A new species, Ceratophysella stachi, from Denmark, Germany, Luxembourg, Norway, Poland, and Ukraine is described based on morphological data and DNA barcodes. It belongs to a small European group of species with type B chaetotaxy and strong tegumentary granulation with distinct fields of coarse granules: C. granulata Stach, 1949, C. lawrencei (Gisin, 1963), C. neomeridionalis (Nosek & Červek, 1970), C. scotica (Carpenter & Evans, 1899), and C. silvatica Rusek, 1964. It differs from all of them in the chaetotaxy of lateral parts of thoracic terga II–III (setae m₆ present and one additional seta outside lateral sensillum m₇ present or absent) that is exceptional within the whole C. armata-group. Notes on closely related species C. granulata are also given.
