The genus Nemophora Hoffmannsegg, 1798 (Lepidoptera, Adelidae) from the Ryukyus

Abstract

Seven species of the genus Nemophora Hoffmannsegg, 1798 are recorded from the Ryukyus, Japan, where only one species, N. marisella Kozlov & Hirowatari, 1997, has been known. Two new species, N. tenuifasciata sp. nov. and N. pruinosa sp. nov., are described and two species, N. polychorda (Meyrick, 1914) and N. magnifica Kozlov, 1997, are newly recorded from Japan. The male and female genitalia are illustrated except for Nemophora optima (Butler, 1881), which is represented by only one female specimen from Amami-Oshima Is.
