Polychaos is an amoeboid genus in the Amoebozoa group.[2] Several characters unite the species in this genus. The pseudopods meld at their bases when the organism is moving, and have dorsal, longitudinal ridges. The nucleus is oval or ellipsoidal.[3]

Classification

Polychaos includes the following species:[3]

  • Polychaos annulatum (Pénard 1902) Smirnov & Goodkov 1998
  • Polychaos dubium (Schaeffer, 1916) Schaeffer 1926
  • Polychaos fasciculatum (Penard, 1902) Schaeffer 1926
  • Polychaos nitidubium Bovee, 1970
  • Polychaos timidum Bovee, 1972

Phylogenetic analysis has shown this that genus belongs to the family Hartmannellidae.[4]
