i : I-I-I-2 (1-17). Tarsus about i8(x wide ; tarsal digitules absent. Claw gradually tapering 

 to a sharply pointed tip ; ungual digitules fine. The lengths of the leg segments (in microns)

Abdomen : 464-707 (623)^ long and 319-365 (350) (x wide. Tergites of segments I and II small ; 

 those of segments VIII and IX + X well defined. Sternites of segment VIII small. Ostioles 

 entirely absent. Abdominal setae on each side : Dorsal setae 2 on segment I, 2-3 on segments 

 II to VII, and absent on segment VIII. Pleural setae 2 on segment I, 2-3 on segment II, 3-4 

 on segments III to V, 3-5 on segments VI and VII, and 2-3 on segment VIII. Ventral setae 

 2 on segment II, 3-5 on segments III to V, 2-3 on segments VI and VII, and absent on segment 

 VIII. 



Setae of glandular pouch include a pair of 122-153 (137)^ long tail setae and one seta about as 

 long as the abdominal setae, i.e. the ratio length of tail setae to the total body length 1 : 8-2- 

 n-9 (10-5). 



Genital segment comparatively small ; style rather straight in lateral view, with a pointed 

 apex. Penial sheath 134-146 (140)^ long and 92-98 (95)10. wide, the ratio being 1-4-1-6 (1-5) : 1, 

 and the ratio its length to the total length of the body 1 : 9-2-11-5 (10-3). Basal ridges of
