Ceratophora

The twirler moth genus invalidly described by Heinemann in or around 1870 has been synonymized with Brachmia. Ceratophora was also an emendation for the dinoflagellate genus Ceratophorus (now Neoceratium) and the heteropod genus Cerophora (now Firoloida).

Ceratophora is a genus of agamid lizards found in Sri Lanka. The male has a horn on its snout.
