New gymnamoebae species (Gymnamoebia) in the fauna of Ukraine

Lobose gymnamoebae (representatives of the subclass Gymnamoebia Haeckel, 1862, class Lobosea
Carpenter, 1861) inhabit almost all water and soil biotopes. However, because of difficulties in the species
identification, fauna of these protists in many areas, including Ukraine, is almost unstudied till now. In a few
papers from XIX—XX centuries there are scant fragmentary data on gymnamoebae found in this region
(Stepanov, 1885; Vysotskiy, 1885; Pereyaslavtseva, 1886; Butchinskiy, 1897; Dobrovlyanskiy, 1914;
Krasheninnikov, 1925; Fadeev, 1929). The works of M. P. Bozhko (1936, 1937) on soil gymnamoebae with
19 recorded species of these protists also worth to be mentioned (cited by Lepinis et al., 1973). In our previous
studies we found 10 species of gymnamoebae (Patsuyk, 2010). In general, only 22 species are mentioned
for Ukraine in literature. It is absolutely clear that representatives of the subclass Gymnamoebia need
special comprehensive study using the up-to-date research methods applied for amoeboid organisms.
