Known only from two 19th century trade skins labelled as from 'Bolivia', there remains the possibility that the species has been subsequently overlooked. Given the complete lack of modern information regarding the species, the species is classified as Data Deficient.

Geographic Range [top]

Range Description:Discosura letitiae is known from two specimens simply labelled as from Bolivia, and taken prior to 1852 when it was described (Bourcier and Mulsant 1852, Butchart and Bird 2010). A study investigating the possibility that the specimens represented immature or variant plumages of Racquet-tailed Coquette Discosura longicauda (probably the most closely related species) or a hybrid form validated the original treatment as a separate species (Graves 1999). It could occur in the ornithologically poorly known Amazonian lowlands of north or north-east Bolivia, as the only other Popelairia recorded there is Black-bellied Thorntail P. langsdorffi (in extreme north-west Pando) and three of the other four Popelairia and Discosura species have lowland distributions. However, localities for 19th century trade skins, such as these, are often unreliable, to the extent that the two specimens may not have even come from Bolivia (Graves 1999). Furthermore, international boundaries have changed in this area since the early 19th century, such that parts of the Amazon previously in Bolivia are now in Brazil.
