New Species

Nesocyrtosoma fernandoi Hopp and Ivie   , New Species ( Figs. 194–199 View Figs , 264 View Figs )

Type Material. HOLOTYPE: Sex unknown. ‘‘Gacunagaua; June-33; Zayas/ HOLOTYPE; Nesocyrtosoma   ; fernandoi Hopp   ; det. K. J. Hopp 2008’’ ( FZMC).

Notes. This species is described from one specimen in the FZMC, which could not be borrowed and was only studied on-site. The photographs of this species were taken with MiScope H   .

Diagnosis. This species can be distinguished from all other species, particularly the other Serrania species-group species   , by the combination of its large size, the broad, elongate body form, long scutellary striae ( Fig. 196 View Figs ), and the presence of a ventral ocular depression ( Fig. 197 View Figs ). This species most closely resembles N. guerreroi   , but can be distinguished from that by having a thin mesoventrite antero-posteriorly ( Fig. 198 View Figs ).

Description (sex unknown). 6.0 mm long, 3.0 mm wide. Body elongate, slightly convex ( Figs. 194, 195 View Figs ). Shinning greenish-purple; antennae, mouthparts, and tarsi ferrugineous. Head moderately punctate dorsally; largest punctures subequal to a single eye facet; 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 raised anteriorly to a point ( Figs. 10, 12 View Figs ). Ventral portion of eye not reaching subgenal sulcus ( Fig. 8 View Figs ); ventral ocular depression present ( Fig. 197 View Figs ). 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 without marginal bead; anterior angles of pronotum acute, weakly produced and apically narrowly rounded; lateral edge of evenly curved to base; pronotum evenly convex ( Fig. 196 View Figs ). Hypomeron without distinct punctures. Prosternal process apically rounded, marginal grooves opposite coxae indistinct ( Fig. 198 View Figs ). Elytral striae not impressed, present as rows of small punctures separated by 0.5–1.0 3 diameter; elytral interstriae flat, impunctate; scutellary striae 6–8 punctures long scutellum triangular, normal ( Figs. 194, 196 View Figs ). Mesoventrite broad antero-posteriorly, Ushaped, receiving prosternal process; metaventrite subequal to antero-postero length of mesocoxa ( Fig. 198 View Figs ). Metathoracic wing fully developed. Legs long, punctate, short golden seta emerging from each puncture; femora reaching beyond edge of elytron; tibiae straight. Abdominal depressions on 4th and 5th ventrites reduced to indistinct slits ( Fig. 74 View Figs ); intercoxal process of first ventrite broadly rounded apically; ventral surface densely punctate, punctures moderately impressed ( Fig. 198 View Figs ).

Biology. Unknown.

Distribution. This species is endemic to Cuba and is only known from the type locality of Cumanayagua (which may not be correct as the label was extremely difficult to read and could barely be interpreted by Teresita Zayas) ( Figs. 199 View Figs , 264 View Figs ).

Etymology. This species is named for Fernando de Zayas, a Cuban entomologist who described several species of Nesocyrtosoma   . The single specimen from which this species is described was discovered in the FZMC.
