Abstract Trematodes are parasitic flatworms, mainly have complex life cycles involving multiple hosts, including mollusks, fish, vertebrates and occasionally invertebrates. Adult trema­todes have a big morphological diversity and examination of the morphological structures is important for species identification. Currently not all available tools for examination of parasite’s morphology used for in depth characterization of trematode structure. Here, the authors suggest benzanthrone luminophore 3-N-pyrrolidinylbenzanthrone for fast and high-resolution imaging of morphological structures using confocal laser scanning microscopy. In this study we focused on the amphibian parasite of Prosotocus genus. Many species of amphibians worldwide are facing decline and have been often associated with disease. Trematode infections of amphibians can cause numerous disorders, such as grotesque limb malformations, kidney damage and debility. Applying an efficient tech­nique for species identification and examination of morphological structures allows us to deepen understanding of co-infections, multiparasitism, host-parasite relationships, and biodiversity protection. Keywords: Prosotocus confusus, trematode, morphological data, CLSM; benzanthrone dye. *Corresponding author: Muza Kirjusina.
