Abstract

With the main objective of characterizing the herpetofauna of Urucu, six expeditions were carried out between 2003 and 2008, when five collection methodologies were employed, considered complementary: Interception and Fall Traps, Time Limited Search on foot, Time Limited Search by car, Occasional Encounters and Collections by Third Parties. In total, 407 individuals were collected, distributed in three orders, 24 families and 106 species, of which 38 species of annelids belonging to the order Anura and 68 species of reptiles, distributed in two orders, Squamata and Crocodylia. In order to carry out the inventory at the Geologist Pedro Moura Base, located between parallels 4° 51' 18" and 4°52'16" 5 and meridians 65° 17' 58" and 65° 20' 01" W, municipality of Coari, state of Amazonas, six expeditions were carried out during the years 2003, 2004, 2007 and 2008, in which 37 collection points were sampled. Through a sample effort I of 2400 hours/ bucket of AIQ's, 422 hours/man for PLTand 51,S hours for PLTc, 407 individuals were collected, distributed in three orders, 24 families, 66 genera and 106 species. For amphibians, 38 species (n=167) were recorded, distributed in 10 families, all belonging to the order Anura, the only order of amphibians recorded so far. A família Hylidae foi a mais abundante com 55 indivíduos coletados, seguida da família Bufonidae (n=41) e Leptodactylidae (n=30) (Figura 1). Em relação aos répteis foram registradas 68 espécies (n=240), distribuídas em 14 famílias e duas ordens (Squamata e Crocodylia). Dentro dos Squamata, foram registradas 47 espécies de serpentes distribuídas em seis famílias, 18 espécies de lagartos também distribuídas em seis famílias e uma espécie, de uma única família, de anfisbena. A família Colubridae foi a mais representativa entre as serpentes e entre todas as famílias dos demais grupos acessados, com 42 espécies (n= 135). Entre os lagartos, as famílias mais abundantes foram Gekkonidae (n= 13), Polychrotidae (n=12) e Teiidae (n=13).
