Fridericia brunensis sp. n. (Clitellata: Enchytraeidae), a species similar to F. monochaeta Rota, 1995 with single dorso-lateral chaetae in most postclitellar segments, preclitellar chylus cells, large seminal vesicle, large sperm funnels, and fused spermathecal ampullae is described based on material from a municipal forest of the city of Brno, Czech Republic. In comparison to its co-geners the species seems very tolerant to acidic and dry conditions. Additional records from Hungary and Germany are discussed.
