Argonemertes dendyi

Argonemertes dendyi was originally classified in the genus Geonemertes by William John Dakin. Dakin discovered and described the new species when he was searching for velvet worms in Western Australia's Darling Scarp.^[2]: 567

A. dendyi belongs to the suborder Monostilifera, a clade defined having just one stylet – a small hard spine in their proboscis.^[3]

Argonemertes dendyi is believed to originate from Australia (where it was first described), but has been found in the British Isles, the Azores, the Canary Islands, California, Hawaii, Europe, and the North Island of New Zealand.^{[4]: 141 [5]: 66}
