Abstract

Twelve new species of the genus Stethorrhagus Simon, 1896 are described: S. bradypus sp. nov. (♂♀), S. callithrix sp. nov. (♂♀), S. loxodonta sp. nov. (♂♀), S. naja sp. nov. (♂♀), S. papilio sp. nov. (♀) and S. sylvilagus sp. nov. (♂♀) from Colombia; S. canis sp. nov. (♀), S. felis sp. nov. (♂♀), S. mandrillus sp. nov. (♂♀), S. ovis sp. nov. (♂♀), S. sciurus sp. nov. (♀) and S. tremarctos sp. nov. (♂♀) from Ecuador, increasing the number of known species in the genus from 15 to 27. Detailed morphological descriptions, photos of the body and copulatory organs, illustrations of copulatory organs, and comparisons with closely related species are given for all new species, along with emended diagnoses, distribution maps and an updated key to all currently accepted species in the genus. The geographical distribution of S. lupulus and S. oxossi are updated with new records from Brazil and Peru, and Brazil, respectively. Additionally, photographs of the type material of S. limbatus Simon, 1896, S. nigrinus (Berland, 1913), S. maculatus (L. Koch, 1866), S. hyula Bonaldo & Brescovit, 1994, S. planada Bonaldo & Brescovit, 1994, S. duidae Gertsch, 1942, S. roraimae Gertsch, 1942, S. peckorum Bonaldo & Brescovit, 1994, and S. archangelus Bonaldo & Brescovit, 1994 are supplied.
