Xuanwua motuoensis He

Xuanwua motuoensis He, 2015: 259, 260.

Materials examined. CHINA: 4 ♂♂, Xizang, Motuo County, 24 Jul. 2015, coll. Zhaohui Pan (SNNU).

Remarks. Characters presenting here were not mentioned in He, 2015: (1) Head rather small. Occiput strongly convex. Antennal scape large, almost two times broader than rostrum. Eyes normal for the tribe; median ocellus rather large, ovoid, located between the scapes; lateral ocelli large, in close proximity to eyes. Clypeus equipped with almost straight proximal margin and emarginated distalis margin (connecting to labrum). Labrum convex medially and oblique laterally. Maxillary palpus 5 segments and ratio (from basal to apex) about 1:2.5:4:3:4.5, apical segment strongly broadened apically; labial palpus short and ratio (from basal to apex) is about 1:2:1.5, end section fusiform. (2) Pronotum strongly narrower anteriorly in dorsal view, with anterior margin straight and posterior margin sinuate; disk shining with many irregular pits posteriorly; lateral lobes lightly smooth and shining, conspicuously concave in the middle. Metanotal gland armed with a protrude backward in the middle of posterior margin (Fig. 1B). (3) Hind femur ornamented with a white spot in the middle of external surface (Fig. 1A); hind femur almost as long as hind tibia. (4) Subgenital plate somewhat triangular-like and apically narrowed. Supra-anal plate symmetrically splitting into two lobes by middle groove (Fig. 1C). Cerci normal for the tribe, pubescent. (5) Male genitalia elongate; accessory structures armed with many small spines (Fig. 2B, C, E, F).

Specimens preserved in our laboratory are varied and mainly differ from the holotype in measurements and, especially, two details of genitalia: (1) width of accessory structure (epiphallus in He & Gorochov, 2015). (2) length of epiphallic middle lobe (a pair of massive and long anterolateral sclerites in He, 2015; Fig. 2A, C, D, F).
