Type material. Holotype: CHINA: Fujian Prov.: 3, Wuyishan Mt., Tongmu Village (27°44’47”N 119°29’01”E), elev. 800 m, Zi-Wei Yin & Nan Qi leg., 28.vii.2008. Paratypes: CHINA: Jiangxi Prov.: 13, 4ƤƤ, Wuyishan Mt., elev. 950 m, Jia-Yao Hu & Liang Tang leg., 10.v.2005 (all SHNUC).

Description. Body ( Fig. 6 View FIGURES 5 – 8 ) reddish-brown; maxillary palpi and tarsi lighter in color; body length 3.53 mm, combined width of elytra 1.65 mm.

Head longer than wide, frontal margin anterior to eyes narrowed toward apex. Antenna (Fig, 95) with scape three times as long as pedicel and about three times as long as wide, pedicel shortest, antennomere III slightly longer than pedicel, IV and V subequal in length, VI 1.4 times as long as V, VII and VIII shorter than VI, about equal in length, IX–XI forming clubb, IX long, slightly shorter than scape, X much shorter than IX, slightly broadened apically, XI nearly oval, about as long as VII and VIII combined. Maxillary palpus ( Fig. 143 View FIGURES 138 – 149 ) with palpomere I minuscule, II–IV asymmetrical and protuberant laterally. Mandibles ( Fig. 130 View FIGURES 126 – 137 ) each with two big teeth and several small teeth on mesal margin.

Pronotum weakly rounded, longer than wide, coarsely punctured and densely pubescent. Elytra ( Fig. 18 View FIGURES 13 – 24 ) at base covered with long hairs, each with longitudinal sulcus reaching three-fourths of elytral length. Legs with protrochanter (Fig. 62) and profemur each bearing a short apical spine, mesotrochanter (Fig. 63) with three short apical spines, hind legs without spines.

Abdomen (Figs. 35, 36) with tergite IV about twice as long as V, tergite VIII (Fig. 113) narrowed from middle toward apex, sternite VIII (Fig. 112) with apex asymmetrical, emarginate apically.

Aedeagus ( Figs. 160, 161 View FIGURES 150 – 161 ) similar to that of P. cornutus , but median lobe gradually narrowed from middle toward apex, apex rounded, in dorsal view curved left; endophallus ( Fig. 178 View FIGURES 174 – 186 ) with four spines, two dorsal long, curved left from middle toward apex, remaining two short and stout, acute apically; parameres paired, short and almost symmetrical, each with long setae at apex, basal plate distinctively expanded inward.

Female. Smaller than male in size; antennal club indistinct; basal metaventral processes absent.

Remarks. This species is characterized by the mesotrochanter bearing three small apical teeth, and the aedeagus with the median lobe rounded at the apex.

Distribution. China (Fujian and Jiangxi Provinces).

Etymology. The species name is an adjective and refers to the name of the type locality.
