Description
Description. Male. Head. Head brownish yellow, darker at vertex; mid ocellus absent, lateral ocelli closer to eye margins than ocellus diameter, ocellar area brown; front and clypeus yellowish, pubescent. Maxillary palpus brownish, palpomeres 1 + 4, increasing in length to apex; labella yellowish, sclerite of basal article brownish. Scape and pedicel rounded, whitish yellow, pubescent; flagellomeres whitish yellow, except for basal fourth, pubescent. Thorax. Pronotum yellowish, with some longer and other smaller setae. Scutum light brown, four longitudinal yellowish bands, intertwined by light brownish bands, smaller setae scattered and some stronger acrostical and dorsocentral bristles; scutellum light brownish, darker at posterior border, six stronger scutellar bristles and some smaller setae. Pleural sclerites light brownish, anepisternum, laterotergite and mediotergite brown. Anepisternum setose, katepisternum bare, laterotergite setose, mediotergite with a median and a pair of more lateral tufts of setae, lighter close to base of abdomen. Halter yellowish, pubescent. Legs. Legs mostly yellowish, brownish on coxae and femora basally; tibial spurs 1: 2: 2, light brown, spur length more than twice apex of tibiae. Wing (Figure 6). Length, 2.8 mm. A more or less continuous brownish maculae around base of Rs, r–m, M 1 + 2 and base of medial fork, and other maculae at apex of anal lobe, at distal eighth of wing (beyond the apex of R 5), and a distinctive transverse band at level of apex of R 1. Membrane with macro and microtrichia; humeral cell bare of macrotrichia; basal cell short, with scarce macrotrichia on membrane, only on distal half. Sc complete, short, reaching C at basal fourth of wing, much before origin of Rs; R 1 long, reaching C at distal third of wing; R 5 reaching C before apex of M 1; C extending two fifth the distance between R 5 and M 1; r–m oblique, slightly 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. Abdominais tergites 1–7 yellowish brown. S 8 U–shape, T 8 wide and short. Terminalia (Figures 21–22). Terminalia elongated, yellowish brown. Syngonocoxite covering the entire ventral face of the terminalia, bearing a mesal suture across the entire plate, a pair of short spines at the distal margin on a small projection at each side, no projection of the gonocoxite ventrad to the insertion of the gonostyle. Gonostyle well sclerotized, triangular, slender to the apex, with no setae. Aedeagus with a pair of elongated anterior arms, distally with a short projection on the outer margin. T 9 rectangular, elongated, with no mesal notch at distal margin. Cercus simple, elongated, with fine setae at apex.
Etymology
Etymology. The name of this species is feminine and, because of its similarity to C. vicina Matile (which means neighbour), the Greek name accola (having the same meaning) is used in apposition.
Discussion
Comments. The male terminalia of this species is very similar to that of the lanei – group, especially C. vicina Matile and C. variegata Matile, which have a shallow distal notch mesally on the syngonocoxite, with a single spine at the distal margin on each side. The shape of the gonostyle is sufficiently different from C. vicina to justify a separate species rank. Two males in poor condition from Caruaru, State of Pernambuco, belong to this species, but we decided to not to give them paratype status.
