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 plates, antennae brown to dark brown with paler second and third antennomeres. Pubescence pale golden, moderately long and sparse, not concealing tegument, each individual seta ca. 0.80× as long as second antennomere (Fig. 1b). Dorsal habitus: body shape (Fig. 1b) vaguely similar to L. buyssoni. Clypeus with truncate anterior margin. Dorsal punctures on pronotum rather fine and deep, each puncture separated from another by ca. 1.2–1.6 diameter; space between punctures smooth and shining. Dorsal punctures on elytra rather large, separated by ca. 1.2–1.5 diameter; space between punctures smooth and shining. Ratio LPR1/LELY = 0.50; ratio WPR1/LPR1 = 1.82; ratio WPR2/LPR1 = 1.68; ratio WPR2/WPR1 = 0.93; ratio LELY/WELY = 1.02; ratio WPR1/WPRA = 1.70; ratio WPR1/WELY = 0.92; ratio WPR2/WELY = 0.85. Ventral habitus: combined outer edges of antennal grooves almost straight, parallel-sided along most of length. Prosternal process slightly wider than length of antennal club, with fine and sparse punctation. Male ...
