Paracearagryllus Martins-Neto , n. gen.

Etymology. Quite Cearagryllus .

Type species. Cearagryllus poliacanthus Martins-Neto, 1991 , designated here. Diagnosis. Females. Body relatively robust, length not exceeding 20 mm. Ovipositor length around 10 mm, thin and delicate. Hind tibia bearing relatively long spines. Fore wing with ScP long, slightly curved, not thickened; R parallel to ScP, three-branched; r-m present, close to the wing base.

Discussion. Paracearagryllus Martins-Neto , n. gen. shares morphological characteristics of the three described species of Cearagrylloides n. gen.: from C. perforatorius the curved ScP and R; from C. microcephalus , the origin of MP close to the wing base and distally branched, and from C. previstus , the small body length. P. poliacanthus differs from C. perforatorius in the lack of a sigmoid ScP which is not thickened at its base (the P. poliacanthus curvature of ScP is probably a preservational distortion); differs from C. microcephalus in having MA two-branched, branching at the mid length of the wing (just a distal branch in C. microcephalus ), and differs from C. previstus in having a notably smaller body size and the wings as long as the body. Paracearagryllus poliacanthus also differs from all three species in having a small ovipositor (around 60% of the body length) and a greater number of cubital secondary branches.
