Abstract: | The morphology of poorly known freshwater amoebae, Saccamoeba wellneri Siemensma, 1987 and Saccamoeba limna Bovee, 1972, were investigated using living observations at light microscopic level. S. wellneri was collected from Karloveské rameno branch of the Danube River and Štrkovecké jazero lake in Bratislava, Slovakia. Its locomotive
form is typical with crescent-shaped and bipyramidal crystals and uroid with short wart-like papillae. S. limna was found in an indoor freshwater aquarium in Bratislava, Slovakia. The locomotive form of S. limna has broad monopodial shape and possesses typical hyaline uroid with short nonadhesive filaments. Many small bipyramidal crystals
were noted. Additional data and details on the morphology of both species were described and illustrated and re-diagnoses
are presented. This paper is helpful for their identification on the base of locomotive morphology, floating, and resting
forms and allows distinguishing S. wellneri and S. limna from other hartmannellids at light microscopic level. |
