Etymology. This new species is dedicated to the aquatic coleopteran researcher Mr. Zuqi Mai (AEȒȍ), who became good friend of the first author during their student days sharing an interest in entomology. To this day, they still go on field trips together to collect specimens and discuss research, and he has also collected many myrmeleontid specimens for us.
Biology. The larvae of E. zuqii sp. nov. inhabit rocky platforms with shallow, wet soil, completely buried into the substrate, ambushing preys ( Fig. 16 View FIGURE 16 ). Moreover, this new species is sympatric with E. xiaohongae sp. nov.
The Epacanthaclisis tuyuezhengi group
Diagnosis. Adult: Male wings narrow, blade-like, darker than that of female. Hindwing 0.85 times as long as forewing. Hind wing mostly with only one presectoral crossvein. Male terga 4–5 without any tuft setae or bristles; tergum 5 barely swollen. Male gonocoxites 9 as a pair of strongly sclerotized plates, internally with short-tapered setae; gonocoxites 11 thick and long, longer than gonocoxites 9 in lateral view. Male ectoproct laterally expanded into a digital projection, at least twice as wide as long. Female gonocoxites 9 with short stout setae.
