Taxonomic note. The holotypes of A. abrolhos- ensis and A. gomezi were re-examined and found to be similar in the above characters. The entry for A. abrolhosensis in Veron, 2000: 256 includes a field photograph of A. pulchra (fig. 2) and appears to cover features that do not fit the original type description.
