Cheliplana evdonini Karling, 1983

Material examined. None.

Known distribution. Tekslo Island, Hordaland Fylke, Norway ( Karling 1983).

Remarks (summarised from literature). The long prepharyngeal cavity is armed with spines. The proboscis bears a pair of 16-µm-long hooks.A pair of soft, terminally enlarged, rod-shaped sidepieces is present. Each sidepiece bears a single, long bristle. A single testis is situated alongside the pharynx and a single vas deferens connects the testis to an unpaired seminal vesicle, which has an elongated, winding shape. The copulatory bulb is ~60 μm long and 30 μm wide. Proximally, it contains a globular prostatic vesicle, which empties distally into the armed cirrus. Three parts can be distinguished on the cirrus: (1) a short, proximal, tubular part, ~20 μm long and armed with very small, hair-like spines; (2) a girdle with five hooks, each ~13 μm long; (3) a wider, distal, tube-like part, measuring ~23 μm and armed with fine hooks of ~4–8 μm.

The bursa lies adjacent to the distal part of the cirrus. The vitellarium stretches out from the posterior end of the pharynx to the ovary. Karling (1983) mentions the excretory system, which is remarkably conspicuous compared to other schizorhynchs: he observed two lateral canals, which are interconnected through a transverse canal, located mid-body.
