N2 - We studied a large species of Thecamoeba found in a glass dish with soaked moss and obtained 18s rRNA gene sequence of this organism. Morphologically, the strain was most similar to T. terricola sensu Page, but had significant differences in cell size and nuclear morphology. A more complete similarity was found with the original description of “Amoeba terricola” by Greeff, as well as with Penard's descriptions and slides. The analysis of literature data shows that the strain described by Page in 1977 as a re-isolated T. terricola differs from the original description of this species provided by Greeff in 1866 and data by Penard published in 1902 and 1913. Based on our observations as well as on Greeff's and Penard's data, we reassessed the species boundaries of T. terricola and established T. vicaria n. sp. for the organism described by Page in 1977. The species T. terricola was defined according to its original description. The observations of amoebae on agar have shown that T. terricola cells can form the “standing amoeba” stage, previously described only for Sappinia pedata. This and some other “behaviour” features of T. terricola may be associated with living conditions in terrestrial habitats.
