Their distributions range from the Indian subcontinent to Southeast Asia.

A 2023 molecular phylogenetic study of the lark family Alaudidae by the Swedish ornithologist Per Alström and collaborators found that the genus Mirafra contained deep internal genetic divergences.

They therefore proposed splitting Mirafra into four genera, each corresponding to a major clade.

Names were available for three of the clades, but for the fourth clade, they introduced the new name Plocealauda and designated the type species as Miafra assamica Horsfield, 1840, the Bengal bush lark.

[2] The genus Plocealauda contains five species, all of which include "bush lark" in their English name.
