second marginals approximately equal. Pilosity of head capsule very dense, sepia-brown,

 striction, M/W, 0-26-0-28. Fore tibia with third apical spur distinct, about half length of 

 others.

Worker. Head capsule pale yellow-brown, pilosity yellow-brown, sparse but conspicuous 

 owing to colour. Postclypeus moderately inflated, Pcl/W, 0-27-0-28, Pcl/Ri, 2-21-2-38; 

 apical teeth of mandibles short, La/L|, 0-58-0-61, Ra/Ri, 0-71-0-76; subsidiary marginal tooth 

 of left mandible separated from molar prominence by distinct notch in surface view, complex 

 ratio, La/Li. L m , 13-90-14-83; first marginal tooth of right mandible distinctly behind line of 

 apical to second, its anterior margin slightly more than half length of second, Ra/Ri-Rih. 

 15-09-17-90. Fore tibia weakly inflated, Ti/T Wl 4-35-4-60, third apical spur small but more 

 than one-quarter length of others, not vestigial. Mesenteric junction with proctodeum slightly 

 longer than diagonal, reaching midway through malpighian knot; enteric valve seating dorso- 

 lateral in unopened abdomen, weakly three-lobed, two outer lobes almost form hood over smaller 

 third, connected to second pouch of proctodeum by short but definite neck; membranous 

 wall of valve beyond cushions with sparse minute spicules. 



Measurements (three specimens from three localities) in millimetres.
