C. debeckeri sp. n.

( Fig. 1 )

Diagnosis

Arista short pubescent; two frontals; scutum with two broad transverse bands; postpronotum white; scutellum white with three brown merged spots along apical half; anterior margin of wing with hyaline indentations in cell c and sc; S­band and inverted V­band separate.

Description

Head. Antennal segments yellow to orange. Arista short pubescent, longest rays less than half width of first flagellomere. Frons white to yellow, upper part darker. Two frontals placed on almost straight line, with anterior frontal at most 1.5 times as far from the inner eye margin than posterior frontal; two orbitals. Face white.

Thorax. Scutum shining orange­brown; black setulae, except for two broad transverse bands with silvery setulae; one anteriorly of transverse suture, continuing posteriorly along lateral margins to base of postsutural supraalars or almost so, second one near dorsocentrals. Postpronotum white. Anepisternum with white band with lower margin reaching posteroventral corner or almost so; with pale setulae, two anepisternals. Anatergite and katatergite white. Scutellum white, apical half with three brown spots, largely merged with area in between spots yellow­brown. Subscutellum orange­brown.

Legs yellow to yellow­orange.

Wing ( Fig. 1 ). Hyaline indentation in cell c, with few black patches and streaks; also basal part of cells dm and cu2 partly hyaline. Hyaline indentation near junction of vein C with apical part of vein R1 reaching R4+5. S­band and inverted V­band completely separate. S­band without subapical tooth. Crossvein DM­Cu straight. R­M ratio 1.18–1.37.

Abdomen. Shining orange­brown, posterior margin to half of tergites 2–4 more white to yellow, tergite 5 orange; with black setulae, tergites 2–4 with silvery setulae and microtrichosity along white to yellow band. Spermatheca cylindrical. Female terminalia, oviscape about as long as abdominal tergites; shining orange, with black setulae. Aculeus orange, cylindrical, about 15 times longer than wide; aculeus tip slightly downcurved.

Body length: 6.4 (6.0–6.8) mm; wing length 7.36 (7.04–7.68) mm.

Material examined

Holotype Ψ: MALAWI, Chitipa district, Jembya Reserve, 18km SSE Chisenga, 10°08’S 33°27’E, 1,870m, 11–20.I.1989, J. Rawlins & S. Thompson (CMNH). Paratypes: 2ɗ 1Ψ, same locality and data as holotype. All type material is deposited in the CMNH except for two paratypes in the KMMA.

Etymology

Named in honour of Mr J. Debecker, recently retired technician at the Royal Museum for Central Africa, and for many years in charge of the Diptera collection at this institution.

Distribution Malawi.

Comments

This new species is similar to other representatives with two transverse bands on the scutum, hyaline markings both in cell c and near junction of vein C with apical part of vein R1, and a stout rounded aculeus. It resembles C. procera and C. scutellata except for the presence of distinct apical spots on the scutellum. From C. litterata it can be differentiated by the wing banding. It differs from all the above species by the presence of only two frontals.
