C. schoutedeni sp.n.

( Figs. 11 , 17 , 32 , 37 )

Diagnosis

Arista distinctly plumose; two frontals; scutum without transverse bands; postpronotum white; scutellum with three apical spots, not visible in dorsal view; anterior margin of wing with one indentation in cell c; S­band and inverted V­band separate.

Description

Head. Antennal segments orange. Arista distinctly plumose, longest rays longer than width of first flagellomere. Frons white to yellow. Two frontals placed on oblique line, with anterior frontal 1.5 times as far from the inner eye margin than posterior frontal; two orbitals. Face white to yellow.

Thorax. Scutum shining black­brown, along transverse suture more yellow­brown; pale setulae. Postpronotum white. Anepisternum with white band, lower margin reaching posteroventral corner; with pale setulae, posterior margin in male with few longer black setulae; one anepisternal. Anatergite and katatergite white. Scutellum white, ventrally with 3 brown apical spots, not visible in dorsal view. Subscutellum black.

Legs yellow; fore femur yellow, mid and hind femora brown, basally darker yellow.

Wing ( Fig. 11 ). One hyaline indentation in cell c, with single dark spot; very deep, reaching cells bm or bcu. S­band and inverted V­band not fused. S­band with subapical tooth. Crossvein DM­Cu slightly sinuous. R­M ratio 1.20­1.24.

Abdomen. Shining black­brown, tergites 1­2 largely yellow with brown patches, tergites 3­5 with median yellow spot; with mixed black and pale setulae, tergite 4 along posterior half with silvery microtrichosity. Spermatheca ovoid in apical part, base slender ( Fig. 37 ). Female terminalia, oviscape about as long as abdominal tergites, cylindrical; shining black­brown, with black setulae. Aculeus yellow to orange, flattened ( Fig. 17 ), about 20 times longer than wide; aculeus tip triangular, serrate; below serrated tip with small lateral notches ( Fig. 32 ).

Body length: 4.32 (4.24­4.40)mm; wing length 5.08 (4.96­5.41)mm

Type material

Holotype Ψ: CONGO (D.R.), Basongo, 15­31.VII.1921, H. Schouteden (KMMA). Paratype: 1ɗ, same date and locality as holotype, H. Schouteden (KMMA).

Distribution

Congo (D.R.)

Etymology

Named after Dr H. Schouteden, former director of the Royal Museum for Central Africa in Tervuren, Belgium; and collector of the type material of this newly described species.

Comments

This species belongs to the C. tritea group, comprising also C. tritea and C. interrupta . The main difference is the shape of the aculeus tip with the two subapical constrictions.
