Holotype: ♂, labeled ‘'CHIN'A: Sichuan Prov. / Tianquan County / Labahe N. R. / 30°09'N, 102°28'E / 31.vii.2006, alt. 2,400–2,600 m / Hu & Tang leg.’. Paratypes: 1♀, same label data as holotype.
Description
Measurements and ratios:BL 7.02–7.54, FL 2.95–3.06, HL 0.85–0.94, HW 0.88–0.92, PL 1.22–1.25, PW 0.91–0.93, EL 0.78–0.81, HL/HW 0.97–1.02, HW/PW 0.97–0.99, HL/PL 0.70–0.75, PL/PW 1.34, EL/PL 0.64–0.65.
Habitus as in Fig. 1C. Generally similar to Lathrobium acutissimum except for lighter coloration of legs, smaller body size, and somewhat sparser punctation on head and pronotum.
Male. Posterior margin of sternite VII (Fig. 4A) concave and with short, darkish setae; sternite VIII (Fig. 4B) with semicircular, symmetrical emargination and dense, long setae in shallow impression; sternite IX (Fig. 4C) nearly symmetrical; aedeagus (Fig. 4D, 4E) with long, ventral process and thin, dorsal sclerite.
Female. Posterior margin of tergite VIII (Fig. 4F) weakly convex; sternite VIII (Fig. 4G) much longer than that of male, posterior margin strongly convex; tergite IX (Fig. 4H) not separated from tergite X (Fig. 4H).
Distribution
Southwest China: Sichuan.
Etymology
The specific epithet of this new species is derived from the type locality “Labahe”.
Remarks
Lathrobium labahense resembles Lathrobium watanabei Schülke, 2002 in having a similar shape of the male sternite VIII, but can be readily separated by the aedeagus with a much longer ventral process.
