( Figs. 8 View FIGURES 5 – 8 , 20 View FIGURES 13 – 24 , 47, 48, 66, 67, 97, 116, 117, 131, 145, 168, 169, 176)

Type material. Holotype: CHINA: Sichuan Prov.: 3, Erlangshan Mt. (30°02’38”N 102°44’12”E), elev. 1,600 m, Jia-Yao Hu & Liang Tang leg., 29.vi.2006. Paratypes: CHINA: Sichuan Prov.: 2ƤƤ, same data as holotype (all SHNUC).

Description. Male. Body ( Fig. 8 View FIGURES 5 – 8 ) with head, pronotum and legs dark brown, elytra reddish-brown, maxillary palpi and tarsi lighter in color; body length 3.04–3.07 mm, combined width of elytra 1.21–1.22 mm.

Head as long as wide, frontal margin anterior to eyes gradually narrowed toward apex. Maxillary palpus ( Fig. 145 View FIGURES 138 – 149 ) with palpomere I minuscule, II short and pedunculate, II–IV each protuberant on lateral margin.

Antenna ( Fig. 97 View FIGURES 90 – 101 ) with scape as long as next three segments combined, pedicel shortest. Antennomeres III–IV subequal in length, V 1.5 times as long as IV, VI twice as long as IV, antennomere VII with prominent angle on inner side, VIII as long as III but narrower, IX modified, basolateral part expanded, X about as long as V but wider, XI oval, as long as IX, narrowed from middle toward apex. Mandibles ( Fig. 131 View FIGURES 126 – 137 ) each with one big tooth and two to three small teeth on mesal margin.

Pronotum slightly longer than wide, coarsely punctured and densely pubescent. Elytra ( Fig. 20 View FIGURES 13 – 24 ) closest to those of P. wuyinus . Legs long and slender, protrochanter (Fig. 66) and profemur (Fig. 67) each with a long, acute apical spine, mesotrochanter with two small apical spines, hind legs not armed.

Abdomen (Figs. 47, 48) with tergite IV about four times as long as next, tergite VIII (Fig. 117) closest to that of P. miraculum , sternite VIII (Fig. 116) similar to that of P. walkeri and slightly more transverse.

Aedeagus ( Figs. 168, 169 View FIGURES 162 – 173 ) with median lobe zigzag-shaped and elongate, expanded through length, rounded at apex; endophallus ( Fig. 176 View FIGURES 174 – 186 ) asymmetrically modified, with apical part lobed, forming large spine in right half and short one in left half, basal part of endophallus in part heavily sclerotized.

Female. Antenna normal, basal metaventral process absent.

Remarks. This species is unique in the distinct shape of the antennae, and can be readily distinguished from its allies by the extremely elongate median lobe of the aedeagus.

Distribution. China (Sichuan Province).

Etymology. The specific name is in honor of Mr. Peter Hlaváč, who gives us continuous help and guidance during our work on Chinese pselaphines. The species name is a noun in the genitive case.
