Taxonomic note
Phyllanthus atripennis, P. rubiginosus and P. bohndorffi (del Hoyo and Collar 2016) were previously lumped as P. atripennis following Dowsett & Forbes-Watson (1993) and Sibley & Monroe (1990, 1993).

Population justification: The population size has not been quantified, but it has been described as 'rare to fairly common' (Collar et al. 2020).
Trend justification: The species is suspected to be declining in line with habitat loss. Between 2016-2019, this species's range experienced forest cover loss of 12% (Global Forest Watch 2020). Projected forward over three generations this equates to a loss of 34%. Assuming that the population declines at a similar rate to forest loss, the past and future rate of decline is suspected to fall in the band of 30-49% over three generations.
