本文記述中國祝蛾亞科一新屬：叉顎祝蛾屬Dixognatha gen. nov.。叉顎祝蛾屬Dixognatha隸屬於瘤祝蛾亞科Torodorinae，模式種為Athymoris nectarus Wu，其雄性外生殖器的顎形突基部有一個分支，這在祝蛾科中是獨一無二的，其陽莖端基環（juxta）的形態也很奇特，代表了祝蛾科中一個特化的類群。

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.
