Tetanops myopaeformis, the sugar beet root maggot,[1] is a species of picture-winged fly in the genus Tetanops of the family Ulidiidae.

It is a serious pest of sugarbeets in North America.

The fly was described first by the name Eurycephala myopaeformis by Viktor von Röder in 1881.

[2] In 1907 the name was emended by Friedrich Hendel to Eurycephalomyia in order to avoid confusion with the preoccupied name Eurycephala for a genus of leaf bugs, now called Halticus.
