Última A new genus and two new species of minute leptodactylid frogs from northern South America, with comments upon Phyzelaphryne (Amphibia: Anura: Leptodactylidae) Naturalis Hoogmoed, M.S.; Lescure, J.. The synonymisation of Phyzelaphryne miriamae Heyer with Eleutherodactylus nigrovittatus Andersson is denied and it is shown that both species are quite distinct in numerous characters. A new genus (Adelophryne) of minute leptodactylid frogs with pointed discs on the toes and a distinctly reduced fourth finger, containing two new species (A. adiastola spec. nov. and A. gutturosa spec. nov.) is described from northern South America. A key to separate the diminutive leptodactylid frogs with pointed toetips is given. The relationships of the new genus are not clear, but possibly are with one of the species groups of Eleutherodactylus, of the subfamily Eleutherodactylinae.

Ano: 1984 URL: http://www.repository.naturalis.nl/record/319080 Cytogenetics of three Brazilian species of Eleutherodactylus (Anura, Leptodactylidae) with 22 chromosomes and re-analysis of multiple translocations in E. binotatus Genet. Mol. Biol. Siqueira-Jr.,Sérgio; Ananias,Fernando; Recco-Pimentel,Shirlei M.. In this paper, we provide a cytogenetic analysis of Eleutherodactylus guentheri, E. parvus and E. binotatus. All of the species had a diploid chromosomal number of 2n = 22. The karyotypes of E. guentheri and E. parvus were very similar and differed only slightly in the morphology of pair 2. These two species also had an NOR-bearing secondary constriction on the long arms of pair 6. The karyotype of E. binotatus differed from those of E. guentheri and E. parvus in the morphology and size of the chromosomes, in the number of chromosomal arms, in the NOR location (detected on the short arms of pair 1), and in the pattern of heterochromatin. These results reinforce the differences between E. guentheri and E. binotatus and support the existence of two species...

Ano: 2004 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1415-47572004000300010 Diversity and abundance of litter frogs at altitudinal sites at Serra do Japi, southeastern Brazil Zoologia Giaretta,Ariovaldo Antonio; Sawaya,Ricardo J.; Machado,Glauco; Araújo,Márcio S.; Facure,Kátia G.; Medeiros,Hermes F. de; Nunes,Renato. It was sampled the litter frogs at altitudinal sites of a semideciduous mesophytic forest located at Sena do Japi (Jundiaí, São Paulo, 23º17'S, 47º00'W, 800-1300m altitude, 1500mm rain/year). Forty two plots of 8x8m were sampled in the dry/cold season of 1995: 21 at a Higher Site (HS) (1000m) and 21 at a Lower Site (LS) (850m). The plots were evenly located near, mid-distance, and far from the stream-bed. It was found a total of five species, three at each site. Eleutherodactylus guentheri comprised 83% of the individuals at HS and E. juipoca 67% at LS. The density of individuals was higher at HS and near the stream. The greater density at HS may be due to greater humidity there, provided by mist. The frogs may aggregate in wetter places (stream edges) in...
