Description

Adult habitus: General body colour brown. Head mostly yellowish-brown, with a black marking covering an ocellar triangle; Compound eyes black; Pronotum disc brown, mid-line darker, margins pale (Fig. 4 View Figure 4 A).

Male: The anterior edge of tergite 7 is concave in the middle and forms a " Y " - shape with one projecting sclerite. In the posterior part of the tergite, there is a raised process that slightly bifurcates to form a median ridge covered by many small sensilla basiconica. Tergite 8 has a tongue-shaped upcurved process, with many sensilla basiconica at the distal margin. Hemitergal processes of tergite 10 sclerotis z ed and finger-like, a subapical protrusion is present (Fig. 4 View Figure 4 B – C).

Penis base well sclerotised and its dorsal surface near the tip has small spines (Fig. 5 View Figure 5 ). The everted endophallus curves ventrally, with a tube-like inner sclerite apically. The entire endophallus is densely covered with slender golden-brown spines.

Distribution

China (Guizhou).

Taxon discussion

This species is similar to Neoperla infuscata Wu, 1935 , but their everted endophallus are quite different. In N. bituberculata , there are many golden-brown spines on the endophallus, while in N. infuscata , the endophallus bears only a few small spines. In addition, the tergite 7 of the N. bituberculata has two small lobes, which is also used for the etymology for this species.
