Occiput yellowish orange. Postverticals moderate in size. Anterior reclinate orbital about 

 half as long as others, nearly equally spaced from posterior reclinate and from proclinate, which 

 is inside others. Only one long oral, others much shorter. 



Mesonotum orange-brown, with five narrow dark brown longitudinal stripes, median one faint 

 and ending before posterior extremity, lateral one interrupted at suture, becoming more dorsal 

 behind suture. Scutellum yellowish brown, pollinose. Thoracic pleura paler than mesonotum, 

 with two narrow obscurely dark longitudinal stripes, upper one longer and reaching propleura 

 anteriorly. Two humerals, upper much shorter. Acrostichal hairs in six rows. Anterior 

 dorsocentrals half as long as posteriors ; distance between anterior and posterior dorsocentrals 

 subequal to distance between anterior pair. Anterior scutellars divergent, as long as posteriors, 

 which are slightly nearer to each other than to anteriors. Sterno-index about 0-5 ; anterior 

 sternopleural much thinner ; median one as long as anteriors. Legs yellow ; front and mid 

 metatarsi subequal in length to next three segments together, mid metatarsi slightly longer than 

 next three segments together. Preapicals on all legs ; apicals on fore and mid legs. Fore 

 femur anteroventrally with a row of small black equal-sized spinules on median half. Wings 

 hyaline, costa reaching M ; i? 2 +3 straight ; -ff 4 + 5 and M gently convergent distally. C-index 

 about 3-0 ; 4V-index about 1 5 ; 4C-index about o-8 ; 5x-index about 1 -3 ; Ac-index about 2-7. 

 Ci-bristles two ; 3C-fringe on basal one-fourth. Halteres yellow. Abdominal tergites dark 

 yellowish orange ; iT pale, others each with a broad black, medially narrowly interrupted, 

 posterior transverse band. 



Periphallic organs : Genital arch pale yellowish grey, relatively narrow, swollen and oval 

 ventrally, pubescent and setigerous. Clasper pale brown, triangular, proximally narrowing, 

 narrowly projected upward dorsally to reach the lower tip of anal plate, with a straight row of 

 about eight stout blunt black teeth on entire distal margin. Anal plate large, fusiform, setige- 

 rous and pubescent, ventrally with a tuft of a few short stout black setae directed ventrally. 

 Decasternum pale, broad, triangular. Phallic organs pale yellow. Aedeagus robust, apically 

 blunt, rhombic and basally swollen upward in lateral aspect. Basal apodeme of aedeagus 

 straight, half as long as aedeagus. Anterior parameres oval, small, close to each other, finely 

 pubescent, basally attached to aedeagus, subapically with about two sensilla. Hypandrial plate 

 quadrate, finely pubescent, medially with a long submedian spine. Ventral fragma elongate, 

 quadrate ; lateral corners sharply pointed apically. PI = 20. p.f. = aBCdefg HIklmn. 



Holotype $. East Nepal : Taplejung District, Sangu, mixed vegetation by 

 stream in gully, c. 6,200', xi. 1961-1.1962 (R.L.C.), BMNH. 



Allied to notostriata in having striped front and mesonotum as well as thoracic 

 pleura, but differing from it in having an odd number of mesonotal stripes, larger 

 fork of arista, rounded wing tip, equal-sized short spinules on fore femur, non- 

 pubescent aedeagus, and in the details of $ genital armatures.
