Taxonomy

Taxonomic note
Premnoplex tatei and P. pariae (del Hoyo and Collar 2016) were previously lumped as P. tatei following SACC (2005 & updates), Sibley & Monroe (1990, 1993) and Stotz et al. (1996).

Population justification: Population densities on Cerro Humo were found to be low (0.8 individuals/ha; Evans et al. 1994). Precautionarily assuming that only around 10-20% of the area of mapped range are occupied to account for the species's rarity (per Remsen 2020), the population may number 1,840-3,680 individuals, roughly equating to 1,230-2,450 mature individuals. To account for uncertainty, the population size is here placed in the band 1,000-2,499 mature individuals. However, given the age of this estimate and the suspected slow decline of the population, an up-to-date estimate is required.
The subpopulation structure has not been formally assessed, but based on its very small range it is tentatively assumed that the species functions as one subpopulation.

Trend justification: This species's population is suspected to be declining slowly. Tree cover within the range is lost at a rate of 3% over ten years (Global Forest Watch 2021). Given the species's strict requirements for wet montane forest, the population may decline faster than the rate of tree cover loss suggests due to the compounding impacts of understorey degradation. Nevertheless, population declines are unlikely to exceed 10% over ten years.
