DIAGNOSIS: Females resemble those of N. grismadoi in having an enlarged but membranous anterior receptaculum and boomerang-shaped apodemes of the postepigastric scutum, but have a much larger anterior sclerotization on the anterior receptaculum (figs. 697, 698).

MALE: Unknown.

FEMALE (PBI_OON 443, figs. 689–698): Total length 1.54. Posterior eye row straight from above; PLE-PME separated by less than PME radius. Sternum surface smooth. Leg spination: tibiae IV v0-0-2; metatarsi IV v0-0- 1p. Anterior receptaculum enlarged, occupying most of distance between epigastric furrow and pedicel, with wide anterior sclerotization (figs. 697, 698).
