A new species of the genus Ectromopsis Antoine, 1949 from Turkey (Coleoptera: Tenebrionidae)

Ectromopsis merkli sp. n. (Coleoptera: Tenebrionidae: Helopini) is described from Central Anatolia (coast of Eğirdir Lake). The species is the most similar to E. tantilla Ménétriés, 1848 from the Caspian depression (European Russia, West Kazakhstan) and differs in the body shape, structure of genae, the shape of pronotum and elytral punctation. Brief information about a relic type of distribution, trophic associations and adaptations of Ectromopsis spp. are given, as well as a key to species from the eastern part of the range.

The Fossil Record of Darkling Beetles (Insecta: Coleoptera: Tenebrionidae)

The fossil record of Tenebrionidae (excluding the Quartenary) is presented. In total, 122 fossil species, clearly belonging to the family, are known; some beetles were determined only to genus; 78 genera are listed in the fossil record, including 29 extinct genera. The great diversity of tenebrionids occurs in the Lower Cretaceous Lagerstätte of China (Yixian Formation), Middle Paleocene of France (Menat), Lower Eocene deposits of Germany (Geiseltal), Upper Eocene Baltic amber (Eastern Europe), Upper Eocene deposits of Florissant Formation (USA) and Miocene (Dominican amber). Tenebrionids of the following major lineages, including seven subfamilies, are currently known in the fossil record. These include the lagrioid branch (Lagriinae, Nilioninae), pimelioid branch (Pimeliinae), and tenebrioid branch (Alleculinae, Tenebrioninae, Diaperinae, Stenochiinae). The importance of the fossil record for evolutionary reconstructions and phylogenetic patterns is discussed. The oldest Jurassic and Early Cretaceous darkling beetles of the tenebrionoid branch consist of humid-adapted groups from the extant tribes Alleculini, Ctenopodiini (Alleculinae), and Alphitobiini (Tenebrioninae). Thus, paleontological evidence suggests that differentiation of the family started at least by the Middle Jurassic but does not indicate that xerophilic darkling beetles differentiated much earlier than mesophilic groups

Taxonomic structure and relationships of the genus Cylindronotus Faldermann, 1837 (Coleoptera, Tenebrionidae)

This paper deals with the systematic position and taxonomic structure of the genus Cylindrinotus Faldermann, 1837 (tribe Helopini, subtribe Cylindrinotina). Two basic concepts about systematic position and structure of the genus Cylindrinotus are discussed : 1) Cylindrinotus sensu lato (sensu Reitter, 1922, but without Nesotes Allard, 1876, Stenomax Allard, 1876 and Xanthomus Mulsant, 1854) ; 2) Cylindrinotus sensu stricto (nominative subgenus of the genus Cylindrinotus sensu Reitter, 1922). The second concept seems to be justified since cylindrinotoid and nalassoid genera are different evolutionary lineages. Monophyly and generic status of Cylindrinotus seems plausible. Taxonomical position of the genera Odocnemis Allard, 1876 and Cylindrinotus will remain unclear until larval stages of these groups are examined.Cet article traite de la position systématique et de la structure taxinomique du genre Cylindrinotus Faldermann, 1837 (tribu Helopini, sous-tribu Cylindrinotina). Deux concepts fondamentaux de la position systématique et de la structure du genre Cylindrinotus sont discutés : 1) Cylindrinotus sensu lato (sensu Reitter, 1922, mais sans Nesotes Allard, 1876, Stenomax Allard, 1876 ni Xanthomus Mulsant, 1854) ; 2) Cylindrinotus sensu stricto (sous-genre nominatif du genre Cylindrinotus sensu Reitter, 1922). Le deuxième concept semble être justifié puisque les genres «cylindrinotoïdes » et «nalas-soïdes » appartiennent à des lignées évolutives différentes. La monophylie et le statut générique de Cylindrinotus semblent plausibles. La position taxonomique des genres Odocnemis Allard, 1876 et Cylindrinotus Faldermann, 1837 restera peu claire tant que les stades larvaires de ces groupes ne seront pas étudiés.Nabozhenko Maxim V.

Idahelops alpagutae (Coleoptera: Tenebrionidae: Helopini): a new genus and species from the Aegean region of Turkey

WOS: 000300840700005Idahelops alpagutae, a new genus and species, is described from Aegean region of Turkey (Balikesir and Izmir provinces). Idahelops belongs to the cylindrinotoid group of the subtribe Cylindrinotina. The genus is close to Armenohelops Nabozhenko, 2002, from which it differs in the presence of large granules on the elytral intervals, the epipleural carina raised and reaching the elytal apex (the apical part of the elytra of Armenohelops is sloping, without a horizontal platform), and the completely pubescent body (Armenohelops is without pubescence).TUBITAK (TBAG)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [108T467]The authors thank Nursen Alpagut Keskin (Bornova-Izmir, Turkey) for her help during the project, Svetlana Nabozhenko (Rostov-on-Don, Russia) for her help in collecting beetles during the expedition, Galina Glushchenko (Shvyrkova) (Institute of Arid zones, Rostov-on-Don, Russia) for her help with illustrations, Otto Merkl (HNHM) and Aaron Smith (International Institute for Species Exploration, Arizona State University, USA) for helpful comments.

Idahelops Keskin & Nabozhenko, 2012, gen. n.

Idahelops gen. n. Type species: Idahelops alpagutae sp. n. Description. Body slender, with light bronze shine, densely covered with recumbent light-grey setae. Temple grooves deep. Propleura with coarse short wrinkles and recumbent hairs. Intervals of elytra covered with large granules. Epipleural carina wide, completely visible dorsally, forming a horizontal platform at the elytral apex. Lateral margins of elytra not sinuated in base and near apex. Epipleura pubescent, flattened or weakly depressed, reaching apex of elytra. Interval 8 flattened apically and connected with interval 3. All tibiae straight, without teeth or granules on inner side. Tarsomeres of male not dilated. Parameres very short, weakly arcuate dorsally. Gender. Masculine. Etymology. The genus name refers to the type locality – the Ida Mountains (now Kaz Dagi). Differential diagnosis. Idahelops gen. n. is close to Armenohelops, from which it differs by the presence of large granules on the elytral intervals, the epipleural carina reaching the elytral apex and forming a horizontal platform (elytral apex sloping in Armenohelops), completely pubescent body (Armenohelops is without pubescence) and the structure of the male genitalia. The parameres are very short and dorsally slightly arcuate in both Armenohelops and the new genus. This allows the parameres to turn strongly dorso-ventrally, facilitating guidance of the aedeagus during copulation. Armenohelops has a short penis and sclerotized rods, reaching only the level of the base of the parameres at rest. Idahelops, unlike Armenohelops, has a long penis and sclerotized rods which are located in the parameres at rest. Species of the genus Armenohelops also have rudimentary photosensitive sensillae on the elytra, but these are not specialized and poorly developed. Idahelops differs from the other genera of the cylindrinotoid group by the structure of the parameres, completely densely pubescent body, and by the absence of granules or teeth on the inner side of the tibia. Idahelops alpagutae sp. n. (Fig. 1–3) Description. Male (fig. 1 b). Body slender, dark-brown, with light bronze shine, completely pubescent with dense recumbent light-grey hairs. Head widest at level of eyes. Eyes large, convex. Ratio of head width at eyes to distance between eyes: 1.4 Genae regularly strongly rounded. Temple grooves deep. Head punctation coarse and dense, punctures round, their diameter about twice as wide as distance between punctures. Antennae long (reaching 1 / 3 of elytral length), densely pubescent, with 5 apical antennomeres extending beyond base of pronotum; antennomeres 8–11 flattened. Pronotum transverse (1.25 times as wide as long), widest at middle or before middle, 1.45 times as wide as head (fig. 2 a). Lateral margins of pronotum rounded, widely sinuate at base. Anterior margin bisinuate, sinuation sometimes weak. Base of pronotum weakly trisinuate. Anterior and posterior angles straight. All margins of pronotum narrowly rimmed, except for widely rimmed basal part of lateral margins. Disc of pronotum evenly convex, with smooth longitudinal middle line. Pronotal punctation same as head, with laterally denser connected punctation. Propleura covered with coarse short longitudinal wrinkles and recumbent hairs. Elytra elongate (1.7 times as long as wide), 1.3 time as wide and 2.8 time as long as pronotum. Epipleural carina wide and clearly visible in dorsal view throughout entire length. Lateral margins of elytra straight (not sinuated) near base and apically. Humeral angles widely rounded. Intervals of elytra flattened, with coarse punctation and large granules, especially laterally and apically. Strial punctures merged in entire deep furrows (only punctures of stria 8 not merged). Epipleura not depressed or weakly depressed, pubescent, reaching apex of elytra. Abdominal ventrites finely and densely punctate. Ventrite 5 not rimmed apically. Legs slender, tibiae straight, tarsi narrow. Inner side of femora shining, rugose, but not pubescent. Spines on apical margins of tibiae long and narrow. Tarsi with hair brush on plantar surface. Body length – 9–11.5 mm, body width – 3.7–4.3 mm. Genitalia. Parameres very short, curved dorsally, without deep longitudinal depression dorsally. Sclerites of penis wide, connected by sclerotized membrane (fig. 2 c, 2 d). Inner sternite VIII see fig. 2 b. Gastral spicula with: branches widely placed, not connected, straight in lateral view, without general trunk (fig. 2 e). Female (fig. 1 c). Body larger than in male, length: 11–13 mm, width: 4.5–5.5 mm. Pronotum more transverse than in male (1.28–1.3 times as wide as long). Antennae shorter than in male, 3 last antennomeres extending beyond pronotal base, but reaching only 1 / 4 of elytral length. Genitalia. Spermatheca of nalassoid type, short, without branches. Basal duct of spermatheca between gland and vagina absent. Gland of spermatheca short (fig. 3). Material. Holotype, 3 (ZDEU): Turkey, prov. Balikesir, Kaz Dagi, 39 º 44 ' 45.6 " N, 26 º 53 ' 19.9 " E, 1266 m, 25.05. 2009 (leg. M.V. and S.V. Nabozhenko, B. Keskin).
