DIPTERA FROM NEPAL 103 



in six rows. Anterior dorsocentrals two-thirds as long as posteriors ; distance between anterior 

 and posterior dorsocentrals three-fourths distance between anterior pair. Anterior scutellars 

 long, divergent ; posterior scutellars shorter than anteriors, as long as posterior dorsocentral. 

 Sterno-index about 06. Legs yellow ; fore femur ventrally with about three very long setae ; 

 all metatarsi nearly as long as the other segments together. Preapicals on all legs ; apicals on 

 mid leg. Wings hyaline ; veins yellowish brown ; crossveins clear. Costa reaching slightly 

 beyond i? 4 + 5 . i? 2 +3 only weakly curved to costa apically ; i? 4 + 5 and M nearly parallel. C-index 

 about 27 ; 4V-index about 2-2 ; 4C-index about 11 ; 5x-index about 2-1 ; Ac-index about 

 2-5. Ci-bristles two, subequal ; C3-fringe on basal one-third. Halteres yellowish white. 

 Abdominal tergites pale yellow, each with a broad black entire caudal band. 



Periphallic organs pale yellowish grey. Genital arch narrowly pointed ventrally, setigerous 

 along caudal margin and on ventral tip, caudal margin acutely projected caudally above inser- 

 tion of clasper, with a straight row of about eight long black teeth occupying ventral three-fifths 

 of distal margin. Anal plate oval, large, with short hairs, ventrally broadened and truncate. 

 Decasternum flat, triangular. Phallic organs pale brown. Aedeagus rod-shaped, straight, 

 apically tapering and recurved dorso-anteriorly, two basally inserted elongate distally tapering 

 appendages ; apodeme shorter than aedeagus, apically swollen. PI = 2-5. Anterior para- 

 mere slender, as long as lateral appendages of aedeagus, proximally tapering and attached to 

 the base of aedeagus, apically with a few sensilla. Hypandrial plate large, oval, basally with a 

 stout submedian spine. Ventral fragma Y-shaped, with deep median notch. Posterior para- 

 mere apparently absent, p.f. = aBCdEfg HIklmn. Egg-guide lobe yellowish orange, 

 ventrally dark, elongate fusiform, with about fifteen marginal and four orange-brown discal 

 teeth, distal marginal teeth large. Basal isthmus yellowish brown, medially much swollen, 

 more than one-third as long as lobe. 



Holotype <$. East Nepal : Taplejung District, between Sangu and Tamrang,

Allotype $. Taplejung District, above Sangu, mixed vegetation in dried-up 

 ravine, c. 6,8oo', 16.ii.1962 (R.L.C.), BMNH. 



Paratypes : Taplejung District, 2 d, 2 ?, 1 ex., between Sangu and Tamrang, 

 deep river forge, c. 5,200', x-xi.1961 ; 1 <$, Sangu, mixed vegetation in deep gully, 

 c. 6,200', 2i-13.ii.1962. 1 <J, Arun Valley, east shore of River Arun below Tumling- 

 tar, evergreen shrubs bordering dry stream-beds, c. 1,800', 14-23. xii.1961 (R.L.C.), 

 BMNH, 1 <J, 1 $, from between Sangu and Tamrang deposited at the Tokyo Metro- 

 politan University. 



Closely resembles D. (D) tenuicauda Okada, 1956 (Japan), especially in general 

 structure of <$ and $ genital apparata, and in having anterior reclinate orbital 

 minute, only one strong oral, and a long apical seta of palpus, but distinguished from 

 it by having non-striped mesopleura and apically recurved aedeagus.

 dark brown, with a long apical seta. Ocellar triangle black, convex. Periorbit somewhat 

 glossy grey, convex, relatively broad, medially narrowing, anteriorly almost reaching the
