Genus ANOPLOTERMES Fritz Muller. 



Species of this genus have no soldier caste. But few species are 

 known and most of these are from America. Certain species in the 

 Tropics build large mounds. 



The worker caste is usually of a dirty gray color, and workers 

 have the habit of moving about in files or lines.
