178 MORPHOLOGY AND TAXONOMY OF ADULT MALES 



Legs : Moderately long and stout ; the fore and the middle legs of subequal length and 

 shorter than the hind legs ; the ratio length of the hind leg to the total length of the body 

 1 : 1 -8-i -9 (1-85). Coxa and trochanter about 40 and 24(1. wide respectively. Femur about 

 31 (x wide ; that of the middle leg shortest and that of the hind leg longest ; the ratio width to 

 length of the hind femur 1 : 4-9-5-2 (50). Tibia about i8jj. wide ; with 2 apical spurs and 

 2-3 smaller spines ; in the fore leg the femur slightly shorter than the tibia, the ratio their 

 lengths 1 : 1-1-1-2 (1-17). Tarsus about i8(i wide ; tarsal digitules apically knobbed, about 

 29 (i. long. Claw broad at base and abruptly tapering to a sharply pointed tip ; ungual 

 digitules apically knobbed. The following table shows the lengths of the leg segments (in 

 microns) and the number of setae on each :

Abdomen : 304-380 (357) ^ long and 251-289 (266)}! wide. Tergites of segments I and II 

 small ; that of segment VIII large, anteriorly bounded by a transverse stripe of heavy 

 sclerotization. Sternites of segment VIII also bounded laterally by a longitudinal, similarly 

 heavy sclerotization. Ostioles absent. Abdominal setae on each side : Dorsal setae 4-6 on 

 segment I, 4-5 on segments II to V, 2-4 on segments VI and VII, and one slightly longer seta 

 on segment VIII. Pleural setae 5-7 on segments I to VII and 2-3 on segment VIII, including 

 one slightly longer seta. Ventral setae 1-2 on segment II, 2-3 on segments III to VII, and 

 always 2 on segment VIII. 



Glandular pouches small ; setae of glandular pouch include a pair of 107-122 (ii3)[x long tail 

 setae, i.e. the ratio their length to the total body length 1 : 7-7-9-8 (8-7). 



Genital segment : Genital capsule comparatively large, 140-153 (146)^ long and 82-92 (85) [x 

 wide, the ratio being 1-6-1-9 (1-7) : 1, and the ratio its length to the total length of the body 

 1 : 6-6-6-9 (6-7). Style rather straight in lateral view, with a pointed apex. Anal opening 

 about i8jx in diameter. Aedeagus with the ventral margin well sclerotized ; internal genital 

 aperture large. Setae of genital segment : Dor sally 2 long setae always present on each side of 

 the style near its apex ; ventrally 3 smaller setae occur on each side of the genital capsule. 



Material : 7 specimens examined, collected by N. S. Borchsensius, on Buxus 

 sempervirens, in Abhasia, U.S.S.R., in 1932 (no exact date given).
