Possibly closest to Emurena which it matches in the type of androconial patches; 

 the yellow, brown and yellowish white coloration; and in the colour-pattern of 

 the antennae and legs. The male genitalia of the two genera, however, have few 

 characters in common. 



There are three species in this genus: flavescens, known from much of tropical 

 South America; pseudoflavescens , known only from Brazil (Minas Gerais state); 

 and aureogrisea from eastern Peru. 



Nothing is known about the early stages.
