PARATYPES: CHINA: 2 ♁♁ 1 ♀, same label data as the holotype (SNUC); 1 ♁, also from Fengtongzhai N. R., except ‘Dashuigou (†ķNj), 30°34′21.95″N, 102°52′54.92″E, 1594 m, 31.vii.2016.’ (SNUC).

Diagnosis of male. Length 2.79–2.82 mm; antennomere VII slightly broadened mesally, antennomere IX broadened from base to apex, antennomere X wider than long; broad metaventral processes emarginate at apex; protrochanter with thick ventral spine, profemur strongly broadened, with slender ventral spine; protibia with triangular projection near apex.

Description. Male (Fig. 4B). Body reddish brown, BL 2.79–2.82 mm. Head longer than wide, HL 0.60–0.61 mm, HW 0.52–0.53 mm; each eye composed of about 25 facets. Antennomeres IX–XI (Fig. 6A) forming distinct club, antennomere VII slightly broadened mesally, antennomere IX broadened from base to apex, antennomere X transverse. Pronotum (Fig. 6B) as long as wide, PL 0.60–0.63 mm, PW 0.61–0.62 mm, roundly narrowed from middle to apex. Elytra wider than long, EL 0.73–0.75 mm, EW 1.04–1.05 mm. Metaventral processes (Fig. 6C) broad, apically emarginate. Protrochanter (Fig. 6D) with thick ventral spine, profemur strongly broadened, with slender ventral spine; protibia (Fig. 6E) with small triangular preapical projection; middle and hind legs (Figs 6 F–G) simple. Abdomen broad at base and narrowed apically, AL 0.83–0.86 mm, AW 1.12–1.13 mm. Sternite IX (Fig. 6H) semi-membranous. Length of aedeagus (Figs 6 I–K) 0.61 mm; median lobe asymmetric, endophallus composed of three sclerites.

Female. Each eye composed of about 20 facets; antennae and legs simple. Measurements: BL 2.85 mm, HL 0.61 mm, HW 0.52 mm, PL 0.62 mm, PW 0.61 mm, EL 0.72 mm, EW 1.08 mm, AL 0.90 mm, AW 1.18 mm.

Comparative notes. The new species is placed as a member of the P. walkeri species group based on the asymmetrical male antennomere VII. Males of the new species can be readily separated from all similar congeners by the unique form of antennomeres IX–X, the broad metaventral processes with an emarginate apex, presence of a thick ventral spine of the protrochanter, a triangular preapical projection of the protibia, as well as the structure of the aedeagus.

Etymology. The specific epithet refers to the type locality of the new species, i.e., Baoxing County; adjective.

Distribution. China: Sichuan.
