THE SOLDIERLESS TERMITES OF AFRICA 



185 



termes and some A nenteotermes, but the structure is different in many respects. In the 

 analysis of the similarity matrix, Anaorotermes comes out next to Ateuchotermes by 

 single linkage clustering. Median sorting places it closer to Aderitotermes, and 

 when the latent vectors of the principal co-ordinates analysis are examined, it shows 

 relationships to Alyscotermes, Amicotermes and Ateuchotermes in the first six. 



In the imago caste, Anaorotermes is distinguished from Ateuchotermes and Aderito- 

 termes by its dense irregular head pilosity which does not form a pelt, and from 

 Alyscotermes, Astalotermes and Astratototermes by its oddly shaped almost triangular 

 fontanelle. Amicotermes has longer apical mandibular teeth. It is unlikely to be 

 confused with any other genus. In the worker caste, the enteric valve armature 

 is so distinct and characteristic that no comparisons are necessary.
