Ceratalictus nitidus n. sp.

( Figs. 13 , 21 , 41 )

Diagnosis. Female: lateral angle of pronotum acute and projected; mesoscutal disc with punctures separated usually by one puncture diameter, surface between punctures strongly micro-reticulate ( Fig. 21 ); metapostnotum as long as mesoscutellum, almost straight, its posterior edge slightly produced upward, with median carinae branched and reaching edge posteriorly; surfaces of T1 and T2 smooth, discs bright.

Description. Female. Head. Rounded, wider than longer. Labrum. Basal elevation very short and restricted to apical portion. Clypeus. Punctures coarse, separated by 2-3 puncture diameters in central area, becoming denser laterally; one-third distal with punctures elongate, surface weakly micro-reticulate. Supraclypeal area. Sparsely punctate on central area, punctures finer than those of lower parocular, surface weakly micro-reticulate with bright appearance. Lower parocular area. Punctures coarse and almost contiguous, surface between punctures micro-reticulate, without rugosity. Upper parocular area and frons. Closed punctate especially on frons, punctures oblique near to antennal sockets. Preoccipital ridge. Small, not lamellate. Mesosoma. Pronotum. Lateral angle acute and projected. Mesoscutum. Disc with punctures separated by usually 1 puncture diameter in central area, becoming denser towards to parapsidal lines, punctures contiguous on lateral part of mesoscutum, surface strongly micro-reticulate. Mesoscutellum. Punctures contiguous, finer than those of mesoscutum, surface between punctures micro-reticulate, weakly roughened near posterior margin. Metapostnotum. As long as mesoscutellum, almost straight, its posterior edge slightly produced upward, metapostnotal carinae branched medially, separated by 1 carina width, reaching edge posteriorly. Lateral surface of propodeum. Punctures contiguous, finer than those of mesepisternum; surface weakly roughened on posterior part, without scattered large punctures, microreticulation not evident. Posterior surface of propodeum. Finely and closely punctate, with scattered coarser punctures intermixed, surface weakly roughened and bright. Metasoma. T1. Punctures with irregular size and distribution over the whole disc, usually separated by 1-3 puncture diameters, becoming more sparsely punctured in central area, surface between punctures smooth and bright. T2. Punctures separated by 2-3 puncture diameters, becoming more sparsely punctured in apical part; surface lineolate but bright appearance. Body color. Apical half of clypeus black; head and mesosoma bright green; legs brown; coxae, fore and hind trochanters and fore femur with green highlights; discs of T1–T2 green with bright reflections, posterior marginal areas of terga with small light brown stripe; body setae white, except for some yellow setae on basitarsus and metasomal terga, brown on T4–T5. Measurements. Abl: 6; mwl: 4.4–4.5; mhw: 1.7–1.8; mhl: 1.4–1.7; mmw: 1.1–1.4.

Male unknown.

Type material. Holotype female ( DZUP): “FOZ do IGUAÇU – PR\ Brasil 16 XII 1965 \ V. Graf – L. Azevedo". Paratypes. ARGENTINA, Iguassu: one female ( FZRS), "Puerto Iguazu\ Arg. 10.4/1986\ Wittmann leg.". BRASIL, Paraná: one female with same data of Holotype; one female ( DZUP), "FOZ DO IGUAÇU\ Paraná BRASIL \ 11.XII.1966 \ Exc. Dept. ZOO". São Paulo: one female ( DZUP), “ DPTO ZOOL \ UF- PARANÁ” “Cajuru – SP\ 30/XII/85 \ Moure & Camargo col.".

Etymology. From Latin term that means shiny or bright, in reference to its bright reflections compared with C. culminis n. sp.
