• Hymenosoma crosnieri Naruse & Guinot, 2023
• Hymenosoma depressum Hombron & Jacquinot, 1846
• Hymenosoma gaudichaudii Guérin, 1831
• Hymenosoma geometricum Stimpson, 1858
• Hymenosoma hodgkini Lucas, 1980
• Hymenosoma longicrure Dawson & Griffiths, 2012
• Hymenosoma lurio Poore, Jaime & Teske, 2025
