Chun-Sheng Wu (2002) A new genus, Dixognatha gen. nov., based on Athymoris nectarus Wu, is described. The new genus Dixognatha is easily separable from the all known genera in the Lecithoceridae by the forked gnathos of the male genitalia and the unique juxta. The venation of the new genus is similar to that of Athymoris Meyrick, but differs from the latter by the forewing with M₁ and R₃₊₄₊₅ being stalked (♂) or connate (♀). In addition, the author redescribes Dixognatha nectarus (Wu) n. comb., including a description of the male genitalia which has not previously been known.

Key words: Dixognatha gen. nov., Lecithoceridae, Lepidoptera.
