An attempt to identify an Acicula from Gibraltar not only lead to the conclusion that it was an undescribed species, but also to the discovery that A. (A.) lallemanti (Bourguignat) from Algeria included two distinct species. A. (A.) lallemanti is restricted by definition of a lectotype and is described together with A. (A.) algerensis nov. and A. (A.) norrisi nov. from Gibraltar. All three species are figured with A. (A.) lineata and A. (A.) sublineata for comparison.
