Plocoscelus harenosus Cresson, 1930: 333 View in CoL .

Description: Body length 7 mm, wing 4 mm. Head and abdomen brown, somewhat ferruginous. Mesonotum darkened. Palpus mostly dark brown, outer face white. Clypeus brown with pale microsetulae. First flagellomere black covered with pale setulae. Fronto-orbital plates brown sometimes with a black spot posteriorly. Postpronotal lobe and scutellum brown. Row of katepisternal setae brownish. Mid and hind femora brown. Fore tarsus dark brown with gold/whitish pubescence ventrally at base of tarsomere one. Oviscape shiny dark brown, apex black. 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. Paracephalon smooth, without swelling (not extending beyond the vertex). Vertex rounded. Line of black supracervical setae strong.

Thorax: Mesonotum golden pruinose irregularly darkened. Scutellum upturned, triangular. Femora with sparse black setulae. Mid and hind tibia flattened, but sulcus on outer face weak. Wing apex clear with three preapical black 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 pale microsetulae. Single spermathecal duct apically broad and tapered basally. Single spermatheca cylindrical, peanut-like. Paired spermathecal duct delimited by a narrow basal half and a broad distal half. Paired spermathecal duct stems thin and smooth in basal third, followed by a small rounded swelling ( Fig. 44 View FIGURES 43–45 ) and a striate duct that leads the spermathecae. Paired spermathecae sac-like (distally swollen and tapered basally), striate and invaginated from apical half. Male abdomen: Ejaculatory apodeme reduced, blade small and short, sperm pump wider than blade. Hypandrium short, length equal to or shorter than epandrium. Distiphallus long, longer than epandrium, ending in a phallic bulb, subequal in length and width ( Fig. 45 View FIGURES 43–45 ).

Distribution: Colombia, Costa Rica, Ecuador, Guiana, Mexico, Panama.

Comments: Cardiacephala harenosa is similar to C. schildi , but differs in having three preapical black spots on the wing (sometimes thicker but not forming an aligned preapical darkened stripe) and completely different female genitalia. This species also has some similarity to C. modesta , although the inner vertical seta of C. harenosa does not arise from a tubercle and males have a conspicuously short and small ejaculatory apodeme.
