The family Atypidae is reported from Rovno amber for the first time on the basis of a juvenile specimen described here as Atypus sp. It is fourteenth family of spiders reported from Rovno amber. Balticatypus Wunderlich 2011, a genus known from three species from Baltic amber, and the tribe Balticatypini Wunderlich 2011 are synonymised with Atypus Latreille 1804 and Atypini Thorell 1870 respectively. The diagnoses of the fossil genus and tribe were primarily based on the relative size of spinnerets of the first nymph, which are subjects of the ontogenetic changes. Our study reveals that the nymphs of the extant European species of Atypus have the same size and shape of the spinnerets as in the species described from the Baltic amber.
