This species is very interesting as carrying to the 

 greatest known extent amongst Longicornia that peculiar 

 modification of the head in which the front forms with 

 the upper side a very acute angle, and in which the eyes 

 are simple and placed far back from the insertion of the 

 antennae. 



In the British Museum collection there is a single 

 specimen from the Nyassa region.
