Differential diagnosis. Laccobius sharmai belongs to the group of species with longitudinal rows of elytral punctures and curved hind tibiae. The rows are glabrous (in contrast to L. shorti sp. nov. and L. silvester sp. nov.), not sulciform near elytral suture (in contrast to L. celsus and L munus ). The apices of parameres are not swollen and their interior margins straight ( Figs. 32-33 ). Other significant distinguishing characters of L. sharmai include the granulate postlabium with setae rising from the punctures between granulation; the first abdominal sternum provided anteriorly with a median process.

Distribution. Nepal.
