In the male the 7th ventral plate is broad and rounded 

 at the extremity, towards which part the punctures become 

 more sparing, so that at the apex, in the middle, they are

 a deep, elongate trough, tcrn:iinated at its extremity by a 

 curved, elongate spine. 



Tapajos ; only one individual.
