Ketupa is a genus of owls in the family Strigidae. The genus formerly contained just three species, the fish owls but based on the results from a genetic study published in 2020, the generic boundaries were altered. The genus now contains twelve species, nine of which were formerly placed in the genus Bubo.
This genus formerly contained fewer species. A molecular phylogenetic study of the typical owl family (Strigidae) published in 2020 and another study published in 2021 found that the genera Ketupa and Scotopelia were embedded in the genus Bubo, rendering the genus paraphyletic. In a move to create monophyletic genera, nine species were moved from Bubo to Ketupa. Four of these species (shelleyi, coromandus, leucosticta, and philippinensis) had not been sampled in the genetic studies but were assumed to belong to Ketupa based on their morphological similarities to those species that had been sampled. Scotopelia (containing the fishing owls) was retained as a separate genus, although the genetic results suggested that the Scotopelia may be embedded within Ketupa.[5][6][7]
