Dacimita David & Hancock , gen. n.

Type species Dacimita curvifasciatus David & Hancock , sp. n.

Diagnosis: Head ( Fig. 2 ) higher than long with single pair of weak frontal setae; ocellar and orbital setae vestigial/ absent. Face concave, fulvous with elongate, black markings; first flagellomere shorter than face, arista shortplumose; postocciput and vertex swollen. Scutum ( Fig. 3 ) elongate, black, microtrichose, with yellow lateral presutural and sublateral postsutural vittae; anepisternal stripe ( Fig. 4 ) broad, reaching postpronotal lobe; chaetotaxy reduced. Wing ( Fig. 7 ) elongate, predominantly hyaline with two transverse bands, cell bm as broad as cell cua, extension of cell cua shorter than main part of cell cua; crossvein r-m placed near midlength of cell dm. Abdomen ( Figs. 5, 6 ) elongate, slightly petiolate, with black transverse bands on tergites 2−5. Epandrium ( Figs. 8, 9 ) sclerotised, with well developed setae, proctiger larger than epandrium; epandrium and surstylus not demarcated; phallus with well developed acrophallus, subapical lobe and preglans lobe present. Oviscape ( Fig. 11 ) broad, setose; eversible membrane broad with semicircular spicules ( Fig. 12 ), taeniae not prominent; aculeus ( Figs. 11, 12 ) as broad as eversible membrane with conical apex and preapical constriction, sternite 8 with prominent lobes.
