Adult habitus. Three ocelli. General colour brown ( Figure 9a ). Head slightly wider than pronotum; anterior ocellus much smaller than posterior ones; ocellate area with a large dark marking extending laterally, anterior margins of the marking slightly M-shaped and posterior margin arcuate, between the posterior ocelli and the tentorial callosities with two large light spots ( Figure 9b ). Antenna missing, palpi brown ( Figure 9b ). Occiput yellow. Pronotum with distinct rugosities, anterior margin gently convex. Wing membrane subhyaline, veins brown. Leg yellow brown, femorotibial joint dark brown. Cercus uniformly brown ( Figure 9a ).

Male. ( Figure 9 ). Body length 23.4 mm; fore wing length 19.1 mm, hind wing length 17.6 mm. Tergum 9 ( Figure 9b ) with sparse sensilla basiconica posteromedially. Tergum 10 ( Figure 9b ) anteromedially narrowly interrupted, the slit separating two patches of sparse sensilla basiconica, the patch covering nearly the length of the segment and 2/3 of the segment width. Paraproct strongly recurved, forming cylindrical hooks, generally brownish but with darker apex ( Figure 9b ). Sternum 9 ( Figure 9c ) with large and elliptical hammer, the surface covered by dense, small granules.

Aedeagus seriously damaged, armatures not observed.

Remarks. Acroneuria personata Harper, 1976 was originally described from Nepal. Subsequently, Zwick (1977) reported it from Bhutan. The single male specimen agrees well with the original description and illustrations of A. personata in regards to the head pattern and the dorsal terminalia. It is the first record from China.
