Description. Male. Head. Occiput yellowish; mid ocellus absent, lateral ocelli separated from eye margin by a distance smaller than ocellus diameter, ocellar region light brown; front and clypeus yellowish, setose. Maxillary palpus brownish yellow, 1+4 palpomeres, palpomere increasing in length to apex. Scape and pedicel rounded, yellowish, bearing scattered setae; flagellomeres longer than wide, whitish, except for basal fourth, brown. Thorax. Pronotum yellowish, with some longer and other smaller setae. Scutum light brown, with four lighter, whitish yellow longitudinal bands intertwined with brown bands, smaller setae scattered and some stronger acrostical and dorsocentral bristles; scutellum yellowish, brownish at posterior margin, four strong scutellar bristles and some smaller setae. Pleural membrane whitish. Proepisternum, anepisternum, katepisternum, mesepimeron and metepisternum light yellowish, laterotergite yellowish, except for brownish dorso–posterior corner, mediotergite brownish, except for the yellowish ventral and lateral margins. 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 on capitulum. Legs. Legs mostly yellowish, except for brownish front coxa, apex of mid and hind femora, and front tibia; tibial spurs 1:2:2, light brown, front spur more than twice the width of tibia apex. Wing ( Figure 9 ). Length, 2.0 mm. Wing mostly translucid, with a brown macula around base of Rs and r–m, and other maculae around base of medial fork, at entire apical third of wing, and distally across anal lobe. Membrane bearing macrotrichia and microtrichae; humeral cell entirely bare of macrotrichia; basal cell almost entirely devoid of macrotrichia. Sc complete, very short, reaching C at basal fifth of wing; R1 reaching C around the distal third of wing; R5 reaching C before apex of M1; C extending to almost half the distance between R5 and M1; r–m oblique, longer than base of Rs; M1+2 slightly longer than r–m, medial fork complete. M4 entirely absent; A1 very short, scarcely visible. Abdomen. Abdominal tergites and sternites light brownish yellow, with a light distal brownish band on tergites, distal segments darker. S8 U–shape, T8 wide and short. Terminalia ( Figures 25–26 ). Terminalia light brownish yellow. Syngonocoxite covering entire ventral face of terminalia, more sclerotized distal margin with a mesal notch that continuous through a medial longitudinal suture; syngonocoxite covered with setae, but with no spines; no projection of gonocoxite ventrad to insertion of gonostyle. Gonostyle well sclerotized, a digitiform process midway to apex. Aedeagus not strongly sclerotized, projected laterally at apex. No parameres apparent. T9 longer than wide, more or less straight along posterior margin, no distal projections toward ventral margin. Cercus bilobed.

Etymology. This species is named after Prof. Nelson Papavero, who has led dipterology in Brazil since the 1960s and, among other accomplishments, edited the catalogue of the Diptera of the Neotropical region.

Comments. This species is similar in many features to C. aitkeni Lane , as shown by the long syngonocoxite with a shallow notch ventrally and the shape of the strongly sclerotized gonostyle, bearing a digitiform median process. Details of the gonostyle and of the syngonocoxite distally are more than enough to separate them as distinct species.
