Abstract The leech family Barbronidae is distinguished from the Salifidae and Erpobdellidae by the presence of two accessory copulatory pores, and by the ventral nerve cord with 19 free ganglia and 9 ganglia fused to form the posterior ganglionic mass. Some characteristics of Barbronia assiuti are revised, such as the presence of stylets and the annulation.
