Dryophylax phoenix

Dryophylax phoenix is a species of snake in the family Colubridae. The species is endemic to Brazil.

Etymology
D. phoenix is named after the Greek mythological bird, the Phoenix (φοῖνιξ phoinix; Latin: phoenix, fenix), which dies in flames and rises from ashes. It is referenced due to the loss of the original holotype of thiss species, in a fire that destroyed 90% of its herpetological collection. Some specimens were rescued and the data from the lost specimens was preserved. Some common names include Cobra-Espada and Corre-Campo (Portugese).
