Apart from the number of antennal joints there is nothing to 
distinguish the insects included in this genus from those included in 
Schizonycha; with one exception, A ovatula, they have an elon- 
gated, somewhat slender appearance, and the genitalia of the male 
have their counterparts in those of Schizonycha, and are of the 
same type.
