Trypeta tritea Walker, 1849: 1034 .

Carpophthoromyia tritea: Austen 1910 , Bezzi 1918, Cogan & Munro 1980.

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.

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) sometimes darker yellow. Two frontals placed on oblique line, with anterior frontal 2 times as far from the inner eye margin than posterior frontal; two orbitals. Face white to yellow, gena and sometimes antennal groove brown; near antennal base darker yellow to brown patches.

Thorax. Scutum shining black­brown, along transverse suture more yellow­brown; black setulae, without transverse bands of silvery setulae. Postpronotum pale brown, slightly paler in ground colour than scutum. Anepisternum with white to yellow band not reaching postpronotum, starting at level with anterior notopleural seta; lower margin to lower third of posterior margin of anepisternum; with pale setulae, ventrally and 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. 12 ). One hyaline indentation in cell c, without darker markings; very deep, reaching cells bm or cu2. S­band and inverted V­band not fused. S­band with very small subapical tooth. Crossvein DM­Cu straight or slightly sinuous. R­M ratio 0.91­0.94.

Abdomen. Shining black­brown, tergite 5 with median yellow spot, posteriorly wider; with black setulae. Spermatheca ovoid in apical part, base slender. Female terminalia, oviscape about as long as abdominal tergites, cylindrical; shining black­brown, with black setulae. Aculeus yellow to orange, slender ( Fig. 15 ), flat, about 20 times longer than wide; aculeus tip straight, pointed, and serrate ( Fig. 33 ).

Body length: 3.87 (3.68­4.00)mm; wing length 4.27 (4.16­4.32)mm

Comments

C. tritea turned out to be a species complex with most species to be differentiated by the shape of the aculeus tip. Three species are currently recognized: C. tritea , C. schoutedeni sp.n. and C. interrupta sp.n..
