Acinetactis is a possible genus of protist first described in 1886 by A.C. Stokes, who also described the type species A. mirabilis.^[1] In 1928, Valkanov reported the discovery of a second species, A. arnaudovii.^[2] The most recently recorded specimen of A. mirabilis was reported in 1940, no Acinetactis specimens have been reported since.^[3]

The validity and classification of this genus is contested. In 1914, Adolf Pascher cast doubt on Acinetactis, suggesting that it was a junior synonym of Dimorpha mutans.^[4] Cavalier-Smith classified Acinetactis as a heliomonad in 1993.^[5] Bass et al. suggested in 2009 that the genus was a cercozoan in the class Granofilosea.^[6]
