The Táchira Antpitta was last seen in 1956. Between 1955 and 1956 the ornithologists
William Henry Phelps andAlexander Wetmore collected four specimens in the type locality at thehacienda "La Providencia" at theRio Chiquita in the south-western part of Táchira,Venezuela . The type locality is located in theEl Tamá National Park where some suitable habitat still remains. However, between 1990 and 1996 thecloud forest in the Rio Chiquita valley - including parts of the national park and the type locality - was entirely changed intocoffee plantation s below 1,600 m ASL, and largely cut down for vegetable gardens between 1,900 and 2,200 m ASL.Despite extensive searches from 1990 to 1996, this species has not been observed since more than half a century. It was formerly classified as
Endangered by theIUCN [BLI (2004)] . But with current research failing to relocate this species, it is uplisted toCritically Endangered status in 2008 [BLI (2008)] .Footnotes
