Iole is a genus of songbirds in the bulbul family, Pycnonotidae. They are native to tropical eastern Asia, from India to China and south through Southeast Asia to northern Indonesia.

Taxonomy

The genus Iole was introduced in 1844 by the English zoologist Edward Blyth to accommodate a single species, Iole olivacea Blyth, 1844. This is the type species of the genus.[1] This species was moved to the genus Hypsipetes, together with Hypsipetes olivaceus that had been introduced in 1837 by the English naturalists William Jardine and Prideaux John Selby.[2][3] Under the rules of the International Commission on Zoological Nomenclature (ICZN), Iole olivacea Blyth, 1844 became a junior secondary homonym and is therefore permanently invalid, even now that the taxa are no longer considered congenic.[4] The name Iole olivacea Blyth, 1844 has been replaced by Iole olivacea crypta Oberholser, 1918, which is now treated as a full species, the buff-vented bulbul.[5][6]

Although this genus was formerly merged into Hypsipetes,[7] molecular phylogenetic analyses indicate that these two lineages are not each other's closest relative.[8][9]

Species

The genus contains the following seven species:[10]

Image Common name Scientific name Distribution
- Finsch's bulbul Iole finschii Malesia
Sulphur-bellied bulbul Iole palawanensis Palawan
- Olive bulbul Iole viridescens Northeast India and western Indochina
Buff-vented bulbul Iole crypta Thailand, Malay peninsula and Sumatra
Charlotte's bulbul Iole charlottae Borneo
- Cachar bulbul Iole cacharensis Northeast India and Bangladesh
Grey-eyed bulbul Iole propinqua Indochina and adjacent southern China

Former species

Formerly, some authorities also considered the following species (or subspecies) as species within the genus Iole:
