Amphibians are hosts for a wide variety of ecto-and endoparasites, such as protozoans and parasitic worms. Naididae is a family of Oligochaeta whose species live on a wide range of substrates, including mollusks, aquatic macrophytes, sponges, mosses, liverworts, and filamentous algae. However, some species are known as endoparasitic from vertebrates, such as Dero (Allodero) lutzi, which is parasitic of the urinary tracts of frogs, but also have a free-living stage. Specimens in the parasitic stage lack dorsal setae, branchial fossa, and gills. Here we report the occurrence of D. (A.) lutzi associated with anuran Scinax fuscovarius from Semi-deciduous Atlantic Rain Forest in southern Brazil. The study took place at the Caiuá Ecological Station, Diamante do Norte, Paraná, southern Brazil. Seven specimens of S. fuscovarius were examined for parasites but only one was infected. Parasites occurred in ureters and urinary bladder. Previous records of this D. (A.) lutzi include the Brazilian States of Santa Catarina, São Paulo, Rio de Janeiro, and Minas Gerais, as well as Cuba and North America. This is a new locality record for this species in Brazil. Reports of Dero (Allodero) lutzi are rare, due to difficulty of observation, and such events are restricted only the fortuitous cases. It is important to emphasize the necessity of future studies, which are fundamental to the understanding of biological and ecological aspects of this species.Keywords: anuran, Hylidae, endoparasite, urinary tract, Annelida.

“…The species' distribution patterns and habitat specificity are given in the Table . The present survey records the species Aulophorus furcata, Aulophorus vagus, and Dero digitata in wetlands richly covered by macroalgae. The worms of the family Naididae can live on a considerable range of substrates, including aquatic macrophytes (Glowacka et al, 1976;Mastrantuono, 1986), mosses, liverworts (Vlckva et al, 2002), and filamentous algae (Armendariz, 2000). Three to 5 individuals of Aulophorus vagus were found in tubular nests of 1-2 cm in length.…”

The fauna of aquatic oligochaetes (microdriles) of Karnataka, India is poorly known. The aim of the present survey was to prepare the preliminary checklist of microdrile worms present in the freshwater bodies of Western Ghats and the west coast of Karnataka. The wetland ecosystems are mostly perennial and host a large number of species. However, they are exposed to various environmental factors including rainfall, changes in chemicals, pH, growth of macroalgae and macrophytes, decay of plant and animal materials, and human activities such as fishing. The aquatic oligochaetes are the most important microinvertebrates, adapted to every kind of water such as saltwater, brackish water, and freshwater, including small streams, large rivers, marshes, ponds, lakes, springs, and groundwater. They are found in algae, aquatic vegetation, floating rotting material, and bottom mud (Wetzel et al., 2000). They are an important food source for some invertebrate and fishes. They can be of importance in water management because of their potentially high densities (Brinkhurst and Jamieson, 1971), their wide distribution, and their indicator value (Milbrink, 1973;Chapman et al., 1982;Särkkä, 1994). They display a great diversity in aquatic bodies, including over 1700 species. Of these, about 1100 species are freshwater species and others are primarily terrestrial, belonging to the family Enchytraeidae (Martin et al., 2007). The ecological value of oligochaetes includes their importance in aquatic food chains, their impact on sediment structure and water-Abstract: A survey on freshwater oligochaetes was conducted between October 2011 and June 2013 in selected wetlands of the Dakshina Kannada, Udupi, and Shimoga districts of Karnataka, India. In this study, 260 wetlands were sampled and examined for the presence of microdriles. Sixteen species of aquatic oligochaetes were recorded. Of these, 10 species belonged to the family Naididae (monophyletic) and 6 species to the family Pristinidae. The species' distribution patterns in different water bodies and habitat specificity (if any) in the study area are presented.

The metacommunity theory includes processes that contribute, at different scales, to the understanding of the distribution of organisms in space and aims to assess the relative importance of spatial and environmental factors in the structuring of communities. Fluvial ecosystems of the Argentine Pampas are characterized by their environmental heterogeneity from slow water courses and variable development of aquatic vegetation to faster courses. They are affected by the different land uses, which are among the main threats to biodiversity and alter the dispersal of the species. Forty-four species of aquatic oligochaete assemblages from 15 streams of nine Pampean basins were seasonally analyzed. The assemblages were characterized through estimations of taxonomic richness, α and β diversity. No differences were found in the assemblages of the substrates (sediments and aquatic vegetation) within each stream, except for Juan Blanco stream. However, differences were found between streams, as well as between basins. The oligochaetes that contributed most to the dissimilarity among streams and basins were Nais communis, Limnodrilus hoffmeisteri, Dero obtusa, and Stylaria fossularis. Two groups of sites were identified through the analysis of canonical correspondence: those of mountain basins and those of lowland basins. The variance partitioning showed that local environmental conditions (acting as environmental filters) accounted for 15.64% in the ordering of the assemblages, while 14.60% was explained by altitude and geographic factors (as a dispersal limitation). These results help to understand the processes that organize the distribution of organisms at different scales, which could have important implications when making decisions regarding biomonitoring and conservation.
