Deep-sea chitons from sunken wood in the West Pacific (Mollusca: Polyplacophora: Lepidopleurida): taxonomy, distribution, and seven new species Author Sigwart, Julia D. Author Sirenko, Boris I. text Zootaxa 2012 3195 1 38 journal article 45430 10.5281/zenodo.280094 bb00c6b5-4487-466c-bb24-0189eb04f31f 1175-5326 280094 Leptochiton foresti ( Leloup, 1981 ) Lepidopleura [sic] foresti Leloup 1981 : 321 , text fig. 2, pl. 2, figs 7–10. Leptochiton foresti : Kaas 1982 : 88 ; Kaas & Van Belle 1985 : 122 –124, fig. 54, map 44; Sigwart 2008a : tables 1–2, fig. 2B; Sigwart et al. 2011: 567, table 3, fig. 2. Material examined. Holotype ( MNHN 5878) and 4 paratypes ( MNHN 5945, 5946, 5950, 5951). 56 specimens in 13 lots from the Philippines . Distribution. Philippines , known from the region 9–14° N, 120–123° E, generally found in 137–484 m (summarised in Kaas & Van Belle 1985 ). Two new records reported here are from deeper waters, 982–989 m (Panglao 2005 sta. CP2385) and the deepest record for the species, 1764 m (Panglao 2005 sta. CP2356). Remarks. This species has perhaps the most distinctive and easily identified sculpture of any of the South Pacific Leptochiton spp., with around 50 well-separated longitudinal rows of round granules on the central area of intermediate valves and radiating chains of flatter granules on the lateral areas (see Kaas & Van Belle 1985 : fig. 54). Kaas & Van Belle (1985) erroneously reported that L. foresti has 16–18 gills per side. The species consistently has 10 gills per side in adult specimens, confirmed here by re-examination of the type series.
