Chiton (Mollusca: Polyplacophora) fauna of Barbados, West Indies, with the description of a new species
Abstract:Seventeen species of chitons, one new, have been found in Barbados, the easternmost island of the Lesser Antilles: Lepidochitona beanii (Carpenter, 1857), Ischnochiton striolatus (Gray, 1828), I. erythronotus (Adams, 1845), I. pseudovirgatus Kaas, 1972, I. bromleyi Ferreira, new species, Stenoplax limaciformis (Sowerby, 1832), S. boogii (Haddon, 1886), Ischnoplax pectinala (Sowerby, 1840), Ceratozona squalida (Adams, 1845), Chiton tuberculalus Linnaeus, 1758, C. marmoratus Gmelin, 1791, C. viridis Spengler, 1797, Tonicia schrammi (Shuttleworth, 1853), Acanthopleura granulata (Gmelin, 1791), Acanlhochitona astrigera (Reeve, 1847), A. rhodea (Pilsbry, 1893), and Choneplax cf. C. lata (Guilding, 1829). One of these species, I. bromleyi, is endemic; four, I. striolatus, S. limaciformis, S. boogii, I. pectinata, range southward to Brazil; five, L. beanii, S. limaciformis, S. boogii, C. squalida, A. rhodea, occur in both Caribbean and tropical eastern Pacific. Some significant taxonomic changes are proposed: Ischnoplax is elevated to generic level; Ischnochiton boogii is allocated to Stenoplax; Lepidochitona liozonis and L. rosea are regarded as junior synonyms of L. beanii; Acanthochitona hemphilli is regarded as junior synonym of A. rhodea; Acanthochitona elongata, A. interfissa and A. andersoni are regarded as synonyms of Choneplax lata.
