__NOTOC__ ''Lamasina'' is a genus of gossamer-winged butterflies (family Lycaenidae); the validity of its name is subject to dispute. Among its family, these sexually dimorphic Lepidoptera belong to the tribe Eumaeini of the subfamily Theclinae. ''Lamasina'' species are found mainly in northern South America, approximately to the Guyanas. ''L. draudti'' is also found in Central America south of the Yucatán Peninsula. In the Andes, the genus extends somewhat further south; ''L. rhaptissima'' almost reaches Bolivia.〔Robbins & Lamas (2008), and see references in Savela (2011)〕 The genus name has changed two times since the year 2000 for technical reasons. The question which name is correct is not yet fully resolved, though ''Lamasina'' seems to be the preferred one.〔Robbins & Lamas (2008)〕 ==Description== :''See also Glossary of Lepidopteran terms.'' They show some similarity to ''Evenus'' (probably a close relative) and ''Paiwarria'' (probably a slightly more distinct member of the Eumaeini). But whether ''Lamasina'' is in fact a close relative of the former is not thoroughly studied. The upperwings of ''Lamasina'' males and females are bluish, with broad black margins which are broader in females. The underwings are greenish to brown, with a striped or mottled pattern that distinguishes males from females. In some, the males have blue forewing undersides also.〔 ''Lamasina'' has a fairly short forewing cell, measuring less than one-half of the costal length and in males only about one-third. In some ''Lamasina'' males, androconia ("perfume" scales) form a characteristic orange or darkened patch on the dorsal forewing. There is a lobed tail at the hindwing tomus in some species. Together with the structure of the genitalia, members of this genus can thus be unequivocally recognized by this combination of characters, though most of these features are also found in other Eumaeini.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lamasina」の詳細全文を読む スポンサード リンク
