Diagnosis. This species can be distinguished by its large size, broad, elongate body form ( Fig. 181 ), prosternal process narrowly rounded apically, males with distinct metatibial ventral apical tooth, intercoxal process of first ventrite broadly rounded at base ( Fig. 184 ), and bronze shining surface. The smaller specimens of this species resemble N. elongatum , but can be distinguished from that by the prosternal process narrowly rounded apically ( Fig. 184 ), and the male metatibia with a distinct ventral apical tooth ( Fig. 60 ).

Redescription (modified from Zayas 1988) (male). 7.0–10.0 mm long, 4.5– 5.5 mm wide. Body elongate, slightly convex ( Figs. 181, 182 ). Shining metallic bronze; antennae, mouthparts, and tarsi tending to be the same color as legs. Head densely punctate, largest punctures subequal to a single eye facet, 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 acute median keel raised anteriorly to a point ( Figs. 10, 12 ); ventral portion of eye reaching subgenal sulcus ( Fig. 9 ); postgena without distinct punctures. Dorsal surface of pronotum densely punctate; punctures separated by 1.0–1.5 diameters. Pronotal marginal bead complete laterally, anterior and posterior margins with marginal bead effaced medially; anterior angles of pronotum obtuse, moderately produced and widely rounded apically; lateral edge of pronotum sinuate at base; pronotum evenly convex ( Fig. 183 ). Hypomeron with distinct punctures ( Fig. 27 ). Prosternal process apically rounded narrowly with distinct marginal grooves opposite coxae not joined apically ( Fig. 184 ). Elytral striae present as moderately impressed, small, discontinuous punctures; elytral interstriae densely punctate; scutellary striae 4–10 punctures long; scutellum triangular, normal ( Figs. 181, 183 ). Mesoventrite thin antero-posteriorly, deeply excavate, V-shaped receiving prosternal process; metaventrite subequal in antero-postero length of mesocoxa ( Fig. 184 ). Metathoracic wing fully developed. Legs short, slender, punctate; apical 1/4 of femur reaching beyond edge of elytron; tibiae slightly apically curved ventrally; metatibia with small ventral apical tooth ( Fig. 60 ). Abdominal depressions on 4th and 5th ventrites present as weakly impressed pits ( Fig. 75 ); intercoxal process of first ventrite broadly triangular apically; ventral surface densely punctate, punctures weakly impressed ( Fig. 184 ).

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

Biology. Unknown.

Distribution. This species is endemic to Cuba. It has been taken primarily on Loma del Gato and Pico Turquino in the Sierra Maestra in Santiago de Cuba Province, but has also been taken once in the mountains north of Imias in Guantánamo Province ( Figs. 258 , 267 ).

Zayas Collection Notes. Zayas (1988) described this species from 15 specimens from Cupeyal collected in 1959, however when we visited his collection in January 2008, there were only nine specimens in the collection. The specimen with the red Tipo label is here designated as the lectotype and the remaining eight specimens are here designated as paralectotypes.

Diagnosis. This species can be distinguished by the pronotum, which is more transverse and has four pits, one on each side of the midline anteriorly and one on each side of the midline posteriorly ( Fig. 187 ). It is similar to N. cristalense , but differs from that species by a shorter, broader body, more transverse pronotum, elytra more convex, humeral angle distinct ( Fig. 185 ), prosternal process flat to apex, and entirely black coloration. These two species are extremely difficult to differentiate without looking at the species at the same time.

Redescription (modified from Zayas 1988) (male). 7.5–8.0 mm long, 5.0 mm wide. Body elongate, slightly convex ( Figs. 185, 186 ). Shining black in color; antennae, mouthparts, and tarsi tending to be the same color as the legs. Head moderately punctate, largest punctures subequal in size to a single eye facet; punctures moderately impressed; extremely short golden seta emerging from each puncture. Antenna weakly clavate, nearly filiform; antennomeres 7–10 widened 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 ); ventral portion of eye reaching subgenal sulcus ( Fig. 9 ); postgena without distinct punctures; area laterad gula densely punctate. Dorsal surface of pronotum densely punctate; punctures separated by 0.5–1.0 diameters. Pronotal marginal bead complete laterally, anterior and posterior margins with marginal bead effaced medially; anterior angles of pronotum obtuse, moderately produced and widely rounded apically; lateral edge of pronotum sinuate at base; pronotum evenly convex ( Fig. 187 ). Hypomeron with distinct punctures ( Fig. 27 ). Prosternal process apically rounded, distinct longitudinal marginal grooves opposite coxae joined apically ( Fig. 188 ). Elytral striae not impressed, present as small discontinuous punctures; elytral interstriae densely punctate; scutellary striae 4–10 punctures long; scutellum triangular, normal ( Figs. 185, 187 ). Humeral angle distinct ( Fig. 185 ). Mesoventrite thin antero-posteriorly, deeply excavate, V-shaped receiving prosternal process; metaventrite subequal to antero-postero length of mesocoxa ( Fig. 188 ). Metathoracic wing fully developed. Legs long, slender, densely punctate; apical 1/4 of femur reaching beyond edge of elytron; tibiae slightly curved apically; meso- and metatibia with ventral apical tooth vestigial ( Fig. 61 ). Abdominal depressions on 4th and 5th ventrites present as weakly impressed pits ( Fig. 75 ); intercoxal process of first ventrite broadly triangular apically; ventral surface densely punctate, punctures weakly impressed ( Fig. 188 ).

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

Biology. Unknown.

Distribution. This species is endemic to Cuba. It has only been collected in Cupeyal of Guantánamo Province ( Figs. 258 , 263 ).
