( Figs. 66–69 View Figure )

Description: Body length 8 mm, wing 5 mm. Palpus mostly dark brown, white on outer face. Clypeus brown, shiny. First flagellomere dark brown covered with pale microsetulae. Fronto-orbital plates dark brown. Frontal vitta brown, opaque. Postpronotal lobe yellow, shiny. Row of katepisternal setae brownish. Mid and hind femora brown, slightly yellowish apically. Hind femur narrowly white basally. Fore tarsus dark brown with gold/whitish pubescence ventrally at base of tarsomere one. Oviscape yellow and shiny, apex dark brown. Epandrium yellow.

Head: Palpus broadened basally and gradually tapering to apex. Clypeus short, length less than half of width. Two frontal setae. Frontal vitta with a narrowed depression centrally, reaching ocellar triangle. Inner vertical seta insertion flat, without tubercle. Epicephalon slightly depressed. Paracephalon smooth, without swelling (not extending beyond the vertex). Vertex flattened. Black supracervical setae sparse, weak.

Thorax: Mesonotum golden pruinose with sparse yellowish microsetulae. Scutellum upturned, triangular. Femora with sparse black setulae. Mid and hind tibia flattened, sulcus on outer face weak but somewhat curved (not extremely dilated as in C. nigra  ). Wing with stigmatal and discal bands, apex clear with a dark and narrow preapical pigmentation. Crossvein r-m with small dark spot. R4+5 and M1+2 ending separately in wing margin. A1+CuA2 as long as CuA2. Female cervical sclerite smooth, without swelling.

Abdomen: Tergites with brownish setulae. Female abdomen: Single spermathecal duct uniformly thick, spermatheca cylindrical. Paired spermathecal duct divided into a narrow basal half and a broader distal half. Paired spermathecal duct stems thin and smooth in basal third, followed by a small rounded swelling and a broad, striate apical third ( Fig. 67 View Figure ). Paired spermathecae cylindrical, striate and deeply invaginated. Male abdomen: Ejaculatory apodeme somewhat thin, bigger than epandrium and with a broad blade, wider than sperm pump ( Fig. 69 View Figure ). Phallapodeme extending to anterior limit of hypandrium. Distiphallus long, longer than epandrium, ending in a cylindrical phallic bulb about three times as long as wide.

Distribution: Brazil, Colombia, Ecuador, French Guiana, Peru.

Etymology: The name C. planivertex  refers to the conspicuously flattened part of the head posterior to the ocellar triangle, especially the vertex.

Comments: C. planivertex  is similar to C. aeruginosa  , from which it can be distinguished by its striking yellow/brownish coloration. Also, while males present a very unusual phallic bulb (slightly elongated and unusually cylindrical), females have conspicuously cylindrical and thin paired spermathecae, differing from all other Cardiacephala  .
