This drongo is treated as endemic to Tablas Island in the Philippines. Its outer tail feathers are very long and curve outward at the tips; most field observations were in mature, closed-canopy forest.
Adults have very long outer tail feathers that curve widely outward; some tips curl upward like a partial helix. The body is blackish and velvety, with a purple or green sheen in good light. Breast spangles are few and small, and the neck hackles are short.
On Tablas, pairs and family parties of two to four were seen in mature closed-canopy forest. Birds foraged in vine tangles, sometimes holding dead leaves with one foot while picking insects from them with the bill. They were mostly quiet during the visits, with occasional rasping calls.
