( Fig. 16 A−C) by the epigyne with ar entire, recurved and MS subpentagonal. They are distinguished from both species by the spermathecae free, not encapsulated within a sclerotized structure ( Fig. 8E ) (encapsulated in the other species). They are additionally distinguished from N. taino by the ar completely covering the anterior margin of MS (not covering the anterior margin in N. taino ) and from N. toronegro sp. nov. by the ar medially angled ( Fig. 8D ) (evenly curved N. toronegro sp. nov. ). Males are unknown. Etymology The specific name refers to the type locality; noun in apposition.
