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.
