Morfologia hemipeniana de 11 espécies do gênero Micrurus Wagler, 1824 na Amazônia Brasileira, com redescrição de Micrurus filiformis (Günther, 1859) e Micrurus paraensis Cunha & Nascimento, 1973 (Serpentes, Elapidae)

Micrurus includes snakes of semi-fossorial, terrestrial and semi-aquatic habits, distributed from the southern United States to southern Argentina. From the 66 currently valid species, 25 are registered on the Brazilian Amazonia. In order to improve the knowledge on this group Brazilian Amazonia Micrurus, data about pholidosis, hemipenis and geographic distribution of 542 individuals of 11 species were collected. The present work contains two chapters. The first one is a comparative description of hemipenis from 11 Micrurus species. Diagnosis, coloration pattern, hemipenis description, geographic distribution are presented for each taxon. The hemipenis of M. hemprichii ortonii and M. paraensis are described for the first times. The second chapter presents more thorough a description of two species, M. filiformis and M. paraensis, based on the external hemipênis.

Serpentes da Bacia Petrolífera de Urucu, município de Coari, Amazonas, Brasil

A structured snake inventory was carried out at the Base Operacional Geólogo Pedro de Moura (BOGPM), located at the Urucu Petrol Basin, Municipality of Coari, Amazonas, during 2003, 2004 and 2007. Throughout four sampling expeditions (51 collection days), seven species of snakes, belonging to seven families and 33 genera, were recorded. Four complementary sampling methods were used: pitfall traps with drift fence, occasional encounters, time-limited search on foot and time-limited search by car. Of the 47 collected species Liophis reginae (n= 14), Philodryas viridissima (n= 9), Philodryas boulengeri (n= 7) and Oxybelis fulgidus (n= 7) were the most abundant in the region. The highest number of species and specimens was obtained by the time-limited search by car (n=52.8%). Previous studies indicate that localities south of the Amazonas river (such as the eastern region of Pará and Tucuruí, state of Para, and Samuel Hydroelectric Plants, state of Rondônia) present a greater richness when compared to those north of the Amazonas river (such as the mucipality of Manaus, INPA-WWF Reserve and Balbina Hydroelectric Plant, state of Amazonas).Thus, it is possible to infer that the snake inventory in Urucu region is not yet complete, requiring more sampling efforts so that new records can be obtained for the area.
