Genus Netastoma Carpenter, 1864

[= Netastomella Paetel, 1875 (error pro Nettastomella Carpenter, 1865 ); Nettastoma Lamy, 1926 (error pro Netastoma Carpenter, 1864 ); Nettastomella Carpenter, 1865 ; Nettostomella Habe, 1952: 244 (error pro Nettastomella Carpenter, 1865 )].

Type species: Pholas darwinii G. B. Sowerby II, 1849 , by monotypy.

Distribution: Japan and east Pacific coast from USA to southern Chile and Southwestern Atlantic Ocean.

Remarks: The genus Netastoma was described by Carpenter (1864) who proposed as a type species Pholas darwinii . A year later Carpenter (1865) proposed Nettastomella as replacement name of Netastoma to emend the homonymy with Nettastoma Rafinesque, 1810 (Pisces, Anguiliformes). In this way, the name Nettastomella has been used by several authors ( Turner 1969; Kennedy 1974 among others). Turner (1955) examined Carpenter’s collection and confirmed that type species designation was based on a misidentification of N. rostratum . Additionally, Carpenter diagnosis and locality fit more adequately to N. rostratum than to N. darwinii . Coan and Kennedy (1980) elevated to the ICZN the revision of Nettastomella and the designation of the type species. Finally, the ICZN (Opinion 1296 1985) concluded that the generic name Netastoma must be considered as valid with type species Pholas darwinii G. B. Sowerby II, 1849 , by monotypy. Currently, the genus Netastoma includes three species: Netastoma darwinii (GB Sowerby II, 1849) , Netastoma rostratum ( Valenciennes, 1846) and Netastoma japonicum ( Yokoyama, 1920) .
