Description	Compared with araneomorph spiders, karyotypes of the spider infraorder Mygalomorphae are nearly unknown. In this study we investigated karyotypes of European species of the genus Atypus (Atypidae). The male karyotype of A. muralis and A. piceus comprises 41 chromosomes, whereas female complements contain 42 chromosomes. On the other hand, both sexes of A. affinis possess 14 chromosomes only. It is the lowest diploid number found in mygalomorph spiders so far. Furthermore, obtained data suggest X0 sex chromosome system in A. piceus, A. muralis and neo-XY system in A. affinis. Karyotypes of all three Atypus species are composed of biarmed chromosomes only. Thus they differ significantly from the karyotype of A. karschi , the only other species of this genus studied so far.
