In keying out the imago caste, Asagarotermes with its narrow meso- and metanotal 

 constrictions comes nearest to Anenteotermes and Group I Astalotermes. It is larger 

 than nearly all of these and can be distinguished from the one or two largest species 

 by its longer apical mandibular teeth. Aganotermes, which combines size, narrow 

 nota and long apical teeth, has the subsidiary marginal tooth of the left mandible 

 level with the edge of the molar prominence, not clear of it as in Asagarotermes. It 

 also has a shorter postclypeus and ocelli further from the eyes. 



The worker caste of Asagarotermes is so distinctive in its enteric valve armature 

 that there is no necessity for detailed comparisons with other genera. 



Asagarotermes coronatus sp. n. 



(Text-figs 493-502 ; PI. 7, figs 4 & 5) 



Imago. Head capsule dark sepia-brown, darker above ocelli; fontanelle less than half size 

 of ocellus, oval, slightly depressed, more so at anterior end, coloured as head; medial spot equal 

 to fontanelle or smaller, oval, flat, coloured as head; postclypeus sepia-brown, labrum yellow- 

 brown; frontal marks distinct, semicircular, flat, coloured as head; antennae brown. Pronotum 

 meso- and metanota, sepia-brown; femora brown, tibiae yellow-brown, tarsi yellow. Abdominal 

 tergites brown, dorsal stigmata slightly darker, sternites pale brown, paler in mid-line, ventral 

 stigmata darker. Cerci yellow. 



Posterior margin of head capsule evenly rounded; ocelli medium-sized, separated from com- 

 pound eyes by two-thirds, up to only slightly less than own least diameter; postclypeus moder- 

 ately inflated, Pcl/W, 0-29-0-31, posterior margin bowed, not evenly rounded, median suture 

 distinct. Pilosity of head capsule dense, uneven, thick setae, not forming a pelt.
