Formerly known as C. malayanus, but type of that name is, in fact, a female Chrysococcyx xanthorhynchus. C. minutillus (sensu stricto) considered to be most closely related to C. meyerii#R. Internal taxonomy of present species confused; has been considered to constitute five species#R, a treatment fairly widely followed#R#R#R, but songs of all forms, where known, are apparently identical. While forms listed are generally allopatric, and all use the same type of host species, the apparent occurrence of two forms (cleis, aheneus) in Borneo suggests possible separate species status: poecilurus group (aheneus, jungei, poecilurus, misoriensis, russatus and undescribed race from Timor) sometimes treated as a species distinct from minutillus group (peninsularis, albifrons, cleis, minutillus and barnardi) owing to apparent sympatry without interbreeding in Borneo, but this may involve migrant birds, and representatives of both groups (russatus and barnardi) interbreed extensively in N Australia. Moreover, the geographical breakdown of these “species” is improbable (e.g. birds of minutillus group in N Borneo, all the Moluccas and W Lesser Sundas; birds of poecilurus group in Philippines, Sulawesi, Flores and New Guinea). Form rufomerus often treated as a separate species, but reported as intergrading with minutillus on five of its six known islands#R, which would seem to render the specific separation of the taxon unworkable. Form crassirostris often treated as conspecific with C. minutillus, but here split off as a separate species with race salvadorii (see below). In addition, in Borneo, cleis (described from NE Kalimantan) appears to split the range of aheneus (described from S Kalimantan, but with range in SE Borneo and S Philippines); cleis is, therefore, sometimes synonymized with aheneus#R#R. The species composition and relationships of this entire group of taxa, including C. crassirostris, are still under revision#R; in a recent molecular study, barnardi found to be genetically the most distinct taxon#R. Eleven subspecies currently recognized.

Subspecies and Distribution
  • C. m. peninsularis (S. A. Parker, 1981) – extreme S Indochina, S Thailand and Peninsular Malaysia.
  • C. m. albifrons Junge, 1938 – Sumatra and W Java.
  • C. m. cleis (S. A. Parker, 1981) – N & E Borneo.
  • C. m. minutillus (Gould, 1859) – Little Bronze-cuckoo – Moluccas, W Lesser Sundas and N Australia, from Kimberley district of NW Australia through Melville I and Arnhem Land to N Queensland (Gulf of Carpentaria to W Cape York).
  • C. m. barnardi (Mathews, 1912) – E Australia (SE Queensland to NE New South Wales).

  • C. m. jungei Stresemann, 1938 – Sulawesi, Madu (S of Sulawesi) and WC Lesser Sundas (Flores).
  • C. m. poecilurus (G. R. Gray, 1862) – Gould's Bronze-cuckoo – lowlands on N & S coasts of New Guinea, and offshore islands, including W Papuan Is (Misool).
  • C. m. misoriensis (Salvadori, 1876) – Biak I (Geelvink Bay).
  • C. m. russatus (Gould, 1868) – N & E Queensland (Cape York S along E coast).
  • Also present on Timor, where an apparently distinctive race, as yet undescribed, occurs.
