Elytra,Tokyo,38(2):267!269,November13,2010 Hind Wing Polymorphism Confirmed in the Coloninae (Coleoptera, Leiodidae) Masaaki NISHIKAWA Kashiwagaya1112!16,Ebina,243!0402Japan [email protected] Abstract The occurrence of a hind wing polymorphism in the subfamily Coloninaeisconfirmedforthefirsttime. Nothinghaspreviouslybeenknownontheoccurrenceofhindwingatrophyinany colonine beetle species, despite the existence of apterous condition ordinarily known in awiderangeofotherleiodidsubfamilyspecies(cf.N:LIDC,2005). Recently,Ifound some specimens of a brachypterous Colon species besides a specimen of macropterous conditionfromtheKamchatkaPeninsulaandSiberiainmycollection.Thesespecimens agreed with Colon (Eurycolon) latum KG66IO. This species has a record of its trivial flight observed in Czech (FA:>H8=:G, 1903) and a widespread distributional range extending from Europe to Siberia (P:GG:6J, 2004). Very recently, the species was newly recorded from the Lazovsky Nature Reserve near Vladivostok, the Russian Far East (R˚JˇO>ˇ8@6, 2009). It is therefore likely to be considered showing as a northern Palaearctic distribution in a zoogeographical pattern, though unrecorded areas among Asian localities are spacious. As for specimens of R˚JˇO>ˇ8@6’ record, their hind wings wereconfirmedasbrachypterouscondition,whichwasalsoconfirmed in those of some localities in Central and Southeastern Europe, while specimens of macropterous condi- tion were less commonly coexisting with them only at a few localities (R˚JˇO>ˇ8@6, pers. comm.). I therefore show herein the occurrence of a hind wing polymorphism in the subfamily Coloninae for the first time. This brief paper is published to promote additional observations of the hind wing condition in colonine collections worldwide, because the condition has not been used as their diagnostic character (e.g., SONB8O6@DLH@>,1969),andconsequentlyhaspossiblybeenignoredfrommorphologi- cal observations of these specimens.
