DESCRIPTION AND ECOLOGY OF A NEW SOLIFUGE FROM BRAZILIAN AMAZONIA (ARACHNIDA, SOLIFUGAE, MUMMUCIIDAE)

Three regions of Brazilian Amazonia within the state of Rondônia were searched for the presence of solifuges by means of pitfall traps. A new solifuge, Mummucia taiete, was found at two sites inside Vilhena region, which are “Cerrado” enclaves surrounded by Amazonian forest. This new species is desc...

Description
Summary:Three regions of Brazilian Amazonia within the state of Rondônia were searched for the presence of solifuges by means of pitfall traps. A new solifuge, Mummucia taiete, was found at two sites inside Vilhena region, which are “Cerrado” enclaves surrounded by Amazonian forest. This new species is described here and is the seventh from Brazil. Populations of M. taiete from these two sites were compared regarding some autoecological parameters. Results showed populations from the two sites are similarly diurnal and male biased, as observed in M. mauryi and M. coaraciandu. On the other hand, these populations differ in density and juvenile/adult ratio. RESUMO.Três regiões da Amazônia brasileira pertencentes ao Estado de Rondônia foram investigadas quanto à presença de Solifugae por meio de armadilhas “pitfall”. Um novo solífugo, Mummucia taiete, foi encontrado dois locais no município de Vilhena, que são enclaves de Cerrado circundados por floresta Amazônica. Esta nova espécie de Solifugae é descrita aqui e é a sétima do território brasileiro. Populações de Mummucia taiete desses dois locais foram comparadas quanto a alguns parâmetros autoecológicos. Resultados indicam que as populações se assemelham pelos hábitos diurnos e pelo maior número de machos, como observado para outras espécies como Mummucia mauryi and Mummucia coaraciandu.Por outro lado, essas populações diferem em densidade e na razão jovens/adultos.
