Genus Liloa Pilsbry, 1921

Type species: Bulla curta Adams, 1850

Pilsbry (1921) introduced Liloa as a subgenus of Haminoeidae with type species Haminoea curta tomaculum Pilsbry, 1917 . According to Pilsbry (1917), this species has a narrower shell compared to Bulla curta described by Adams (1850). Habe (1952) considered both species to be synonyms and gave Liloa genus status in the family Haminoeidae . Pilsbry (1921) stated that species of the genus Liloa possess narrow shells with spiral grooves throughout but some authors claimed that some species only have spiral grooves at the ends of the shell ( Habe 1952; Lin 1997; Rudman 1998a; Qi 2004). Species recognized in the Indo-West Pacific include L. curta ( Adams, 1850) , L. brevis ( Quoy & Gaimard, 1833) , L. porcellana ( Gould, 1859) , L. translucens ( Adams, 1862) , L. incisula Yokoyama, 1928 and L. nipponensis ( Nomura & Hatai, 1940) ( Burn 1978; Lin 1997; Gosliner et al. 2008; OBIS 2012b) (see Tab. 4 for diagnostic characters of species described here).
