ARA？AS CHILENAS: ESTADO ACTUAL DEL CONOCIMIENTO Y CLAVE PARA LAS FAMILIAS DE ARANEOMORPHAE

the studies of the chilean arachnofauna have been scarce during the past years and there is a lack of texts and identification keys to help taxonomical and biological studies in chile. therefore the knowledgment is still poor. a total of 55 families are reported for chile, 6 belonging to mygalomorphae and 49 to araneomorphae, which represents around the 50% of the world known families. only 51 are reconized for chile in this study. it is important to develop new systematic studies of the spiders present in chile to determine their biology, geographical distribution and diversity. biological information and a dicotomic key for the more common families of araneomorphae are given. mygalomorph families and the araneomorph families amphinectidae, clubionidae, desidae, synotaxidae, tengellidae y titanoecidae and are not included in the present key due to taxonomical problems of the later ones
