Megalestes omeiensis Chao, 1965: 192 [Emeishan, Sichuan]

A large-sized species restricted to the western edge of the Sichuan Basin that has not been studied further since its original description. Chao (1965) indicated the holotype (m#, Emeishan, Sichuan, 1955-vi-20, 580– 1100 m, Yang Xingchi leg.) but did not attach a type tag to the specimen. Thus, for a long time, the holotype was unknown until the first author found it as well as two paratypes in IZAS and attached type tags. This species resembles M. heros as they are both the largest species in this genus and have a similar appearance. However, it is easy to distinguish them, in that the terminal lateral lobes of the genital ligula are small and curly in M. omeiensis but very large, like wings, in M. heros .
