Taxonomy and systematics

This species was formerly considered a conspecific member of the little shrikethrush complex. Genetic investigations of New Guinea populations of the little shrikethrush indicate high levels of genetic divergence, suggesting it comprised more than one species.[1]

Subspecies

Currently, three subspecies are recognized:[2]

  • C. m. megarhyncha - (Quoy & Gaimard, 1832): Found on Salawati and Misool (off northwestern New Guinea), Aru Islands (off southwestern New Guinea) and New Guinea
  • C. m. parvula - Gould, 1845: Originally described as a separate species. Found in north-eastern Western Australia and northern Northern Territory (Australia)
  • C. m. aruensis - (Gray, GR, 1858):Aru Islands, Trans-Fly region of south New Guinea

It is found in New Guinea and Australia. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests.
