Table 1 in Morphological Redescription and SSU rDNA-based Phylogeny of Two Freshwater Ciliates, Uronema nigricans and Lembadion lucens (Ciliophora, Oligohymenophorea), with Discussion on the Taxonomic Status of Uronemita sinensis

Table 1. Morphometric data of Uronema nigricans (Müller, 1786) Florentin, 1901 (upper line) and Lembadion lucens (Maskell, 1887) Kahl, 1931 (lower line) from life and after protargol staining. Some specific characters of these two species are shown separately.
