Description. Female ( Fig. 1View FIGURE 1). Fore wing length 3.7–5.0 mm.

Head. Head mostly coriaceous, punctate, frons coriaceous to rugose; antenna with 34–36 flagellomeres, first flagellomere 5.0 × as long as width and 1.5 × as long as the second flagellomere; occipital carina complete, meeting hypostomal carina before mandible base and distant from lateral ocelli 1.5 × their diameter; eyes hairy and strongly convergent ventrad ( Fig. 3View FIGURES 3–8); lateral ocellus separated from eye and distance between lateral ocelli by 1.0 × their diameter; tentorial pit touching inner margin of eye; malar space short, base of mandible nearly touching lower eye margin; mandibles short, upper tooth as long as the lower tooth; apical margin of clypeus rounded and weakly convex; gena narrow.

Mesosoma  . Mesosoma  mostly coriaceous, punctate, except lower part of pronotum and upper part of mesopleuron striate and propodeum rugose; epomia present; mesoscutum without notaulus ( Fig. 5View FIGURES 3–8); scutellum without lateral carina; epicnemial carina present, reaching 0.5 posterior margin of pronotum; sternaulus distinct anteriorly ( Fig. 6View FIGURES 3–8); mesopleural fovea strong; propodeum long, with apex projecting between bases of hind coxae less 0.5 × the length of hind coxa, basal area and areola separated by anterior transverse carina, petiolar and superomedia areas not separated and elongate ( Fig. 7View FIGURES 3–8), spiracle small, round and distant from pleural carina by 1.0 × its own diameter; fore wing without areolet, vein cu-a slightly distad Rs&M, vein 2m-cu with one bulla; hind wing with Cu1 and distal abscissa of 1A absent, first abscissa of Rs as long as 1rs-m, four distal hamuli; legs with tarsal claws pectinate only at the base.

Metasoma. Metasoma mostly coriaceous; first tergite smooth at its base and apex, 5.0 × as long as posteriorly broad; second tergite 4.0 × as long as wide, tyridium separated from the base of the second tergite by 4.3 × its length ( Fig. 8View FIGURES 3–8); sixth and seventh tergites deeply emarginate apically; ovipositor 1.3 × as long as the hind tibia.

Coloration. Predominantly black. Mandibles (except their apex), palpi and tegulae yellowish white. Anterior and mid legs with coxa, trochanter and trochantellus yellowish white, last tarsomere brown and remaining segments orange. Posterior legs with coxa and trochanter (except their yellowish white apex) black, trochantellus and tibial spurs yellowish white, femur and tibia orange brown, tarsus brown. Tergites I-III black, tergites II and III apically and laterally orange, and the remaining tergites orange brown to brown. Ovipositor sheaths dark brown. Wings hyaline, pterostigma brown.

Male ( Fig. 2View FIGURE 2). Similar to female in structure and color except: eyes not strongly convergent, sometimes not so hairy, and tentorial pit distant from the inner margin of eye ( Fig. 4View FIGURES 3–8); first flagellomere 3-4 × as long as width; darker abdomen, but tergites II and III orange to orange brown at least laterally.

Distribution. BRAZIL: Goiás, Mato Grosso do Sul, Minas Gerais and São Paulo States ( Fig. 9).

Host. Unknown.

Etymology. The specific name derives from Tupy language (y py = the first) in reference to the fact that this is the first species of the genus to be formally described for Brazil.

Comments. The new species fits well within the diagnosis of the Cymodusa  genus (see Introduction) and seems to belong to the “ melanocera  ” group proposed by Sanborne (1986) with females having eyes very strongly converging ventrad, tentorial pit touching inner margin of eye, and antennal flagellum uniformly black. Cymodusa ypy  sp nov. differs from the similar species, C. nicolei  , and from the other two Neotropical species, C. melanocera  and C. montana  , by the following combination of characters: first flagellomere 5.0 × as long as wide; areolet absent in fore wing; propodeal carination well developed, areola and basal area of propodeum not confluent; tergite II 4.0 × as long as wide and tergites VI and VII deeply emarginate in dorsal view; antenna uniformly black; fore and mid coxae and trochanters light yellow; tergites II and III orange to orange brown, at least laterally. The record of this new species extends significantly the distribution range for the genus in South America, where it was previously only known from Ecuador. In Brazil, Cymodusa ypy  sp nov. occurs in the central and southeastern regions of the country, including areas of Atlantic Forest, Brazilian Savanna (Cerrado) and Pantanal biomes, and is also found in agroecosystems.
