Ophryacus
Common names: Mexican horned pitvipers.
Ophryacus is a genus of pit vipers endemic to Mexico. The name is derived from the Greek word ophrys (ὀφρύς), which means "brow", and the Latin word acus, which means "needle", an allusion to the characteristic horn-like scales over the eyes. Currently, three species are recognized and no subspecies.
