Differential diagnosis. Laccobius munus belongs to the group of species with curved hind tibiae and longitudinal rows of elytral punctures. The rows are glabrous (in contrast to L. shorti sp. nov. and L. silvester sp. nov.) and sulciform only near the elytral suture (in contrast to L. celsus and L sharmai ). Apices of parameres are not swollen and with inner margin excised ( Figs. 23-26 ). Other distinguishing characters of L. munus include large eyes with the interocular space scarcely wider than one eye diameter, the flat postlabium without punctures, and the median carina on ventrite 1.

Distribution. Nepal.
