||c. 11 cm. A typical Scytalopus tapaculo, predominantly slate-grey all over with some buff-brown barring on the belly. Similar spp lacks distinguishing plumage features. Best identified on voice. Voice the song is amongst the simplest of any Scytalopus, consisting of a single note repeated at a pace of 4-5 per second usually given in bouts of 2-5 phrases.

This newly described species has a small population and a very small, severely fragmented range at two locations. Its range and population are likely to be declining because of continuing habitat destruction. It is therefore classified as Endangered.

|Range Description:||Scytalopus rodriguezi was described in 2005 from the head of the Magdalena Valley on the east slope of the Cordillera Central mountains of Colombia. Several records of a Scytalopus species in the Serranía de los Yariguíes (representing a 580 km northward range extension), have recently been described as subspecies yariguiorum (T. Donegan in litt. 2007, D. Willis in litt. 2007, Donegan et al. 2013). The nominate subspecies is known from several locations including the Finca Merenberg Natural Reserve, San Agustín municipality, Huila department, and Serranía de las Minas, a ridge 15 km SSE of Finca Merenberg. It was hypothesised that the species may also occur on the East Andes side of the valley; this seems to be supported by the recent re-examination of a museum specimen collected at La Palma, Huila, which is consistent with rodriguezi based on plumage and biometrics (T. Donegan in litt. 2006). The subspecies's range is believed to be very small, with its stronghold centred on Serranía de las Minas. Much habitat at suitable elevations has already been cleared with an estimated 169 km2 remaining and deforestation continues, suggesting that the species may be declining rapidly. Subspecies yariguiorum has been recorded at three localities on both slopes of the Serranía de los Yariguíes (Donegan et al. 2013). There are no records of the species from the intervening departments of Meta, Caquetá, Cundinamarca, Boyacá or Santander.|

|Population:||The population is estimated to be in the band 2,500-9,999 individuals in total, equating to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 individuals.|
Trend Justification: A rapid and ongoing population decline is suspected, based on rates of habitat loss at the elevations from which the species has been recorded within its very small range.
