Fore wing: subcosta extending at least nearly to the wing apex; 
Rs with 4 terminal branches; MA forked, MP with at least 3 
terminal branches; CuA with a short terminal fork; CuP more 
extensively developed, with a deep fork shortly after its origin ; 
several anal veins; cross veins distributed generally over the wing, 
not arranged in rows ; anterior margin of the fore wing nearly straight, 
at most very slightly concave. Hind wing: little-known; slightly 
broader than fore wing. Body structure: prothoracic lobes present; 
abdomen slender. 
This family seems closely related to the Spilapteridae, from which 
it differs in having a less developed Rs and CuA. Lack of knowledge
