C. flavofasciata sp.n.

( Figs. 13 , 28 )

Diagnosis

Arista distinctly plumose; frons with longitudinal brown band for entire length; two or three frontals; distance between posterior frontal and anterior orbital shorter than distance between anterior and posterior orbital; scutum without transverse band, along transverse suture with distinct yellow­white 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 white, longitudinal brown band for entire length from ocellar triangle to antennal base, equal to width of distance between anterior orbitals. Two or three frontals placed on oblique line, with anterior frontal at least 3 times as far from the inner eye margin than posterior frontal in the case of three frontals; two orbitals. Distance between posterior frontal and anterior orbital is shorter than distance between anterior and posterior orbital. Face white, gena darker brown.

Thorax. Scutum shining black­brown, along transverse suture with distinct yellowwhite fascia; black setulae, without transverse bands of silvery setulae. Postpronotum white. Anepisternum with white to yellow band with lower margin reaching to lower fifth of posterior margin; with pale setulae, lower fifth with black setulae, two anepisternals. Katatergite and anatergite both white. Scutellum white, ventrally with 3 brown apical spots, not visible in dorsal view. Subscutellum black.

Legs brown, tibia and tarsal segments yellow.

Wing. Pattern similar to that of C. pseudotritea (see fig. 9). Hyaline indentation near junction of vein C with apical part of vein R1, reaching to vein R4+5. S­band and inverted Vband not fused. S­band with small subapical tooth. Crossvein DM­Cu straight. R­M ratio 1.14.

Abdomen. Shining black­brown, tergite 2 and 4 along posterior half with yellow band; with black setulae, tergite 2 and 4 along postior band with white setulae and microtrichosity. Spermatheca ovoid in apical part, base slender. Female terminalia, oviscape shorter than abdomen; shining black­brown. Aculeus orange, flattened ( Fig. 13 ), not cylindrical, about 5 times longer than wide; tip blunt, rounded with small teeth ( Fig. 28 ). Body length: 5.44mm; wing length 5.68mm

Etymology

Referring to the distinct yellow­white fasciae on the transverse suture.

Distribution

Cameroon

Comments

This species also belong to the pseudotritea complex with longitudinal band on frons. Only the female is known. It can be distinctly separated by the rounded aculeus tip, unlike any other species of this genus. The main non­sexual difference is the presence of distinct yellow fasciae along the transverse suture.
