Material examined.

Holotype ♂, China: Yunnan Province, Yuxi City, Ailaoshan National Natural Reserve , 2400 m above sea level, 08.viii.2015, collected by Yun-Fei Wu and Jia-Jia Wang (SUHC).

Description.

Body color (Figs 1-3 ). Dorsum yellowish to brown. Head (Fig. 1 ) yellowish, frontal margin of central part pale brown; face (Fig. 3 ) evenly yellowish except postclypeus with large pale brown spot centrally and anteclypeus brown to black; eyes brown with reddish tinge. Pronotum (Fig. 1 ) yellowish adjacent to eyes, other parts dark brown, posterior margin nearly black. Mesonotum (Fig. 1 ) yellow-brown, basal triangles dark brown, striations, and punctures on surface darker brown. Forewings (Figs 1 , 2 ) pale brown, veins darker brown. Legs yellowish with brown markings.

Body morphology (Figs 1-3 ). Head including eyes (Fig. 1 ) narrower than pronotum, crown short, parallel sided. Face across eyes (Fig. 3 ) wider than long, surface with clear punctures and stripes, distance between ocelli nearly 8.2 × that from ocellus to adjacent eye. Pronotum (Fig. 1 ) broad, 2.5 × wider than long, with almost transverse striations, anterior margin convex and posterior margin concave at midlength. Mesonotum (Fig. 1 ) ~ 1.5 × longer than pronotum. Forewing (Fig. 1 ) with veins prominent.

Male genitalia (Figs 4-11 ). Pygofer side (Fig. 4 ) broad basally, lobe stout with truncated caudal margin, ventral margin with a few scattered setae, distal half with four or five small teeth (Fig. 5 ). Subgenital plate (Fig. 4 ) slender, shorter than ventral margin of pygofer, surface with fine setae. Dorsal connective (Fig. 6 ) strongly developed, S-shaped, with median long slender process directly mesally from ventral margin, apical half strongly curved ventrally and twisted. Style (Fig. 7 ) angled at basal 2/5. Connective (Figs 8 , 9 ) with anterior margin wider than posterior margin, and both lateral arms twisted dorsally. Aedeagus (Figs 10 , 11 ) broad basally, tapered to acute apex, shaft almost straight in lateral view, with pair of spine-like processes from lateral margins at midlength, dorsal apodeme developed but short, preatrium broad, gonopore subapical to apical on ventral surface.

Measurement.

Body length (including tegmen): 5.1 mm.

Distribution.

China (Yunnan Province).

Etymology.

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

Remarks.

The body appearance and color pattern of the new species is similar to several other congeners especially P. (P.) pianmaensis and P. (P.) flavus , but it can be distinguished by the combined features of the darker brown forewing venation, the aedeagal shaft with pair of spine-like processes, and the different shape of the dorsal connective.
