Diagnosis Body medium-sized for Aemodogryllini . Hind femur with inner spines on ventral surface. Male abdominal tergites without any processes. Male epiproct extended backward, distinctly longer than paraproct, quadrangular or pentagonal. Male paraproct slightly enlarged. Dorso-lateral lobes of male genitalia distinctly sclerotized. Male subgenital plate bilobed in the apical area. Female abdominal tergites without outgrowth. Remarks The new genus can easily be distinguished from other known genera of Aemodogryllini by the shapes of the male epiproct, dorso-lateral lobes of the male genitalia, and the male subgenital plate.
