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 ).

Measurements (n=4). BL 35.15±2.48, HL 2.98±0.21, HW 3.32±0.14, PL 4.32±0.69, PW 5.65±0.43, TL 27.85±1.62, TW 6.87±0.32, HFL 11.85±1.31, HTL 11.74±0.76, HML 4.62±0.5.
