Plocoscelus peruanus Hennig, 1935: 49.
Description: Body length 6 mm, wing 4 mm. Palpus dark brown. Clypeus brown and shiny with some pale microsetulae at lateral margin. First flagellomere dark brown with pale microsetulae. Fronto-orbital plates and frontal vitta yellow. Postpronotal lobe dark brown and shiny. Row of katepisternal setae brownish. Fore leg black. Mid and hind femora white in basal third and yellowish apically. Mid and hind tibia brown on basal half, apical half yellowish (Fig. 59). Fore tarsus dark brown with gold/whitish pubescence ventrally at base of tarsomere one. Oviscape dark brown and shiny, apex black. Epandrium brownish.
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. Epicephalon slightly depressed. Inner vertical seta insertion flat, without tubercle. Paracephalon smooth, without swelling (not extending beyond the vertex). Vertex flattened. Line of black supracervical setae weak.
Thorax: Mesonotum white pruinose with sparse pale microsetulae. Posterior notopleural seta insertion slightly protuberant. Scutellum upturned, triangular. Femora with sparse black setulae. Mid and hind tibia flattened, but sulcus on outer face weak. Wing with stigmatal and discal bands, apex clear with a dark and narrow preapical pigmentation. Crossvein r-m clear. 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 sparse yellowish setulae. Female abdomen: Single spermatheca apically broad, ending in a striate cylindrical spermatheca. Paired spermathecal duct delimited by a narrow basal half and a striate broader distal half. Paired spermathecal duct stems thin and smooth in basal third, followed by a large rounded swelling (Fig. 60). Paired spermathecae oval, deeply invaginated until base. Male abdomen: Ejaculatory apodeme reduced and with a narrowed blade, about as wide as sperm pump (Fig. 61). Distiphallus short, about same length as epandrium and ending in a phallic bulb, phallic bulb subequal in length and width.
