Malkoha
Malkohas are large birds in the cuckoo family Cuculidae, all in the genus Phaenicophaeus. The group name is derived from the Sinhala word for the red-faced malkoha; mal-koha meaning flower-cuckoo. These are all Asian tropical species. The genus name is derived from the Ancient Greek phoiniko- crimson, and phaes "eyes" or "face", referring to the red-faced malkoha. However, the 'œ' was mistranscribed as 'æ'.

Raffles's malkoha is a highly distinct species and may not even be as closely related to malkohas as long believed. Its placement in a monotypic genus Rhinortha is supported by a morphological, molecular and behavioral evidence.
The green malkoha or yellowbill seems also distinct from the typical malkohas; it is placed in the monotypic genus Ceuthmochares.
