Description
Measurements and ratios:BL 7.23–8.34, FL 3.34–3.72,HL 1.04–1.11, HW 1.05–1.15, PL 1.39–1.48, PW 1.07–1.20, EL 0.93–1.02, HL/HW 0.94–0.99, HW/PW 0.96–0.99, HL/PL 0.75–0.79, PL/PW 1.23–1.30, EL/PL 0.67–0.69.
Habitus as in Fig. 1B. General appearance similar to Lathrobium acutissimum, except for somewhat smaller body size and sparser punctation on head and pronotum.
Male. Posterior margin of sternite VII (Fig. 3A) weakly concave; sternite VIII (Fig. 3B) with symmetrical, subtriangular emargination and darkish setae in large, shallow impression; sternite IX (Fig. 3C) asymmetrical; aedeagus (Fig. 3D, 3E) with slender, ventral process and short, dorsal sclerites.
Female. Posterior margin of tergite VIII (Fig. 3F) nearly truncate; sternite VIII (Fig. 3G) much longer than that of male, posterior margin strongly convex; tergite X (Fig. 3H) slender and not reaching anterior margin of tergite IX (Fig. 3H).
Distribution
Southwest China: Sichuan.
Etymology
The specific epithet of this new species is derived from the type locality “Hailuogou”.
Remarks
The new species resembles Lathrobium zhangi Watanabe & Xiao, 1997 from Yunnan in having the posterior margin of the male sternite VII weakly concave and a similar shape of the male sternite VIII. The new species can be readily distinguished from these species by the broad ventral process of the aedeagus in lateral view. In Lathrobium zhangi, the ventral process of the aedeagus is much narrower in lateral view.
