Diagnosis. This species can be distinguished by the combination of the more elongate and broad body shape ( Fig. 165 View Figs ), more transverse pronotum with less acutely rounded anterior angles ( Fig. 167 View Figs ), antennomeres 7–10 weakly widened apically, and males with an obvious meso- and metatibial tooth ( Fig. 56 View Figs ). This species closely resembles N. darlingtoni   , but can be distinguished from that species by the broader body ( Fig. 165 View Figs ), shallowly excavate mesoventrite ( Fig. 168 View Figs ), and the pronotum with more widely rounded, less produced anterior angles ( Fig. 167 View Figs ). It is also similar to N. altagracia   , but can be distinguished from that by the more transverse pronotum with the anterior angles more obtuse, less produced, and more widely rounded ( Fig. 167 View Figs )

Description (male). 8.5–10.5 mm long, 4.5–6.0 mm wide. Body elongate, moderately convex, broad, tapering weakly at apex ( Figs. 165, 166 View Figs ). Purple to black; antennae, mouthparts, and tarsi tending to be the same color as the legs. Head densely punctate, punctures variable, largest punctures subequal to a single eye facet, lightly to moderately impressed; extremely short golden seta emerging from each puncture. Antenna weakly clavate, nearly filiform; antennomeres 7–10 weakly widened apically, forming a loose, elongate club; apical antennomere

longitudinally ovate; antennomeres 7–11 with stellate sensoria. Mentum with broad median keel raised anteriorly to a point ( Fig. 13 View Figs ); ventral portion of eye reaching subgenal sulcus ( Fig. 9 View Figs ); postgena without circular punctures. Dorsal surface of pronotum scarcely punctate; shagreened. Pronotal marginal bead complete laterally, anterior and posterior margin with marginal bead effaced medially; anterior angles of pronotum right, moderately produced and apically narrowly rounded; lateral edge of pronotum sinuate at base; pronotum evenly convex ( Fig. 167 View Figs ). Hypomeron with distinct punctures. Prosternal process apically rounded; indistinct marginal grooves opposite coxae not joined apically ( Fig. 168 View Figs ). Elytral striae not impressed, present as small discontinuous elongate punctures; punctures separated by 0.5–1.0 diameters; elytral interstriae flat; scarcely punctate; shagreened; scutellary striae long; 4–6 punctures long, nearly reaching the elytral suture; scutellum triangular, normal ( Figs. 165, 167 View Figs ). Mesoventrite thin antero-posteriorly, shallowly excavate, widely U-shaped, receiving prosternal process; metaventrite subequal in antero-postero length of mesocoxa ( Fig. 168 View Figs ). Metathoracic wing fully developed. Legs long, slender, punctate, apical portion of femur reaching beyond elytron; tibiae ventrally apically weakly curved; meso- and metatibia with small, but obvious ventral apical tooth ( Fig. 56 View Figs ). Abdominal depressions on 4th and 5th ventrites present as weakly impressed pits ( Fig. 75 View Figs ); intercoxal process of first ventrite apically rounded; ventral surface densely punctate, punctures weakly impressed ( Fig. 168 View Figs ).

Female. Identical to male, except tibiae straight and meso- and metatibiae lacking ventral apical tooth.

Notes. The specimens of this species vary in size by the locality in which they are found. The specimens collected in Pedernales are larger than those collected in Barahona.

Biology. This species has been taken at light, at night, during the day, by beating dead branches, on logs at night, and under bark in mixed Magnoliaceae   forests.

Distribution. This species is endemic to Hispaniola and is quite widespread in Barahona and Pedernales Provinces of the Dominican Republic ( Figs. 260 View Fig , 266 View Figs ).

Etymology. The species epithet comes from the Latin word mutabilis, meaning changeable, variable or inconstant, referring to the idea that this species is variable in size depending on where it is found.
