Type material

(1 ♂, 2 ♀♀). Holotype: ♂, labeled 'CHINA: Fujian Prov. / Mingxi County / Mt. Junzifeng / 26°34'N, 117°16'E / 7.viii.2008, alt. 1,400 m / Qi & Yin leg.'. Paratypes: 2 ♀♀, same label data as holotype.

Description.

Measurements and ratios:BL 7.78-9.73, FL 3.77-4.05, HL 1.11-1.13, HW 1.24-1.26, PL 1.48-1.54, PW 1.30-1.33, EL 0.93-0.96, HL/HW 0.90, HW/PW 0.95, HL/PL 0.73-0.75, PL/PW 1.14-1.16, EL/PL 0.62-0.63.

Habitus as in Fig. 1B. General appearance similar to that of Lathrobium daicongchaoi , except for the darker coloration, somewhat larger body size, denser punctation on head and pronotum, and the weakly convex lateral margins of pronotum in dorsal view.

Male. Sternite V (Fig. 3A) with darkish setae in postero-median impression, and posterior margin with several point-like setae; sternite VI (Fig. 3C) similar to sternite V, but with much fewer point-like setae; posterior margin of sternite VII (Fig. 3E) weakly concave; sternite VIII (Fig. 3G) with subtriangular, weakly asymmetric emargination and short darkish setae in the narrow median impression; sternite IX (Fig. 3H) nearly symmetric; aedeagus (Fig. 3I, 3J) with long ventral process and short dorsal sclerite.

Female. Posterior margin of tergite VIII (Fig. 3B) broadly convex; sternite VIII (Fig. 3D) longer than that of male, middle of apical margin with obtuse projection; tergite X (Fig. 3F) broadly convex apically and not reaching anterior margin of tergite IX (Fig. 3F).

Distribution.

East China: Fujian.

Etymology.

The specific epithet is derived from Fujian Province, where the type locality is situated.

Remarks.

The new species can be separated from other East Chinese Lathrobium species by the morphology of the aedeagus, as well as by the presence of point-like setae at the posterior margin of the male sternite V and by the presence of short dark setae in the narrow postero-median impression of the male sternite VIII.
