Leiothrix Leiothrichidae Ancient Greek leios meaning "smooth" and thrix meaning "hair".
The name Actinodura is derived from Greek words meaning "ray-like tail" (actinodes and ura).
The epithet sodangorum came from the Sodang tribe (also known as Xo Dang) which lives in Ngoc Linh and other areas in Vietnam, Cambodia and Laos where black-crowned barwings are distributed.
