Measurements (n=37): WH: 0.70–0.85; LH: 0.50–0.59; LA ( holotype ): 2.43; LE: 0.15¯0.24; LT: 0.12¯0.15; LPM/WPM ( holotype ): III: 0.23 × 0.07, IV: 0.08 × 0.03; LP: 0.61–0.80; WPMax: 0.65–0.83; WPMin: 0.50–0.69; LEl: 1.00–1.45; WE: 1.45–1.80; WA: 1.30¯1.73; LMTb: 1.10–1.15; LMTr: 0.33–0.35; LAed: 0.56– 0.65; TL: 3.58–4.60 ( holotype : 3.75). Body (mature specimens) reddish brown to brown, sometimes elytra contrastly paler, yellow brown to reddish brown; mouthparts, antennae, basal narrow margin of pronotum and legs yellowish brown to red brown; mandibular palpomeres 2, 4, ocelli, bases of antennomeres 1¯2 and tarsi yellow to yellow brown. Punctation of head small, sparsely spaced, more or less regular; punctation of pronotum larger, deeper and denser than that on head, with small elongate or oval impunctate area in medio-basal portion (some specimens with narrow impunctated longitudinal band); punctation of elytra dense, distinctly larger than that on pronotum, interspaces between punctures in median part of each elytron equal to diameter of 2–4 nearest punctures; abdomen with fine regular small punctation. Pronotum with fine microsculpture, indistinct in medio-basal and lateral portions, coarser along basal margin. Habitus as in Fig. 5 . Head 1.4 times as broad as long. Eyes 1.3–1.6 times longer than temples. Maxillary palp segment 3 slightly less than three times longer than apical (4th) segment. Antennomeres with lengths widths ( holotype ): 1: 0.30 0.10; 2: 0.17 0.05; 3: 0.26 0.05; 4–6: 0.20 0.06; 7–10: 0.20 0.07; 11: 0.30 0.07. Pronotum 1.02–1.07 times narrower than head, slightly broader than long. Elytra 1.6–1.8 times longer than pronotum, 1.2–1.4 times broader than long. Metarsomere slightly more than three times shorter than length of metatibia. Abdomen slightly narrower than width of elytra. Male. Apical margin of abdominal tergite VIII with wide emargination (Fig. 48). Apical margin of abdominal sternite VIII with moderately deep emargination (Fig. 56). Aedeagus ( Fig. 38 ) with moderately small phallobase, narrowing in median part towards apex forming two very short wide latero-apical and extended apical projections with rounded apices; parameres moderately thin, distinctly longer than apex of aedeagus, with two apical and two latero-apical short setae; aedeagus with strongly sclerotized narrow dorsal lobes with small rounded apex exceeding apex of aedeagus with very thin flagellum within it; endophallus with paired narrow fields of thorns and two apical portions with long setae (see inverted internal sac in Fig. 38 ). Aedeagus laterally as in Fig. 41 . Female. Apical margins of abdominal tergite VIII (Fig. 49) and sternite VIII (Fig. 57) widely rounded. Comparative notes. Based on the shape of apical portion of aedeagus with latero-apical and apical projections, Ph . wrasei sp.n. is similar to Ph . tridentatus sp.n. and Ph . tibetanus sp.n. From Ph . tridentatus sp.n. it differs by the longer parameres and dorsal lobes, by the slightly wider temples, by the narrower pronotum and shorter elytra. From Ph . tibetanus sp.n. it differs by the significantly narrower flagellum and by the more simple structure of the internal sac, by the more distinct punctation of head, by the smaller punctation of slightly narrower pronotum. From both species it differs by the general shape of the aedeagus, its narrower phallobase and median lobe, and by the shorter latero-apical projections of the median lobe. Etymology. The species is named after carabidologist David Wrase ( Berlin ), who collected some type specimens. Distribution. The new species is known from type localities ( Fig. 58 ) in Erlang Shan and Daxue Shan ranges in Sichuan , China . Bionomics. According to personal communication of M. Schülke, the specimens from the Eastern Erlang Shan Pass were collected (together with Ph . michaeli sp.n. ) by sifting in the mixed deciduous and coniferous forest with Salix near water and along small creeks in the forest and under stones. The specimens from the Camp 2 at the Gongga Shan trail were collected surrounded by a primary mixed forest with large amonts of dead wood near small creeks, mostly from thermal sources, one of them was directly inside the camp. The species is recorded from elevations between 2550 m a.s.l. to 4200 m a.s.l. The beetles were collected from May to June.
