Pediopsoides (Sispocnis) triangulus Li, Li & Dai sp. nov. Figs 38-48

Type material.

HOLOTYPE: ♂, CHINA: Sichuan Province, Tibetan Autonomous Prefecture of Garzê, Luding County, Minya Konka, Yajiageng, 3800 m above sea level, 13.viii.2015, collected by Zhan Hong-Ping.

Etymology.

The new species name was derived from the Latin words " triangulus " referring to the triangular processes on the lateral margins of the aedeagal shaft.

Description.

Body color. Background color (Figs 38, 39) yellow brown, punctures on body surface dark brown. Face (Fig. 40) yellowish, eyes dark brown, occasionally with reddish tinge. Pronotum (Fig. 38) with six pale yellowish subtriangular spots on posterior margin. Scutellum (Fig. 38) orange brown, both lateral corners with black triangular spots, and with dark posterior half. Forewing (Figs 38, 39) mainly pigmented by dark brown except transparent parts.

Body appearance. Head (Fig. 38) prominent frontally, clearly shorter medially than next to eyes, head including eyes as wide as pronotum. Face (Fig. 40) inflated in lateral view; frons with intensive punctures, oblique stripes and mid-carina; central part with n-shaped smooth region; ocelli closer to eyes, distance between them nearly 5 times of that from an ocellus to adjacent eye. Pronotum (Fig. 38) oblique forward and laterally, 2.7 times broader than long, with obvious, intensive and transverse striations and punc tures, anterior area near eyes depressed, posterior margin excavated in middle. Scutellum (Fig. 38) surface granulose, and scattered with punctures, mid-length about 1.8 times that of pronotum. Forewing (Figs 38, 39) with three anteapical cells, veins prominent.

Male genitalia. Pygofer (Fig. 41) broad basally, with incised dorsal and caudal margins, distal half of each ventral margin produced into two small spine-like processes which sometimes bifid. Subgenital plate (Fig. 41) narrow and elongate, nearly as long as that of ventral margin of pygofer, and with marginal setae. Aedeagus (Figs 44, 45) basally broad, with strongly developed dorsal apodeme and preatrium, shaft short, clearly narrower than basis in lateral view, lateral margins parallel in ventral view, subapex with small triangular processes directed caudally on lateral margins, apex round; gonopore apical. Dorsal connective (Fig. 43), in lateral aspect, S-shaped, process from inner ventral margin short, and horn-like. Style (Fig. 46), stem bent dorsolaterally, apex with small expansion. Connective (Figs 47, 48) typical.

Measurement.

Body length (including tegmen): 4.8 mm.

Distribution.

China (Sichuan).

Remarks.

The new species is similar to P. (S.) aomians in the pattern of body coloration, and somewhat similar to P. (S.) dilatus in male features, but can be distinguished from both by the distal half of the pygofer ventral margin with two small spine-like processes which are sometimes bifid, different shapes of the aedeagus and the dorsal connective.
