Four new species of Ditrigona Moore (Lepidoptera, Drepanidae) in China and an annotated catalogue

Abstract

The Chinese species of the genus Ditrigona Moore, 1888 are reviewed and an annotated catalogue is provided. Four new species are described from China: Ditrigona sinespina Jiang & Han, sp. nov., Ditrigona parva Jiang & Han, sp. nov., Ditrigona concava Guo & Han, sp. nov., and Ditrigona fusca Guo & Han, sp. nov. Deroca crystalla Chu & Wang, 1987 and Auzatella pentesticha Chu & Wang, 1987 are newly combined into, respectively, the derocina and quinaria species groups of Ditrigona. Ditrigona diana Wilkinson is newly recorded in China. This results in 43 species of Ditrigona for the fauna of China. Illustrations of habitus and genitalia of the new species and most known species are presented.
