Diagnosis

Arista distinctly plumose; two frontals (sometimes third poorly developed); scutum with one transverse band; usually transverse suture with yellow fascia; postpronotum white; scutellum with three apical brown spots, only visible in ventral view; anterior margin of wing with one indentation near junction of vein C with apical part of vein R1; Sband and inverted V­band separate.

Description

Head. Antennal segments orange. Arista distinctly plumose, longest rays longer than width of first flagellomere. Frons yellow. Two frontals, sometimes third, poorly developed, anterior one; placed on oblique line with anterior frontal 3 times as far from the inner eye margin than posterior frontal; two orbitals. Face white to yellow, sometimes gena darker yellow.

Thorax. Scutum shining black­brown, along transverse suture sometimes more yellow; black setulae, except for one broad transverse band with silvery setulae anteriorly of transverse suture; sometimes silvery setulae extended anteriorly along centre of presutural area; transverse suture with yellow fascia. Postpronotum white. Anepisternum largely white to yellow, only lower fourth dark yellow to yellow­brown; with pale setulae, ventral fourth posteriorly with black setulae; two anepisternals. Anatergite and katatergite white. Scutellum white, ventrally with 3 brown apical spots, not visible in dorsal view. Subscutellum black.

Legs yellow; in female femora red­brown.

Wing. ( Fig. 6 ). Basal part with streaks and patches (especially near base of cell dm). One hyaline indentation near junction of vein C with apical part of vein R1; reaching halfway R4+5 and M. S­band and inverted V­band not fused. S­band with subapical tooth, sometimes small. Inverted V­band partly separated anteriorly in male. Crossvein DM­Cu straight. R­M ratio 1.30­1.39.

Abdomen. Shining black­brown, with black setulae. Tergite 2 posteriorly more orange, tergite 4 with median yellow spot posteriorly and with white setulae and microtrichosity on spot. Spermatheca ovoid in apical part, base slender. Female terminalia, oviscape about as long as abdominal tergites; shining black­brown, with black setulae. Aculeus yellow to orange, flattened; about 8 times longer than wide ( Fig. 19 ), aculeus tip simply pointed ( Fig. 25 ), straight.

Body length: 4.86 (4.32­5.44)mm; wing length 5.04 (4.72­5.68)mm

Comments

Sexual dimorphism is rare among the Carpophthoromyia species. In some cases, such as in C. tessmanni , C. litterata and C. scutellata , there is a difference in colouration of the legs with the female having darker femora. The original type series consisted of 5 males and 3 females from Uelleburg (of which 2 males and 2 females are in MNHU and 1 male in BMNH) and one female from Nkolentangan. The whereabouts of the latter and 2 males and 1 female from Uelleburg are unknown.
