Abstract

The genus Heligmomerus Simon, 1892 of the trapdoor spider family Idiopidae is represented by a single species, H. prostans Simon, 1892 in India. Idiops biharicus Gravely, 1915 and I. barkudensis Gravely, 1921 were found to be misplaced in the genus Idiops and transfer to the genus Heligmomerus based on a dorsal saddle-shape depression on tibiae III. The Heligmomerus barkudensis (Gravely, 1921) was previously known only from the type locality but during the recent surveys in Orissa it was sampled from several locations on the mainland in Orissa as well as other islands of Chilika Lake. H. barkudensis is redescribed and natural history notes are provided based on the new specimen collections from the type locality, Barkuda Island and other new localities in Orissa.
