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

Diagnosis. This species can be distinguished from all other fossil species by the uniform width of the pronotum and elytra until the apical 1/4 of the elytra tapered weakly to become more slender, the anterior angles of the pronotum very broadly rounded, weakly produced, and the lateral edges of the pronotum entirely straight to the apex.

Redescription (modified from Doyen and Poinar 1994) (sex unknown). 6.7 mm long, 3.1 mm wide. Small, elongate oval, moderately convex ( Fig. 257 View Figs ). Elytra shining green. Head densely punctate dorsally; largest punctures larger than a single eye facet, deeply impressed. Dorsal surface of pronotum densely punctate; punctures separated by 0.5–1.0 diameters. Pronotal marginal bead complete laterally, anterior margin with marginal bead effaced medially, posterior margin lacking marginal bead; anterior angles of pronotum nearly obtuse, weakly produced and widely rounded apically; lateral edge of pronotum straight to base; pronotum evenly convex ( Fig. 257 View Figs ). Elytral striae deeply impressed, present as rows of small punctures with a deeply impressed line through the middle of the punctures; elytral interstriae roundly convex; scutellum triangular, normal ( Fig. 257 View Figs ). All femora reaching past edge of elytra. Venter completely obscured by thick layer of amber.
