Abstract: Helotrephes nainamalaii sp. nov. from Meghalaya, India is described.
Representatives of Helotrephes are so far known from southern China, Southeast
Asia and Sundaland. The unexpected first record of Helotrephes from India
expands their distribution more than 1,000 kilometres westward. The new species
belongs to the H. australis species-group which is widespread in southern China
and Southeast Asia. Helotrephes nainamalaii sp. nov. can be identified by the
presence of a sub-basal protrusion on the genal plate, a characteristic apical
hook on the aedeagus, and peculiarly shaped ventromedian carinae. The
description is supplemented by a key to the species of the Helotrephes australis
species-group. Tiphotrephes indicus (Distant, 1910) is recorded from Meghalaya
for the first time. A check-list of Helotrephidae in India is given.
