A new species of fish leech from Poland, Piscicola burresoni n. sp. (Piscicolidae), is described. The leech was found in 2007 on stones and on pike ( Esox lucius L.) and chub ( Leuciscus cephalus L.) in the Łyna River, Poland. The leech is small, relatively flattened, with a prominent coarctation between the trachelosome and urosome. The pigmentation is unique to the new species and it has 14 annuli with gonopores separated by 4 annuli. The receptaculum seminis consists of an elliptical aperture located at a distance of 3 annuli behind the female gonopore. The copulatory area on the clitellum is characteristic in the shape of a parallel ellipse. The vector tissue is in the form of a transverse plate below the oviduct outlet. For a complete description of the external morphology, a geometric-mathematical model of the leech body form was used.
描述了一种来自波兰的新种鱼蛭，即伯勒索尼鱼蛭（Piscicola burresoni n. sp.）（鱼蛭科）。该水蛭于2007年在波兰利纳河的石头上以及梭子鱼（白斑狗鱼，Esox lucius L.）和雅罗鱼（赤睛鱼，Leuciscus cephalus L.）身上被发现。这种水蛭体型小，相对扁平，在颈体与尾体之间有明显的缢缩。色素沉着是该新物种所特有的，它有14个环带，生殖孔相隔4个环带。贮精囊由位于雌孔后方3个环带处的椭圆形孔口组成。环带区的交配区域呈平行椭圆形状，具有特征性。载体组织呈输卵管出口下方的横向板状。为完整描述外部形态，使用了水蛭身体形态的几何数学模型。
