Chaetonotus (Primochaetus) veronicae n. sp. (Fig. 22, 23) Type locality: Small stream, Abisko Tourist Station, Abisko, Lapland (N 68º 21’ 23’’; E 18º 47’ 59’’), July 3, 2010. Other localities: Kungsleden, Abisko, Lapland (N 68º 21’ 49’’; E 18º 46’ 64’’), July 3, 2010. Type material: Photographs of one specimen, available at the Swedish Museum of Natural History, Stockholm, Sweden. Accession number: Holotype, SMNH Type-8446. Photographs of two specimens, available at the Swedish Museum of Natural History, Stockholm, Sweden. Accession number: Paratypes, SMNH Type-8447 and 8448. Etymology: This species is named in honour of Dr. Veronica Lundgren. Diagnosis: Small species, 123–125 µm in total body length. Body width 25–30 µm, 18 µm, 28–38 µm and 16– 18 µm at head, neck, trunk and base of furca respectively. Head five-lobed with cephalion and weakly developed pleurae. Furca straight, 18–20 µm in length, with thick rigid adhesive tubes. Dorsal body surface covered by round to suboval overlapping scales, anterior parts of which tend to be fused with the body surface. Scales are distributed in 16–19 dorsal columns with 27–30 scales in each. Each dorsal scale carries a simple hair-like strongly curved spine, originating from, and more or less perpendicular to the posterior part of the scale. Ventrolaterally spines are only slightly curved. Ventral interciliary area with small, round to suboval keeled scales, which fuse with the body surface towards the animal’s anterior end. Ventral terminal scales keeled and suboval in shape and strongly overlapping. Seven to eight simple ventral spines can be seen through the caudal incision. Ventral ciliation in two separate longitudinal bands. Mouth subterminal. Pharynx 34–35 µm in length, widens slightly towards the posterior end. Description: Small species, 123–125 µm in total body length (holotype 125 µm in total body length). Head clearly five-lobed with two pairs of cephalic sensory ciliary tufts. Anterior pair with approximately 5 cilia, 5–10 µm in length; posterior pair with ...
