The group is represented by <i>Eucallista</i> Dall, <a href="#CIT0031" target="_blank">1902</a> (early Miocene–Recent), <i>Austrocallista</i> Erdmann & Morra, <a href="#CIT0045" target="_blank">1985</a> (Eocene–Pliocene) and <i>Proteopitar</i> gen. nov. (middle Miocene–Recent). <i>Eucallista</i> and <i>Austrocallista</i> have sculptured nymphs and include species previously assigned to <i>Amiantis</i> Carpenter, <a href="#CIT0017" target="_blank">1864</a>. <i>Eucallista</i> is represented by three species: the extant <i>E. purpurata</i> (Lamarck, <a href="#CIT0085" target="_blank">1818</a>) (Pleistocene–Recent, South-Western Atlantic Ocean from Golfo San Matías [Argentina] to Espirito Santo [Brazil]) and two fossil taxa, <i>E. laziarina</i> (Ihering, <a href="#CIT0079" target="_blank">1907</a>) from the Miocene and Pliocene of Chile, Argentina and Uruguay, and <i>E. domeykoana</i> (Philippi, <a href="#CIT0113" target="_blank">1887</a>) from the Miocene and Pliocene of Chile and Peru. <i>Austrocallista</i> has four taxa: <i>Austrocallista</i> sp. from the Eocene of Santa Cruz Province, <i>A. iheringi</i> (Cossmann, <a href="#CIT0028" target="_blank">1898</a>) from the late Oligocene–middle Miocene of Patagonia, <i>A. australis</i> (Feruglio, <a href="#CIT0048" target="_blank">1935</a>) (lectotype MGGC 607) from the early Miocene of Santa Cruz Province, and <i>A. boliviana</i> (Philippi, <a href="#CIT0113" target="_blank">1887</a>) from the Miocene and Pliocene of Chile and Peru. <i>Proteopitar</i> gen. nov. is erected to incorporate two species previously assigned to <i>Pitar</i> Römer, <a href="#CIT0123" target="_blank">1857</a>: <i>Proteopitar mutabilis</i> (del Río & Martínez, <a href="#CIT0036" target="_blank">1998</a>) from the middle Miocene–late Miocene of Argentina and the Pleistocene–Recent species <i>Proteopitar patagonicus</i> (d’Orbigny, <a href="#CIT0040" target="_blank">1835–1847</a>) (from Rio de Janeiro [Brazil] to Bahía Vera [Chubut, Argentina]). These systematic hypotheses are corroborated by the phylogenetic analysis performed, which is the first one of the subfamily that includes fossil and extant taxa based on morphological characters of the shell. In addition, a new site on the coast of Río Negro Province which contains shells of the extant species is dated as 830 Ka BP (MIS21), being the oldest record of both extant species.</p> <p><a href="http://www.zoobank.org/urn:lsid:zoobank.org:pub:16519263-4F9E-41AB-A009-EAC030681826" target="_blank">http://www.zoobank.org/urn:lsid:zoobank.org:pub:16519263-4F9E-41AB-A009-EAC030681826</a></p>
