Lernanthropus antofagastensis sp. nov., parasitic on Anisotremus scapularis, and inshore fish of Antofagasta, Chile, is described and illustrated. It resembles five other species of Lernanthropus in its dorsal plate and third leg, but can be distinguished from them by a combination of characters. L. trachuri Brian, 1903, is recorded, its male described and illustrated from specimens collected from Seriolella violacea and Trachurus murphy, taken in the same locality. 相似文献

Natural history data on snakes collected in situ are scarce because of the great sampling effort required to record individuals with methods that do not interfere with their activities (e.g. visual surveys). We collected data on relative abundance and natural history, including records of ingested prey, microhabitat use, and behaviour of a snake assemblage along transects marked alongside a river in south-eastern Brazil. We recorded eight species from two families, Viperidae and Dipsadidae using visual searches over 12 months. We quantified available microhabitats in the sampled transects and used electivity indices to determine preferred microhabitats for the pit viper Bothrops moojeni, the most frequent species. Several species of snakes use riverside habitats where they can find food and suitable microhabitats, even in areas that are not pristine, adding to the importance of preserving the remaining riverside vegetation and habitat structure in such areas. 相似文献

Two new genera and five new species of feather mites of the family Proctophyllodidae are described from passerine birds from Brazil: Tyranniphyllodes pitangi gen. n., sp. n. from Pitangus sulphuratus (Tyrannidae); Atrichophyllodes delalandi gen. n., sp. n. from Corythopis delalandi (Tyrannidae); A. mentalis gen. n., sp. n. from Dysithamnus mentalis (Thamnophilidae); Anisophyllodes candango sp. n. from Elaenia chiriquensis (Tyrannidae); and Platyacarus sittasomi sp. n. from Sittasomus griseicapillus (Dendrocolaptidae). The discovery of these taxa might give data for a better understanding of the evolution of the family Proctophyllodidae in general and the dispersion of these mites on passerines in South America in paricular. 相似文献
