Lamiogethes hastipenis sp. n. (Figs. 1b, 2 c–d, 3e, 5) Diagnosis. Vaguely similar in external body shape and color to the rare Palearctic species L. buyssoni (Brisout de Barneville, 1882) (in the L. difficilis species group: Audisio 1993). Male protarsi wide, but markedly narrower than in the closely related L. falcatus sp. n., ca. 0.9× as wide as maximum width of the antennal club (Figs. 1b, 3e), ratio WFTA/LFTA ≈ 0.28. Male metatibiae normally shaped, not arcuately sinuate along inner edge (Fig. 1b) and rather rectilinear along most of their outer edge. Male genitalia distinctively shaped, with elongate, subparallel-sided and deeply incised tegmen (Fig. 2c), aedeagal median lobe peculiarly large,>3× longer than wide, maximum width proximad, and peculiar, sword-tip-shaped distal apex (Fig. 2d), similar to L. falcatus sp. n. Description. Size (male holotype): body length 2.30 mm, width 1.32 mm. Body color and pubescence: uniformly dark brown, tegument shiny. Legs brown to dark brown, with paler tarsal ... : Published as part of Liu, Meike, Yang, Xingke, Huang, Min, Cline, Andrew Richard, Sabatelli, Simone & Audisio, Paolo, 2020, Five new species of Lamiogethes Audisio & Cline from China (Coleoptera Nitidulidae: Meligethinae), pp. 63-76 in Zootaxa 4728 (1) on page 67, DOI: 10.11646/zootaxa.4728.1.3, http://zenodo.org/record/3614537 ...
