Etymology.A quite Cearagryllus.
Typespecies. Cearagryllus perforatorius Martins-Neto, 1991, designated here. Diagnosis(female). Robust cearagryllids with relatively small head. forewing length equal to the body length; ovipositor long and setiform, longer than the forewing/body length.
Discussion.The Araripe female cearagryllines, although reasonably similar to the male ones, cannot be confidently placed in any of the genera Cearagryllus, Notocearagryllus, Allocearagryllusor Cryptocearagryllus. The generic separation is necessary, although artificial, to prevent mistakes of interpretation. The new genus is useful for paleoecological purposes, as discussed below.
