MORPHOLOGY AND TAXONOMY OF ADULT MALES 



Tendon-like apodeme absent or very short. Cranial apophysis of medium length ; apex trun- 

 cate or rounded, not reaching level of anterior margin of ventral eyes. Mouth opening irregular. 

 Anterior tentorial pits present, situated anterolateral to mouth opening. 



Antennae io-segmented, filiform ; 996-1060 (average 1018) y. long, i.e. longer than half body 

 length (ratio 1 : 1 -37-1 -52, average 1-45), longer than posterior leg (ratio 1 : 1 -38-1 45, average 

 1-41) and longer than penial sheath (ratio 1 : 3-31-3-49, average 3-41). Scape 42-49 (average 47) 

 [x long and 44-48 (average 46) (x wide, with 3 h.s. Pedicel with distinct, polygonal, dorsal 

 reticulation ; 49-69 (average 57) pt long and 38-42 (average 39) u. wide ; with 2-5 (average 3 -4) f.s., 

 3-7 (average 4-9) h.s. and a sensillum placodeum. Segment III somewhat club-shaped, with a 

 rugose surface ; 4-3-6-0 (average 5) times longer than wide (99-118, average 113 \l long and 

 19-25, average 22 \i wide) ; with 3-9 (average 5-4) f.s. of medium length, 1-2-1-7 (average 

 1-4) times longer than width of segment ; with 1-3 usual sensilla basiconica. Segments IV-IX 

 cylindrical, rugose ; lengths of these segments (in jj.) 137-156 (average 148), 133-156 (average 

 J 45). I 33 _I 63 (average 146), 103-118 (average in), 84-99 (average 90) and 72-87 (average 82) 

 respectively, all of about the same width, varying from 19 to 23 (x and with 13-21 (average 18), 

 19-23 (average 21), 20-32 (average 26), 18-27 (average 22), 13-25 (average 18) and n-17 

 (average 15) f.s. respectively, but no h.s. ; antennal bristles on segments VIII— IX not markedly 

 different from f.s. Segment X : terminal part not constricted ; 72-89 (average 80) y. long and 

 19-22 (average 20) \i wide ; carrying 6-12 (average 9-1) f.s., 3 capitate subapical setae and 5 

 antennal bristles of which the 3 long ones are about f as long as the segment and the 2 short 

 ones about half as long as the f.s. ; with 2 sensilla basiconica ventrally, one near apex and the 

 other more proximal. 



Thorax 448-502 (average 473) \i long.
