Diagnosis. This species can be distinguished by the elytral striae deeply impressed ( Fig. 213 View Figs ), hypomeral bead absent to extremely faint, antennomeres 7– 10 enlarged, and the absence of an ocular depression. It most closely resembles N. serratum   , but can be distinguished from that species by the absent to faint hypomeral bead ( Fig. 27 View Figs ) and the thin mesoventrite ( Fig. 216 View Figs ).

Description (male). 4.0– 5.5 mm long, 2.0–3.0 mm wide. Small, body elongate, moderately convex ( Figs. 213, 214 View Figs ). Shining metallic green to purple; antennae, mouthparts, and tarsi ferrugineous. Head densely variably punctate; largest punctures larger than a single eye facet, weakly to moderately impressed; extremely short golden seta emerging from each puncture. Antenna clavate, antennomeres 7–10 transverse, forming a loose club; apical antennomere subcircular; antennomeres 7–11 with stellate sensoria. Mentum with acute median keel anteriorly raised to a point ( Figs. 10, 12 View Figs ). Ventral portion of eye not reaching subgenal sulcus ( Fig. 8 View Figs ); postgena with distinct punctures ( Fig. 12 View Figs ). Dorsal surface of pronotum densely punctate; punctures separated by 0.5–1.5 diameters. Pronotal marginal bead complete laterally, anterior margin with marginal bead effaced medially, posterior margin without marginal bead; anterior angles of pronotum right, weakly produced and widely rounded apically; lateral edge of pronotum evenly curved to base; pronotum evenly convex ( Fig. 215 View Figs ). Hypomeral bead absent to very faint; hypomeron without distinct punctures. Prosternal process apically rounded, with marginal grooves opposite coxae joined apically ( Fig. 216 View Figs ). Elytral striae deeply impressed, present as rows of small punctures separated by 0.5–1.0 3 diameter, with a deeply impressed line through the middle of each puncture row; elytral interstriae roundly convex, sparsely punctate; scutellary striae 4 punctures long; scutellum triangular, normal ( Figs. 213, 215 View Figs ). Mesoventrite thin antero-posteriorly, V-shaped, excavate receiving prosternal process; metaventrite subequal to antero-postero length of mesocoxa ( Fig. 216 View Figs ). Metathoracic wing fully developed. Legs short, punctate; femora reaching beyond edge of elytron; tibia sometimes with weak dorsal longitudinal groove ( Fig. 37 View Figs ); metatibia weakly curved apically, with an obvious tooth at apex; metatibia with small serrations extending from tooth to apical 1/3 its length ( Fig. 66 View Figs ). Abdominal depressions on 4th and 5th ventrites reduced to indistinct slits ( Fig. 74 View Figs ); intercoxal process of first ventrite rounded with apical nipple; ventral surface densely punctate; punctures weakly to moderately impressed ( Fig. 216 View Figs ).

Female. Identical to male, except metatibia straight, lacking ventral apical tooth and serrations.

Biology. This species has been collected at night by light, by day beating, and in flight intercept traps. This suggests that this species flies as it comes to light and has flight wings.

Distribution. This species is endemic to Hispaniola. An extremely long series of this species was taken at the Larimar Mine in Barahona Province in the Dominican Republic. It has also been taken on Mt. Tutu in Barahona Province. Finally, it has been taken on the mine road at 23 and 26 km north of Cabo Rojo in Pedernales Province ( Figs. 260 View Fig , 265 View Figs ).

Etymology. This species is named for Paul E. Skelley, who collected the majority of the specimens.
