Diagnosis

Body length about 5 mm. General colour yellowish. Wing with both crossveins brownish shadowed, costal border slightly darkened, darker towards wing tip, also tip of r 1 slightly darkened. Frons with about 150 interfrontal setulae. Frontal index about 1.10–1–20. Arista with 7–11 long dorsal, 6–9 long ventral and about 6–8 short inner branches, plus short terminal fork.Epandrium sparsely setose and only at distal 1/3 (proximal 2/3 devoid of setae). Surstylus with a conspicuously sinuate row of ca. 25 evenly spaced, quite long, and roundish-tipped prensisetae. Aedeagus dorsoventrally flattened, somewhat ringed, toilet seat-shaped, distally bearing one dorsal, folded over itself, pentagon-shaped sclerite. Outer paraphysis dorsoventrally flattened, proximally not bifid (as in R.obesa , but bifid or even trifid in R.gigantea , Fig.71), slightly shorter than aedeagus, distally widened and bearing four setulae (slightly widened distally and devoid of setulae in R. gigantea , not widened distally but devoid of setulae in R.obesa ). Aedeagal apodeme distally deeply (or not so) bifid with sharply pointed (or somewhat squared) tips not remarkably turned inwards; ventral rod tilde-shaped in lateral view, mostly membranous.
