Composition of the genera Gnaptorina Reitter and Pseudognaptorina Kaszab of the tribe Blaptini (Coleoptera, Tenebrionidae)

摘要

Based on the structure of the segments of the male fore and middle tarsi, three subgenera are distinguished in the genus Gnaptorina Reitter: Gnaptorina s. str. (brushes or tufts of pale setae are present on the sole surface of the 1st-3rd segments of the fore tarsus and also on the 1st and 2nd segments of the middle tarsus, the type species Gnaptorina felicitana Reitter, 1887), Boreoptorina subgen. n. (a brush is present on the sole surface of the 1st segment of the fore tarsus, but is absent on the sole surface of the segments of middle tarsus, the inner margin of the male fore tibia with a hairy brush, the type species Gnaptorina cordicollis G. Medvedev, 1998), and Hesperoptorina subgen. n. (a flat hairy brush is present only on the sole surface of the 1st segment of the fore tarsus, type species Gnaptorina brucei Blair, 1923). The genus Pseudognaptorina Kaszab, 1977 is considered monotypical. Lectotypes of four species of Gnaptorina are designated.
