簡介
角尺蛾屬為東方區尺蛾科波尺蛾亞科的類群，過去已知六個種。本研究經重新評估屬級特徵，確認此屬之雄蟲生殖器共衍徵：下匙形突骨化、陽端基環與橫帶片呈U形連結、囊形突朝前方突出。此外，本研究重新評估屬內分類群身份，將原本視為日本、韓國產合角尺蛾 L. complicata (Butler, 1879)的台灣特有亞種 dactylotypa Prout, 1940處理為獨立種四線角尺蛾L. dactylotypa，並描述一產於台灣苗栗觀霧與南投塔塔加山區石山的新種煦岫角尺蛾 L. shiushioui，新種之近緣種為日本、韓國與俄羅斯產的 L. erectaria (Leech, 1897)。
Abstract
The present study re-assesses the characters of the Oriental genus Lobogonodes Bastelberger, 1909 based on all 8 species, including the newly described L. shiushioui sp. nov. and the distinct species L. dactylotypa Prout, 1940 stat. rev.. Three synapomorphic characters based on the male genitalia are proposed: the presence of a sclerotized subscaphium, the U-shaped connection between the juxta and anellus lobe and the saccus process pointed anteriorly. A new key to the species in this genus is provided.
