Vulva with lateral vulval membranes, um long or about 3 annules wide; vagina slightly inclined anteriorly with thickened walls; postuterine sac short; spermatheca empty. Distance from vulva to anus 91 um. Tail damaged, but annules up to finely rounded terminus. Remarks. Although the tail of this specimen is damaged, it is clearly different from the other species of Coslenchus found in Loch Ness. Ratios effected by this damage are considered to be close to measurements that would have been obtained had the specimen been undamaged. It keys out close to C. pastor Andrassy, 1982, but the morphometries are a poor fit. Filenchus cf. discrepans (Andrassy, 1954) Raski & Geraert, 1987 (Fig. 6) Material examined.
