In this variety the worker and female possess a much more 

 developed lateral tooth to the scape of the antennae than in 

 scabrinodis proper, and the longitudinal keel on its upper side is 

 very distinct. The male is to be known by the longer scape, which 

 is as long as the first five joints of the funiculus taken together.

In my experience whenever these males with long scapes are 

 found, the females and workers in that colony always exhibit the 

 large development of the lateral tooth, etc., and sabuleti no doubt 

 represents the extreme form of development of scabrinodis in this 

 direction.
