We list 61 species representing 13 genera within 4 families and 2 orders of aspidogastreans associated with 298 species of invertebrate and vertebrate hosts. The majority of records include bivalves (44% of the total number of host-parasite associations), whereas records from bony fishes represent 32% of host-parasite associations. The aspidogastreans have worldwide distribution, with the highest number of records in the Neartic Region for freshwater hosts and the North Atlantic Ocean for marine ones. The checklist includes a parasite-host list with data on host habitat, site of infection and distribution area of parasites, and a host-parasite list. A limited number of molecular studies on aspidogastreans does not allow us to unravel phyloge- netic relationships within the Aspidogastrea. Key words: Biodiversity, Taxonomy, Aspidogastridae, Multicalycidae, Rugogastridae, Stichocotylidae Introduction Aspidogastrean trematodes are a small group of parasitic flatworms (Neodermata) with worldwide distribution, characterized by having a ventral holdfast organ with rows of alveoli or suckerlets, or just presenting a row of rugae or suckers (Rohde 2005). Aspidogastreans parasitize molluscs as obligate hosts and vertebrates (fishes and turtles) as facultative or obligate final hosts (Rohde 2002); they represent the most basal group of trematodes (Trematoda) (Olson et al. 2003). The first described species of aspidogastrideans was Aspidogaster conchicola von Baer, 1826 recovered from the pericardial cavity of unionid mussels of the genera Anodonta Lamarck and Unio Retzius in Prussia, a historical region of Germany (currently part of Poland and the Kaliningrad Region of Russia). Since then, several attempts have been made to classify these trematodes that possess a peculiar ventral attachment apparatus. In a first attempt to classify the Trematoda, Burmeister (1856) suggested the division of them into three groups (Pectobothrii, Malacobothrii and Aspidobothrii); the last one was proposed to accommodate the genus Aspidogaster von Baer. However, some authors (Cunningham 1884, 1887) considered the group to belong to polystomids (currently a subclass of the Monogenea) or used the name Aspidobothrea Monticelli for this group. Thereafter, several new genera and species were erected (Leidy 1857; Olsson 1869; Cunningham 1884). A new classification was proposed by Monticelli (1892) based on a critical review of Burmeister’s (1856) classification, with the suborder Aspidocotylea Monticelli replacing the former terms for aspidogastreans, including the single family Aspidobothridae Monticelli. The etymology of Aspidocotylea is stemming from inclusion of Aspidocotylus Diesing into the group. However, this genus clearly does not belong to aspidogastreans and it was excluded by several authors (Faust & Tang 1936; Dollfus 1956, 1958a; Yamaguti 1963; Rohde 1972). At present, it is considered to be a digenean genus incertae sedis within the Paramphistomoidea (Jones 2005). Accepted by N. Dronen: 19 Dec. 2014; published: 12 Feb. 2015 339 within them (Littlewood 2006). More robusts analyses based on morphological and molecular data (including multigenes) are necessary to clarify the relationships within Aspidogastrea and thus to improve our knowledge on the evolution of both aspidogastrean and digenetic trematodes.

Pomeranian Bay as an ecotone is a transition zone between two different biocenoses, which is characterized by an increase in biodiversity and species density. Therefore, Pomeranian Bay is a destination of finding and reproductive migrations of fish from the rivers entered the area. The aim of the study was to compare parasitic fauna of two predatory fish species from the Pomeranian Bay, collected from the same fishing grounds at the same period. A total of 126 fish studied (53 perches and 73 zanders) were collected in the summer 2013. Parasitological examinations included: skin, fins, gills, vitreous humour and lens of the eye, mouth cavity, body cavity and internal organs. Apart from the prevalence and intensity of infection (mean, range) the parasite communities of both fish species were compared. European perch and zander were infected with parasites from five different taxonomic units. The most numerous parasites were Diplostomum spp. in European perch and Bucephalus polymorphus in zander. The prevalence of infection of European perch ranged from 5.7% ( Diphyllobothrium latum ) to 22.3% ( Diplostomum spp.) and for zander from 1.4% ( Ancyrocephalus paradoxus , Hysterothylacium aduncum ) to 12.3% ( Bucephalus polymorphus ).

The parasitic fauna included two myzozoans, one choanozoan, seven ciliophorans, 24 myxozoans, eight trematodes, 34 monogeneans, 12 cestodes, 11 nematodes, five acanthocephalans, two annelids and nine crustaceans. The infection with some trematodes and nematodes occurred with larval stages, while the remaining infections were either with trophozoites or adult parasites. Among the inspected fishes, Cyprinion macrostomum was infected with the highest number of parasite species (29 parasite species), followed by Carasobarbus luteus (26 species) and Arabibarbus grypus (22 species) while six fish species (Alburnus caeruleus, A. sellal, Barbus lacerta, Cyprinion kais, Hemigrammocapoeta elegans and Mastacembelus mastacembelus) were infected with only one parasite species each. The myxozoan Myxobolus oviformis was the commonest parasite species as it was reported from 10 fish species, followed by both the myxozoan M. pfeifferi and the trematode Ascocotyle coleostoma which were reported from eight fish host species each and then by both the cestode Schyzocotyle acheilognathi and the nematode Contracaecum sp.

Wien 106 B 141-144 Wien, Juli 2005 Aspidogaster limacoides DIESING, 1835 (Trematoda, Aspidogastridae): A new parasite of Barbus barbus (L.) (Pisces, Cyprinidae) in Austria Schludermann C.*, Laimgruber S., Konecny R., Schabuss M. Abstract Adults of the trematode parasite Aspidogaster limacoides DiEsrNG, 1835 were found in the cyprinid Bar- bus barbus (L.) during a parasitological investigation of endohelminths in the years 2001 and 2002 in the Danube downstream of Vienna, Austria. This is the first record of A. limacoides in barbel from the Austrian part of the Danube system. Zusammenfassung Adulte Formen des Trematoden Aspidogaster limacoides DiEsrNG, 1835 wurden in einer Population der Barbe Barbus barbus (L.) in der Donau flussab von Wien gefunden. Die Erfassung erfolgte im Rahmen einer fischparasitologischen Aufnahme in den Jahren 2001 und 2002. Es ist der erste gesicherte Fund von A. limacoides in der Barbe im österreichischen Teil der Donau. Keywords: Aspidogaster limacoides, Barbus barbus, Trematoda, Austria, Danube Introduction The subclass of Aspidogastrea (FAUST & TANG, 1936) consists of a small group of trematodes with a worldwide distribution comprising about 80 species and has not been described for Austria yet. The Aspidogastrea parasitise poikilothermous animals like crustaceans, molluscs, fish, and reptiles in marine and freshwater environments. In contrast to their sister group, the digenean trematodes, they present simple life cycles with no multiplicative larval stages. Aspidogaster limacoides DiEsrNG, 1835 was found in molluscs and fish from river basins in the Ponto-Caspian region (e.g. BYKHOVSKAYA- PAVLOWSKAYA & al, 1962, EVLANOV 1990, NAGIBINA & TIMOVEEVA 1971). The hosts involved consist of mollusc and a definitive or facultative vertebrate host, nevertheless most aspidogastrids require only a single host to complete their life cycle (RHODE 1972).
