Agnidra fuscilinea is a moth in the Drepanidae family. It was described by Watson in 1961. It is found on Peninsular Malaysia, Sumatra and Borneo. The wingspan is 20.5-21 mm for males and 19.5-21 mm for females. It is easily separable from related Agnidra scabiosa by the colour-pattern of the wings. Externally, fuscilinea is closest to Agnidra vinacea, from which it differs by the dark-edged patches on the wings.
