Type Material. Not seen. Holotype from Dominican amber; deposited in SMNS; Inv. No. Do-3240-M-1.
Diagnosis. This fossil species can be distinguished from all other fossil species by the combination of its larger size (5.0 mm) and the completely unmargined posterior margin of the pronotum. This species most closely resembles { N. minisculum, but can be distinguished from it by its larger size and having the apical six anntenomeres enlarged, forming a loose, elongate club. The description does not provide any other characters that make this species unique from the others, and without studying the holotype, no other diagnostic characters can be provided at this time.
Redescription (based on Kaszab and Schawaller 1984) (sex unknown). 5.0 mm long. Small, elongate. Shining green; legs dark brown with lighter tarsi. Head densely punctate; punctures smaller than a single eye facet. Antenna weakly clavate, nearly filiform; antennomeres 6–11 weakly widened apically, forming a loose, elongate club; apical antennomere longitudinally ovate. Pronotal marginal bead complete laterally, anterior and posterior margins with marginal bead absent, anterior angles of pronotum obtuse, weakly produced and broadly rounded apically; lateral edge of pronotum evenly curved to base; pronotum evenly convex. Prosternal process apically rounded. Elytral striae present as small discontinuous punctures with a deeply impressed line connecting the rows of punctures; interstriae roundly convex, impunctate; scutellary striae 4 punctures long; scutellum triangular, normal. Legs long, slender; apical portion of femora reaching beyond edge of elytra; apical tarsomere longer than preceding tarsomeres combined.
