Subspecies
Ramphocelus passerinii (Sibley and Monroe 1990, 1993) has been split into Scarlet-rumped Tanager (Ramphocelus passerinii) and Cherrie's Tanager (Ramphocelus costaricensis) following AOU (1998).
Often treated as conspecific with Cherrie's Tanager (Ramphocelus costaricensis), but recent DNA studies suggest that they can be regarded as separate species. DNA studies indicate that both are monophyletic and, although levels of divergence within the two taxa (0·1%, 0·6%) are much less than divergence between them (1·8%), this level of interspecific divergence is lower than that between most species of tanager (c. 2·4 - 4·0%). Also, visual differences between the two are minimal (involving mainly females), and only minor vocal differences have been demonstrated. Further evaluation of these taxa may be required.
The following 2 subspecies are recognised:
passerinii Bonaparte, 1831 - Southern Mexico to Panama.
costaricensis Cherrie, 1891 - Pacific slope of southern Costa Rica (Puntarenas) and western Panama. Considered by some authors to be a distinct species, Cherrie's Tanager (Ramphocelus costaricensis).
