Parectopa bumeliella is a moth of the Gracillariidae family. It is known from Kentucky and Arkansas, U.S.A. It was described by A.F. Braun in 1939. The hostplants for the species include Sideroxylon lanuginosum and Sideroxylon lycioides. They mine the leaves of their host plant. The mine has the form of a wide upperside linear mine expanding into a white blotch, usually obliterating the early mine. The blotch is roughly oval in outline.
