Onchidium is a genus of air-breathing sea slugs, shell-less marine pulmonate gastropod mollusks in the family Onchidiidae.

Species

Some authors recognize only four species in the genus.[2][3] The World Register of Marine Species lists six species as accepted.[4]

• Onchidium melakense Dayrat & Goulding, 2019[2]
• Onchidium multiradiatum C. Semper, 1882
• Onchidium nebulosum C. Semper, 1880
• Onchidium reevesii (J. E. Gray, 1850)[3]
• Onchidium stuxbergi (Westerlund, 1883)[3]
• Onchidium typhae Buchannan, 1800[3]

Onchidium multinotatum, originally described within the genus in 1883, is regarded as a nomen dubium.[5]
