Batelka JanSocotra Archipelago – a lifeboat in the sea of changes: advancement in Socotran insect biodiversity surveyActa Entomologica Musei Nationalis Pragae 52(supplementum 2): 1-26Abstract: Nature conditions in the Socotra Archipelago are briefly summarised, main factors contributing to the composition and diversity of the insect fauna, i.e. geological history, geographic position, geomorphology, climatic conditions and plant diversity, are circumscribed. Results of the Socotran invertebrate biodiversity research are reviewed, the first annotated list of 40 insect genera and subgenera endemic to the Socotra Archipelago is provided. Recorded high level of endemism in the Socotra Island is in accordance with the estimated geological age and continuous stability of its ecosystem. Brief comparison of biodiversity in Socotra and Seychelles Islands – both granitic archipelagos of Gondwanan origin in the West Indian Ocean – is performed. Difference in composition of insect fauna in Socotra and allied Abd el Kuri Island is commented. Main threats and conservation issues concerning the fragile Socotran ecosystem are summarised, and examples of possible consequences for insect fauna are given. Based on comparison of scarce outputs and research activities concerning the Socotran insect fauna so far with the number of those elaborated for other countries/islands, establishing of a long-term insect survey is recommended.

Felix Ron F. F. L., Farkač Jan, Suleiman Ahmed SaeedAnnotated checklist of the Carabidae (Coleoptera) of the Socotra ArchipelagoActa Entomologica Musei Nationalis Pragae 52(supplementum 2): 75-106Abstract: The extensive material of Carabidae collected during expeditions to the Socotra Archipelago between 1999 and 2010 was studied. A total of 50 carabid species-group taxa were recognised, of which 42 were identified at species level, while eight morpho-species remain unnamed. Four species appear to be endemic to the island; 30 species are recorded here for Socotra for the first time. The majority of the Carabidae fauna of Socotra consists of species occurring in Africa and on the Arabian Peninsula. One species is cosmopolitan.
Fikáček Martin, Delgado Juan A. , Gentili ElioThe Hydrophiloid beetles of Socotra Island (Coleoptera: Georissidae, Hydrophilidae)Acta Entomologica Musei Nationalis Pragae 52(supplementum 2): 107-130Abstract: The hydrophiloid beetles (Georissidae, Hydrophilidae) of Socotra Island (Yemen) are reviewed based mainly on the material collected during the Czech expeditions undertaken between 2000 and 2012. A total of 16 species are recorded, three of which are newly described herein: Georissus (Neogeorissus) maritimus sp. nov., G. (N.) nemo sp. nov. (Georissidae) and Hemisphaera socotrana sp. nov. (Hydrophilidae). Seven species are recorded from Socotra Island for the first time: Georissus (Neogeorissus) sp., Berosus corrugatus Régimbart, 1906, Laccobius eximius Kuwert, 1890, L. minor (Wollaston, 1867), L. praecipuus Kuwert, 1890, Enochrus nitidulus (Kuwert, 1888), and Sternolophus unicolor Laporte de Castelnau, 1840. The previously published Socotran record of Sternolophus decens Zaitzev, 1909 is considered as misidentification. The Socotran hydrophiloid fauna is found to consist mostly of widely distributed African, Arabian/Near Eastern, Oriental and cosmopolitan species. The three newly described species may be considered as endemic to Socotra, but two of them seem to have close relatives in Africa and southern India. Notes on the remaining described species of the genus Hemisphaera Pandellé, 1876 are also included.

Král David, Sehnal Richard, Bezděk AlešTanyproctini (Coleoptera: Scarabaeidae: Melolonthinae) of Socotra IslandActa Entomologica Musei Nationalis Pragae 52(supplementum 2): 153-182Abstract: A review of the Socotran species of the melolonthine tribe Tanyproctini is provided. In addition to three species previously known from this island, five more including one new genus are described: Canudema homhil sp. nov. is closely related to C. socotrae Lacroix, 1994; both species differ mainly in the shape of antennomeres and external male genitalia. Tanyproctus (Tanyproctus) keithi sp. nov., T. (T.) lacroixi sp. nov. and T. (T.) wraniki sp. nov. are considered morphologically similar to T. (T.) canui Lacroix, 1999 and T. (T.) puncticeps (Waterhouse, 1881). Socotraproctus haghier gen. et sp. nov. can be characterized mainly by having considerably small eyes and elytra with longitudinal strips of scale-like shaped, whitish macrosetae. A key to Socotran Tanyproctini species is given along with their diagnostic characters including illustrations of copulatory organs and external morphology. The daily activity pattern of the taxa is discussed.

Bellés XavierPtinus bertranpetiti, a new species of spider beetle from Socotra Island (Coleoptera: Ptinidae)Acta Entomologica Musei Nationalis Pragae 52(supplementum 2): 219-222Abstract: Ptinus bertranpetiti sp. nov. (Coleoptera: Ptinidae) is described from Socotra Island. The practical absence of secondary sexual dimorphism and the structure of the aedeagus, slender and subsymmetrical, suggest that the new species must be placed in the subgenus Gynopterus Mulsant & Rey, 1868. The most peculiar characteristics of P. bertranpetiti sp. nov. refer to the aedeagus and the elytral pubescence, both with features that are unparalleled in other species of the subgenus Gynopterus.
Halstead David G. H.New species of Oryzaephilus and Silvanolomus from Socotra Island (Coleoptera: Silvanidae: Silvaninae)Acta Entomologica Musei Nationalis Pragae 52(supplementum 2): 223-231Abstract: Oryzaephilus socotraensis sp. nov. and Silvanolomus depressus sp. nov. from Socotra Island, Yemen are described, illustrated (habitus and male genitalia), and compared with similar known species.

Audisio PaoloA new species of Lamiogethes from Socotra Island (Coleoptera: Nitidulidae: Meligethinae)Acta Entomologica Musei Nationalis Pragae 52(supplementum 2): 241-248Abstract: A new species of pollen beetle of the genus Lamiogethes Audisio & Cline, 2009, L. socotranus sp. nov., is described from Socotra Island (Yemen). The new species is isolated from other East African representatives of this genus, exhibiting a general shape of male genitalia partially resembling certain Lamiogethes species known from southern Indian Peninsula. The new species is the first described Meligethinae recorded from Socotra Island, where further specialized research could enable discovery of other endemic or new species, chiefly in the genera Lamiogethes, Afrogethes Audisio & Cline, 2009, and Pria Stephens, 1830. Lamiogethes socotranus sp. nov. was regularly collected on Cephalocroton socotranus Balf.f. (Euphorbiaceae), but it could be more likely associated as larvae with an unidentified species of Leucas L. (Lamiaceae), which includes seven species endemic to Socotra Island.

Batelka JanPtilophorus purcharti sp. nov., the first ripiphorid from Socotra Island, with an account of the biogeography of the Ptilophorini (Coleoptera: Ripiphoridae)Acta Entomologica Musei Nationalis Pragae 52(supplementum 2): 269-285Abstract: Ptilophorus purcharti sp. nov. (Coleoptera: Ripiphoridae) from Socotra Island, Yemen, is described and figured. It is compared with all known Afrotropical and Palaearctic species of the genus and is considered to be a relictual species with Asian relatives. The distribution of the species seems to be restricted to the Afromontane forest habitats in Al Hagher mountain range. A preliminary phylogenetic analysis of Ptilophorini is performed and discussed. The density and length of setation on the antennal rami of Ptilophorini males are shown to be characters of potential phylogenetic importance which may help to understand the biogeography of the tribe. A preliminary hypothesis of Ptilophorini biogeography is proposed.

In addition, two common species of moth flies are newly recorded for Socotra Island: Tinearia acanthostyla (Tokunaga, 1957) and T. alternata (Say, 1824).
