Type material.

Holotype male: CHINA: Sichuan Province, Tibetan Autonomous Prefecture of Garzê, Luding County, Moxi Town, Hailuogou, 3600 m above sea level, 12-viii-2015, collected by Hong-Ping Zhan (GUGC).

Etymology.

The specific epithet was derived from place name, Moxi Town, where the species was collected and the type locality is located, combined with the Latin suffix -ensis, meaning from a locality.

Description.

[Holotype] Body color. Background yellow brown. Crown (Fig. 4) dark brown. Face (Fig. 6) yellow brown to dark brown, eyes brown, marked with reddish; antenna yellowish brown; frons dark to black except on ocelli and middle line; clypeus with central area dark or black on both sides of middle line, distal half chocolate. Pronotum (Fig. 4) dark brown with evenly dispersed darker spots. Scutellum and legs coloration similar to O. konkaensis sp. nov. Forewing (Figs 5, 6) with basal half dark brown and distal half yellowish brown.

Body appearance. Relatively stout. Head including eyes (Fig. 4) slightly narrower than pronotum. Face across eyes (Fig. 6) broader than long, central region with obvious punctures. Pronotum (Fig. 4) 2.5 × wider than long, with fore-margin strongly protruding forward, and hind margin slightly depressed in middle. Scutellum (Fig. 4) 1.2 × longer than pronotum. Other features as in O. konkaensis sp. nov.

Male abdominal apodemes of second tergite (Fig. 19) broad, close to each other, twisted caudally. Apodemes of second sternite (Fig. 20) relatively small, basally broad, tapered to acute or subacute apex, and pointed inwards; distance between apodemes nearly 3 × their middle length.

Male genitalia. Pygofer side (Fig. 17) basally broad, dorsal and caudal margins straight. Subgenital plate (Fig. 18) approximately 2/3 length of pygofer ventral margin. Aedeagus (Figs 21, 22) broad basally, shaft tapered to acute apex in lateral view, slightly narrowed in middle, apex rounded in ventral aspect, gonopore apical. Dorsal connective (Fig. 23) with large process bent ventrocaudally from inner ventral margin with bifurcated end and sinuated margins; with extremely slender process pointed ventrad near base. Style apex bent dorsad and irregularly tapered (Fig. 24); connective (Figs 25, 26) typical.

Measurement.

Body length (including tegmen): 5.4 mm.

Distribution.

Sichuan (Fig. 65).

Host.

Betula spp. ( Betulaceae ).

Remark.

This species is similar to Oncopsis konkaensis sp. nov. in the body coloration and external morphology, and somewhat similar in the shape of the dorsal connective, but can be distinguished from the latter by the different coloration of the face, and the shapes of the aedeagus, style and the dorsal connective.
