valve seating. Aganotermes oryctes sp. n. is sympatric with A. moretelae and re- 

 sembles it slightly in the imago, but the apical teeth of the mandibles are much 

 longer. 



Adynatotermes moretelae (Fuller) comb. n. 

 (Text-figs 232-240; PI. i, fig. 11) 



Mirotermes (? Procubitermes) moretelae Fuller, 1925 : 191. LECTOTYPE J, Republic of 

 South Africa: Pienaars River. (National Collection of Isoptera, Pretoria) here designated 

 [examined]. 



Imago. Head capsule brown to sepia-brown, darker above ocelli, dark areas often extending 

 as tapering streaks converging to fontanelle; fontanelle small, short oval, about one-third length 

 of ocellus or less, usually raised on slight bump but sometimes flat or slightly depressed, pale 

 brown, often enclosed by dark area; medial spot short oval, equal to fontanelle or slightly 

 larger, raised on more distinct bump, pale brown; postclypeus yellow to yellow-brown, labruni 

 yellow; frontal marks distinct, flat pale brown crescents; antennae pale yellow-brown. Pro- 

 notum, meso- and metanota pale brown to brown; femora pale yellow-brown, tibiae and tarsi 

 yellow. Abdominal tergites, pale brown to brown, sternites pale brown, paler in middle, 

 dorsal and ventra stigmata paler than sclerites; cerci yellow-white. 



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

 large, separated from compound eyes less than half, up to near, own least diameter; postclypeus 

 moderately inflated, Pcl/W, 0-27-0-31, posterior margin bowed, not evenly rounded, median 

 suture distinct. Pilosity of head capsule dense, short, coarse, and uneven in length, not forming 

 a pelt. Other characters in generic diagnosis.
