%X Basado en muestreos de tres a os consecutivos y revisi¨®n de literatura, describimos la composici¨®n, singularidad y estado de conservaci¨®n de la ictiofauna del r¨ªo San Pedro, en la cuenca del r¨ªo Valdivia. Adem¨¢s, analizamos los posibles or¨ªgenes de esta ictiofauna, postulando que parte de la cuenca del r¨ªo Valdivia ha funcionado como un sumidero, principalmente su parte alta, con aportes de fuentes tanto costero-Pac¨ªficas como del Este de Los Andes. Concluimos que el r¨ªo San Pedro es de particular valor ictiofaun¨ªstico por su alta riqueza espec¨ªfica, endemismos y caracter¨ªsticas biogeogr¨¢ficas. Based on three consecutive years of sampling and bibliographic revision, the composition, singularity and conservation status of the San Pedro River ichthyofauna is described. In addition, the potential origin of this Valdivia River ichthyofauna was analyzed and this basin is proposed to have worked like a sink, mainly the higher zone, having been colonized both from Coastal-Pacific as from Eastern Andes sources. It is concluded that this river has a particular conservation value due to its high species richness, endemism and biogeographic characteristics.
