Grismado, Cristian J. & Ramírez, Martín J., 2013, The New World Goblin Spiders Of The New Genus Neotrops (Araneae: Oonopidae), Part 1, Bulletin of the American Museum of Natural History 2013 (383), pp. 1-150 : 7-8

The darwini Group

DIAGNOSIS: Copulatory bulb of males elongated, with the embolus accompanied by only a single, forwardly directed, nearly straight conductor, without additional distal apophysis. Tarsi I–II of females much shorter than the metatarsi, which have four pairs of ventral macrosetae (as in fig. 4F–G).

This group includes the type species and the closely related N. tucumanus ; it seems to be restricted to the southern part of the distributional range of the genus, in Argentina and adjacent Uruguay.
