Skull2 t.png

Alternative name: Letitia's Thorntail

Discosura letitiae

Popelairia letitiae



South America; this species is only known from two specimens taken prior to 1852 labeled Bolivia, but borders have changed and descriptions of location were often unreliable anyway in that period [2]


This is a monotypic species[1].

Discosura vs. Popelairia

Sibley & Monroe (1996) place Wire-crested Thorntail (popelairii), Black-bellied Thorntail (langsdorffi), and Coppery Thorntail (letitiae) in the genus Popelairia. However, Howard & Moore (2003) and Clements (2008) place these three taxa in Discosura, and Opus follows.
