|Taxonomic Notes:||This species was considered to be a synonym of Hylopsis platycephalus Werner, 1894, by Lynch (1981b), but this was not accepted by McDiarmid and Savage (1984).|

Listed as Vulnerable because its extent of occurrence (EOO) is 8,641 km2, it is considered to occur in two threat-defined locations, and there is continuing decline in the extent and quality of its habitat outside of protected areas where it occurs in the Sierra Nevada de Santa Marta.
|Previously published Red List assessments:|
|Range Description:||This species is known only from two threat-defined locations in the Sierra Nevada de Santa Marta, in Magdalena Department, Colombia. This is a geographically distinct area where ongoing deforestation for expansion of agricultural production threatens subpopulations outside the borders of protected areas (one location), while the subpopulations within protected areas experience reduced risk of habitat loss (second location). It has been recorded between 700–2,500 m Asl. Its EOO is 8,641 km2.|
Native:Colombia (Colombia (mainland))

|Population:||A survey in 2014 produced observations of four individuals in San Lorenzo (O. Cortés pers. comm. 2014). In the northwestern portion of its range, around 1,600 m Asl, the species appears to be abundant (Bravo-Valencia and Delia 2016). In other parts of the range, at higher altitude (> 2,000 m Asl), it is less common (L. A. Rueda-Solano pers. comm. 2016). Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species occurs on riparian gallery forests. It lays its eggs on leaves and, when hatched, the tadpoles fall in to the water below where they develop further.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||There are no records of this species being utilized.|
The major threat is habitat loss due to agriculture (both crops and livestock) and logging, as well as water pollution due to the fumigation of crops in la Cuchilla de San Lorenzo. This habitat loss is ongoing within the species' range and outside the borders of the protected areas where it occurs (O. Cortés pers. comm. 2014).
Epidemiological surveillance at Estación Experimental de San Lorenzo, Sierra Nevada de Santa Marta has recorded an individual of this species with clinical symptoms similar to chytridiomycosis, although the test for the disease was negative (Rueda-Solano et al. 2016).
This species' range includes Sierra Nevada de Santa Marta National Park and El Dorado Nature Reserve, which was established in 2006 (Fundación ProAves 2006).
Additional habitat protection is needed outside of the protected areas and continued enforcement of these areas will be important for maintaining critical forest habitat within the range.
Research is needed to better understand population trends and current threats.
