Libya? : " Tripoli ", no date (Walker). 



A total of 146 nest series were examined and all material is in the British Museum 

 (Natural History) unless otherwise stated. 



T.oeconomus was recognized by Sjostedt (1925a) as occurring from the Sudan across 

 to Ghana, and further records have extended the range to include vegetation types 

 ranging from forest-savannah mosaic, to the Sahel and even in the case of the Port 

 Sudan record, subdesert steppe (Keay et al., 1959, types 8, 16, 17, 20, 25, and 31). 

 The specimen recorded as T. trinervins by Walker (1853) from " Tripoli " has been 

 examined, and is undoubtedly T. oeconomus. There must be considerable doubt 

 attached to the locality from which it was recorded. According to Capra (1938), no 

 other Trinervitermes has been found in North Africa, and it seems probable that this 

 specimen originated in the Sudan. 



The wide distribution of this species may partly be explained by its habit of 

 commonly building its low wide mound in shaded or sheltered locations, and often 

 occupying parts of mounds of various species of Macrotermitinae.
