Rosapha flavistigmatica  sp. nov.

( Figs 19 –21View FIGURES 12 – 21, 35View FIGURES 33 – 46, 62View FIGURES 55 – 62, 79View FIGURE 79)

Diagnosis. Basal part of flagellum subconical, apical style flattened, with short apical seta, frontal tomentose spots present. Scutum black, scutellum black with yellow margin and spines. Wing almost hyaline with yellow stigma, legs completely yellow, abdomen black.

Description. Male ( Figs 19 –21View FIGURES 12 – 21, 35View FIGURES 33 – 46, 62View FIGURES 55 – 62). Length: body 5.6 mm, wing 4.8 mm. Head slightly longer than high in profile, transversely broadened in dorsal view, about 1.5 times as broad as long, ocellar triangle prominent, vertex shorter than distance between anterior and posterior ocelli. Upper frons relatively short, at most as broad as anterior ocellus, lower frons subtriangular, with whitish tomentose and finely medianly divided spot ( Fig. 35View FIGURES 33 – 46). Antennal stylus only slightly longer than rest of antenna, flattened, band-shaped, with short apical seta. Whitish tomentose facial stripes along eye margins not touching frontal spot. Palpi brown, labellum brownish but blackish in distal half.

Thorax black, only postpronotal calli, narrow upper margin of anepisternum and broad margin of scutellum including spines yellow ( Fig. 62View FIGURES 55 – 62). Outer scutellar spines only slightly shorter than inner ones. Stigma yellow, cell r 5 very slightly infuscated. Halter yellow. Legs completely yellow, only last two tarsomeres of hind legs more brownish.

Abdomen elongate, slightly widened and clavate distally, entirely black, only terminalia yellow. Male terminalia ( Figs 19–21View FIGURES 12 – 21): Proctiger pentagonal, cercus oval ( Fig. 19View FIGURES 12 – 21), genital capsule ( Fig. 20View FIGURES 12 – 21) with fairly low and apically rounded medial process posteriorly, each gonocoxite with fairly long inner posterior lobe, gonostylus flattened with broad submedial spine, aedeagal complex ( Fig. 20View FIGURES 12 – 21) long and slender, aedeagal apodeme abruptly dilated proximally.

Female unknown.

Etymology. The name indicates the yellow (= flavus) stigma on the wing.

Remarks. Very similar to R. obscurata  but the vertex is short as in other species of this genus, the frontal spot is separated from facial stripes and the upper margin of the anepisternum is broadly yellow.
