Diagnosis
Hadronotus circus shares the character state of triangular frontal depression with a wide base with H. galdikasae sp. n. However, it differs from H. galdikasae in having a central keel extending the entire length of frontal depression on frons, while in the latter the central keel is incomplete.
Remarks
This species is reported for the first time from India.
