Type specimen: China, Yunnan Province, Gengma, Banmai .

Distribution: South China

Note: Lu et al. (2022) gave the comparison of this Chinese species with E. ampla and E. orlovi from Vietnam. Herein, we compare this species with E. pawangkhananti that is greatly similar to it. Nevertheless, these two species can be separated based on their abdominal structures. Male of E. curvata has the posteromedian process of the ninth abdominal tergite not separated from this tergite, the epiproct widely rounded at the apex and without apical lobes, and the posterior margin of the subgenital plate between its styles convex; whereas male of E. pawangkhananti has the posteromedian process of the ninth abdominal tergite separated from this tergite by a transverse fold ( Fig. 5G ), the posterior epiproctal margin with a narrow apical process, and the posterior margin of the subgenital plate between its styli almost straight.

Also, E. orlovi differs from very similar E. pawangkhananti and E. curvata in the lateral margins of the male ninth tergite proccess clearly arcuate (but in the first two species, these margins are more straight); E. pawangkhananti differs from E. orlovi and E. curvata also in a more angular apical part, in contrast with this part straight (truncate) or almost straight in the two latter species; E. curvata differs from E. orlovi and E. pawangkhananti in a widely rounded apical part of the male epiproct, whereas this epiproct has a specialized apical part in the both latter species (slightly bilobate apex and narrow apical process, respectively). Female of E. curvata is still undiscovered, therefore its comparison with other females of this genus cannot be provided.
