Systematics History

The various subspecies of Rufous-brown Solitaire have, over the years, been elevated to full species or treated as subspecies as described here. Despite the fact that more than one species is probably involved, at present a formal splitting is awaiting careful, formal evaluation of the evidence (10). del Hoyo and Collar (11) elevated each subspecies to species based on plumage, morphometric, and vocal differences (12, 13).

Subspecies

Four subspecies recognized (14).


EBIRD GROUP (MONOTYPIC)

Rufous-brown Solitaire (Chestnut-throated) Cichlopsis leucogenys chubbi Scientific name definitions

Systematics History

Cichlopsis chubbi Chapman, 1924, American Museum Novitates no. 138 p. 15.—Mindo, Huila, western Ecuador (15).

Distribution

Western slope of the Western Andes in southwest Colombia (16, 17, 18) and northwestern Ecuador in Esmeraldas and Pichincha (19, 20, 21).

Identification Summary

Subspecies chubbi differs from nominate leucogenys in its darker chestnut throat, chestnut-tinged versus pale gray belly, and rich chestnut undertail coverts (1).


EBIRD GROUP (MONOTYPIC)

Rufous-brown Solitaire (Peruvian) Cichlopsis leucogenys peruviana Scientific name definitions

Systematics History

Cichlopsis leucogenys peruvianus Hellmayr, 1930, Novitates Zoologicae 35 p. 265.—Perene, Dept. Junin, Peru (22).

Distribution

Local in Huánuco, Pasco, and Junín on the eastern slope of the Andes in Peru (23, 24).

Identification Summary

Subspecies peruviana is most similar to chubbi, differing from chubbi by its pale rufous-tinged ochre throat, blackish lores, pale tawny lower breast, and vague pale rufous pre-ocular supercilium and eye-ring (1).

EBIRD GROUP (MONOTYPIC)

Rufous-brown Solitaire (Guianan) Cichlopsis leucogenys gularis Scientific name definitions

Systematics History

Cichlopsis gularis Salvin and Godman, 1882, Ibis (4) 6 (21) p. 76.—Merume Mountains, British Guiana [= Guyana] (25).

Distribution

Tepuis (mesas) of southeastern Venezuela (26, 27, 28, 29), Guyana (30), and western Suriname (31, 32).

Identification Summary

Subspecies gularis differs from nominate leucogenys in its much paler (buffy ochre versus dull chestnut) throat, paler brown breastband, and milky rufous versus olive-tinged pale gray undertail coverts. From chubbi it differs in its buffy ochre throat; paler gray underparts, and its much paler milky-rufous undertail coverts. Subspecies gularis differs from peruviana in its slightly more rufous but narrower pale throat patch that is bordered by darker brown malars, its grayish versus buffy-brown belly, and its pale undertail coverts (1).


EBIRD GROUP (MONOTYPIC)

Rufous-brown Solitaire (Rufous-brown) Cichlopsis leucogenys leucogenys Scientific name definitions

Systematics History

Cichlopsis leucogenys Cabanis, 1851, Museum Heineanum 1 p. 54.—Brazil (33).

Distribution

Nominate subspecies. Endemic to southeastern Brazil in Bahia, Minas Gerais, and Espírito Santo (34, 35, 36, 37, 38).

Identification Summary

Described in Plumages.

Related Species

Cichlopsis is most closely related to the Entomodestes solitaires, but together these are only distantly related to the Myadestes solitaires; Cichlopsis and Entomodestes are instead most closely related to the nightingale-thrushes (Catharus), Aztec Thrush (Ridgwayia pinicola), and Wood Thrush (Hylocichla mustelina)(39).

Hybridization

None reported.
