New data on the taxonomy, biology and distribution of weevils of the subgenera Sulcorhynchus Magnano, 1998 and Zelotomelus Reitter, 1912 (Coleoptera: Curculionidae: Otiorhynchus) from the Caucasus
Abstract
New data on the morphology, biology and distribution of Otiorhynchus circassicus Reitter, 1888, O. planipennis Magnano, 1999, O. pseudocircassicus Magnano, 1999, O. teberdensis Reitter, 1909 from the subgenus Sulcorhynchus Magnano, 1998 are reported. Two new subspecies, Otiorhynchus (Sulcorhynchus) planipennis proprius subsp. n. and O. (Sulcorhynchus) circassicus ivlievi subsp. n., are described. Otiorhynchus planipennis proprius subsp. n. is known only from environs of Lazarevskoe (Bolshoy Sochi, Krasnodar Region, Russia). It differs from O. planipennis planipennis in the widened antennal funicle with 2nd segment 1.13–1.55 times as long as wide. Otiorhynchus (Sulcorhynchus) circassicus ivlievi subsp. n. was found in Abago Mt. (= Kartuz). It differs from O. circassicus circassicus in the following features: the head at the level of eyes is narrower, the tooth on the fore femur is usually with additional denticles, and the pubescence on the dorsal side of the body is denser. The majority of representatives of the subgenus Sulcorhynchus are local endemic species distributed only in the Western and Central Caucasus (Russia (Krasnodar Region, Adygea, Karachay-Cherkessia, and Kabardino-Balkaria), Abkhazia). A key to species and subspecies of the subgenus Sulcorhynchus is given. Holotypes of O. inclinataesetis and O. planipennis, and lectotypes of O. circassicus and O. teberdensis were examined. The following new synonymy is proposed: O. teberdensis Reitter, 1888 = O. inclinataesetis Magnano, 1998, syn. n. An additional justification for the transfer of Otiorhynchus carcelliformis Stierlin, 1896 in the subgenus Eprahenus Reitter, 1912 is given. Otiorhynchus emrei Avgın et Colonnelli, 2011 is transferred from the subgenus Sulcorhynchus to Choilisanus Reitter, 1912. The subgenus Zelotomelus Reitter, 1912 is considered to be closely related to Sulcorhynchus. Otiorhynchus (Zelotomelus) erinaceus Stierlin, 1876 is widely distributed parthenogenetic species in the Cis- and Transcaucasia and Rostov Region of Russia (first record). The male of this species was found for the first time in the environment of Golovinka (Bolshoy Sochi).
