Psittrichasiidae
Psittrichasiidae is a family of birds belonging to the superfamily of the true parrots (Psittacoidea). It is a very small family, the smallest of the three families of the true parrots. It is divided into two subfamilies: Psittrichasinae and Coracopsinae, that contain a single genus each. The first contains a single species, native to New Guinea, and the second contains four living species distributed throughout Madagascar and other islands of the Indian Ocean. Genera
The family Psittrichasiidae contains two subfamilies:

Subfamily Psittrichasinae:
 Genus Psittrichas
 Psittrichas fulgidus - Pesquet's parrot

Subfamily Coracopsinae
 Genus Coracopsis
 Coracopsis barklyi - Seychelles black parrot
 Coracopsis nigra - Lesser vasa parrot
 Coracopsis vasa - Greater vasa parrot
 Coracopsis sibilans - Comoros black parrot (split from Coracopsis nigra)

Recent studies indicate that the extinct Mascarene parrot (Mascarinus mascarinus) was closely related to the members of Coracopsis. References
