134 MORPHOLOGY AND TAXONOMY OF ADULT MALES 



Wings : 840-1092 (980)11 long and 392-476 (434)11 wide ; with 3 alar setae and 2 circular 

 sensoria. Hamulohalterae 76-85 (79) |i long and 15-21 (i8)(x wide ; with one, 55-61 (58)11 

 long apically hooked seta, i.e. the ratio length of seta to the length of the hamulohaltera about 

 1 : 14. 



Legs : Moderately long ; the ratio length of the hind leg to the total length of the body 

 1 : 1-6-1-8 (1-7). Coxa and trochanter about 52 and 27(1. wide respectively. Femur about 43(1 

 wide ; that of fore leg shortest and that of hind leg longest ; the ratio width to length of the 

 hind femur being about 1 : 5-4. Tibia about 24^ wide ; with 2 apical stout spurs and 3-5 

 smaller ones ; the ratio lengths of femur to tibia in fore leg 1 : 1-1-1-2 (1-16). Tarsus about 

 21 (x wide ; tarsal digitules apically knobbed, about 34^ long. Claw uniformly tapering to a 

 pointed tip ; ungual digitules finely pointed. In the following table, the lengths of the leg 

 segments (in microns) and the number of setae on each are given :

Abdomen : 403-578 (486) (i long and 251-327 (296) jx wide. Tergites of segments I and II 

 small ; those of segments VIII and IX + X large and distinct. Sternites of segment VIII 

 ill-defined. Ostioles weakly developed. Abdominal setae on each side : Dorsal setae : Fleshy 

 setae 0-1 on segment I, 2-3 on segment II, 1-3 on segment III, and 1-2 on segments IV to 

 VIII ; hair-like setae 2-4 on segment I, 3-4 on segments II to V, 2-4 on segments VI and VII, 

 and 1-2 on segment VIII. Pleural setae 2-4 h.s. on segment I, 4-5 on segments II to VII, 

 and 3-4 on segment VIII, including one slightly longer seta. Ventral setae : Fleshy setae 

 0-1 on segments II, III and IV ; hair-like setae usually 2-3 on segments II to VII, and 

 occasionally 1 or 4 ; ventral setae absent on segment VIII. Abdominal disc pores : Segments 

 I-VII with 6-11 (8-6), 1-2 (i-6), 1-2 (1-5), 1-2 (1-5), 1-3 (1-9). 2-4 (2-5), and 3-5 (4-3) pleural 

 pores, respectively. 



Glandular pouches well developed ; setae of glandular pouch include two, 360-412 (387)11 

 long tail setae and one, 58-92 (76) [i long seta, the ratio length of the tail setae to the total length 

 of the body being 1 : 3-0-3-8 (3-4). 



Genital segment : Subtriangular in dorsal view, with the style comparatively broad and 

 apically rounded ; the latter curving upwards in lateral view. Penial sheath 153-168 (162) ji 

 long and 76-89 (85)11 wide, i.e. the ratio its length to its width 1-8-2-0 (1-9) : 1, and its length 

 to the total length of the body 1 : 7-2-8-9 (8-2). Basal ridge of penial sheath with a small 

 projection ; process of penial sheath absent. Aedeagus tapering to a pointed tip. Setae of
