Remarks

The Madibenthos material matches with the descriptions in Child (1992b) and Müller & Krapp (2009) of Anoplodactylus californicus for most characters. Instead of lateral processes with rounded tubercles, as represented in Child’s and Müller & Krapp’s specimens, Madibenthos specimens show distal angular thickening. Anoplodactylus califorinicus was already recorded in Martinique (as A. carvalhoi ) by Bourdillon (1955) and Müller (1990a), but Bourdillon’s illustrations show differences from the Madibenthos material. For example, the ocular tubercle is somehow lanceolate (narrower at the base, broader at mid-length, with tapering tip) in the Madibenthos material, while it is represented as conical by Bourdillon. We note that the ocular tubercle shape is highly variable in the illustrations of different authors, more or less tapering, conical or rounded (e.g., Hall 1912; Child 1992b; Müller & Krapp 2009; Weis & Melzer 2012). Regarding molecular data, p-distances from some previously sequenced material from the Colombian Caribbean identified as A. californicus (GenBank reference DQ390068 View Materials ; Arango & Wheeler 2007) are relatively low (0.047). Therefore, a revision of this widespread and multisynonymised species is needed. Until then, we only allegedly link Madibenthos material to this species as Anoplodactylus cf. californicus .

Distribution

Recorded in the Eastern Pacific (California, Ecuador, Mexico, Chile, Costa Rica, Nicaragua, Panama) and in Hawaii and the Panama Canal. It is also often recorded in the Caribbean Sea ( Belize, Caribbean Panama, Bahamas, Martinique, Colombia, Costa Rica, Curaçao, Bonaire, Saint Kitts and Nevis, Virgin Islands, Porto Rico), the Gulf of Mexico and the Western Atlantic in Brazil and Argentina southward to the Magellan Strait. It is also recorded from the Mediterranean, in the Thyrrenean and Levantine Seas, as well as in the Suez Canal.

Depth range

Intertidal– 100 m.
