Confusion over the distributional ranges and the identity of the rissoids Onoba semicostata and O. aculeus has led to the latter being under-recorded. Systematic fieldwork over the last 10 years has shown that O. aculeus is widespread around the British Isles and on the northern coast of France. This paper gives additional information on the distribution, ecology and location of the Onoba species.
