Linnavuori, 1959 described the genus and species Andanus bimaculatus based on four specimens collected in Peru, Madre de Díos. In examining the type-material, we found that it was formed by two species belonging to a different genus. The female specimen (alotype) and one of the two males paratypes, that Linnavuori used to dissect the genitalia, is here described as Perundanus raunoi, gen.n., sp.n. Fora better characterization of the genus Andanus Linnavuori and A. bimaculatus Linnavuori , both are redescribed.
