Description
Summary:Chaetonotus (Primochaetus) veronicae Kånneby, 2013 (Figs. 1, 2; Table 1; Kånneby 2013: Fig. 22) Type locality. Small stream, Abisko Tourist Station, Abisko, Lapland (N 68º 21’ 23’’; E 18º 47’ 59’’), July 3, 2010. Other localities. Snasahögarna, Jämtland (N 63º 12’ 39’’; E 12º 18’ 19’’), July 7, 2008; 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. Other material. Photographs of one specimen. Etymology. This species is named in honour of Dr. Veronica Lundgren. Diagnosis. Small to medium-sized Chaetonotus , 123–135 µm in total body length. Body width 25–30 μm, 18–24 μm, 28–38 μm and 15– 18 μm at head, neck, trunk and base of furca, respectively. Head five-lobed with two pairs of sensory ciliary tufts. Cephalion and pleurae present. Furca straight, 18–20 μm in length, with thick, rather stumpy, 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 17–20 dorsal columns with 27–30 scales in each. Dorsal scales bear rather thin, almost hair-like, deeply bifurcated spines. The proximal part of each spine, gives a dotted appearance of the dorsal surface at specific optical sections; the distal bifurcation comes at an angle, varying between close to 90 degrees and 150 degrees. Each spine of the bifurcation is simple, e.g. not dentate. 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 overlapping. Seven to eight simple ventral spines can be seen through the caudal incision. Ventral ciliation in two separate longitudinal ...
