Diagnosis. This species is extremely variable in size, but similar to N. merkli   . It can be distinguished from that and all other species by the combination of the weakly produced, obtuse, and widely rounded anterior corners of the pronotum ( Fig. 134 View Figs ), the broad U-shaped mesoventrite ( Fig. 135 View Figs ), and the small, discontinuous, weakly impressed elytral punctures.

Description (male). 4.5–7.0 mm long, 2.5–4.5 mm wide. Body short, moderately convex ( Figs. 132, 133 View Figs ). Shining darkly ferrugineous to black; antennae, mouthparts and tarsi ferrugineous. Head densely punctate dorsally; punctures smaller than a single eye facet and weakly impressed; extremely short golden seta emerging from each puncture; head often appearing smooth. Antenna clavate; antennomeres 7–10 transverse forming a loose, elongate 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 without distinct punctures. Dorsal surface of pronotum lightly punctate, often appearing smooth. Pronotal marginal bead complete laterally, anterior margin with marginal bead effaced medially, posterior margin lacking marginal bead; anterior angles of pronotum obtuse, weakly produced and widely rounded apically; lateral edge of pronotum evenly curved to base; pronotum evenly convex ( Fig. 134 View Figs ). Hypomeron lacking distinct punctures. Prosternal process apically rounded with marginal grooves opposite coxae joined apically ( Fig. 135 View Figs ). Black, except sometimes under a microscope with light elytra appearing darkly ferrugineous with rows of black squares following elytral striae; elytral striae present as small, discontinuous weakly impressed punctures, punctures closely spaced creating the appearance of a complete weakly impressed striae; elytral interstriae flat, scarcely punctate; scutellary striae short, 3–4 punctures long, scutellum triangular, reduced ( Figs. 132, 134 View Figs ). Mesoventrite broad antero-posteriorly, weakly excavate, Ushaped receiving prosternal process; metaventrite,1/2 antero-postero length of mesocoxa ( Fig. 135 View Figs ). Metathoracic wing vestigial. Legs short, punctate; apical portion of femora reaching beyond edge of elytra; metatibia slightly apically curved ventrally with small tooth proximad apex ( Fig. 49 View Figs ). Abdominal depressions on 4th and 5th ventrites reduced to slightly impressed slits ( Fig. 74 View Figs ); intercoxal process of first ventrite broadly rounded apically; ventral surface densely punctate, punctures weakly impressed ( Fig. 135 View Figs ).

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

Biology. This species has been collected under bark and by beating. It has also been collected at blacklight, but this species lacks flight wings and either crawled to the light or was coincidentally at the collection site.

Distribution. This species is endemic to Hispaniola and has been collected primarily in the Sierra de Bahoruco and Las Abejas in Pedernales Province. It has also been collected in the Sierra Martin Garacia in Azua Province of the Dominican Republic ( Figs. 260 View Fig , 264 View Figs ). It has also been collected in Haiti, on Mt. Cabaio and Morne d’Enefer ( Figs. 261 View Fig , 264 View Figs ).

Etymology. This species is without decoration, and is thus called simplex   (in this case, simplex   is an invariant adjective).
