Type material examined.

Holotype (male): We examined images of the holotype, including the dissected aedeagus. The specimen is from Bolivia (Santa Cruz Department, Gutiérrez Province, Nueva Moka) and deposited in MACN.

Differential diagnosis.

See differential diagnosis for N. duo .

Description.

Aedeagus: (Fig. 25E, F ) Overall shape pear-like, 2.4 × longer than wide; lateral projection on apical region of outer margin of each paramere pointed; at closest point, dorsal inner margins of parameres separated by distance nearly 0.5 × greatest width of a paramere; dorsal plate of median lobe with arms parallel, nearly 0.5 × length of dorsal plate of median lobe; each arm parallel sided, apically rounded; notch between arms very narrow; ventral plate of median lobe triangular, apically rounded, apex extending to base of arms of dorsal plate.

Distribution.

Known only from the type locality in Bolivia (Fig. 29A ).

Habitat.

Nothing is known about the habitat of this species.

Remarks.

This species is known from a single male specimen. We examined images of the type specimen and its aedeagus (Fig. 25E, F ). While we considered that it may in fact refer to N. duo , the differences in the length of the ventral plate of the median lobe of the aedeagus and the disjunct distributions led us to consider them distinct species.
