DIPTERA FROM NEPAL 95 



3-4 ; 4C-inclex about 1-4 ; 5x-index about 37 ; Ac-index about 2-2. Ci-bristles two, sub- 

 equal ; C3-fringe on basal two-sevenths. Halteres yellow. Tergites yellowish brown, with broad 

 black cross-band towards tip of abdomen. 



Periphallic organs : Genital arch broad, black, pale grey at lower one third, caudal margin 

 setigerous and gently convex below middle. Clasper in two sets : primary clasper ventrally 

 narrowing, triangular, grey, with about ten small black teeth in a straight row on lower two- 

 thirds of distal margin ; secondary clasper quadrate, above the primary one, partly attached to 

 the lower tip of anal plate, with two large and one small black ventrally curved stout bristles on 

 distal margin and a strong spine on inner margin, lower margin hairy. Anal plate separated 

 from genital arch, oval, setigerous, with about three strong black bristles below. Phallic 

 organs : Aedeagus compact, hairy, distally somewhat narrowing, subbasally with paired lateral 

 black acute projections ; basal apodeme slightly shorter than aedeagus, straight, pale yellowish 

 orange. PI = 1-4. Anterior paramere conical, black, rounded and with a few sensilla apically, 

 with two acute projections medially, basally prolonged to join the base of aedeagus. Posterior 

 paramere elongate, pale orange, gently curved outward, apically tapering. Ventral fragma 

 quadrate, pale, with a large broad caudomedian process, which is apically shallowly concave and 

 subapically with a pair of short submedian spines, p.f. = aBcDefGHIKlMN. Egg-guide lobe 

 yellowish brown, oblong, gently narrowing apically and broadly truncate, with about fourteen 

 black pointed marginal teeth, last tooth well removed from penultimate. Subterminal hair 

 distinct. Basal isthmus black, one fourth as long as lobe.

 Metropolitan University. 



Resembles D. (S.) auraria Peng, 1937 (China and adjacent countries) in having 

 trapezoid front and laterally clawed aedeagus, but differs in having <$ face not 

 whitish, periorbit black (grey in auraria), aedeagus hairy (bare in a.), anterior par- 

 mere conical and hairy (elongate and not hairy in a.), and caudal margin of genital 

 arch without prominent conical projection.
