( Figs. 7 , 17 , 25 , 32 , 40 )

Ceratalictus allostictus Moure, 1950: 318 . Holotype male from Paraguay (MACN), examined.

Diagnosis. In both sexes: lateral angle of pronotum acute, not projected ( Fig.17 ). Female: mesoscutum with punctures of two sizes intermixed, lateral areas with punctures not contiguous, becoming gradually sparsely punctured centrally, and surface between punctures finely micro-reticulate ( Fig.17 ); metapostnotal carinae almost straight, uniformly spaced and not radiating, median carinae always incomplete. Male: metapostnotum as long as metanotum, carinae weakly sinuous; S4 with a central patch of hairs.

Description. Female. Head. Rounded, wider than long. Labrum. Basal elevation very short and restricted to apical part. Clypeus. Punctures coarse, separated by more than 3 puncture diameters in central area, becoming denser laterally; one-third distal with punctures elongate, surface without micro-reticulation. Supraclypeal area. Punctures of variable size, almost absent in central area; surface weakly micro-reticulate with bright appearance. Lower parocular area. Punctures coarse, oblique and contiguous, surface between punctures weakly micro-reticulate, without rugosity. Upper parocular area and frons. Closely punctate especially on frons, surface with micro-reticulations more evident than those of lower parocular area. Preoccipital ridge carinate not lamellate. Mesosoma. Pronotum. Lateral angle acute. Mesoscutum. Punctures on lateral part of mesoscutum not contiguous becoming gradually spaced centrally, punctures of two diameters intermixed, separated by 2–3, rarely 1puncture diameter; surface between punctures microreticulate. Mesoscutellum. Punctures irregularly spaced, finer than those of mesoscutum, and coarser punctures more concentrated in posterior margin, surface between punctures micro-reticulate and without rugosity. Metapostnotum. Semicircular in outline in dorsal view, subequal to mesoscutellum in length, weakly concave with apex not acuminate, metapostnotal carinae almost straight, separated by 1 carina width and not radiating to the apex, median carinae never complete. Lateral surface of propodeum. Contiguous punctures giving a finely rugulose appearance, 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. T1. Punctures distributed over the whole disc, separated by more than 3 puncture diameters, becoming sparser in middle part; surface smooth and bright. T2. Punctures separated by at least 2 puncture diameters, surface lineolate without rugosity. Body color. Apical one-third of clypeus black; head and mesosoma bright green; legs amber, fore and hind coxa and fore femur with green highlights; metasoma green, posterior marginal areas of terga gradually becoming light brown, sometimes with a narrow stripe; body setae white, except for some yellow setae on basitarsus and metassomal terga. Measurements. Abl: 5–6; mwl: 4.0–4.4; mhw: 1.6–1.7; mhl: 1.4–1.6; mmw: 1.0–1.3.

Male. Same as the female except for the following features. Head. Clypeus. Punctures of variable diameters, separated by at least 1 puncture diameter, uniformly distributed, surface between punctures smooth. Lower parocular area. Punctures separated by at least one puncture diameter, surface smooth and bright, with some long plumose setae. Frons and upper parocular area. More densely punctate than lower parocular area. Antennae. Flagellomeres almost straight. Mesosoma. Mesoscutum. Disc punctures uniformly distributed, surface between punctures smooth and bright, anterior part of median line not depressed. Mesoscutellum. Punctures with irregular size and distribution; surface smooth and bright. Hind tibia. Ventral surface with row of setae approximately two-thirds of tibial diameter. Metapostnotum. Concave, with carinae weakly sinuous, separated by more than one carina width. Lateral surface of propodeum. Densely punctate, surface slightly rugulose on anterior part, without micro-reticulation. Posterior surface of propodeum. Upper punctures similar to lateral, surface with rugulose appearance on lower part, erect setae branched. Metasoma. T1. Disc punctures separated by more than 2 puncture diameters; surface weakly lineolate but bright appearance. T2. Disc punctures separated by at least 3 puncture diameters; surface lineolate. S4. Not strongly setose on lateral surface, centrally with a patch of setae. S5. Not strongly setose; centrally with transverse thickening. S7. Apical margin with very short median process. S8. Apical margin centrally with distinct projection and bearing long setae. Genitalia. Inner lobe of ventral process of gonostylus spatulate and apically directed, with long setae on apical part of inner surface; dorsal lobe absent; parapenial lobe present; gonapophysis not expanded laterally. Body color. Clypeus without black stripe; coxae, trochanters and femora with metallic green highlights, tibiae light brown, tarsi lighter than tibiae; disc of T2–T5 somewhat darkened centrally; body setae white with some yellow reflection, leg setae light yellow, some darkened setae on terminal metasomal terga. Measurements: Abl: 6–7; mwl: 4.2–4.6; mhw: 1.6–1.7; mhl: 1.4– 1.6; mmw: 1.0– 1.2.
