Imbricatea

Paulinella is a genus of amoeboid protists with at least twelve species of freshwater and marine euglyphids. Like many other euglyphids, it is covered by rows of siliceous scales, and use filose pseudopods to crawl over the substrate of the benthic zone. Species within the group can be distinguished by features like the overall shell dimensions, the number of vertical scale rows (3–5), the number of scales per row (7–14) and the number of oral scales.

The euglyphids are a prominent group of filose amoebae that produce shells or tests that in most described species is reinforced by siliceous scales, plates, and sometimes spines, but this reinforcement is absent in other species.

Euglypha is a genus of cercozoans. It includes the species Euglypha rotunda.

Imbricatea is a class of Rhizaria characterised by silica scales. It is sometimes described as "Imbricatea/Silicofilosea", due to the similarity of those two groupings. Imbricatea is divided into the orders Euglyphida and Thaumatomonadida.

Trinema is a genus of testate amoeba in the phylum Cercozoa. It includes the species Trinema lineare. Species of Trinema are common in freshwater and terrestrial habitats.

Thaumatomonadida is an order of flagellates.
