Type material.

Holotype (male): "BOLIVIA: Beni Department/ Cercado Province/ 9.5 km N. of Trinidad/ 14°46'34"S, 64°58'00"W / 17.vi.1999, leg. K.B. Miller" (SEMC). Paratype (1 ex.): same data as holotype (1, SEMC).

Differential diagnosis.

The aedeagus of this species is most similar to N. yora , with which it shares a similar overall form. In N. yora the dorsal plate of the median lobe is thinner along its neck, and the arms of the apical fork are narrower and parallel sided (Fig. 26A View Figure 26 ), while they are wider and more curved in N. mojenos (Fig. 26D View Figure 26 ). The outer margins of the parameres are also more sinuate in N. mojenos , while straight in N. yora .

Description.

Body length 7.2-7.3 mm. Coloration: Dorsal surfaces brown, with slightly paler (orange) clypeus, labrum, and margins of pronotum and elytra. Head: Maxillary palps nearly 1.3 × longer than width of head, uniformly orange in color. Thorax: Ground punctation on pronotum and elytra dense and very shallowly impressed. Elytra without rows of serial punctures, each with very faint rows of scarce and weakly marked systematic punctures on lateral surface of elytron. Prosternum flat. Posterior elevation of mesoventrite elevated as a triangular pyramid, with posterior face somewhat bisinuate and medial longitudinal ridge extending anteriorly (resembling a nose). Abdomen: Apical emargination of fifth ventrite relatively deep, U-shaped. Aedeagus: (Fig. 26D-F View Figure 26 ) Overall shape pear-like, 2.8 × longer than wide, with outer lateral margins of parameres slightly sinuate along second 1/3; lateral projection on apical region of outer margin of each paramere pointed and ventrally directed; at closest point, dorsal inner margins of parameres separated by distance slightly narrower than greatest width of a paramere; dorsal plate of median lobe with neck 0.3 × as broad as base; arms of dorsal plate of median lobe slightly converging, nearly 0.15 × length of dorsal plate of median lobe; each arm widened near apical 1/3, then strongly narrowing, forming medially and dorsally pointed apex; notch between arms at base narrower than base of an arm; ventral plate of median lobe weakly sclerotized, triangular, rounded at apex, apex extending to mid-length of neck of dorsal plate; basal piece 0.3 × length of a paramere. In lateral view, aedeagus with ventral outline of parameres 3.8 × longer than greatest width near base; dorsal outline of aedeagus in lateral view nearly straight along basal 2/3.

Etymology.
