Description of the family Padaungiellidae and morphological variability of Padaungiella lageniformis (Amoebozoides: Arcellinida) from the Vlasina Lake area, Serbia
Based on theoretical conclusions, a new family of testate amoebae, Padaungiellidae, is described. It includes three genera: Alocodera, Apodera and Padaungiella. The most striking characteristic of the members of this family is an elongated neck, and absence of sets of teeth and septa along...

| Summary: | Based on theoretical conclusions, a new family of testate amoebae,
Padaungiellidae, is described. It includes three genera: Alocodera, Apodera
and Padaungiella. The most striking characteristic of the members of this
family is an elongated neck, and absence of sets of teeth and septa along the
oral-aboral axis on the inner side of the neck. The most common species of
this family is Padaungiella lageniformis. Morphometrically, this species is
not analyzed yet, so the qualitative and quantitative characters of a
sphagnicolous population of P. lageniformis from the Vlasina Lake area
(Serbia) are reported here. Quantitative characters were analyzed by
univariate statistical methods. Coefficients of variation were moderately low
for all the measured characters (range from 4.37 to 10.71%). Frequency
distribution of only seven of sixteen variables showed approximately zero
level of kurtosis, which indicated that specimens with average measurements
were not predominant in the studied population. This paper provides evidence
of the presence of an aberrant form of P. lageniformis. |
