Description
Haltidytes crassus (Greuter, 1917)
(Figure 17)
Localities. Artificial pond, Nybro, Småland (N 56º 44’ 89’’; E 15º 54’ 27’’).
Material. 4 specimens. TL, 97–130 µm; PhL, 35–40 µm; DSL, 100–120 µm; VSL, 120–162 µm.
This species is characterized by three pairs of ventral spines; the posterior pair is the longest. Dorsally five pairs of spines are present; the anterior three pairs originate ventrolaterally while the posterior two pairs originate from the ventral side. Interciliary area naked. Locomotory ciliation in two longitudinal bands, each band further divided into tufts, and three semi-circular bands on the head. The Swedish specimens correspond well to the specimens found in Poland (Kisielewski, 1981) and Denmark (Grilli et al., 2010).
