C. interrupta sp.n.

( Figs. 10 , 16 , 31 , 38 )

Diagnosis

Arista distinctly plumose; two frontals; scutum without transverse bands; postpronotum brownish; 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, the latter divided in two parts.

Description

Head. Antennal segments brown. Arista distinctly plumose, longest rays longer than width of first flagellomere. Frons yellow; upper third (area in between orbitals to upper margin ocellar triangle) slightly darker yellow. Two frontals placed on slight oblique line, with anterior frontal 1.5 times as far from the inner eye margin than posterior frontal; two orbitals. Face white to yellow, gena brown; area near antennal base brown.

Thorax. Scutum shining black­brown, along transverse suture more pale brown; black setulae, without transverse bands of silvery setulae. Postpronotum brown, same ground colour as scutum. Anepisternum with white to yellow band not reaching postpronotum, starting at level with anterior notopleural seta; lower margin reaching lower fourth of posterior margin or almost reaching posteroventral corner of anepisternum; with pale setulae, posteriorly with black setulae; one anepisternal. Anatergite and katatergite brown. Scutellum white, ventrally with 3 brown apical spots, not visible in dorsal view. Subscutellum black.

Legs brown, tarsal segments and fore tibia yellow; mid and hind tibia brown basally, gradually paler colour with only apical third completely yellow.

Wing ( Fig. 10 ). One hyaline indentation in cell c, without darker markings; very deep, reaching cells bm or cu2. S­band and inverted V­band not fused. S­band with distinct subapical tooth. Legs of inverted V­band not touching in cell r4+5, divided in two parts (subapical band and posterior apical band). Crossvein DM­Cu slightly sinuous. R­M ratio 1.00­ 1.15.

Abdomen. Shining black­brown, tergite 5 with median yellow spot; with black setulae. Spermatheca ovoid apical but based thickened ( Fig. 38 ). Female terminalia, oviscape about as long as abdominal tergites, cylindrical; shining black­brown, with black setulae. Aculeus yellow to orange, flat ( Fig. 16 ), about 10 times longer than wide; aculeus tip triangular, serrate ( Fig. 31 ).

Body length: 4.64 (4.20­5.02)mm; wing length 4.80 (4.62­4.72)mm

Etymology

Referring to the interrupted inverted V­band in the wing.

Type material

Holotype Ψ: CONGO (D.R.), Yangambi, VI.1960, J. Decelle (KMMA). Paratypes: GHANA, 1Ψ, Aburi, 23.III.1911, L. Armstrong, “on leaf of Tabernaemontana” (BMNH). KENYA, 1ɗ 1Ψ, Meru, 5­7000 ft, 24­29.XII.1970, A.E. Stubbs (BMNH).

Distribution

Congo (D.R.), Ghana, Kenya.

Comments

C. interrupta is closely related to C. tritea but can be differentiated by the inverted Vband being interrupted. A character not found in other Carpophthoromyia although the bridge is often weak in some other species as well. The female aculeus tip is serrated, as seen in other species of the tritea group but is broader than in the other species.
