i2 4 MORPHOLOGY AND TAXONOMY OF ADULT MALES 



Legs long and slender, with the fore pair usually shortest and the hind pair longest ; the ratio 

 length of hind leg to body length is i : 1-54-1-69 (average i-6i). Length of segments (in |x) :

Coxae : with 14-16 (average 15), 22-30 (average 26) and 30-41 (average 37) f.s. and 7-9 

 (average 8), 7-1 1 (average 9) and 12-17 (average 13) h.s. on the fore, middle and hind coxa 

 respectively ; fore coxa with 2-4 (average 3-2) capitate coxal bristles ; apical seta about \ as 

 long as trochanter. Trochanters 23-30 [i wide ; with 6 oval sensilla, 10-17 IS - an d 6-8 h.s., the 

 latter including 2 minute setae near basal ridge, one small seta on outer margin and a long apical 

 seta which, on the fore trochanter, is 1-69-2-31 (average 2 01) times as long as width of 

 trochanter. Femora of medium width (38-46 \l), ratio width to length of hind femur being 

 1 : 4-6-5-3 (average 4-9) ; each with 31-44 f.s. and 12-23 h.s. Tibia 19-25 jx wide, ratio width 

 to length of hind tibia being 1 : 16-18 (average 17) ; each with 92-120 setae, of which 19-33 are 

 h.s. and 71-88 f.s., the latter about i£ times longer than width of tibia ; apical spur about the 

 same size on all tibiae. Tarsi 19-22 y. wide, hind tarsus 6-o-6-6 (average 6-4) times longer than 

 wide ; with 20-32 f.s. and 8-16 h.s. ; tarsal digitules subequal, slightly longer than claw. 

 Claws of medium length, a little longer than width of tarsus ; slightly curved, with small 

 denticle near tip ; ungual digitules subequal, about as long as claw. 



Abdomen 330-460 (average 399) y. long and 300-360 (average 333) \± wide. 



Segments I-VII : tergites represented by a small sclerite on each side on anterior margin of 

 segments II— III, and a weak transverse plate on VI-VII ; sternites represented by a weak 

 transverse plate on segments II, III and VII. Caudal extension of segment VII large, tapering, 

 weakly sclerotized. Dorsal setae : 5-14 (average 9) f.s. on I, 1-5 on II and III, and up to 3 on each 

 of segments IV— VII ; occasionally a single h.s. on I— III, and usually one on each side on each of 

 segments IV-VII. Pleural setae consisting of dorsopleural setae : 2-10 (average 4-4), 1-5 

 (average 2-9), 1-6 (average 3-2), 0-6 (average 3-2), 2-6 (average 4-1) and 1-4 (average 2-2) f.s. 

 on I- VI, and 0-1 (average 03), 1-2 (average i-6), 1-2 (average 1-7), 1-3 (average 2-1) and 0-2 

 (average 1 -6) h.s. on segments II-VI respectively, and of ventropleural setae : up to 5 f.s. on 

 each of segments I II-VI, and usually one (range 0-2) h.s. on IV-VI. Segment VII with 

 12-17 (average 14) f.s. and 3-5 (average 3-4) h.s. ; some of the posterior h.s., usually longer than 

 the rest. Ventral setae : 23-35 (average 29), 14-31 (average 23), 12-22 (average 16), 8-14 

 (average 11), 5-12 (average 9) and 6-11 (average 9) f.s. on segments I I-VII respectively ; 

 usually one h.s. on each side on segments III-VI and 4 on VII. 



Segment VIII : with weak tergite and transverse sternite ; caudal extension forming a 

 prominent, weakly sclerotized, semi-circular lobe, with a large cicatrix posterodorsally, the latter 

 weakly sclerotized and reticulated in the middle ; glandular pouch with 2 long, pointed setae, 

 whose protruding part is 3— 3^ times as long as section within pouch. Small IXth tergite present. 

 Ante-anal setae : 2-5 (average 3-8) f.s., 0-4 (average 1 -6) small h.s. and occasionally one long 

 h.s. Posterior margin with 3-7 (average 4-2) f.s. and 3-4 (average 3-2) h.s. on each side. 



Genital segment. Penial sheath long, about f total body length (ratio 1 : 3-5-3-8, average 

 3-6), 407-445 (average 426) fj. long and 38-44 (average 40) jx wide ; lateral sclerotizations 

 narrowly joined anterior to anus ; length of basal rod about twice that of aedeagus, extending 

 anteriorly from base of the aedeagus for about j| of the distance to apex of the basal membranous 

 area ; apex of sheath with a distinct, finger-like membranous extension. Area from base of 

 sheath to tip of aedeagus with 23-29 (average 25) small sensilla ; a cluster of small sensilla 

 occurring ventrally near apex of sheath. Aedeagus short (87-106, average 95 jx long), penial 

 sheath and basisternum longer, ratios being 1 : 4-1-4-9 (average 4-5) and 1 : 1-53-1-78 (average 

 1 -66) respectively.
