This species can only be compared with gigaiitella Chambers, from 

 which its much smaller size at once distinguishes it; it also lacks the 

 radiating lines towards the apex of the wing. The male is unknown, 

 but nigrostriata is doubtless more correctly referred to Holcocera 

 than to Catacrijpsis.
