We studied the parthenogenetic lineages of the spider Dysdera hungarica (Araneae: Dysderidae). Based on our data, we consider them to constitute a separate taxon, Dysdera parthenogenetica sp. nov. Morphologically, the new species differs mainly by slightly reduced female copulatory organs. The ovaries contain meiotic cells, suggesting that automictic thelytoky occurs in this species. D. parthenogenetica sp. nov. colonised areas west of the ancestral sexual species D. hungarica , especially the P
