Imago. (Queen, colours probably faded.) Head capsule brown, sepia-brown above ocelli; 

 fontanelle only slightly smaller than ocellus, elongate oval, slightly raised, yellow-brown; 

 medial spot oval, about half size of fontanelle, slightly raised, coloured as head; postclypeus 

 yellow-brown, labrum yellow; frontal marks very distinct, slightly depressed yellow-brown 

 crescents; antennae yellow-brown. Pronotum, meso- and metanota yellow-brown, transverse 

 sutures weakly developed; femora pale yellow-brown, tibiae and tarsi yellow. Abdominal 

 tergites yellow-brown with darker dorsal stigmata, ventral stigmata, and sternites pale yellow- 

 brown, paler in middle; cerci yellow. 



Posterior margin of head capsule not quite evenly rounded, slightly undulating; ocelli medium 

 sized, separated from compound eyes by three-quarters own least diameter; postclypeus weakly 

 inflated, Pcl/W, 0-25, posterior margin broadly arched, median suture distinct. Apical teeth 

 of mandibles short, La/Li, 0-53, Ra/Ri, 0-70; subsidiary marginal tooth of left mandible widely 

 separated from molar prominence in surface view, complex ratio La/Li. L m , 6-oo; points of 

 apical and marginal teeth of right mandible approximately in line, anterior edge of first marginal 

 slightly shorter than that of second. Meso- and metanota moderately wide at constriction, 

 M/W, 0-30. Pilosity of head capsule, yellow-brown, short setae rather even, almost forming a 

 pelt, obscured by numerous uneven emergent setae.
