Santanagryllus hesselae Martins-Neto, 1991 by original designation. Remarks. Santanagryllus Martins-Neto differs from Cearagryllus , the closest genus, in having a straight anterior margin of the speculum, twice as long as the posterior margin. Additionally, in Santanagryllus R and CuA are sinuous and distally convergent. Santanagryllus shares with Notocearagryllus a wider area below the speculum, differing however in the shape of the speculum (rather trapezoidal in Santanagryllus , squarerounded in Cearagryllus and Notocearagryllus ).
