Population justification: The global population size has not been quantified, but the species is described as fairly common to common (Stotz et al. 1996, Krabbe and Schulenberg 2020).
Currently, c.1,000,000 ha within its range are covered by forest with 75% canopy (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). Assuming that this species occurs at a similar density than a congener (S. robbinsi in Ecuador: 2 mature individuals in 7 ha of forest; Hermes et al. 2017), and further assuming that half of the forests are occupied, the population may number c.140,000 mature individuals. This number however requires confirmation.
Based on the spatial spread of records (eBird 2021) and accounting for the generally low dispersal abilities of tapaculos (Krabbe and Schulenberg 2003), it is conceivable that the species forms several subpopulations.

Trend justification: The species is restricted to the understory of mature humid forests (Krabbe and Schulenberg 2020) and as such it is at risk from the degradation and loss of its habitat. Within the range, tree cover loss is minimal (<1.5% over ten years; Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein); the population is therefore suspected to be stable in the absence of evidence for any declines or substantial threats.
