Figs 23-33

Material examined.

Holotype ♂, China: Yunnan Province, Diqing Tibetan Autonomous Prefecture , Shangri-La, 08.viii.2012, collected by Zhi-Hua Fan (GUGC).

Description.

Body color (Figs 23-25 ). Dorsum yellowish brown. Head (Fig. 23 ) yellowish with intense brown maculae; face (Fig. 23 ) yellowish, punctures on surface brown, postclypeus with pair of slight brown spots, below ocelli with paired spots also, eyes dark brown with reddish tinge. Pronotum (Fig. 23 ) yellowish brown with darker striations and punctures. Mesonotum (Fig. 23 ) yellow-brown with darker punctures. Forewing (Figs 23 , 24 ) yellowish brown, several cross veins black. Legs yellow-brown with darker markings.

Body form (Figs 23-25 ). Head including eyes (Fig. 23 ) almost as wide as pronotum, crown short and nearly parallel-sided, vertex clearly projecting forward angularly. Face (Fig. 25 ) slightly depressed in central part in lateral aspect (Fig. 24 ), face including eyes wider than long, surface with clear intense punctations and striae, postclypeus with distinct longitudinal carina, distance between ocelli nearly 4.3 × that from ocellus to adjacent eye. Pronotum (Fig. 23 ) broad, 2.3 × wider than long, with weak longitudinal carina at midlength, obliquely striated, anterior margin strongly produced forward, and posterior margin concave at midlength. Mesonotum (Fig. 23 ) nearly 1.2 × as long as pronotum. Forewing (Figs 23 , 24 ) with veins prominent.

Male genitalia (Figs 26-33 ). Pygofer side (Fig. 26 ) broad basally, lobe caudally truncate with dorsal and ventral margin nearly straight, apical half distinctly serrated. Subgenital plate (Fig. 26 ) slender, shorter than ventral margin of pygofer, surface with fine setae. Dorsal connective (Fig. 28 ) S-shaped, with medial long process from its ventral margin and directed posteriorly with irregular serrated margins, apex bifurcated. Style (Fig. 29 ) angled at basal 2/5, stem parallel-margined. Connective (Figs 30 , 31 ), anterior margin wider than posterior margin, both lateral arms prolonged, and twisted dorsally. Aedeagus (Figs 32 , 33 ) broad basally, shaft slender, with lateral margins sinuated in ventral view, apex with pair of short acute processes on each side of gonopore.

Measurement.

Body length (including tegmen): 4.4 mm.

Distribution.

China (Yunnan Province).

Etymology.

The specific epithet, Pediopsoides quadrispinosus , is derived from the Latin words quadri - and spinosus, referring to the aedeagal shaft with four apical spines.

Remarks.

The new species is similar to P. (P.) jingdongensis in having the same yellowish brown body and body form and male pygofer ventral margin with distinct serrations in apical half formed by a row of numerous short regularly spaced denticles. It differs, however, from P. (P.) jingdongensis and all other congeners by its slender aedeagal shaft in lateral view with four apical spines and also by the shape of its dorsal connective.
