52 MORPHOLOGY AND TAXONOMY OF ADULT MALES 



F.s. slender and sometimes difficult to separate from h.s. 



Coxae each with 4-9 f.s. and 10-19 h.s. \ fore coxa without coxal bristles ; apical seta about 

 f as long as trochanter. Trochanters 29-38 y. wide ; with 6 oval sensilla ; with 5-10 f.s., and 

 8-10 (average 8-8), 10-14 (average 12) and 12-22 (average 16) h.s. on fore, middle and hind 

 trochanter respectively, the h.s. including 2 minute setae near basal ridge, one small seta on 

 outer margin and 2 long setae of which the longest (apical), on the fore trochanter, is 2-3-3-1 

 (average 2-9) times as long as width of trochanter. Femora of medium width (42-51) y, 

 ratio width to length of hind femur being 1 : 3-8-4-4 (average 4-1) ; each with 6-14 f.s. and 

 1 1-25 h.s. Tibiae 23-40 [i wide, ratio width to length of hind tibia being 1 : n -4-14-2 (average 

 12-6) ; each with 45-68 setae of which 30-60 are h.s. and 8-18 f.s., the latter somewhat longer 

 than width of tibia ; apical spur about the same size on all tibiae. Tarsi 21-27 H wide, hind 

 tarsus 4-3-4-7 (average 4-6) times longer than wide ; each with 4-8 f.s. and 15-26 h.s. ; tarsal 

 digitales subequal, long, about i| times as long as claw. Claws long, hind claw about i£ times 

 as long as width of tarsus ; slightly curved, with small denticle near tip ; ungual digitules 

 subequal, about as long as claw. 



Abdomen 430-500 (average 474) y long and 300-350 (average 331) (x wide. 



Segments I-VII : tergites on segments II— III represented by a small sclerite on each side on the 

 anterior margin, and on VI and VII by a weak plate ; sternites present on segments II, III 

 and VII, represented by weak plates. Caudal extension of segment VII small, rounded, not 

 sclerotized. Dorsal setae : f.s. absent ; h.s. absent on I and usually on II, but usually one 

 on each side on segments III-VII. Pleural setae consisting of h.s. only, which include dorso- 

 pleural setae : 0-2 (average i-o), 2-5 (average 3-7), 4-7 (average 6) and 4-8 (average 5-8) on 

 segments III-VI respectively, and ventropleural setae : occasionally one on III and usually one 

 on each of segments IV-VI. Segment VII with 6-15 (average 11) h.s. Ventral setae : h.s. 

 only, occasionally one on II, usually 2 medially on III, and 4 on each of segments IV-VII. 



Segment VIII with transverse tergite and sternite ; caudal extension forming a small, simple 

 lobe ; glandular pouch with 2 long, pointed setae, whose protruding part is i\-2 times as long 

 as section within pouch. A small IXth tergite sometimes perceptible. Ante-anal setae : 1-2 

 (average i-8) long h.s. Posterior margin with 2-3 (average 2-8) h.s. on each side. 



Genital segment. Penial sheath long, about \ total body length (ratio 1 : 3-8-4-1, average 

 3-9), 376-414 (average 399) y long and 36-40 (average 38) y wide ; lateral sclerotizations not 

 joined anterior to anus ; length of basal rod about § that of aedeagus, the rod extending 

 anteriorly from base of aedeagus for about f of the distance to apex of basal membranous area ; 

 apex of sheath without membranous extension. The area from base of sheath to tip of aedeagus 

 with 19-23 (average 21) small setae ; a cluster of small sensilla occurring ventrally near apex 

 of sheath. Aedeagus long (167-182, average 173 u.), penial sheath longer and basisternum 

 shorter, the ratios being 1 : 2-25-2-42 (average 2-30) and 1 : 0-83-0-98 (average 0-92) respectively. 



Material examined : 9 specimens, collected by G. Matesova on Spiraea hypersifolia 

 L. in the ravine Talgar, Zailiiski Alatau, Kazakhstan, USSR, on 14.vi.57.

Living specimens coral-red in colour, with the sclerotized areas brown and the appendages 

 light yellow, wings with a reddish tinge between anterior margin and first wing vein ; short,
