| We analyzed stomach contents of 58 specimens of Teius oculatus (D'Orbigny & Bibron, 1837) (20 adult males, 17 adult females and 21 juveniles) captured in Dom Feliciano, RS, Brazil, to evaluate diet composition and sexual and ontogenetic variations in prey consumption. Diet was composed of 15 prey categories, all arthropods. Orthoptera was the most frequent prey type. Quantitatively, termites were the most important prey item (59.5%). There were no significant differences between the diets of adult males and females. Ontogenetic differences were found, mainly concerning volume of prey consumed. Adult lizards ingested significantly larger prey than juveniles (U = 170.00; p < 0.001). Juveniles, although having a comparatively less diverse diet (10... |

| Boiruna maculata Boulenger, 1896 and Clelia rustica (Cope, 1878) were observed in captivity feeding snakes and rodents, respectively. Both species have shown a similar procedure in relation to the prey. Major behavior differences among the two species were: rodents killed before being swallowed, and snakes were mostly swallowed alive; both species are able to find the rodents head faster than the snake one; the coils formed during constriction were also used to hold the prey, specially the last coil, while swallowing rodents. Informations on stomach contents was gathered by dissection of preserved specimens of Clelia clelia (Daudin, 1803) and C. plumbea (Wied, 1820) were also included in the dietary study. The majority of preys consisted on snakes and... |

| A comparação dos espécimes-tipo de Phalotris tricolor (Duméril, Bibron & Duméril, 1854) e Elapomorphus punctatus Lema, 1979 demonstrou que ambos nomes se referem ao mesmo táxon; o nome P. tricolor, empregado até o momento, é um complexo de P. tricolor e uma espécie ainda não conhecida, descrita aqui como P. matogrossensis sp. nov. distribuída do sudoeste do Brasil às áreas adjacentes no Paraguai, em formações de Cerrado. A nova espécie difere de P. tricolor principalmente por apresentar região inferior da cabeça branca, ao invés de inteiramente preta; colar branco mais longo que o preto; ao invés de curto e com um colar preto muito mais longo; colar preto apenas dorsal, ao invés de atingir os lados do ventre; coloração dorsal de fundo vermelha... |

| ABSTRACT During a faunal rescue conducted at a hydroelectric power station constructed in a Cerrado savanna area in the state of Mato Grosso, a sample of five small stripe-patterned individuals of snakes of the genus Apostolepis Cope, 1862 document the existence of an undescribed species, which is named herein. The new species can be distinguished from its congeners by a combination of scale counts, number of maxillary teeth and color pattern. The new species is most similar to Apostolepis borellii Peracca, 1904, A. lineata Cope, 1887, A. nelsonjorgei Lema & Renner, 2004, A. nigroterminata Boulenger, 1896, A. serrana Lema & Renner, 2006 and A. underwoodi Lema & Campbell, 2017 in its coloration pattern. However, it is distinguished from these... |

| This paper reports the preliminary results of two years of herpetogeographic studies in the region called «Grande Porto Alegre» at its northern portion. The physiognomy shows, at North, slopes of the Brazilian Southern Plateau, more or less forested in a general view; these elevations graãuálly decrease to the South until the levei of the sea to Atlantic littoral by the eastern border, and to Rio Grande do Sul savanah, which extends to Uruguay and Argentina. The biota is transitional from the highland prairies and forests of the plateau to lowland prairies of the pampas. Three faunistic Provinces are included: Guarani, Pampean, and Tupi. The most conspicuous dispersion is shown by the taxa proceeding from the plateau to savanah (Dispersion Centre Guarani);... |
