AbstractWe analyzed the breeding biology in a population of the hylid Scinax trapicheiroi and evaluated how some environmental and structural factors affect the temporal and spatial distribution of the clutches. Fieldwork was carried out at a small stream running inside the Atlantic Rainforest at Ilha Grande, an island in Rio de Janeiro State, southeastern Brazil, from October 2000 to September 2001. Breeding occurred all year round, but the presence of females and clutches was affected by rain from the previous days. Clutches had an aggregate distribution, because they were mainly laid on lentic waters (with slow water flow). Rain affected the availability, stability and size of ponds. The high numbers of eggs per clutch, and the fast development of eggs and larvae are influenced by an unpredictable environment.

Two new species of Dilobopterus Signoret, 1850 are described from the Atlantic Rainforest of Rio de Janeiro State, Southeastern Brazil, based on specimens collected in Angra dos Reis (D. nelsoni sp. nov.) and Itatiaia (D. sakakibara sp. nov.). Holotypes are deposited in Museu Nacional, Universidade Federal do Rio de Janeiro. These are the first species of the genus described after the publication in 1977 of the last comprehensive monograph on the New World Cicadellini. We also describe the previously unknown male of D. segmentalis (Signoret, 1853) based on specimens from the Atlantic Rainforest of Espírito Santo State, Southeastern Brazil (municipality of Santa Teresa). We propose a group of species within Dilobopterus (trinotatus group) based on features of the paraphyses of D. trinotatus (Signoret, 1853), D. segmentalis, and D. sakakibara sp. nov..

We studied the ectoparasite and the Amblyopinini beetle fauna associated with four small mammal species of the Atlantic Rainforest of Ilha Grande, an island located off the southern Rio de Janeiro State Coast, Southeastern Brazil, analyzing to what extent the parasites were specific to each region of the host body. During the study, a total of 90 individual rodents were captured: 61 Proechimys iheringi Thomas, 1911 (Echymyidae), 22 Sciurus aestuans (Thomas, 1901) (Sciuridae), 4 Oxymycterus sp. (Waterhouse, 1837), and 2 Nectomys squamipes (Brants, 1827) (Sigmodontinae). The data showed that the ectoparasites and Amblyopinini on some rodent hosts in Ilha Grande tend to prefer particular host body sites, and that some ectoparasite species sites may overlap owing to their inaccessibility to the host.

A new species of Asclepiadoideae (Apocynaceae) with enigmatic taxonomic position was found in the Atlantic rainforest of Rio de Janeiro State, southeastern Brazil. To ascertain its affinities within the Asclepiadeae, we performed phylogenetic analyses using the plastid regions trnT-L and rps16. Our results strongly support the new species close to the Orthosiinae, but do not support any generic relationship for this species. Based on the floral morphology, especially the corona lobes, which are highly fused, and curved inward at the top, covering the gynostegium, the new species is assigned to Monsanima. This genus is sister to the other Orthosiinae and included so far only one species narrowly endemic to the campos rupestres of Bahia, in northeastern Brazil. The new species, Monsanima tinguaensis, occurs in a protected area, Tinguá Biological Reserve. However, it is known only by the type specimen and is probably vulnerable to extinction.

We report a list of the amphibians from the Parque Estadual do Cunhambebe (22°54’07” S, 43°53’33” W) in Itaguaí municipality, an area of Atlantic Rainforest in Rio de Janeiro State, southeastern Brazil. The work was carried out from January to November 2010. We recorded 28 species of anuran amphibians distributed in eight families: Brachycephalidae (3), Bufonidae (2), Craugastoridae (1), Cycloramphidae (2), Hylidae (13), Hylodidae (2), Leiuperidae (1) and Leptodactylidae (4). Adding the species recorded in the Parque Estadual do Cunhambebe in Mangaratiba municipality, the richness of amphibians in the park currently is now 47 species.

We studied and compared parameters of the snake community of the Serra do Mendanha, Rio de Janeiro State, southeastern Brazil (22º 48'-22º 51' S and 43º 31'-43º 28' W), such as: abundance distribution, richness, species diversity and biomass, between forested areas, areas under regeneration and agriculture areas (banana plantations); to obtain information about the natural history and facilitate the development of future research. For capturing the snakes we used: pitfall traps, drift-fences and visual search (diurnal and nocturnal) along four transects for each habitat. The captured snakes were measured with a tape and caliper, weighed with dynamometers and sexed with the use of a catheter. The animals marked (with ventral scales cut) were released for posterior recapture. One individual per species was fixed and deposited at the Museu Nacional, Rio de Janeiro. We undertook an effort of 840 man/hour, and captured a total of 207 snakes belonging to 25 species (Colubridae 80.2%, Elapidae 12.6%, Viperidae 6.3% and Boidae 0.9%). The most abundant were: Liophis miliaris (n = 33), Micrurus corallinus and Chironius fuscus (both with n = 26); the least abundant: Elapomorphus quinquelineatus, Siphlophis compressus and Tropidodryas serra (all with n = 1). The species that contributed the greatest biomass were Spilotes pullatus (7,925 g), Chironius laevicollis (4,694 g), Liophis miliaris (3,675 g) and Pseustes sulphureus (3,050 g); those that contributed the lowest biomass were: Siphlophis compressus, Tropidodryas serra (both with 4 g) and Elapomorphus quinquelineatus (3 g). We found significant differences between the sampled habitats at the Serra do Mendanha (undisturbed forest, secondary forest and banana plantations). The results showed that a great reduction in the abundance, richness, diversity and biomass of the snakes occurs when the native forest is replaced by banana plantations.

We report here on an albino specimen of Schizolecis guntheri caught in the rio Bonito in the rio Macaé basin, Rio de Janeiro State, southeastern Brazil. The hypothesis that albinism is more common in fishes with cryptobiotic and/or nocturnal habits is strengthened by additional records of this chromatic anomaly.

Helminth Parasites

Our study aimed to add information about the diet and endoparasites of Enyalius brasiliensis from an Atlantic Rainforest remnant in the state of Rio de Janeiro, southeastern Brazil. Regarding diet, E. brasiliensis consumed arthropods, with caterpillars and beetles being the most important preys. Regarding helminth parasites, overall prevalence was low (9.5%), with 238 nematodes of the genus Physaloptera found in the stomach of one specimen and one nematode of the genus Rhabdias inside the lung of another. Our results corroborate the observations of previous studies that indicate that lizards of the genus Enyalius tend to feed mainly on relatively large-bodied arthropods and to harbour depauperate endoparasite fauna.
