Genus Sapocribrum Lahr et al, 2014
Diagnosis: Amoebae bounded by a continuous thin, somewhat flexible, envelope separated from the plasma membrane and having oval scalelike substructure within a denser matrix; small pores penetrate the envelope, allowing subpseudopodia to protrude for very slow, occasional locomotion; locomotive cells flattened, oval, rounded or irregularly triangular.
Type species: Sapocribrum chincoteaguense n. sp. (Monotypy)
Sapocribrum chincoteaguense Lahr et al, 2014
Diagnosis: Amoeba with characters of the genus, less than 5 µm (more usually 3-4 µm), with typical locomotive angular form that moves infrequently, and when sedentary emits only one to a few long filose pseudopods at a time. Pseudopods may bifurcate. Pseudopods 4.42 0.28 µm, varying from 2.5 to 9 µm. During brief periods of locomotion, the body remains contracted and angular in shape moving in a meandering path in the direction of the extended adhesive pseudopodia, that appear to adhere to the substratum and pull the amoeba forward. Surface contains microscales (~150 X 100 nm in mean length and width, respectively).
Ecology: bottom sediments, marine
