Although it was not possible to identify the scales found in the stomach content of E. iheringii, probably they are a result of its own molt.…”

ABSTRACT. Studies on the natural history of the lizard Enyalius iheringii Boulenger, 1885, as well as other tropical lizards, are rare. In this study, some aspects of the natural history of this endemic species from the Atlantic forest are reported in areas of Vale do Itajaí, state of Santa Catarina, Brazil. Twenty individuals were found, of which 18 were collected. Most of them were found over the vegetation (n=17) and on the ground (n=3). The main defensive strategy displayed was camouflage (n=16). Jumping (n=1), jumping and running (n=1) and running (n=2) were also observed in some individuals. When handled, lizards exhibited mouth wide open, hissing, and occasionally biting, as well as color change in males. Regarding its diet, the numerically most important prey was beetles (Coleoptera), followed by Lepidoptera larvae. Beetles, lepidopteran larvae and spiders were the most frequent food items. Males and females did not differ in size. Three sexually mature females (100-113 mm SVL) were found in December and January.KEYWORDS. Diet, reproduction, defensive behavior, microhabitat use. RESUMO. História natural do lagartoEnyalius iheringii (Squamata, Leiosauridae) no sul da Mata Atlântica. Informações sobre a história natural do lagarto Enyalius iheringii Boulenger, 1885 são escassas, assim como para várias espécies de lagartos de florestas tropicais. Neste estudo abordamos vários aspectos da história natural desta espécie endêmica da Mata Atlântica, na região do Vale do Itajaí, Santa Catarina. Encontramos 20 indivíduos, dos quais 18 foram coletados. A maioria foi encontrada sobre a vegetação (n=17) e o restante sobre o solo (n=3). A camuflagem foi a principal tática defensiva utilizada (n=16), apesar de também observarmos salto (n=1), salto e corrida (n=1) e corrida (n=2). Quando manipulados, apresentaram o comportamento de escancarar a boca, emissão de silvos e eventualmente mordidas, assim como mudança de coloração em machos. Com relação à dieta, as presas mais consumidas foram coleópteros, seguidos por larvas de lepidópteros; em relação à frequência, os itens mais representativos foram coleópteros, seguidos por larvas de lepidópteros e aranhas. Machos e fêmeas não diferiram em relação ao tamanho do corpo. Três fêmeas reprodutivas (100-113 mm CRC) foram encontradas nos meses de dezembro e janeiro. PALAVRAS-CHAVE.Dieta, reprodução, comportamento defensivo, uso do microhábitat.

Feeding habits of Enyalius perditus (Squamata: Leiosauridae) in an Atlantic Forest remnant in southeastern Brazil. In the present study, we aimed to provide information regarding feeding habits and other ecological aspects of Enyalius perditus in an Atlantic Forest remnant in the state of Rio de Janeiro, southeastern Brazil. Enyalius perditus individuals in Rio de Janeiro fed predominantly upon arthropods such as caterpillars, isopods, and spiders, as is typical of lizards in the genus. There were no pronounced variations in the main types of prey consumed between this and other populations of E. perditus studied in spite of potential differences in local food supplies between environments. The individuals consumed fragments of dead leaves, ingested prey commonly found in leaf litter (e.g., Isopoda and Coleoptera larvae), and were sometimes also use perches above ground level. Our study provides additional information and lizards of the genus Enyalius.Keywords: diet, leaf litter, lizard, microhabitat use, perch height. 22Phyllomedusa -15(1), June 2016 Resumo Hábitos alimentares de Enyalius perditus (Squamata: Leiosauridae) em um fragmento de Mata Atlântica no sudeste do Brasil. O objetivo do presente estudo foi fornecer informações sobre hábitos alimentares e outros aspectos ecológicos do lagarto Enyalius perditus em um fragmento de Mata Atlântica no estado do Rio de Janeiro, sudeste do Brasil. No Rio de Janeiro, os indivíduos de E. perditus alimentaram-se predominantemente de artrópodes, como lagartas, isópodes e aranhas, como é típico de lagartos desse gênero. Não houve variação pronunciada nos principais tipos de presas consumidas entre essa e outras populações de E. perditus estudadas, apesar de haver diferenças potenciais nos suprimentos alimentares entre ambientes. Os indivíduos consumiram fragmentos de folhas mortas, ingeriram presas comumente encontradas na serapilheira (e.g., Isopoda e larvas de Coleoptera) e foram algumas vezes encontrados no chão ou capturados em armadilhas-de-queda durante os trabalhos de campo, o que sugere que esses lagartos utilizam a serapilheira do chão da chão. Nosso estudo fornece informações adicionais e reforça a ideia do uso tanto da vegetação como Enyalius.Palavras-chave: altura do poleiro, dieta, lagarto, serapilheira, uso de micro-habitats.
