On the sympatric occurrence of two subspecies of Blue-crowned Manakin, Lepidothrix coronata exquisita and L. c. caelestipileata, in south-west Amazonia

Abstract

I present evidence of sympatric occurrence of two subspecies of Blue-crowned Manakin Lepidothrix coronata in south-west Amazonia. Specimens collected in eastern Acre in Brazil and northern Bolivia, as well as records from south-east Peru, indicate that L. c. exquisita and L c. caelestipileata both occur in the south-east of the Inambari centre of endemism, when compared to their respective holotypes. Thus, L. c. exquisita, which was considered endemic to central-north Peru, is also present in the lowlands of south-west Brazilian Amazonia and northern Bolivia, whilst caelestipileata, previously known from the Juruá–Madeira region in Brazil, is present further south, reaching south-east Peru and northern Bolivia.
