Worker. Head capsule pale yellow, pilosity yellow, 

 conspicuous. Postclypeus strongly inflated, Pcl/W, 

 teeth of mandibles fairly short, La/Li, 0-64-0-66, Ra/Ri, 0-84-0-89; subsidiary marginal tooth 

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

 ratio, La/Li. L m , 13-89-14-30; point of first marginal tooth of right mandible distinctly behind 

 line of apical to second marginal, anterior edge of first marginal shorter than that of second, 

 Ra/Ri Rm, 18-20-19-20. Fore tibia weakly swollen, Ti/T w , 4-11-4-23, third apical spur approxi- 

 mately half length of other two. Mesenteric overlap with proctodeum more than four times 

 as long as width of mesenteron at insertion of malpighian tubules, posterior end of mesenteron 

 slightly swollen; enteric valve seating with two weakly developed opposed lobes, connected 

 to second pouch of proctodeum by a short but distinct neck, lateral in unopened abdomen; 

 internal cushions of enteric valve in positions 1 and 2 retracted, very small with scaly surface 

 or at most one or two small spines ; position 3 produced through valve opening, tapering distally, 

 armed with 10-12 elongated pectinate spines around the edge, and other prominent spines on 

 the posterior ends of scales on the proximal part of the cushion; position 4 retracted, but about 

 twice as large as positions 1 and 2 and armed with prominent spines on posterior edges of scales; 

 membranous wall of valve between and beyond cushions with sparse minute spicules.
