翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Theritas ： ウィキペディア英語版 Theritas ''Theritas'' is a genus of gossamer-winged butterflies (family Lycaenidae) found in the Neotropics. Among the tribe Eumaeini of its subfamily Theclinae, it is usually placed in the group around the genus ''Atlides''. In particular, it seems most closely related to ''Arcas''.〔Bálint ''et al.'' (2007), Brower (2007)〕 == Description == ''Theritas'' species are large among the Eumaeini but altogether still smallish butterflies. They typically have a pennant-like hindwing "tail" which projects outwards at an approximate right angle from the squared-off edge of the tapered tornal area. A smaller tail is located slightly more forward on the hindwing. The upperwings of these butterflies are largely or entirely colored brilliant blue. But these traits – as opposed to the androconia pouches discussed below – are also found in several other Eumaeini, which have been included in this genus but do not really appear to belong here.〔 Like ''Arcas'', they have androconia (scent scales) on the hindwing upperside near the base of the cubital vein; these are autapomorphically tucked away in a flat deep pouch in space 1b between the wing veins. Some species also have androconia on the forewings, but it needs to be clarified whether these are indeed ''Theritas sensu stricto''. The hindwing underside is brownish in these butterflies, with a subbasal line running between the subcosta and the anal vein branch of the cubital vein. This genus has some sexual dichromatism in that the males show green iridescence of the blue upperwing color. By comparison, ''Arcas'' has golden-green hindwing undersides dusted with black, with a black band running roughly parallel to the distal wing margin, longer tails, and lacks sexual dichromatism. The female genitals have a long, straight and tubular genital duct with a plain anal end in the type species ''T. mavors'', but variation within the genus is insufficiently studied.〔Bálint ''et al.''
