Cylindrinotus tchorokhicus sp. nov. and Probations (Pelorinus) banaszkiewiczae sp. nov. are described from northeastern Turkey (Artvin Province). The first species is similar to C. constrictus (Seidlitz, 1896), but differs from it by flattened lateral sides of pronotum, strongly thickened outer margins and base of pronotum, more shining body and structure of aedeagus. The new species of Probations Vauloger, 1900 is close to P. corrugatus (Seidlitz, 1896), but differs from it by the structure and punctation of pronotum and propleura, structure of elytra and genitalia of male, and pubescence on anal sternite.
Asida groehni sp. nov. (Coleoptera, Tenebrionidae, Asidini) is described from Eocene Baltic amber from the Kaliningrad Region (Russia). This is the first fossil species belonging to the genus Asida Latreille, 1802 and only the eighth described darkling beetle species from Eocene Baltic amber. This species helps support the hypothesis that the climate in this part of Europe was warmer during Eocene, as no Asida species are currently present in the Baltic area due to not appropriate climate. This new fossil species is similar to modern Asida species in the subgenus Planasida Escalera, 1907, which occur in the Iberian Peninsula and the Maghreb, but it differs from all known Asida in pronotal sculpturing and pilosity, and by its yellow brown shiny cuticle, well visible on the pronotal disc. Despite species-level differences, the new extinct species appears to fit easily within the extant genus Asida.
A new species Nalassus bozdagus sp. nov. is described from the Aegean Region of Turkey (Bozdag ridge). The new species differs from all known Nalassus in the following characters: the hair spot on first and second abdominal sternites of male is absent, temple grooves are absent, exosceleton very strongly sclerotized. New records of Nalassus Mulsant, 1854 from Turkey are provided. Two species new for the fauna of Turkey: Nalassus (Helopondrus) gloriosus (Faldermann, 1837) and N. (Helopocerodes) faldermanni (Faldermann, 1837).
Review of the O. korbi species-group is given. 5 species and 1 subspecies, including four new taxa are known from Southern Anatolia: O. korbi (Reitter, 1902), O. perarmatus Nabozhenko et Tichý, 2006, O. svetlanae sp. nov. svetlanae subsp. nov., O. svetlanae beydagensis subsp. nov., O. nasreddini sp. nov., O. nialgorzatae sp. nov. Morphological characters of species-group, bionomics and distribution are discussed.
A new tenebrionid genus Socotraphanesgen. nov. and two new species S. kralisp. nov. and S. dementorsp. nov. (Tenebrionidae: Helopini) are described from Socotra Island (Yemen). The genus differs from all Old World Helopini by hidden frontoclypeo-labral membrane, which originates under the inner side (not from the anterior edge) of frontoclypeus. The same character is known only within xeromorphic species of American Helops Fabricius, 1775 and NeohelopsDajoz, 2001. Socotraphanesgen. nov. belongs to the subtribe Helopina based on the structure of male genitalia and can be compared with the genus Neohelops (USA, Texas), with which it shares hidden frontoclypeo-labral membrane, not expressed vertical edge at elytral base and very short metaventrite, but it differs from Neohelops by the absence of large teeth on mesocoxae and absence of deep strial fovea. Both species of the new genus have ‘helopioid’ structure of female genital tubes with multiply branched spermatheca, weakly sclerotized apical part of vagina and unusual short accessory gland, which flows to the apical part of vagina through the short and wide one-way valve.
The nomenclatural status of three darkling beetle species previously described under the name Helops gracilis, by Fisher von Waldheim in 1823, Küster in 1850 and Bland in 1864, is clarified. The status of a fourth species, a misidentification of Helops gracilis Küster by Allard (1876,1877) and Seidlitz (1896), is also discussed. The following new nomenclatural acts are included: Helops gracilis Fisher von Waldheim, 1823 is recognized as Odocnemis (Heloponotus) gracilis (Fisher von Waldheim, 1823) comb. nov. (from Helops)', Catomus kuesteri (Weise, 1878) comb. nov. (from Helops) is the valid name for Helops gracilis Küster, 1850; Helops blandi Bousquet and Bouchard, nom. nov. is proposed for Helops gracilis Bland, 1864. Odocnemis perplexus (Ménétriés, 1848) is considered a new synonym of Odocnemis gracilis (Fisher de Waldheim, 1823) and Catomus dichrous Reitter, 1902 as a new synonym of Catomus kuesteri (Weise, 1878). Lectotypes are designated for Helops gracilis Fischer von Waldheim, 1823, H. gracilis Bland, 1864 and H. seidlitzi Gebien, 1911.
