Etymology: Pyrrhulina: Greek, pyrrhos = red, with the colour of the fire (Ref. 45335). More on author: Myers.
This species is a synonym of Pyrrhulina australis Eigenmann & Kennedy, 1903 in Eschmeyer (CofF ver. May 2011: Ref. 86870) following Zarske & Géry (2004). Ongoing revision will resolve potential taxonomic problems.
