Hadronotus diadematis (Mineo) comb. nov.

Gryon diadematis Mineo, 1983a: 18, 19 (original description, keyed); Johnson, 1992: 381 (cataloged, type information).

Comments.

We transfer this species to Hadronotus based on the description of the "completely enframed frontal depression... connected to the anterior ocellus by a ridge" provided in Mineo (1983a) and examination of a paratype specimen.
