Ovenbirds (Furnariidae)
Speckled Spinetail (Cranioleuca gutturata) - HBW 8, p. 298
French: Synallaxe ponctué
German: Fleckenbrust-Baumschlüpfer
Spanish: Curutié Jaspeado
Other common names: D’Orbigny’s Spinetail
Taxonomy: Anabates gutturatus d’Orbigny and Lafresnaye, 1838, Yuracarés (probably Cochabamba), Bolivia.
Relationships uncertain; differs vocally from other species in genus as currently defined. Possible sister-species relationship to C. muelleri suggested by plumage pattern. Proposed race peruviana, from E Peru, described as darker above, paler and less ochraceous below (including underwing-coverts), breast spotting coarser, chin paler yellow, supercilium less pronounced; these characters considered by subsequent authors to represent individual variation, although absence of buff wash on underparts thought by some to permit diagnosis; even if characters do represent geographical ..

Relationships uncertain; differs vocally from other species in genus as currently defined. Possible sister-species relationship to C. muelleri suggested by plumage pattern. Proposed race peruviana, from E Peru, described as darker above, paler and less ochraceous below (including underwing-coverts), breast spotting coarser, chin paler yellow, supercilium less pronounced; these characters considered by subsequent authors to represent individual variation, although absence of buff wash on underparts thought by some to permit diagnosis; even if characters do represent geographical variation, however, specimens from C Peru seem intermediate. Further study may also demonstrate that resurrection of name hyposticta (type locality R Negro, opposite Boavista, in Brazil) for populations of NW Amazonia is warranted. Clearly, reanalysis of variation throughout range is required, and this may indicate that one or both are valid taxa. Tentatively treated as monotypic.
Distribution: SE Colombia (S from W Caquetá), S Venezuela (Amazonas, Bolívar), NE Surinam and N French Guiana S to E Ecuador, E Peru, Amazonian Brazil (W Amazonas E to Amapá, S to Acre and NC Pará) and N Bolivia (S to Cochabamba).
