Description.

Body color (Figs 1-6). Yellow brown to dark brown or black, usually densely marked with darker maculae. Pronotum (Figs 1, 2) generally with 4-6 shallow yellowish or brown spots on posterior margin. Scutellum (Figs 1, 2) with black triangular spots on lateral corners, or evenly black.

Body appearance (Figs 1-6). Stout and wedge-shaped. Head (Figs 1, 2) with frontal margin sinuated slightly. Face (Figs 5, 6) with stripes and punctures; frons clearly with longitudinal carina in middle, and oblique striations from carina to lateral margins; lower parts of postclypeus tumid. Pronotum (Figs 1, 2) 2.5 times wider than long, scutellum 1.2 times longer than that of pronotum. Forewing (Figs 3, 4) with three anteapical and four apical cells, and occasionally with additional cross-vien(s).

Male genitalia. Pygofer (Figs 7-13) basally broad, ventrocaudal margin with multifid and inturned process usually with 2-4 figure-like or spine-like branches of different size. Dorsal connective (Figs 14-20) strongly developed, S-shaped, with bifurcate various process from inner ventral margin with dorsal branch usually larger, longer and twisted ventrad and ventral branch small, short and dorsally bent. Aedeagus (Figs 21-26) broad basally, shaft margins parallel or slightly sinuate at ventral aspect, apical dorsal margin of shaft elongate to two lobes (Fig. 22) and usually bifid at varying levels (Figs 23-26) with each lobe.

Distribution.

China (Shaanxi, Sichuan, Qinghai, Shanxi, Gansu and Yunnan).

Remarks.

After examination of many specimens, the morphological diversity of P. (S.) aomians in body color and male genital structures is now better understood. Pediopsoides (S.) aomians can be distinguished from other members of Pediopsoides (Sispocnis) largely by the multifid (2-4) figure-like or spine-like process on distal caudoventral margin of male pygofer, the bifurcate process from inner ventral margin of the dorsal connective, and the unique structure of the aedeagus. The original description of P. (S.) heterodigitatus was based on only one male from Yunnan Province of China and the shape of male genitalia according to the description of that species falls well within the variation of P. (S.) aomians as interpreted here. It is proposed herein as a junior synonym of P. (S.) aomians .
