Figs 12-22

Material examined.

Holotype ♂, China: Guangxi Autonomous Region, Guilin City, Maoershan National Natural Reserve , 19.vii.2015, collected by Yun-Fei Wu ; Paratype 1 ♂, same data as the holotype (both SUHC) .

Description.

Body color (Figs 12-14 ). Ground color yellowish to dark brown with striations and punctures on surfaces of head, face, pronotum, and mesonotum pale brown. Head (Fig. 12 ) yellowish, anterior margin of central part weakly brown; face (Fig. 14 ) evenly yellowish except postclypeus with large slight brown spot centrally and anteclypeus brown to black apically; eyes brown with reddish tinge. Pronotum (Fig. 12 ) yellowish brown adjacent to eyes, other parts dark brown. Mesonotum (Fig. 12 ) yellow brown, basal triangles dark brown. Forewings (Figs 12 , 13 ) dark brown with venation concolorous. Legs yellowish grey.

Body morphology (Figs 12-14 ). Head including eyes (Fig. 12 ) narrower than pronotum, crown shorter near eyes. Face including eyes (Fig. 14 ) wider than long, with clear punctures and striations, postclypeus (Fig. 14 ) with weak longitudinal carina; distance between ocelli nearly 7.5 × that from ocellus to adjacent eye; pronotum (Fig. 12 ) 2.9 × broader than long, with weak transverse striations, mesonotum (Fig. 12 ) about 1.6 × as long as pronotum.

Male genitalia (Figs 15-22 ). Pygofer side (Fig. 15 ) broad basally, relatively narrow, and prolonged caudally, ventral margin with scattered marginal setae, caudal half produced into a prominent but short spine-like process preceded by three or four spines (Fig. 16 ). Subgenital plate (Fig. 15 ) slender, slightly shorter than ventral margin of pygofer, with fine setae. Dorsal connective (Fig. 17 ), stout, S-shaped, axe-like, apical half wide with distinct serrated margins. Style (Fig. 18 ) angled at basal 1/3, stem gradually widened to apex. Connective (Figs 19 , 20 ), anterior margin wider than posterior margin, both lateral arms twisted dorsally. Aedeagus (Figs 21 , 22 ) simple, broad basally, bent dorsally, and gradually tapered to acute apex in lateral view, shaft of uniform width, with rounded apex in ventral view, gonopore near apex on ventral surface.

Measurement.

Body length (including tegmen): 4.5-4.6 mm.

Distribution.

China (Guangxi Autonomous Region).

Etymology.

The specific epithet refers to the type locality of the new species, Maoershan National Natural Reserve, combined with the Latin adjectival suffix - ensis, meaning from a place.

Remarks.

This new species is similar to P. (P.) bispinatus in appearance and coloration, and somewhat similar to P. (P.) ailaoshanensis , but can be distinguished from all members of the subgenus by the following combination of features: aedeagus simple, bent dorsally and gradually tapered to acute apex without processes; dorsal connective strongly developed, axe-like, with apical half with serrated margins. It can also be distinguished by the shape of the pygofer and pygofer processes.
