Cerci of $ as long as width across base, slightly mamilliform conical. 



Pilosity of vertex, one or two long bristle-like setae and sparsely scattered shorter hair-like 

 setae, with a few more bristle-like setae around eyes and ocelli (Text-fig. 114). 

 Other characters given in generic discussion.

 Soldiers. Major soldier : head capsule orange to ferruginoi 

 pitch black with paler tip. Pronotum, antennae and abdominal 

 femora of legs brown, tibiae and tarsi yellow. Abdominal sternites pale brown. 



Head capsule in plan view constricted behind antennae, posterior margin regularly rounded ; 

 nose conical. In profile straight or slightly concave to behind antennal socket, then abruptly 

 raised and rounded ; nose shorter than rest of head capsule, measuring from hind margin of 

 antennal socket, angle of nose cone 15-20 degrees ; antennae 13 segmented, II and IV subequal, 

 shorter than V, III and VI subequal and longer than V. Head setae consist of 6-8 at nose tip, 

 and a bilaterally placed pair of small setae on vertex, with very few scattered minute setae on 

 dorsal surface. 



Abdominal tergites with very sparse scattered minute setae, slightly longer on posterior 2-3 

 segments ; sternites with sparse short setae and longer setae up to 3 times length of short on 

 posterior margins. Minor soldier : colour and pilosity, exactly as in major soldier. Head 

 capsule in plan view more sharply constricted behind antennae. In profile concave, slightly 

 sinuate, or indented in front of smaller posterior lobe of head ; nose shorter to equal in length to 

 rest of head capsule, measuring from hind margin of antennal socket, angle of nose cone 10-17 

 degrees ; antennae 12-13 segmented, usually 13.

Variation. Like F. mallvi, this sp< 



;cies has proved to have relatively little variation over its 



comparatively short geographical ran 



ge. The most variable caste is the minor soldier. 





This species is retained in Fulleritermes in spite of its distinct soldier dimorphism 

 because of its very close similarity in all respects, morphological and ecological, to 

 F. tenebricus and F. contractus, with which latter species it has in the past been
