Type Material Examined. HOLOTYPE: Nesocyrtosoma ; celadona; Doyen and Poinar; HOLOTYPE. ( GOPC) .

Diagnosis. This species can be distinguished from all other species in the Serrania species-group by the crenulate lateral edges of the pronotum. This species shares crenulate lateral edges of the pronotum with N. crenulatum , but can be distinguished from that by the smaller size, green rather than purple tinge to the elytra and slightly crenulate lateral edges of the elytra.

Redescription (modified from Doyen and Poinar 1994) (sex unknown). 4.5 mm long, 2.6 mm wide. Small, body elongate, ovate, slightly convex ( Figs. 251, 252 ). Shining green; antennae, mouthparts and tarsi ferrugineous. Head densely punctate; punctures subequal to a single eye facet and moderately impressed. Antenna clavate; antennomeres 7–10 transverse forming a loose club; apical antennomere subcircular. Mentum with acute median keel raised anteriorly to a point ( Figs. 10, 12 ); ventral portion of eye not reaching subgenal sulcus ( Fig. 8 ). Pronotal marginal bead complete laterally, anterior and posterior margins with marginal bead effaced medially, anterior angles of pronotum right, weakly produced and broadly rounded apically; lateral edge of pronotum crenulate; pronotum evenly convex. Prosternal process apically rounded to a point with faint marginal grooves opposite coxae not joined apically ( Fig. 253 ). Elytral striae impressed, present as small discontinuous punctures with a deeply impressed line connecting the rows of punctures; interstriae roundly convex, impunctate, shagreened; scutellary striae 8–10 punctures long; scutellum triangular, normal ( Fig. 251 ). Lateral edge of elytra finely crenulate. Mesoventrite thin antero-posteriorly, deeply excavate, V-shaped, receiving prosternal process; metaventrite subequal to antero-postero length of mesocoxa ( Fig. 253 ). Metathoracic wing fully developed. Legs long, slender; apical 1/4 of femora reaching beyond edge of elytra; protibia straight; meso- and metatibia bowed; apical tarsomere longer than preceding tarsomeres combined ( Fig. 253 ). Intercoxal process of first ventrite broadly triangular apically ( Fig. 253 ).
