Caiçara and Engenho da Gama, Mato Grosso, Brazil.
One of the small hermits sometimes separated in genus Pygmornis. Similar to P. squalidus and P. subochraceus, but morphological characters indicate closer relationship to P. atrimentalis, P. striigularis, P. griseogularis, P. ruber and P. stuarti. Proposed form P. maranhaoensis, which had been considered a full species or a race of P. squalidus, has been proved to be the adult male plumage (until then undescribed) of present species#R. Exists in two populations which appear to be geographically isolated. Monotypic.
E Bolivia and adjacent SW Brazil (Mato Grosso and E Rondônia); NE Brazil (Maranhão to Ceará, and also recorded in SE Pará and Tocantins).
