Genus LANISTES Montfort, 1810

LANISTES Montfort, 1810: 122 . Type species: Lanistes olivierii Montfort, 1810 [as “ Oliverii ”, lapsus calami; = carinata Olivier, 1804 ], by original designation.

Remarks. Misspelled as “ Lanites ” by Swainson (1840: 339).

MELADOMUS Swainson, 1840: 340 . Type species: Meladomus bulimoides Swainson, 1840 [= Ampullaria purpurea Jonas, 1839 ], by monotypy.

Remarks. Gray (1847: 148), followed by G.B. Sowerby III (1916: 68), considered Paludina olivacea G.B. Sowerby I as the type species, although bulimoides Swainson was the only originally included species. Synonym of Lanistes Montfort , teste Berthold (1991: 201, 246).

LEROYA Grandidier, 1887: 191 . Type species: Leroya bourguignati Grandidier, 1887 [= farleri Craven, 1880 ], by subsequent designation of Pilsbry & Bequaert (1927: 199).

Remarks. Synonym of Lanistes Montfort , teste Berthold (1991: 201, 246).

BOLTENIANA Bourguignat, 1889: 178 [as section of Meladomus Swainson ]. Type species: Cyclostoma carinata Olivier, 1804 , by subsequent designation of Pilsbry & Bequaert (1927: 183).

Remarks. Synonym of Lanistes Montfort , teste Pilsbry & Bequaert (1927: 183).

LIBYCIANA Bourguignat, 1889: 176 [as section of Meladomus Swainson ]. Type species: Ampullaria libyca Morelet, 1848 , by subsequent designation of Pilsbry & Bequaert (1927: 183).

Remarks. Synonym of Lanistes Montfort , teste Pilsbry & Bequaert (1927: 183).

NYASSANA Bourguignat, 1889: 179 [as section of Meladomus Swainson ]. Type species: Lanistes nyassanus Dohrn, 1865 , by monotypy.

Remarks. Synonym of Lanistes Montfort , teste Pilsbry & Bequaert (1927: 183).

OLIVACEANA Bourguignat, 1889: 172 [as section of Meladomus Swainson ]. Type species: not designated.

PURPURIANA Bourguignat, 1889: 170 [as section of Meladomus Swainson ]. Type species: not designated.

PLESIOLANISTES Berthold, 1991: 210, 247. Type species: Helix varica Müller, 1774 , by monotypy. N. syn.

Pilsbry & Bequaert (1927) and Brown (1980, 1994) treated Meladomus Swainson , Leroya Grandidier and Lanistes s. str. as subgenera of Lanistes Montfort. However , all are here treated as synonyms of Lanistes Montfort , following Berthold (1991: 202), who considered that these subdivisions may not be valid and that the genus Lanistes be subdivided into only two subgenera, Lanistes s. str. and Lanistes subg. Plesiolanistes Berthold. Pilsbry & Bequaert (1927: 187) thought that Lanistes nyassanus Dohrn “seemingly belongs in a distinct group” but refrained from formally treating Nyassana Bourguignat as a valid subgenus. Plesiolanistes Berthold was erected on very little basis for a single species and is here treated as a synonym of Lanistes Montfort.

+ adansoni

Meladomus adansoni Kobelt, 1911: 18 , pl. 24, fig. 6. Type material — holotype [by monotypy]: SMF 7466. Type locality —“Senegambien” [ Senegal and Gambia]. Distribution — Senegal, Gambia, Democratic Republic of the Congo ( Pilsbry & Bequaert 1927: 196–197).

Remarks. The original description was explicitly based on a single shell that Kobelt had had in his possession for many years. The SMF shell matches the description well and is therefore considered the holotype by monotypy ( Code, Art. 73.1.2). Form of ovum Troschel , teste Boettger (1913: 106). Valid species, teste Pilsbry & Bequaert (1927: 196). Form of varica Müller , teste Brown (1980: 50, 1994: 60), followed here.

aegyptiaca

Ampullaria aegyptiaca Jickeli, 1874: 227 . Unavailable name: first published as a junior synonym of carinata Olivier ; not treated as an available name or adopted as the name of a taxon before 1961 ( Code, Art. 11.6).

Remarks. Name attributed to “Ehrenb. Mus. Berol” by Jickeli (1874: 227), apparently based only on labels associated with the shells (9 spms.) in Berlin (ZMB 13929; M. Glaubrecht pers. comm. 7 & 8 May 2013), as it seems not to have been published prior to this. Treated as a synonym of carinata Olivier by G.B. Sowerby III (1916: 65; as “ aegyptica ”) and Pilsbry & Bequaert (1927: 186).

affinis

Lanistes affinis Smith, 1878: 716 , pl. 74. fig. 7. Type material — syntype: NHMUK 1877.9.28.25 (1 spm., labelled “ type ” and “ holotype ”). Type locality —“Lake Nyassa” [in publication title].

Remarks. Variety of ovum Troschel , teste Kobelt (1909: 79, 1911: 12). Valid species, teste Pilsbry & Bequaert (1927: 194). Synonym of ovum Troschel and ellipticus Martens , teste G.B. Sowerby III (1916: 67) and Brown (1994: 63), respectively, followed here.

+ albersi

Meladomus ( Lanistes) libycus albersi Kobelt, 1912b: 25 , pl. 23, figs. 5, 6. Type material — holotype [by monotypy, the specimen figured as “ Lanistes libycus var .” by Martens (1866, pl. 70, figs. 5, 6)]: ZMB 109. Type locality —“ Gabon ”. Distribution —no additional information.
