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).
