Description
Description. Male. Head. Occiput light yellowish brown, setose; mid ocellus absent, lateral ocelli closer from eye margins than diameter of ocellus, ocellar area brown; front and clypeus yellowish, setose; maxillary palpus brown, 1 + 4 palpomeres, increasing in length to apex, setose; labella yellowish, except for the brownish sclerite of basal article. Scape and pedicel rounded, yellowish, setose; flagellomeres yellowish, elongated, basal half brownish, setose. Thorax. Pronotum yellowish, with some longer and other smaller setae. Scutum brown, with four longitudinal yellowish bands intertwined with brownish bands, smaller setae scattered and some stronger acrostical and dorsocentral bristles; scutellum yellowish brown, with brown posterior margin, six stronger scutellar bristles and some smaller setae. Pleural membrane yellowish. Proepisternum light yellowish brown. Anepisternum and katepisternum yellowish brown, mesepimeron yellowish, laterotergite brownish, mediotergite brownish. Anepisternum and katepisternum bare, laterotergite setose, mediotergite with a mesal and a pair of more lateral tufts of setae. Halter yellowish, setose. Legs. Coxae light brown, hind coxae lighter basally, fore and mid femora light brown, hind femur yellowish, with base and apex brownish, tibiae and tarsi yellowish brown, base of hind tibia darker; tibial spurs 1: 2: 2, yellowish, front spur more than twice front tibial width at apex. Wing (Figure 13). Length, 2.6 mm. Maculation pattern similar to C. sapiranga, sp.n. Membrane with macro and microtrichia; humeral cell bare of macrotrichia; basal cell with macrotrichia on distal half. Sc complete, reaching C at basal third of wing; R 1 long, reaching C at distal third of wing; R 5 reaching C before apex of M 1; C extending about a third the distance between R 5 and M 1; r–m oblique, longer than base of Rs; M 1 + 2 longer than r–m; medial fork complete; M 4 entirely absent; A 1 very short, scarcely visible. Abdomen. Abdominal tergites and sternites 1–7 brown. S 8 U–shape, T 8 wide and short. Terminalia (Figure 32). Terminalia yellowish brown. Similar to C. sapiranga, sp.n., but gonostyle smaller, and latero–posterior projections of T 9 smaller, setose, but without spines. Gonocoxite bearing a digitiform projection with a pair of short spines at the apex.
Etymology
Etymology. The name of this species is feminine and refers to those born in the State of Rio de Janeiro.
Discussion
Comments.As commented above, this species seems to fit into a clade with C. fuscipennis, C. plaumanni and C. binocellaris. The shape of the gonostyle, the lack of spines on T 9 and the shape of the parameres allow the differentiation of C. fluminense from the species of the binocellaris – group and from C. sapiranga, sp.n..
