Until recently, six species of silverfish have been reported from the Netherlands. Four of these are associated with humans and spend their lives predominantly indoors. Some silverfish species are obligatory myrmecophilous, meaning they live inside ant nests. In this paper we present a new silverfish species for the Netherlands, and the first myrmecophilous one. Considering its small size and cryptic lifestyle, it has probably been overlooked until now, as is proven by a dedicated search in the south of the country.
