Labyrinthomyxa ; a possibly unrelated net-forming protist

A heterotrophic net-forming protist superficially similar to labyrinthulids is Labyrinthomyxa ( Dubosq 1921) with an anteriorly directed single cilium and a single amoeba phase; as its spindles do not move within the net, which in some respects is more like that of Leukarachnion (Grant et al. 2009), and there is no evidence for a laminate (or other) theca we exclude it from Labyrinthulea and establish a separate family (Labyrinthomyxidae), here placed incertae sedis in Harosa as it is unclear whether it belongs in Heterokonta (possibly Leukarachnida; unlike Leukarachnion not known to be phagotrophic) or Cercozoa (possibly Endomyxa).
