Figs 3View FIGURE 3 a–f, 4a –c

Diagnosis. Female. Antennal anellus longer than wide ( Fig. 3eView FIGURE 3); mesepisternum mostly smooth and shiny; protarsal claws falcate; protarsomeres 4 and 5 each with a pair of peg-like spines ventrally ( Fig. 3fView FIGURE 3); median carina of interantennal projection extending to median ocellus ( Fig. 3dView FIGURE 3); scape 6.2–7.1× as long as wide; mesoscutellum flattened ( Fig. 3aView FIGURE 3); metafemur ventrally with 13–15 teeth along outer margin ( Fig. 4aView FIGURE 4); propodeum with a wide and well-defined pentagonal areola medial to adpetiolar area, areola with a T- or Y-shaped median carina at the posterior margin ( Fig. 4bView FIGURE 4).

Description. FEMALE. Length 5.0– 5.3 mm. Color: Predominantly black, with yellow and light brown areas ( Figs 3View FIGURE 3 a–d, 4a), as follows. The following parts yellow: parascrobal area through lower face ( Figs 3c, dView FIGURE 3), pronotal collar posteriorly ( Fig. 3bView FIGURE 3), mesoscutellum laterally, tegula, an irregular spot on distal third of outer face of metafemur ( Fig. 4aView FIGURE 4), tarsi, and petiole (occasionally dark brown). The following parts light brown: profemur apically and mesofemur (sometimes golden brown), outer face of metafemur basally, spot on metatibia basally. Wings lightly infuscate ( Figs 3a, bView FIGURE 3).

Head. Lower face not bulging above clypeus, with shallow umbilicate fovea, interstices narrow and coriaceous ( Fig. 3dView FIGURE 3); parascrobal area densely foveate, interstices coriaceous; median intumescence absent; malar space 0.4× eye height ( Fig. 3cView FIGURE 3), malar sulcus conspicuous, straight, internal carina absent, external carina fine and inconspicuous, complete; gena umbilicate to rugose, genal carina reaching vertex; mandibular formula 2:3; antennal scrobe from smooth and shiny ventrally to coriaceous-strigulate dorsally, and with transverse V-shaped carina below median ocellus ( Figs 3c, dView FIGURE 3); interantennal projection with median carina dorsally, carina extending to median ocellus ( Fig. 3dView FIGURE 3). MOD:POL:APL:OOL = 0.15:0.33:0.11:0.10. Scape 6.2–7.1× as long as wide, with inner face flattened; anellus longer than wide ( Fig. 3eView FIGURE 3); Fu1 about 2× as long as wide, and 1.0× as long as Fu2 length ( Fig. 3eView FIGURE 3).

Mesosoma  . Mesoscutum with interstices coriaceous and dull, narrower than diameter of umbilicate foveae; mesoscutellum flat, frenal carina forming two sublateral lobes; mesopleuron with mesepisternum from smooth and shiny to coriaceous on upper quarter and along the outer margin (except for 3 or 4 foveae dorsally), irregularly areolate-rugulose medially and foveate ventrally; propodeum with a regular median carina, submedian carina absent, anterior costulae incomplete, posterior costulae straight, adpetiolar area with a wide and well-defined pentagonal areola medially, areola with a Y- or T-shaped median carina at the posterior margin, anterosubmedial area sparsely rugose to coriaceous ( Fig. 4bView FIGURE 4); tarsomeres 4 and 5 of all legs with pubescence similar to basal tarsomeres; protarsomeres 4 and 5 each with a pair of distinct peg-like spines ventrally ( Fig. 3fView FIGURE 3); protarsal claws falcate, ventrally with 4 basal spines followed by a tooth-like projection ( Fig. 3fView FIGURE 3); mesocoxa slightly pubescent posteriorly; mesotibial spur 0.9× as long as the width of the mesotibial apex; metacoxa smooth and shiny dorsally, inner face glabrous; metafemur with outer face densely punctate and interstices smooth and shiny, ventrally without inner basal tooth but with 13–15 teeth along outer margin, outer basal tooth the largest and close to second tooth, the latter minute, the third to the tenth teeth subequal and of moderate size ( Fig. 4aView FIGURE 4); metatibia with spine slender and longer than apical width of metatibia; metatarsomere 1 slightly longer than any of tarsomeres 2–5. Fore wing SMV:MV:PMV = 1.76:0.74:0.94.

Metasoma. Petiole about 4.2–4.6× as long as wide, cylindrical ( Fig. 4cView FIGURE 4), with dorsolateral carina along basal third; ventrally without longitudinal carina; hypopygial median projection apically with distinct set of short and appressed bristles, ventrally densely bristly (bristles longer than width of hypopygial projection in lateral view) ( Fig. 4cView FIGURE 4); ovipositor sheath slightly obliquely truncate apically, with some long setae ( Fig. 4cView FIGURE 4).

Biology. Unknown.

Distribution. BRAZIL (Bahia, Paraná, Santa Catarina).

Remarks. Females of C. danunciae  are similar to those of C. quechua  and C. winstonae  (see “Putative Relationships” below), but are distinguished by a longer scape, median carina of interantennal projection extending to the median ocellus ( Fig. 3dView FIGURE 3), and propodeum with a wide and well-defined pentagonal areola medial to the adpetiolar area, the areola with a Y- or T-shaped median carina at the posterior margin ( Fig. 4bView FIGURE 4).

Etymology. This species is named after Dr. Danúncia Urban, eminent hymenopterist and dear professor who recently retired from DZUP.
