Workey. Head capsule pale yellow, pilosity sparse, yellow. Postclypeus weakly inflated, 

 Pcl/VV, 025. Apical teeth of mandibles short, L A /Li, 063, R A /Ri, 082; subsidiary marginal 

 tooth of left mandible clear of molar prominence in surface view, complex ratio, La/Li. L m , 

 10-41; point of first marginal tooth of right mandible slightly behind line of apical to second 

 marginal, anterior edges of marginals about equal in length, R A /Ri.Rm, n-oo. Fore tibia 

 slender, Ti/T w , 573, third apical spur vestigial, extremely minute. Mesenteric junction with 

 proctodeum diagonal; enteric valve seating connected to second pouch of proctodeum by 

 distinct neck, dorsolateral in unopened abdomen; enteric valve cushion in position 1 only 

 sclerotized on distal half, only about one-quarter of total length of cushion protruding beyond 

 tips of spines of other cushions, dilated end fringed with 13-18 elongated spines, rest of length 

 of cushion including unsclerotized base with small spines; cushions in other positions edged 

 with 5-10 elongated curved spines, very sharply tapered so that tips appear almost blunt, 

 and small spines on remainder of cushion ; membranous wall of valve between and beyond 

 cushions with detectable spicules.
