female MCZC specimen with the same label data as holotype. Cardero, tur-;quino, Ote.; G.I. Garcia/ Cardero, Turquino; X-1966; I. GARCIA / Tenebrionidae ; Ident. OHG 871; Genero y especie n. (1 OHGC). 536; Cnodalon ?; ruficorne . (1 Gundlach Collection – IESC).

Diagnosis. This species can be distinguished by the combination of the elongate, less convex body form ( Figs. 225, 226 ), flat dorsal surface of the pronotum ( Fig. 227 ), antennomeres 6–10 apically enlarged ( Fig. 225 ), and the presence of a ventral ocular depression ( Fig. 229 ). It most closely resembles N. larseni , but can be distinguished from this species by having a flat dorsal surface of the pronotum, antennomeres 6–10 weakly transverse, and the presence of a ventral ocular depression ( Fig. 229 ).

Description (male). 4.5–6.0 mm long, 2.5–3.0 mm wide. Body elongate, slightly convex ( Figs. 225, 226 ). Shining black; antennae, mouthparts, and tarsi ferrugineous. Head moderately punctate dorsally; largest punctures subequal to a single eye facet, slightly impressed; extremely short golden seta emerging from each puncture. Antenna weakly clavate, antennomeres 6–10 weakly transverse, forming a loose club; apical antennomere subcircular; antennomeres 6–11 with stellate sensoria. Mentum with acute median keel raised anteriorly to a point ( Figs. 10, 12 ). Ventral portion of eye not reaching subgenal sulcus ( Fig. 8 ); ventral ocular depression present ( Fig. 229 ); postgena with distinct punctures ( Fig. 12 ). Dorsal surface of pronotum moderately punctate; punctures separated by 1.5–0.5 diameters. Pronotal marginal bead complete laterally, anterior margin with marginal bead effaced medially, posterior margin lacking marginal bead; anterior angles of pronotum acute, weakly produced and narrowly rounded apically; lateral edge of pronotum slightly sinuate at apex, then evenly curved to base; pronotum evenly convex ( Fig. 227 ). Hypomeron without distinct punctures. Prosternal process raised mediobasaly, apically rounded, marginal grooves indistinct, not joined apically ( Fig. 228 ). Elytral striae not impressed, present as rows of medium, elongate punctures separated by 0.5–1.0 3 diameter; punctures becoming more elongate towards lateral and apical portion of elytron; elytral interstriae weakly convex, scarcely punctate; scutellary striae 3 punctures long; scutellum triangular, normal ( Figs. 225, 227 ). Mesoventrite broad anteroposteriorly, weakly V-shaped, receiving prosternal process; metaventrite subequal to antero-postero length of mesocoxa ( Fig. 228 ). Metathoracic wing fully developed. Legs long, punctate; femora reaching beyond edge of elytron; tibiae straight ( Fig. 68 ). Abdominal depressions on 4th and 5th ventrites reduced to indistinct slits ( Fig. 74 ); intercoxal process of first ventrite apically rounded; ventral surface densely punctate, punctures weakly impressed ( Fig. 228 ).

Female. Identical to male.

Biology. Unknown.

Distribution. This species is endemic to Cuba and likely to Pico Turquino in the Sierra Maestra of Oriente Province ( Figs. 259 , 264 ).

Etymology. This species is named for Teresa de Zayas Revuelta, the daughter of Fernando de Zayas, in acknowledgment of her role in preserving the Fernando de Zayas Collection since her father’s death in 1983, and for her generous hospitality during our visit to the collection in January 2008.
