All monkeyflowers with laciniate-lobed corollas have generally been identified as Mimulus dentilobus B. L. Robinson & Fernald, but these occur as three, morphologically distinct, widely allopatric population systems, each of which is regarded as a separate species (G. L. Nesom 2012g). Erythranthe dentiloba (B. L. Robinson & Fernald) G. L. Nesom, which is endemic to Mexico, is the only one of the three with an allogamous breeding system. Erythranthe parvula is restricted to Arizona and New Mexico except for one locality in northern Sonora, Mexico. Erythranthe chinatiensis is the third species of the group.
