Insect biodiversity of Socotra Archipelago III
Insect biodiversity of Socotra Archipelago III
published on: 31st December 2017
Abstract: Altogether 1,564 species taxa (identifi ed at least to the genus level) from 25 orders of Hexapoda have been recorded from the Socotra Archipelago to date. In addition, members of Diplura and Ephemeroptera are known from the archipelago as well, but they have not been identifi ed so far. The most speciose order in Socotra are beetles (Coleoptera) with 540 species. The total number of endemic taxa described from the archipelago is 662 species, which represents 42% of all known species. The vast majority of species is known from the main Socotra Island (1,520 species, 635 endemic taxa). The diversity of insects in Socotra is briefly commented on and compared with the nearest archipelago – the Seychelles.Published online: 31st December 2017
Felix Ron F. F. L.New species and new distributional data on Carabidae (Coleoptera) from the Socotra ArchipelagoActa Entomologica Musei Nationalis Pragae 57(supplementum): 41-54Abstract: Three new species of carabid beetles of the tribe Lebiini are described: Glycia socotrana sp. nov., previously mentioned as Glycia cf. spencei (Gistel, 1838), from Socotra Island and Abd al Kuri Island; Apristus dioscoridus sp. nov. and Mesolestes niger sp. nov., both from Socotra Island. Acupalpus (Stenolophidius) posticalis (Putzeys, 1880), Harpalus (Cryptophonus) tenebrosus Dejean, 1829, and Metadromius sp. are recorded from the Socotra Archipelago for the first time. In addition, new distributional data from Socotra are given for several
other carabid species.Published online: 31st December 2017
Lackner Tomáš, Vienna PierpaoloHisteridae of Socotra (Coleoptera: Histeroidea)Acta Entomologica Musei Nationalis Pragae 57(supplementum): 55-76Abstract: The histerid beetles (Coleoptera: Histeridae) of Socotra Island (Yemen) are reviewed based on the material collected during the Czech expeditions undertaken between 2000 and 2012. A total of 20 species are recorded, three of which are described herein: Pachycraerus socotrensis sp. nov., Liopygus occidentalis sp. nov., and Teretrius (Neoteretrius) dispar sp. nov. Hypocaccus virescens Thérond, 1963 is transferred from the subgenus Baeckmanniolus Reichardt, 1926 to Hypocaccus s. str. Thomson, 1867 based on external morphology. Most taxa, albeit determined only up to their (sub)generic rank, are recorded from Socotra for the fi rst time. Due to poor understanding of their taxonomy, or lack of determination keys to the following (sub)genera: Tribalus Erichson, 1834, Plegaderus (Plegaderus) Erichson, 1834, Acritus (Acritus) LeConte, 1853, and Teretrius (Teretrius) Erichson, 1834, their representatives from Socotra are left without identifi cation pending revisions. The Socotran histerid fauna has been found to consist mainly of widely distributed African, Arabian/Near Eastern taxa, as well as local endemics. The occurrence of the (predominantly Holarctic) genus Plegaderus and the exclusively southeast Asian genus Liopygus Lewis, 1891 in Socotra is highly interesting.Published online: 31st December 2017
Sehnal Richard, Král David, Bezděk AlešCanuschiza of Socotra Island (Coleoptera: Scarabaeidae: Melolonthinae) Part 2. Canuschiza minuta species groupActa Entomologica Musei Nationalis Pragae 57(supplementum): 77-86Abstract: The Canuschiza minuta Lacroix, 1999 species group of the genus Canuschiza Lacroix, 1999 is revised. Canuschiza zerig sp. nov. and previously unknown female of C. minuta are described. Variability in number of antennomeres observed in females of C. minuta is briefl y discussed.

Plonski Isidor S.Colotrema socotrana sp. nov. from Socotra Island, with new records of the genus from Yemen (Coleoptera: Malachiidae)Acta Entomologica Musei Nationalis Pragae 57(supplementum): 125-131Abstract: A new species of Colotrema W ittmer, 1979 (Malachiidae: Malachiinae: Colotini) from Socotra Island is described and illustrated: Colotrema socotrana sp. nov. It is most similar to C. barbertonica Wittmer, 1991 from South Africa, but differs from the latter in colouration of the extremities and morphology of maxillary palpi and terminalia. This species represents the fi rst record of Colotrema for Socotra. In addition, C. asirensis Wittmer, 1979 and C. testacea wajjensis Wittmer, 1980 are recorded from continental Yemen for the fi rst time. A key to the species of Colotrema occurring in the Arabian Peninsula and in the Socotran Archipelago is given.Published online: 31st December 2017

This is the first report of the family Sphindidae from the archipelago.Published online: 31st December 2017
Purchart Luboš, Kamiński Marcin JanA taxonomic review of the genus Clitobius with description of a new species from Oman (Coleoptera: Tenebrionidae)Acta Entomologica Musei Nationalis Pragae 57(supplementum): 139-163Abstract: Based on external and internal morphological characters, Apithesis obesa Waterhouse, 1881 (of the monotypical genus Apithesis Waterhouse, 1881) is redescribed and transferred from the tribe Ulomini to the tribe Opatrini where it is incorporated in Clitobius Mulsant & Rey, 1859. Preliminary review of the taxonomy and distribution of Clitobius is performed. The following names are placed in synonymy: Clitobius Mulsant & Rey, 1859 = Apithesis Waterhouse, 1881, syn. nov. = Apteroclitobius Koch, 1960, syn. nov.; Clitobius ovatus (Erichson, 1843) = Halonomus salinicola Wollaston, 1861, syn. nov.; Clitobius oblongiusculus (Fairmaire, 1875) = Clitobius ovatus borkouensis Pierre, 1961, syn. nov.; Clitobius obesus (Waterhouse, 1881), comb. nov. = Clitobius pseudalatus Koch, 1960, syn. nov. Clitobius omanicus sp. nov. is described from Oman. A key to the species of Clitobius is presented. Distributional patterns within the genus are analysed and discussed.Published online: 31st December 2017
Biondi Maurizio, D’Alessandro PaolaLongitarsus doeberli, a wingless new species from Socotra Island (Coleoptera: Chrysomelidae)Acta Entomologica Musei Nationalis Pragae 57(supplementum): 165-172Abstract: Longitarsus doeberli sp. nov. (Coleoptera: Chrysomelidae: Galerucinae: Alticini), from Socotra Island is described. The new species is apparently similar to Longitarsus lederi Weise, 1889 from Caucasus with which it shares, in addition to compact body, some adaptive convergences, such as wingless condition and trend of reduction of the metatarsomere I. Based on the structure of the median lobe of aedeagus and the peculiar shape of the spermatheca, the new species shows instead the closest relationships with the species of the L. anchusae group, especially L. anchusae (Paykull, 1799) and L. anatolicus Weise, 1900.Published online: 31st December 2017
Friedman Ariel-Leib-LeonidA new species of Brachycerus from Socotra Island (Coleoptera: Curculionoidea: Brachyceridae)Acta Entomologica Musei Nationalis Pragae 57(supplementum): 173-182Abstract: Brachycerus socotranus sp. nov., endemic to Socotra Island, is described from the three specimens collected by the Czech expeditions to Socotra in 2000–2012. The new species is characterized by prominent horn-like tubercles at the base of the rostrum, intact medial groove of pronotum with strongly prominent longitudinal carina and sexual dimorphism in the form of the apical part of the elytra.Published online: 31st December 2017
Straka Jakub, Batelka Jan, Pauly AlainBees of the Socotra Archipelago (Hymenoptera: Anthophila), their biogeography and association with parasitesActa Entomologica Musei Nationalis Pragae 57(supplementum): 183-219Abstract: Taxonomy of bees (Hymenoptera: Anthophila) of the Socotra Archipelago is evaluated based on historical and newly available specimens. Four new species of Halictidae are described from the Socotra Island: Austronomia socotrana Pauly & Straka sp. nov., Lasioglossum (Hemihalictus) boswelliae Pauly & Straka sp. nov., Lasioglossum (Sphecodogastra) dioscoridis Pauly & Straka sp. nov., and Lasioglossum (Ctenonomia) dracaenae Pauly & Straka sp. nov. The correct original spelling of Eucera wfkirbyi Kohl, 1906 is restored, Eucera kirbyi Friese, 1909 being its unjustifi ed emendation and junior objective synonym. Identity of both Socotran species of Xylocopa Latreille, 1802 is clarifi ed. Lasioglossum (Evylaeus) kowitense (Cockerell, 1937), Nomioides facilis (Smith, 1853), and Nomioides rotundiceps Handlirsch, 1888 are removed from the list of bees of Socotra. In total, 28 species in 16 genera are reported from the archipelago, of which nearly two thirds are considered endemic at the species level. Biogeographic origin of Socotran bees is analysed and proposed. Host associations with beetle parasites of the families Meloidae and Ripiphoridae (Coleoptera) and cleptoparasitic bees are evaluated for the Socotran bee fauna. Obligate bee parasitoid Ripiphorus arabiafelix arabiafelix Batelka, 2009 (Coleoptera: Ripiphoridae) is reported from the archipelago (Socotra Island) for the fi rst time.Published online: 31st December 2017
