Remarks

This taxon was initially introduced as a subspecies of A. damottai distributed in Maio Island. There are clear morphological similarities in shell pattern and radular tooth. However, the phylogenetic analysis indicates that A. galeao is actually a separate species, whose lineage diverged from that of A. damottai in the middle Pliocene. It is sister to A. calhetae , a parapatric valid species from Maio Island, which had been also initially introduced as a subspecies of A. navarroi . There is a number of morphs of A. galeao with distinctive shell patterns (i.e., reticulated, greenish, etc.) corresponding to well-defined populations from different bays in northern Maio Island, but all these have shown to be conspecific. Among these, A. claudiae from Praia Real is a color form of A. galeao . This must not be confused with another color variation of A. calhetae found in the west coast of Maio Island, which also resembles phenotypically the A. galeao form claudiae .
