Chlorocharis emiliae

Mount Kinabalu, Borneo

Geographical variation somewhat clinal, from large, long-tailed and dark in N of range to smaller, relatively shorter-tailed and paler in S, but genetic variation among populations suggests existence of two main clades broadly corresponding to subspecific morphological groups (emiliae and trinitae vs moultoni and fusciceps)#R. Four subspecies recognized.

Subspecies and Distribution
  • C. e. emiliae Sharpe, 1888 – Mt Tambuyukon and Mt Kinabalu, in N Borneo.
  • C. e. fusciceps Mees, 1954 – Maga Mts (S part of Crocker Range), in N Borneo.
  • C. e. trinitae Harrisson, 1957 – Mt Trus Madi, in N Borneo.
  • C. e. moultoni Chasen & Kloss, 1927 – mountains of N & W Borneo: Mulu, Murud, Tama Abu Range and Poi (Pueh) Range (in Sarawak) and Mt Niyut (in W Kalimantan).
