Author Affiliations +

We provide here a catalogue of all available species nomina of Orthalicoidea occurring in Argentina. Ongoing taxonomic revisions on the genera Bostryx Troschel, 1847, Clessinia Doering, 1874, Pilsbrylia Hylton Scott, 1952, and Spixia Pilsbry & Vanatta, 1898, highlighted the necessity of an updated catalogue for the region. A total of 101 orthalicoidean species classified into four families, Bothriembryontidae, Bulimulidae, Odontostomidae and Simpulopsidae are present in Argentina. The catalogue provided here is based on examination of primary literature, available revisions and monographs, comparative studies within and among species and revision of museum data, including most type specimens. Additional collection of specimens in various localities of the country was carried out for more than a decade to be able to accurately state distributional information on the species treated. Nomenclatural details are provided for all nominal species. Name-bearing types were located for 86 species-group taxa, and six lectotypes were designated for the stabilization of the taxonomy. We propose the following nine new combinations: Bulimulus fourmiersi (d'Orbigny, 1835), Clessinia cordovana (Pfeiffer, 1855), Drymaeus flossdorfi (Holmberg, 1909), Cyclodontina (Ventanía) avellanedae (Doering, 1881), Simpulopsis (Eudioptus) eudioptus (Ihering in Pilsbry, 1897), Spixia champaquiana (Doering, 1875), S. charpentieri(Grateloup in Pfeiffer, 1850), S. minor (d'Orbigny, 1837) and S. parodizi (Hylton Scott, 1951). The following four new synonymies are proposed: Bostryx sophieae Breure, 1979, with Bulimus cordillerae (Strobel, 1874) (current name Bostryx cordillerae); Cyclodontina (Clessinia) gracilis Hylton Scott, 1956, with Bulimus cordovanus Pfeiffer, 1855 (current name Clessinia cordovana); Spixia estherae Fernández, 1971, with Odontostomus (Spixia) costellifer Hass, 1936 (current name Spixia costellifer); Kuschelenia simulans Hylton Scott, 1951, with Helix tupacii d'Orbigny, 1835 (current name Scutalus tupacii). Bulimulus sporadicus gracilis Hylton Scott, 1948, is changed from subspecific to specific status.
