Systematics History

Described as Tanagra (Tachyphonus) sanguinolentus (Lesson 1831: page 107) (17). It later was transferred to the genus Ramphocelus Desmarest 1805 by Bonaparte (18).

Sclater and Salvin (19: pages 21 and 155), however, later erected the genus Phlogothraupis, with sanguinolentus as the type (and sole) species.

Since then, sanguinolentus variously has been been classified in Ramphocelus (e.g., 20, 21, 22, 23), or in Phlogothraupis (e.g., 3, 24), based on differences in bill shape and the degree of sexual dimorphism between sanguinolentus and other species of Ramphocelus (although see the comments in 20: page 310, footnote 2), and also on differences in plumage sequence, voice, social systems, and eggs (9). See also Related Species.

Geographic Variation

Very slight.


Two subspecies are generally recognized in Crimson-collared Tanager, though some have considered it monotypic (25); the subspecies differ only in size, which probably varies clinally rather than discretely.


Ramphocelus sanguinolentus sanguinolentus

Systematics History

Described as Tanagra (Tachyphonus) sanguinolentus (Lesson 1831: page 107) (17).


Southeastern Mexico (from Veracruz, northern Oaxaca, Tabasco, and Quintana Roo) south through Belize to Honduras.


See Plumages.


Ramphocelus sanguinolentus apricus

Systematics History

Described as Phlogothraupis sanguinolentus aprica (Bangs 1908) (26: page 31).


Caribbean slope of eastern Honduras south to northwestern and central Panama, locally on Pacific slope in northern Costa Rica.


Similar to nominate sanguinolentus, but smaller (26).

Related Species

The Crimson-collared Tanager is part of the very large and diverse tanager family (Thraupidae), which itself is part of the extremely diverse radiation of songbirds in the New World with nine-primaries (27, 28, 29, 30). Within this large and diverse group, phylogenetic analyses using DNA sequence data has shown that Crimson-collared Tanager appears to be sister to the rest of the members of Ramphocelus (27, 29 ,30). This pattern of relationships is compatible with either recognizing a monospecific Phlogothraupis or with including sanguinolentus in Ramphocelus, but modern authorities continue to prefer retaining sanguinolentus in Ramphocelus (31).

Ramphocelus is sister to the genus Tachyphonus (T. coronatus Ruby-crowned Tanager, T. rufus White-lined Tanager, and T. phoenicius Red-shouldered Tanager) (28, 29).
