Lucilina Dall 1882

Genus Lucilina Dall, 1882 Type species. Chiton confossus Gould, 1846 (= Chiton lamellosus Quoy & Gaimard, 1835), by subsequent designation (Pilsbry 1893). Remarks. Following the suggestions of some authors (e.g., Strack 2003; Schwabe 2004, 2006; Schwabe et al. 2008; Schwabe & Pittman 2014), the genus Lucilina is here used at full genus level, and not as a subgenus of Tonicia Gray, 1847. The species of Tonicia are geographically restricted to the South Eastern Pacific region of Latin America with a single species in the Caribbean, while members of Lucilina are widespread throughout the tropical Indo-Pacific. Lucilina is well represented in the Indian Ocean by six species, L. sueziensis (Reeve, 1847), L. perligera Thiele, 1909, L. pectinoides (Sykes, 1903), L. ceylonica (Leloup, 1936), L. carnosa (Kaas, 1979) and L. indica (Leloup, 1981), of which only the first two are known from the Red Sea. Distribution. Widespread in the Indian Ocean, the Indo-Pacific, Australia, the Central Pacific Ocean and Japan. The fossil record extends back to the middle Oligocene of France, Aquitaine Basin (Dell’Angelo et al. 2018a), the Neogene of west Pacific islands (Ladd 1966; Schwabe et al. 2008) and the Pleistocene of the Red Sea (Issel 1869).
