Abdomen: Lacking ornamental setulae; sternum 6 slightly enlarged, 7 th segment rotated about 90°, 8 th segment a thin sclerotised ring, rotated another 90°.

Notes: In this new species segments 7 and 8 are probably involved in the torsion of the terminalia. The shape of the terminalia indicates a relationship to N. phoenimimos Quate & Alexander, 2000 , which is also known from Colombia. The inner appendage on the gonostylus of N. cancer sp. n. distinguishes these species.
