A new species of fish leech from England, Piscicola siddalli n. sp. (Piscicolidae), was collected in 2006 on stones and on grayling (Thymmallus thymmallus L.) in the River Ure, North Yorkshire, Great Britain. The leech is 4(12) annulate; gonopores are separated by four annuli. The male gonopore is much larger than the female gonopore. Seminal receptacle consists of a round aperture, located at a distance of 3 annuli behind the female gonopore. Copulatory area on the clitellum is in the form of a circle. Vector tissue has the form of a circular plate, below the oviduct opening.
