While revising specimens of Philoscia muscorum in the collection of the Royal Belgian Institute of Natural Sciences (RBINS), one male Philoscia affinis was found which apparently was collected in the UK in 1985. Since Philoscia affinis was not known as a native species for the UK it was uncertain if the specimen was indeed caught in the UK or if the sample was just mislabelled. During a field trip in July 2017 several locations were visited in search of the species. Eventually, Philoscia affinis was found in South East England, which confirms its presence in the UK. Further, the identification, habitat preferences and distribution of Philoscia affinis in the UK and Europe are discussed in this article.
