mytylata species group

In Wilkinson (1968) and Li et al. (2015), 15 species in the mytylata species group were recorded in China: Ditrigona lineata (Leech), Ditrigona legnichrysa Wilkinson, Ditrigona policharia ( Oberthür), Ditrigona artema Wilkinson, Ditrigona marmorea Wilkinson, Ditrigona candida Wilkinson, Ditrigona conflexaria (Walker), Ditrigona margarita Wilkinson, Ditrigona aphya Wilkinson, Ditrigona berres Wilkinson, Ditrigona chama Wilkinson, Ditrigona chionea Wilkinson, Ditrigona platytes Wilkinson, Ditrigona cirruncata Wilkinson, and Ditrigona clavata Li & Wang. A new species D. fusca is described in this work.

This species group is characterized by usually having lamellate antennae, and the valva of the male genitalia usually possessing a long posterior extension. Other characters are summarized as follows: the forewing is sometimes weakly falcate; the streaks vary considerably, with transverse lines linear, band-like or absent; the uncus is bifurcate, and the socii are very large; the aedeagus is usually arcuate; both eighth sternite and tergite are modified, the former with short octavals, and the latter concave with small or large protrusions; in the female genitalia, the ostial pocket is characteristic, and the corpus bursae lacks an accessory sac.
