Key to species of Neopedies Hebard, 1931

1. Epiproct triangular with two conspicuous protuberances in the distal region; furculae highly developed, sclerotized and arranged in an inverted V-shape; male cerci subquadragular enlarged in basal and apical region, extremities indented and sclerotized; ancorae developed; lophi triangular with median reentrancy very protruding, distinct undulation in the basal region, sclerotized and posterior projections divergent; female subgenital plate in ventrally with median projection developed, the sides are small and posterior edge slightly sclerotized..........................................................
