A femaleAlopecosa albofasciata(Brullé, 1832) with two well developed epigynes placed side by side was collected near Trento, Northern Italy. This case appears to be different from the three other occurrences of this abnormality hitherto known, since the two epigynes do not result from presumable duplication of abdominal segments. This abnormal duplication is likely to be due either to secondary subdivision of the uterus or to lack of fusion of the two oviducts; the development of the two epigynes could be induced by the two underlying gonoducts.
