Description: Body length 9 mm, wing 5 mm. Palpus dark brown. Clypeus dark brown, shiny. First flagellomere dark brown, covered with pale microsetulae. Fronto-orbital plates and frontal vitta dark brown. Paracephalon and epicephalon brown, shiny. Frontal vitta with a dark brown stripe extending to vertex. Row of katepisternal setae brownish, some of them shiny gold. Fore leg dark brown. Mid and hind femora brown, yellowish at apical third. Fore tarsus dark brown with gold/whitish pubescence ventrally at base of tarsomere one. Oviscape dark brown, apex yellow. Epandrium brown.

Head: Palpus broadened basally and gradually tapering to apex. Clypeus short, length less than half of width. Two frontal setae. Inner vertical seta insertion flat, without tubercle. Paracephalon swollen and conical, extending beyond the vertex and without clearly divisions with epicephalon. Vertex flattened. Black supracervical setae sparse, weak.

Thorax: Mesonotum whitish pruinose with sparse pale setulae. Scutellum upturned, triangular. Femora with sparse black setulae. Mid and hind tibia flattened, but sulcus on outer face weak. Wing stigmatal and discal band delimited, apical band darkened with three preapical hyaline rounded spots. Crossvein r-m with small dark spot. R4+5 and M1+2 meeting at the wing margin. A1+CuA2 as long as CuA2. Female cervical sclerite smooth, without swelling.

Abdomen: Tergites with brownish setulae. Female abdomen: Oviscape with sparse pale microsetulae. Single spermathecal duct uniformly thick, ending in a peanut-like cylindrical spermatheca. Paired spermathecal duct divided into a narrow basal half and a broader distal half. Paired spermathecal duct stems thin and smooth on basal third, followed by a small rounded swelling and a small appendix ( Fig. 41 View Figure ). Paired spermathecae striate and saclike (distally swollen and tapered basally), deeply invaginated from apex to base. Male abdomen: Ejaculatory apodeme about same length as epandrium and with a broad blade, wider than sperm pump ( Fig. 42 View Figure ). Phallapodeme extending to anterior limit of hypandrium. Distiphallus short, about same length as epandrium. Distiphallus ending in a phallic bulb, phallic bulb subequal in length and width.

Distribution: Brazil, Colombia, French Guiana, Guiana, Surinam, Panama, Trinidad, Venezuela.

Comments: The holotype abdomen was missing when Steyskal (1967) examined it. C. guttata  has a swollen paracephalon with no clear division from the epicephalon, and has a dark apical wing band with three preapical hyaline rounded spots. Illustrations of head, wing and genitalia of this species can also be found in Albuquerque (1989: 21, Figs. 2–8View FIGURES 2–4View FIGURES 5–8).
