Has been thought probably part of a species-group with A. cuculoides, A. madagascariensis and A. subcristata; in the past, all four sometimes considered conspecific. Five subspecies recognized.

Subspecies and Distribution
  • A. j. ceylonensis (Legge, 1876) – SW India (in S Western Ghats and N Eastern Ghats) and S Sri Lanka#R; perhaps also Andhra Pradesh and elsewhere in E India, but lack of specimens complicates identification of race in this region#R.
  • A. j. jerdoni (Blyth, 1842) – NE India (and presumably this race recorded in S Nepal#R) through Myanmar, S China (SW Yunnan, NW & SW Guangxi#R#R, Hainan), Thailand and parts of Indochina to N Malay Peninsula; some movement S for winter, although recently proven to breed in Sumatra#R.
  • A. j. borneensis (Brüggemann, 1876) – Borneo.
  • A. j. magnirostris (Kaup, 1847) – Philippines.
  • A. j. celebensis (Schlegel, 1873) – Sulawesi, Togian Is#R, Banggai Is and Sula Is.
