This flycatcher is about 13 centimetres (5.1 in) long and has a longish beak. It forages in the undergrowth in the shade of dense forest canopy where it makes aerial forays to capture insects. The male is indigo blue with ultramarine blue supercilium and forehad. The lores and face are dark grey. The belly is white and bordered by smoky grey wash. The female is olive brown above with whitish lores. The rufous throat and breast fades to white towards the belly. The female has a chestnut tail and can be told apart from other flycatchers like by the lack of the black and white tail pattern.
