectromyces vulgaris</em>.<em> Ceratomyces pyrenaeus</em> Santam. is newly recorded from USA, and this is also a new record from the American continent. Description of the genus <em>Cryptandromyces</em> Thaxt. has been emended to incorporate the new species here described. Morphology of the antheridium in <em>Eumonoicomyces papuanus</em> is studied, and the status of the genus <em>Eumonoicomyces</em> Thaxt. vis-à-vis <em>Monoicomyces</em> Thaxt. is discussed. Identification keys are provided for genera and species. In support of the additional aim of this work to serve as a reference for the study of Laboulbeniomycetes fungi in Europe, we include maps and the Appendix 1 for comparison of the known species in the ten most diverse, better studied, European countries.</p> Sergi Santamaria Jan Pedersen Copyright (c) 2021 Sergi Santamaria, Jan Pedersen 2021-11-26 2021-11-26 782 1 425 10.5852/ejt.2021.781.1583 Taxonomic revision of the Neotropical spiders of the genus Idiops Perty, 1833 (Araneae, Idiopidae), with description of four new species <p>Neotropical species of the genus <em>Idiops</em> Perty, 1833 are reviewed, and four new species are described from Brazil: <em>I.&nbsp;duocordibus</em> Fonseca-Ferreira, Guadanucci &amp; Brescovit sp. nov., <em>I.&nbsp;guri</em> Fonseca-Ferreira, Guadanucci &amp; Brescovit sp. nov., <em>I.&nbsp;mocambo</em> Fonseca-Ferreira, Guadanucci &amp; Brescovit sp. nov. and <em>I.&nbsp;sertania</em> Fonseca-Ferreira, Guadanucci &amp; Brescovit sp. nov. The majority of species are redescribed based on the examination of the types and extensive material. Males of <em>I.&nbsp;petiti</em> (Guérin, 1838), <em>I.&nbsp;rastratus</em> (Pickard-Cambrige, 1889), <em>I.&nbsp;rohdei</em> Karsch, 1886 and <em>I.&nbsp;nilopolensis</em> Mello-Leitão, 1923, and females of <em>I.&nbsp;fuscus</em> Perty, 1833 and <em>I.&nbsp;pirassununguensis</em> Fukami &amp; Lucas, 2005, hitherto unknown, are described for the first time. <em>Idiops nilopolensis</em>, considered a nomen dubium, is revalidated. <em>Idiops fulvipes</em> Simon, 1889 is synonymized with <em>I.&nbsp;argus</em> Simon, 1889, and <em>I.&nbsp;santaremius</em> (Pickard-Cambrige, 1896) is synonymized with <em>I.&nbsp;petiti</em>. Neotypes are designated for <em>Idiops fuscus</em>, <em>I.&nbsp;nilopolensis</em> and <em>I.&nbsp;siolii</em> (Bücherl, 1953). <em>Idiops bonapartei</em> Hasselt, 1888 is considered species inquirendae, since the type is an immature female. Finally, an updated distribution map of Neotropical species is included. The genus now has 24&nbsp;species in the Neotropical region.</p> Rafael Fonseca-Ferreira José Paulo Leite Guadanucci Flávio Uemori Yamamoto Antonio Domingos Brescovit Copyright (c) 2021 Rafael Fonseca-Ferreira, José Paulo Leite Guadanucci, Flávio Uemori Yamamoto, Antonio Domingos Brescovit 2021-11-25 2021-11-25 782 1 71 10.5852/ejt.2021.780.1581 Revision of the species confused with “Nereis falsa” de Quatrefages, 1866 (Annelida, Nereididae) <p><em>Nereis falsa </em>de Quatrefages, 1866 has been regarded as a cosmopolitan species, and several species described from different localities have been regarded as junior synonyms of <em>N. falsa</em>. The present study is an attempt to resolve the taxonomic confusion in <em>N. falsa</em>, which seems to contain several distinct species due to previous inappropriate synonymy, widely distributed in the Atlantic and eastern Pacific Oceans. For this purpose, the authors first propose the resurrection of the synonymy of <em>N. falsa</em> with <em>Hediste</em> <em>diversicolor</em> that was concluded during the 19<sup>th</sup> century but disregarded later. After the fixation of the identity of <em>N. falsa</em> sensu stricto, the authors re-evaluate the proper taxonomic status of species which have previously been confused with <em>N. falsa</em>. Type, topotype and non-type specimens were examined; most species are redescribed, and others are reinstated. <em>Nereis splendida </em>Grube, 1840 is a valid Mediterranean species, and a neotype is proposed; it includes the Mediterranean populations of what is currently regarded as <em>N. falsa. </em>Consequently, <em>N. falsa</em> is transferred to <em>Hediste</em> Malmgren, 1867, and some taxonomic comments are added for the latter genus and a key to species is also included. <em>Nereis callaona </em>Grube &amp; Kröyer in Grube, 1857, <em>N. marginata </em>Grube &amp; Örsted in Grube, 1857 and <em>N. riisei </em>Grube &amp; Örsted in Grube, 1857 are restricted to tropical American shores and are all redescribed. <em>Nereis pelagica lunulata </em>Ehlers, 1901, formerly regarded as a junior synonym of <em>N. falsa</em> by Fauvel (1941), is redescribed and elevated in rank to species level. <em>Nereis lucipeta </em>Ehlers, 1908, formerly regarded as a junior synonym of <em>N. splendida</em> by Ehlers (1913) and of <em>N. falsa</em> by Fauvel (1919), is reinstated. <em>Nereis occidentalis </em>Hartman, 1945 is also redescribed. Furthermore, <em>N. ambigua </em>Treadwell, 1937, formerly regarded as a junior synonym of <em>N. riisei</em> by Monro (1933), deserves to be reinstated. Western Africa specimens recorded as <em>N. falsa</em> are newly described as <em>N. mezianei </em>sp. nov.</p> Sergio I. Salazar-Vallejo Jesús Angel De León-González Victor M.
