Type species: Eotilla mickeli Schuster, 1949 , by original designation.

Diagnosis. Modified from Torréns et al. (2012).

Male. Macropterous. Head with ocelli. Antennal scape with a ventral longitudinal carina. Horizontal face of prosternum weakly projecting anteriorly, without a projection posteriorly. Mid coxae moderately separated by a distance equal to half maximum width of femur. Fore wing with two submarginal cells. Hind wing with median cell obliquely truncate at apex, not reaching level of origin of distal hamuli-group; median cell with two veins arising from it (RS and Cu). Tarsal claws smooth, without ventral tooth (see Fig. 11 in Schuster 1949). Genitalia with basal ring anteroventrally broadly emarginate.

Female. Apterous. Head without ocelli. Mandible with small preapical denticle on inner edge. Pronotum trapezoidal, with sides strongly convergent to posterior margin; humeral tubercle scarcely developed. Mesopleural longitudinal carina reaching to anterior half of sclerite or beyond but never complete. Mid coxae widely separated by a distance of 1.3 × maximum width of mid femur. Tarsal claws smooth, without ventral tooth. S6 with lateroposterior margin with distinct denticles, although sometimes weak.
