Note  Status: Lessios et al. (2012: p. 140) state that: "There seems to be little doubt that A. crassispina and A. dufresni are not separate species, as the two morphs are not distinct in the phylogeny of either the mitochondrial or the nuclear gene. The morphological differences between the two nominal species are so slight, that Clark (1925) questioned whether they could be maintained as separate species. Mortensen (1935 [p. 580]), the author of A. crassispina, agreed that it may be a local variety of A. dufresni, but then changed his mind (Mortensen 1941 [p. 7-8])." Although Lessios et al. (2012) do not formally synonymize the two species, the evidence presented for the identity of the two taxa seems very strong and they are thus treated as synonyms here.
