The record of the North-American gastropod Menetus dilatatus in the Southern Bohemia is mentioned in this paper. This finding is more than 80 km distant from known localities in the Elbe River Lowland and is the first one in the Southern Bohemia. This species was found in the mapping field for faunistic grid mapping No. 6551 (see Fig. 1) in the Otava River in the Orlík Dam Lake by diving in the water depth of ca. 2 m.

Menetus dilatatus (Gould, 1841) has been found in July 2005 in the Lipno Reservoir (Bohemian Forest = Šumava Mts., Southern Bohemia, Czech Republic) at 12 particular sites. This locality is about 80 km south of the nearest known locality of Menetus dilatatus and more than 160 km south of the Elbe Lowland where Menetus dilatatus occurs in many sites including the Elbe River. The altitude of the Lipno Reservoir reaches 725 m a.s.l. and is the highest known altitude of Menetus dilatatus in the Czech Republic.

AbstractGyrodactylid parasites were observed on non-native populations of North-American freshwater catfishes, Ameiurus nebulosus and Ameiurus melas (Siluriformes: Ictaluridae), at several sites in the Elbe River basin, Czech Republic, Europe. Using a combination of morphological and genetic analyses, the parasites infecting A. nebulosus were determined to be Gyrodactylus nebulosus, a North American parasite co-introduced to Europe along with its Ameiurus fish hosts. Subtle morphometrical differences, as well as seasonal variations, were observed among parasites collected from A. nebulosus and A. melas. The host-related variation was further supported through genetic analysis of the partial 18S rDNA, ITS1-5.8S-ITS2 and COI, showing 0.2, 3.0 and 4.8% divergence, respectively. Consistent genetic differences indicated there were two distinct genotypes. Subtle morphological differences associated with the shape of sickle toe, anchor root and ventral bar membrane, according to host species, also supported the description of a new cryptic species, Gyrodactylus melas n. sp., infecting A. melas. Multivariate morphometrical analysis of haptoral hard parts showed significant differences between the anchor lengths of G. nebulosus and G. melas n. sp. However, the measurements of the haptoral hard structures partially overlapped between species, limiting the usage of these parameters for species delineation.

First Time

The polypore Trametes gibbosa (Pers.) Fries, common in Europe and Asia, is reported from eastern North America for the first time. Single basidiospore cultures from Pennsylvania, United States, and Quebec, Canada, were paired with each other and with cultures from the Czech Republic. The North American intercollection crosses were 60% compatible and 100% compatible with the Czech cultures. All the crosses among the Czech cultures were 100% compatible. The recent introduction of T. gibbosa to North America is suggested as a possible explanation for the limited number of mating-type alleles and subsequent incompatibility among the North American cultures.
