A specimen of Onchidium stuxbergi was found in Singapore (in the mangrove by the Mandai River) but was unfortunately lost. The presence of Onchidium stuxbergi was also documented (as Onchidium nigram, which is a spelling mistake) in a guide to the mangroves of Singapore (Ng and Sivasothi 2002: 115). The type locality of Onchidium nigrum simply was cited as " Borneo, " which could be anywhere on the island in Indonesia (Kalimantan) or Malaysia (Sabah or Sarawak). Our record in Macau is the northernmost (22 ° 10 ' N) confirmed locality on the coast of southern China.	en	Dayrat, Benoit, Goulding, Tricia C., Apte, Deepak, Bhave, Vishal, Joseph Comendador,, Qua, ng, Ngo Xuan, Tan, Siong Kiat, Tan, Shau Hwai (2016): Integrative taxonomy of the genus Onchidium Buchannan, 1800 (Mollusca, Gastropoda, Pulmonata, Onchidiidae).
