Diagnosis

Hadronotus strongist is similar to H. divergens sp. n., but differs from it by the absence of temples and having a sharp vertex which is distinctly raised above dorsal margin of eye in frontal view, while in H. divergens temples are distinct and vertex is not sharp but evenly rounded and not raised above dorsal margin of eye in frontal view.

Remarks

This species is reported for the first time from India.
