Diagnosis. Syngonocoxite short, with a mesal notch at distal margin entirely dividing the plate, a pair of short projections with a short spine at apex; gonostyle large, weakly sclerotized, with a digitiform projection at inner margin bearing a spine at apex, and an additional mesal short projection with a group of four elongated setae; parameres strongly sclerotized; tergite 9 developed at distal ventral corner, with some spines; cercus elongate.

Description. Male. Head. Occiput yellow, setose; mid ocellus absent, lateral ocelli separated from eye margin by a distance smaller than ocellus diameter; ocellar area light brown; front and clypeus yellowish, setose; maxillary palpus light brown, setose, 1+4 palpomeres, increasing in length to apex; labella yellowish, basal article light brownish. Scape and pedicel rounded, yellowish, setose; flagellomeres elongated, basal third brownish, yellowish distally, with scattered setae. Thorax. Pronotum dark yellowish, with some longer and other smaller setae. Scutum mostly brown, with four lighter bands intertwined with brown bands, smaller setae scattered and some stronger acrostical and dorsocentral bristles; scutellum yellowish, with six stronger scutellar bristles and some smaller setae. Pleural membrane light brown; proepisternum, anepisternum and katepisternum light brown, mesepimeron and metepisternum yellowish brown, with darker areas, laterotergite light brown, mediotergite light brown, except ventrally, close to insertion of the abdomen, yellowish brown. Anepisternum and katepisternum bare, laterotergite setose, mediotergite with a mesal and a pair of more lateral tufts of setae. Halter whitish, with scattered setae on pedicel and capitulum. Legs. Fore and mid legs light brown, hind coxa light brown, yellowish basally, hind femur yellowish, with brownish base and apex; tibial spurs 1:2:2, yellowish brown, front spur more than twice the tibia apex. Wing ( Figure 12 ). Length, 2.4–2.6 mm. Wing mostly translucid, brownish maculae similar to C. papaveroi , sp.n., but a continuous macula connecting base of Rs, base of medial fork and r–m, and a light macula over entire distal third of wing. Membrane with macro and mictrotrichiae; humeral cell bare of macrotrichia; basal cell with macrotrichia at distal half. Sc complete, short, reaching C at basal fourth of wing; R1 long, reaching C around distal third of wing; R5 reaching C before apex of M1; C reaching a third the distance between R5 and M1; r–m oblique, longer than base of Rs; M1+2 longer than r–m; medial fork complete, M4 entirely absent; A1 very short, scarcely visible. Abdomen. Abdominal tergites and sternites 1–7 yellowish brown. S8 U–shape, T8 wide and short. Terminalia ( Figure 31 ). Terminalia light brown. Syngonocoxite short, covering anterior half of terminalia, with a pair of short median projections each bearing a short spine. Gonostyle wide, weakly sclerotized, with a long, inner projection with a spine at apex, and a short, lobed projection with some long setae. Parameres present as a pair of long, blade–like, dark sclerites. Aedeagus long, without lateral distal expansions. T9 projected laterally at distal margin, with a number of spiny setae on inner margin of each projection. Cerci simple, elongated.

Etymology. The name of this species is feminine and refers to the type –locality in aposition.

Comments. There is a group of species including C. binocellaris (Edwards) , C. plaumanni Edwards , and C. fuscipennis Edwards , all from the southern range of the Atlantic Forest (including areas in Paraguay and Argentina) to which this species seems to belong. This is shown by the flat, weakly sclerotized gonostyle and the shape of the synsternogonocoxite, with a pair of projections with some slender spines at their apex. C. sapiranga , sp.n. and C. fluminense , sp.n. also belong to this group. The shape of the syngonocoxite and of the gonostyle are unique in this species.
