Truly tiny flycatcher with a large-headed, large-eyed, stub-tailed appearance. Inhabits shady forests and bamboo at upper elevations (1000-2000 m). Male blue above with short white supercilium and bright orange throat that fades towards the belly. Female brown above with rufous-tinged wings, pale eyering, and structure unlike any other species. Forages lower than most other flycatchers, sometimes even on the ground. The subspecies on Taiwan (innexa) is endemic.
