 Worker. Head capsule pale yellow, fine, short, rather numerous pilosity, yellow. Post- 

 clypeus rather weakly inflated, Pcl/R], 1-59, Pcl/W, 0-21; left mandible with proximal end of 

 subsidiary marginal tooth separated from molar prominence by pronounced notch. Fore 

 tibia strongly inflated, Ti/T w , 3-08. Mixed segment of gut long, length 5-6 times width of 

 mesenteron at insertion of malpighian tubules; enteric valve seating with three distinct equal 

 lobes, and a short neck connecting it to second pouch of proctodeum ; internal cushions entirely 

 reticulated, membrane beyond cushions with vestigial spicules.

Adaiphrotermes scapheutes may be expected to overlap in its distribution with 

 A. choanensis, from which it differs in the imago by the sinuate posterior margin 

 of the postclypeus and the inconspicuous fontanelle. The worker mandible differs, 

 and the fore tibia is more strongly inflated. Comparison with Adaiphrotermes 

 cuniculator is made in the discussion on that species. 



Holotype 9» imago (queen) and three paratype workers from type-colony only, 

 Zambia: Kitwe, 23. i. 1957 (W. G. H. Coaton) in National Collection of Isoptera, 

 No. TM.3928, Pretoria. 



Only the type-nest-series of this species is known. There is no information on its 

 biology.
