Figs 44-53

Material examined.

Holotype ♂, China: Yunnan Province, Lushui City, Pianma Town , 26°0′34″N, 98°37′55″E, 1152 m above sea level, 26.v.2019, collected by Jia-Jia Wang and Chao Zhang ; Paratype: 1 ♂, same data as the holotype (GUGC) .

Description.

Body color (Figs 44-46 ). Head yellowish brown; face (Fig. 46 ) with postclypeus with large pale brown area centrally, anteclypeus with black apical half, eyes brown to black with reddish tinge. Pronotum (Fig. 44 ) yellowish brown on regions near eyes and lateral margins, other parts dark brown to black. Mesonotum (Fig. 44 ) yellowish brown, basal triangles and two small round spots between them black, median stripe dark brown. Forewing (Figs 44 , 45 ) brown, veins darker. Legs yellowish brown with black marks.

Body form (Figs 44-46 ). Head across eyes (Fig. 44 ) narrower than pronotum, crown short, parallel sided. Face across eyes (Fig. 46 ) wider than long, surface with clear punctures and striae, upper part of postclypeus with weak longitudinal carina, distance between ocelli nearly 6.2 × that from ocellus to adjacent eye. Pronotum (Fig. 44 ) with indistinct longitudinal carina medially, 2.9 × as wide as long, with weak oblique striations, anterior margin roundly produced in front of eyes and posterior margin concave at midlength. Mesonotum (Fig. 44 ) ~ 1.7 × as long as pronotum, triangular. Forewing (Figs 44 , 45 ) with venation prominent.

Male genitalia (Figs 47-53 ). Pygofer side (Fig. 47 ) broad basally, lobe stout, slightly prolonged caudally, with dorsal margin straight with rounded caudal margin, ventral margin infolded, caudal half with prominent tooth-like distal process preceded by a series of small teeth (Fig. 48 ). Subgenital plate (Fig. 47 ) shorter than ventral margin of pygofer, surface with fine setae. Dorsal connective as in Fig. 49 . Style (Fig. 50 ) angled at about basal 2/5, stem slightly broader in central part and slightly narrowed subapically. Connective (Fig. 51 ), anterior margin wider than posterior margin, both lateral arms twisted dorsally. Aedeagus (Figs 52 , 53 ) basally broad, dorsal apodeme developed; in lateral aspect, shaft gradually tapered to acute apex, bent dorsally, nearly U-shaped, in ventral view, weakly tumid at midlength, apex rounded, without process, gonopore apical.

Measurement.

Body length (including tegmen): 4.6-4.7 mm.

Distribution.

China (Yunnan Province).

Etymology.

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

Remarks.

The new species has the dorsal connective similar to that in P. (P.) ailaoshanensis , but can be distinguished from the latter by the simple aedeagal shaft without processes; it differs from other congeners by the combined features of dorsal connective, aedeagus and male pygofer processes.
