Etymology: Pyrrhulina: Greek, pyrrhos = red, with the colour of the fire (Ref. 45335).
More on author: Cope.
Issue
Illustrated by Fowler, 1906 already without its head, the unique holotype has no head, fins, or scales, thus certain identity is difficult. However, it is confused with other species in the literature and its identity needs to be clarified. Marilyn Weitzman, pers. comm. Eschmeyer, 1998: 862; Ortega and Vari, 1986: 11.
