Recent taxonomic studies on the genus Wahydra Steinhauser, 1991, have described five new species in the past two years, from high elevations in the Andes Mountains. A markedly distinct species of Wahydra is herein described and illustrated based on a single male specimen from Ecuadorian Andes, Wahydra graslieae A. Warren, Carneiro Dolibaina, sp. nov. The new species is compared with other species of Wahydra, as well as with the somewhat similar species Lerema viridis (Bell, 1942) and Tigasis viridenex (Weeks, 1901).
