Taxonomic note
A. lilliae (Handbook of the Birds of the World and BirdLife International 2020) was previously recognised as Lepidopyga lilliae (del Hoyo et al. 2014), however Ornelas et al. (2014) found one Lepidopyga species, L. coeruleogularis, to be an Amazilia. On the basis of this finding all three Lepidopyga were moved to Amazilia.

Population justification: The population size is low and the species is described as either rare or sporadic at the few known localities (Luther 2020). Surveys in Isla de Salamanca National Park between 2006 and 2007 found a population density of 6 individuals/ km² (González Brun 2007). Assuming that the species occurs at a similar density throughout the range and that only 10% of the range is occupied to account for the species's rarity and localised distribution, the population may have numbered around 1,050 individuals in 2007, equating to 700 mature individuals. Assuming further that the population is declining at a rate of 30-49% over ten years (Renjifo et al. 2016), the current population may number 285-440 mature individuals.
In view of the species's dispersal abilities and the distribution of records, all individuals are thought to belong to the same subpopulation.

Trend justification: The species is thought to be declining rapidly owing primarily to habitat loss. Between 2001 and 2011, 39.1% of mangrove and flooded forest have been lost, and it is assumed that this is continuing at the same rate into the future (Renjifo et al. 2016). Under the assumption that population declines are roughly equivalent to rates of habitat loss, the species is inferred to be declining at 30-49% over ten years.
