Name
Lathrobium pilosum Peng & Li sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
(2 ♂♂). Holotype: ♂, labeled ‘CHINA: Zhejiang Prov. / Qingyuan County / Baishanzu N. R. / 27°45'N, 119°13'E / 22–23.ix.2008, alt. 1,500 m / Tang & Zhang leg.’. Paratypes: 1 ♂, same label data as holotype, but ‘27°44'N, 119°13'E / 21.viii.2004, alt. 1,250–1,650 m / Hu, Tang & Zhu leg.’.
Description
Measurements and ratios:BL 9.10–10.00, FL 4.11–4.17, HL 1.20–1.26, HW 1.39–1.50, PL 1.75–1.79, PW 1.52–1.57, EL 1.11–1.13, HL/HW 0.84–0.86, HW/PW 0.91–0.96, HL/PL 0.69–0.70, PL/PW 1.14–1.15, EL/PL 0.63.
Habitus as in Fig. 1C. Similar to Lathrobium baishanzuense, except for the darker coloration of body, the somewhat larger body size, coarser and sparser punctation on the head and pronotum, and weakly convex lateral margins of pronotum in dorsal view.
Male. Sternite IV (Fig. 5A) with cluster of dense dark setae in large postero-median impression, and posterior margin with 7–9 point-like setae; sternite V (Fig. 5B) similar to sternite IV, but with longer setae in smaller impression and posterior margin with numerous point-like setae; tergite VII (Fig. 5D) strongly transverse, posterior margin weakly concave, pubescence unmodified; sternite VIII (Fig. 5H) with triangular, symmetric emargination and short darkish setae in narrow impression; sternite IX (Fig. 5E) nearly symmetric; aedeagus (Fig. 5F, 5G) with narrow ventral process, broad dorsal plate in lateral view and with single sclerotized apical spine in internal sac.
Female. Unknown.
Distribution
East China: Donggong mountain range.
Etymology
The specific epithet (Latin, adjective: hairy) alludes to the chaetotaxy of the male sternite IV.
Comparative notes
This species is close to Lathrobium tangi sp. n. in sharing a large impression on the male sternite IV and a similar shape of the male sternite VII.In Lathrobium pilosum, the posterior margin of the male sternite VI has several point-like setae, and male sternite VIII is symmetrically emarginate.
