The false stag beetles (''Diphyllostoma'') are a group of three species of rare beetles known only from California. Almost nothing is known of their life history beyond that the adults are diurnal and females are flightless; larvae have not been observed. Their length ranges from 5 to 9 mm; bodies are elongate, with a generally dull brown to reddish-brown color. Both body and legs are covered with longish hairs. Originally classed with the Lucanidae, ''Diphyllostoma'' have a number of characteristics not shared with any other type of stag beetle, and so in 1972 Holloway proposed a separate family Diphyllostomatidae, which has since been accepted. == Species == * ''Diphyllostoma fimbriatum'' (Fall), 1901 * ''Diphyllostoma linsleyi'' Fall, 1932 * ''Diphyllostoma nigricollis'' (Fall), 1901 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「False stag beetle」の詳細全文を読む スポンサード リンク
