Based on morphological and molecular evidence (Livezey 2010, Černý and Natale 2022), Pied Lapwing Vanellus cayanus is not closely related to lapwings, or to any other genus of plover. Its name is thus changed to Pied Plover Hoploxypterus cayanus, without necessarily implying close relationships to any of the disparate groups called plovers, and aligns with Gill and Wright (2006, IOC v.1.0).
