Subantarctic rayadito explained

The Subantarctic rayadito (Aphrastura subantarctica) is a species of bird in the family Furnariidae that is endemic to the Diego Ramírez Islands, an archipelago located in the southernmost extreme of Chile.[1]

Taxonomy

Subantarctic rayadito individuals were formerly identified as belonging to the species Aphrastura spinicauda (thorn-tailed rayadito). However, the newly identified A. subantarctica has a larger body mass and shorter tails. In 2022, A. subantarctica was split off as a separate species from A. spinicauda by Ricardo Rozzi et al. (2022), on the basis of genetic, morphological, and behavioral evidence.[2]

The name of the new passerine species Aphrastura subantarctica was made available in the publication “El Rayadito subantártico: disponibilidad del binomio Aphrastura subantarctica (Passeriformes, Furnariidae)”[3] This nomenclatural act has been registered with ZooBank. The LSID for this publication is: urn:lsid:zoobank.org:pub:1EF6362A-A30E-4EA5-8421-950F211EE5D0.

Habitat

While Aphrastura spinicauda lives in forested habitats, A. subantarctica lives in the non-forested habitats of the Diego Ramírez Islands.[4]
