New species and new records of darkling beetles of the tribe Helopini (Coleoptera: Tenebrionidae) from the Western Palaearctic

New localities and data on distribution of darkling beetles of the tribe Helopini are presented. In total, 46 species from 12 genera (Adelphinus Fairmaire et Coquerel, 1866, Catomus Allard, 1876, Euboeus Boieldieu, 1865 (Pelorinus Vauloger, 1900), Helops Fabricius, 1775, Raiboscelis Allard, 1876, Entomogonus Solier, 1848, Hedyphanes Fischer von Waldheim, 1820, Nalassus Mulsant, 1854, Eustenomacidius Nabozhenko, 2006, Zophohelops Reitter, 1902, Cylindrinotus Faldermann, 1837, Odocnemis Allard, 1876) are reviewed. A  brief review of taxonomic works for each genus is given. The following new taxa are described: Adelphinus (s.  str.) baehri sp.  n. from Morocco (differs from all congeners by the presence of erect black spine-like setae on elytra), Euboeus (Pelorinus) kopetzi sp.  n. from Western Turkey (belongs to the obesus species-group, differs from all similar species with wrinkled prohypomera by the dorsally dark-blue body, and the structure of the aedeagus), Zophohelops (s.  str.) staveni sp.  n. from Eastern Turkey (similar to Z.  montanatolicus Nabozhenko et Keskin, 2014, from which it differs by the coarsely and densely puncturated pronotum, coarsely wrinkled prohypomera with sparse punctures, absence of hair brush at middle of male abdominal ventrite  1 and not beaded abdominal ventrite  5). The following new combination is proposed: Euboeus (Pelorinus) globicollis (Seidlitz, 1896), comb.  n. (transferred from Probaticus Seidlitz, 1896). Hedyphanes koltzei Heyden, 1892 is recorded for Kazakhstan for the first time. The distribution of Entomogonus saphyrinus (Allard, 1876) and Entomogonus duchoni Reitter, 1903 is corrected, both species occur only in Turkey. The species Catomus fulvipes (Reiche et Saulcy, 1857) is distributed in Syria and Israel, but not in Turkey
