Nemoura cucurbitata Mo, Wang, Yang & Li, 2020: 145 .

Female ( Fig. 5 ). Sternum 7 extended medially, forming a well-developed, broadly circular and swollen pregenital plate, which is strongly sclerotized, overlapping sternum 8 completely and anterior margin of sternum 9. Sternum 8 shortened medially, with a pair of bicolored, rounded triangular vaginal lobes on the posterior margin, partly hidden by posterolateral edge of pregenital plate. Sternum 9 extended anteromedially, trapezoidal; paraprocts short and rounded.

Remarks. The male of this species is characterized by the gourd-shaped epiproct and the hooked apical half of outer paraproct lobe ( Mo et al. 2020h). In the present study, the female of this species is described for the first time but it is less distinctive, and cannot be distinguished from several congeners.
