( Figs. 11 View FIGURES 7 – 12 , 29 View FIGURES 25 – 31 , 34 View FIGURES 32 – 38 , 40 View FIGURES 39 – 41 )

Diagnosis. In both sexes: lateral angle of pronotum strongly acute and projected; metapostnotum semicircular, as long as mesoscutellum, concave with apex acuminate. Female: mesoscutal disc with median strip along median line with punctures separated by 1–3 puncture diameters, surface between punctures strongly micro-reticulate; metapostnotum with carenae reaching edge posteriorly, median carinae branched; surfaces of T 1 and T 2 lineolate, discs darkened. Male: metapostnotum with carinae strongly sinuous; S 4 with a central patch of hair as in C. psoraspis ( Fig. 5 View FIGURES 3 – 6 ).

Description. Female. Head. Rounded, wider than longer. Labrum. Basal elevation very short and restricted to apical portion. Clypeus. Punctures coarse, separated by 1 puncture diameter in central area, becoming denser laterally; one-third distal with punctures elongate, surface micro-reticulate. Supraclypeal area. Puncture of variable size, irregularly spaced centrally; surface micro-reticulate, not bright. Lower parocular area. Punctures oblique and contiguous, surface slightly rugulose near antennal sockets. Upper parocular area and frons. Punctures oblique on upper parocular and contiguous on frons, surface rugulose on upper parocular. Preoccipital ridge. Small, not lamellate. Mesosoma. Pronotum. Lateral angle strongly acute and projected. Mesoscutum. Mesoscutal disc with median strip along median line with punctures separated by 1-3 puncture diameters, lateral areas with punctures contiguous, surface between punctures strongly microreticulate. Mesoscutellum. Punctures finer than those of mesoscutum, surface with rugulose appearance in posterior margin. Metapostnotum. Semicircular in outline in dorsal view, as long as mesoscutellum, concave with apex acuminate, metapostnotal carinae almost straight reaching edge posteriorly, separated by 1 carina width, median carinae branched. Lateral surface of propodeum. Closely punctate, punctures finer than those of mesepisternum, surface rugulose on posterior part, without scattered large punctures, micro-reticulation not evident. Posterior surface of propodeum. Finely and closely punctate, with scattered coarser punctures intermixed, surface weakly roughened and bright. Metasoma. T 1. Fine punctures distributed over the whole disc, separated by more than 3 puncture diameters, becoming more sparsely punctured in middle portion; surface lineolate but bright appearance. T 2. Punctures separated by at least 2 puncture diameters, becoming more sparsely punctured in apical part, surface smooth. Body color. Apical half of clypeus black; head and mesosoma bright green; legs brown, fore coxa and femur and hind coxa with green highlights, tibiae and tarsi brown; discs of T 1 and T 2 with small dark spot, posterior marginal areas of terga with a narrow light brown stripe; body setae white, except for some yellow setae on basitarsus and metasomal terga, and darkened setae on T 4 –T 5. Measurements. Abl: 7; mwl: 4.8; mhw: 1.8; mhl: 1.6; mmw: 1.4.

Male. Same as the female except for the following features. Head. Clypeus. Punctures of variable size, uniformly distributed, surface smooth and bright. Lower parocular area. Punctures separated by 1 puncture diameter, surface micro-reticulate but bright appearance. Frons and upper parocular area. More densely punctate than lower parocular area, region between the antennal alveolus more finely punctate than laterally; several plumose setae on frons. Antennae. Flagellomeres almost straight. Mesosoma. Mesoscutum. Disc punctures uniformly distributed, surface bright but with micro-reticulations in central area; anterior part of median line weakly depressed. Mesoscutellum. Punctures separated by 1–2 puncture diameters, surface smooth and bright, rugulose on posterior margin. Hind tibia. Ventral surface with row of setae about as long as width of tibia. Metapostnotum. Concave and apex acuminate, metapostnotal carinae strongly sinuous, separated by 1 carina width. Lateral surface of propodeum. Punctures contiguous, finer than those of mesepisternum, surface slightly rugulose on anterior margin and without micro-reticulation. Posterior surface of propodeum. Punctation similar to lateral surface. Metasoma. T 1. Punctures separated by 2-3 puncture diameters, surface lineolate but bright apperarance. T 2. Similar to T 1, surface weakly lineolate. S 4. Not strongly setose on lateral surface, apically with a patch of long setae. S 5. Not strongly setose; centrally with transversal sclerotinized thickening. S 7. Apical margin with very short median process. S 8. Apical margin centrally with distinct projection and bearing long setae. Genitalia. Inner lobe of ventral process of gonostylus spatulate and apically directed, with some long setae on apical portion of inner surface; dorsal lobe absent; parapenial lobe present; gonapophysis not strongly expanded laterally. Body color. Clypeus without black stripe; legs brown, coxae, trochanters and femora with metallic green highlights, tibiae and tarsi brown; disc of T 2 –T 5 darkened with bluish reflections, posterior marginal areas of terga light brown; body setae white with some yellow reflection, darkened setae on terminal metasomal terga. Measurements: Abl: 7; mwl: 4.9– 5.1; mhw: 1.7–1.9; mhl: 1.6–1.7; mmw: 1.3–1.4.

Type material. Holotype male ( DZUP): “ DPTO ZOOL \ UF-PARANÁ” “ SANTA TERESA – ES\ BRASIL 18-23 /XII/ 1967 \ C. T. & C. Elias”. Paratypes: one male and one female with same data ( DZUP). Etymology. From a Latin term, the name refers to acuminate apex of metapostnotum.
