Hind wings reduced. Protarsi without sexual dimorphism, moderately dilated in both sexes. Abdomen broader than elytra; punctation very fine and dense, slightly less dense on posterior than on anterior ter- gites; interstices with fine and shallow, or almost obso- lete microsculpture; posterior margin of tergite VII with- out palisade fringe; posterior margin of tergite VIII con- vex. S: sternite VII with shallow median impression poste- riorly, with sparse unmodified pubescence, and with weak- ly concave posterior margin (Fig. 19); sternite VIII with narrow median impression posteriorly, this impression with distinctly modified, short and stout black setae, pos- terior excision moderately deep, relatively narrow, and al- most V-shaped (Fig. 20); aedeagus mm long, ventral process deeply bifid, of characteristic shape (Figs 21-22). Comparative notes. Lobrathium bicornutum is readily distinguished from the similarly large L. brunneum by the much smaller eyes, much shorter elytra, reduced hind wings, the absence of a palisade fringe at the posterior margin of the abdominal tergite VIII, and by the male sex- ual characters. Distribution and natural history. The type locality is sit- uated in Taplejung district, eastern Nepal (Fig. 23). The specimens were collected in a mature mixed deciduous forest at an altitude of 2300-2500 m. The holotype is ten- eral. Bonn zoological Bulletin 61(1): 49-128 ©ZFMK.
