Abstract

Morphological and metrical analyses of monogeneans from the gills of Antarctic rockcod Notothenia coriiceps revealed the presence of a new species, Pseudobenedeniella johnstoni sp. n. Fresh specimens of monogeneans collected from N. coriiceps from the vicinity of Galindez Island, Argentine Islands, West Antarctica were examined morphologically, by molecular analysis and Energy Dispersive X-ray analysis (EDXA). The new species differs from Pseudobenedeniella branchialis Timofeeva, Gaevskaya, Kovaljova, 1987 by the different shapes of anterior and posterior hamuli, the presence of a pronounced sickle-shaped blade of the anterior hamulus and its characteristic wide (wing-like) shaft, serrated on one side, smaller posterior hamulus with a distinct short and broad shaft that widens and is serrated distally, more extensive dimensions of the penis and its pear-like shape, smaller vagina diameter, ovoid egg shape with more pointed anterior pole and blunt posterior pole and long coiled filament as well as different type species of the host in a geographically distant type locality. Genetic data accompanied the description, and phylogenetic analyses inferred that the new species clustered with monogenean species positioned under the family Capsalidae. Molecular data were generated for the 18S and 28S genes of the ribosomal RNA of P. johnstoni sp. n. to provide the first molecular analysis for Pseudobenedeniella species. EDXA for a species of Pseudobenedeniella was offered for the first time.

期刊介绍: Helminthologia (HELMIN), published continuously since 1959, is the only journal in Europe that encompasses the individual and collaborative efforts of scientists working on a different topics of human, veterinary and plant helminthology. The journal responsibility is to enrich the theoretical and practical knowledge in very specific areas and thus contribute to the advancements in human and veterinary medicine and agronomy. Taking the advantage of comprehensive and multidisciplinary approaches journal still maintains its original spirit and is principal source of fresh scientific information regarding helminths, endoparasites and plant parasites. Addressing the most up-to date topics journal gained rightful and exceptional place next to the other high-quality scientific journals publishing in its field.
