Abstract
A new species of long-legged sesarmid crab of the Leptarma leptosoma (Hilgendorf, 1869) species-group is described from mangroves in south-western India. In the general carapace features as well as in the proportions of the long ambulatory legs, Leptarma biju n. sp. is most similar to L. gracilipes (Li, Rahayu & Ng, 2018), from eastern Indonesia and Papua New Guinea, but can easily be distinguished by the structure of the gonopods as well as the leg proportions.
