Typical Antbirds (Thamnophilidae)

White-fringed Antwren (Formicivora grisea) - HBW 8, p. 613

French: Grisin de Cayenne German: Braunrücken-Ameisenfänger Spanish: Hormiguerito Coicorita
Other common names: Black-breasted Antwren

Taxonomy: Turdus griseus Boddaert, 1783, Cayenne, French Guiana.
Morphological, vocal and molecular studies indicate that, with exception of F. iheringi, all species placed in current genus form a well-defined group. Recent extensive morphological and vocal study suggests that closest relatives of present species are F. rufa and Stymphalornis acutirostris; close relationship with former also supported by genetic study. Geographical differences in voice and striking differences in female plumages strongly suggest that some races represent separate species; further study required. On other hand, fumosa possibly indistinguishable f.. View all taxonomy...

Taxonomy: Turdus griseus Boddaert, 1783, Cayenne, French Guiana.
Morphological, vocal and molecular studies indicate that, with exception of F. iheringi, all species placed in current genus form a well-defined group. Recent extensive morphological and vocal study suggests that closest relatives of present species are F. rufa and Stymphalornis acutirostris; close relationship with former also supported by genetic study. Geographical differences in voice and striking differences in female plumages strongly suggest that some races represent separate species; further study required. On other hand, fumosa possibly indistinguishable from intermedia. Described form deluzae known from single specimen from Rio de Janeiro (Brazil); possibility that it represents a distinct race considered unconfirmed. Eight subspecies recognized.

Subspecies and Distribution:

  • alticincta Bangs, 1902 - Pearl Is, S Panama.
  • hondae (Chapman, 1914) - NW Colombia (Atlántico S to N Antioquia and Bolívar, S in Magdalena Valley to Huila).
  • intermedia Cabanis, 1847 - N Colombia (Magdalena, La Guajira, César) and N Venezuela (N Zulia E to Sucre and Monagas, including Margarita I); also Chacachacare I, off Trinidad.
