Family Inocelliidae (Square-headed Snakeflies)
One nearctic genus, Negha, with three species (1).
Generally larger than most raphidiids , with longer and thicker antennae (especially basally). Pterostigma lacks a cross-vein and is darker than that of raphidiids. (2)
Suggested by the family name, Inocelliidae lack ocelli (simple eyes). An illustration of the wing venation can be seen on p.471 in Borror & Delong (3)
For much more information on this group, see the info page for order Raphidioptera.
