Genus Dracoamoeba Tice & Brown 2016
Diagnosis: amoebae with ramose pseudopodia with the ability to form lamellapodium with acanthapodial subpseudopodia. Pseudopods of all forms made up of hyaloplasm and used for locomotion and feeding. Cell body made of granuloplasm.
Type species: Dracoamoeba jomungandri n. sp.
Dracoamoeba jomungandri Tice & Brown 2016
Diagnosis: Characteristics of the genus. When attached to the surface of a culture flask amoebae exhibit long, tapering thin ramose pseudopodia from all sides of the main cell body. Amoebae in this state range from 33 μm – 87 μm (mean = 57.6 μm, standard deviation = 15.6 μm, n = 34) long. The width of the cell body ranges from 3 μm- 12 μm (mean = 6.2 μm, standard deviation = 2.4 μm, n = 34). Psuedopodia are composed of hyaloplasm while the main body of the cell is granuloplasmic in nature. Amoebae do not form uroids. No cysts have been observed. Upon starvation amoebae will shrivel up and detach from the surface. These amoebae will remain suspended in the water column or float on the surface of the water.
Type habitat: Moist soil from mud flat approximately 800 yards from the ocean, Chincoteague, VA.
Type material: Type culture deposited with the American Type Culture Collection as Stereomyxa ramosa. Accession number 50982.
