Santanagryllus
Martins-Neto, 1991
Type
species.
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
).
