東京都高尾山麓で発見されたウスベニヒゲナガ属の1新種（鱗翅目，ヒゲナガガ科）

抄録

A new species of the genus Nemophora, N. takaosana Hirowatari & Yagi sp. nov., was unexpectedly found at the foot of Mt. Takao (Takaosan), Tokyo, Japan. This species might have gone unnoticed until now due to its small size, compared to other members of the family Adelidae, and its unusual emergence from late September to early October among the Japanese Adelidae. We compared this new species with its close relatives, based on their morphological characteristics and DNA barcodes.
