Type material (3 exs). HOLOTYPE: ♁, CHINA: ‘ China: Zhejiang, An’ji County (ÊẘR), Longwang Shan Mt. (AEAEƜŊ ḨOiṖữ), Donggu-an–Qianmutian (ṪẊ –Tffim), 30°24′15″N, 119°26′36″E, ca., 1350 m, leaf litter,sifted, 08.vi.2012, Hu &Yin leg.’ (SNUC). PARATYPES: CHINA: 2 ♁♁, same label data as the holotype (SNUC).
Diagnosis of male. Length 3.19–3.27 mm; antennomere VII slightly broadened mesally, antennomere IX roundly triangular, with small projection on upper surface, antennomere X with broad projection at base, antennomere XI constricted at basal third; metaventral processes long, apically broadened; protrochanter with distinct ventral spine, profemur with long and slender ventral spine; protibia with large apical spine; mesotrochanter with multiple protuberances.
Description. Male (Fig. 1B). Body reddish brown, BL 3.19–3.27 mm. Head slightly longer than wide, HL 0.66–0.69 mm, HW 0.63–0.66 mm; each eye composed of about 28 facets; with well-developed ocular canthus. Antennomeres IX–XI (Fig. 3A) forming distinct club, antennomere VII slightly broadened mesally, antennomere IX nearly triangular, with small projection on upper surface, antennomere X with broad projection at base, antennomere XI constricted at basal third. Pronotum (Fig. 3B) longer than wide, PL 0.69–0.72 mm, PW 0.68–0.69 mm, rounded at anterolateral margins, constricted at apical third. Elytra wider than long, EL 0.79–0.84 mm, EW 1.12–1.15 mm. Metaventral processes long, apically expanded (Fig. 3C). Protrochanter (Fig. 3D) with distinct ventral spine, profemur with long and slender ventral spine; protibia (Fig. 3E) with large apical spine; mesotrochanter with three ventral spines, mesofemur with small but distinct ventral spine (Fig. 3F); metatrochanter and metafemur (Fig. 3G) simple. Abdomen broad at base and narrowed apically, AL 1.02–1.05 mm, AW 1.29–1.32 mm. Sternite IX (Fig. 3H) semi-membranous. Length of aedeagus (Figs 3 I–K) 0.67 mm; median lobe strongly asymmetric, parameres short, setose at apex, endophallus composed of two elongate sclerites.
Female. Unknown.
Comparative notes. The new species is placed as a member of the P. walkeri species group (here termed) based on the asymmetrical male antennomere VII. Pselaphodes anjiensis shares with P. nomurai Yin, Li & Zhao, 2010 a general shape of the antennal club and aedeagus, but can be readily separated from the latter by the less distinctly constricted antennomere XI, a much broader antennomere X, lack of a long process at the apicomesal margin of antennomere IX, the non-protruding pronotal anterolateral corners, much longer metaventral processes, and a different spination of the fore and middle legs in the new species.
Etymology. The specific epithet refers to the type locality of the new species, i.e., An’ji County; adjective.
Distribution. China: Zhejiang.
