 much broadened, two-thirds as long as front. Postverticals absent. Front brownish black, 

 glossy, somewhat purplish, quadrate, as broad as long. Clypeus black or dark brown. Face 

 yellowish brown, highly convex below. Carina yellowish orange or dark brown, high, short, less 

 than half as long as face. Cheeks dark brown, paler above, about two-ninths as broad as the 

 greatest diameter of eye, narrow below. Two long orbitals, no posterior reclinate ; proclinate 

 orbital slightly shorter than reclinate ; both orbitals equidistant from eye margin. Vibrissae 

 thin, long ; succeeding orals short. 



Mesonotum convex, yellowish or dark reddish brown, glossy, posteriorly darker. Scutellum 

 triangular, tip protruded dorsoposteriorly, black, marginally white. Thoracic pleura pale 

 yellowish grey, with a black longitudinal stripe above. One humeral. Acrostichal hairs in six 

 rows. Posterior dorsocentrals slightly longer than anteriors ; distance between anterior and 

 posterior dorsocentrals four-sevenths distance between anterior pair. Anterior scutellars 

 parallel, half as long as posteriors, which are twice as distant from anteriors as from each other. 

 Only one stenopleural. Legs pale yellowish grey ; fore femur basally black ; fore and mid 

 coxae black ; hind coxa white ; mid and hind femora subapically black. Fore femur with 

 anteroventrally a row of about ten small black teeth. Front metatarsi somewhat shorter than 

 next three segments together, mid and hind metatarsi as long as the rest of segments together. 

 Preapicals on all legs ; apicals prominent on mid leg. Wings broad, with scattered large black 

 patches roughly in six transverse rows. Costa irregularly sinuous, alternatively white and black. 

 i? 2+3 gently curved to costa apically ; R t + b and M slightly divergent distally ; posterior cross- 

 vein curved outward. C-index about 1-3 ; 4"V r -index about 40 ; 4C-index about 4-1 ; 5X- 

 index about 1-3 ; Ac-index about 38. Ci-bristles one, small ; C3-fringe on basal two-thirds. 

 Halteres black. Abdomen narrowing anteriorly ; abdominal tergites mostly glossy black,

Taplejung District, Sangu, rotting fruits of Bhor tree on ground, c. 6,200', 

 7-31.X.1961, 1 $ ; below Sangu, by stream in shady ravine, c. 6,000', 30.x. 1961, 1 $ 

 (R.L.C.). 



This species has some features characteristic of the genus Liodrosophila Duda : 

 an anteroventral row of small bristles on fore femur, smooth glossy front, and narrow 

 triangular egg-guide. It has, however, no postverticals, no anterior reclinate 

 orbital, and only one sternopleural, characteristics of the genus Hypselothyrea. 



Distribution : Nepal (new locality), Sumatra, Formosa.
