Description
Description. Male. Head. Occiput yellowish, darker at the vertex; three ocelli present, aligned, median ocellus less than half the size of other two, lateral ocellus separated from eye margin by a distance larger than ocellus diameter; front and clypeus yellowish, setose; maxillary palpus yellowish, setose, palpomeres light brown, 1 + 4 palpomeres, increasing in length to apex; labella yellowish. Scape and pedicel rounded, yellowish, setose; flagellomeres whitish at base, brownish on distal two thirds, setose. Thorax. Pronotum light yellowish, with some longer and other smaller setae. Scutum homogeneously yellowish, smaller setae scattered and some stronger acrostical and dorsocentral bristles; scutellum yellowish, slightly darker at posterior margin, four stronger scutellar bristles. Pleural membrane yellowish. Proepisternum light yellowish brown. Pleural sclerites yellowish. Anepisternum setose, katepisternum bare, laterotergite setose, and mediotergite with a mesal and a pair of more lateral tufts of setae. Halter yellowish, setose. Legs. Legs homogeneously yellowish; tibial spurs 1: 2: 2, yellowish, front spur more than twice front tibial width at apex. Wing (Figure 8). Length, 2.3–2.7 mm. Wing nearly devoid of brownish maculae, just slightly darker to apex. Membrane with macrotrichia, but bare of microtrichae; humeral cell with macrotrichia on its entire length; basal cell with macrotrichia covering its entire length; Sc complete, short, reaching C at basal fourth of wing; R 1 short, reaching C just beyond mid of wing; R 5 relatively short, reaching C before apex of M 1; C extending nearly half the distance between R 5 and M 1; Rs very short; r–m oblique, longer than M 1 + 2; M 1 + 2 short; medial fork complete; M 4 entirely absent; A 1 very short, scarcely visible. Abdomen. Abdominal tergites and sternites 1–7 yellowish. S 8 U–shape, T 8 wide and short. Terminalia (Figures 23–24). Terminalia yellowish. Syngonocoxite extending to distal margin of terminalia, simple, bearing setae, but no spines. Gonostyles well sclerotized, short and curved, with a comb of spines at apex, directed to each other. Parameres weakly sclerotized, elongate and slender, curved over itself. Aedeagus well sclerotized, with a distal beak–like projection ventrally directed. Cercus simple, with few many normal setae and four distinctive curved spines.
Etymology
Etymology. The name of this species is feminine and refers to the wing membrane without the usual brownish maculae.
Discussion
Comments. While describing C. flabellifera, Matile (1996) refers to the sclerotized structure of the male terminalia as the “peignes apicaux du synsclérite”, i.e., an apical comb that would be a projection of the syngonocoxite. The examination of the specimens of C. claripennis, sp.n. indicates that this sclerite is most certainly the gonostyle, not articulated to the distal margin of the syngonocoxite. The problem with the homology of this sclerite, however, does not raise any doubt about the very close relationship between these two species, as indicated by the shape of the gonostyle and of the cercus.
