American Mud and Musk Turtles
32 species of which 17 (53.1%) are endemic -
4 genera of which none are endemic
(as of December 31st, 2018).
Includes two subfamilies (Kinosterninae, Staurotypinae), which were separated and raised to family status by Iverson, Le & Ingram (2013),
although some authors had already regarded them as such
(e.g., Bickham & Carr 1983; King & Burke 1989; Vetter 2005; Casas-Andreu, Mendez-de la Cruz & Aguilar-Miguel 2004).
This taxonomy has not been met with general acceptance, so the traditional classification as a single family with two subfamilies is retained herein, following several
subsequent works (e.g., Vitt & Caldwell 2014; Crawford, Parham, Sellas, Faircloth, Glenn, Papenfuss, Henderson, Hansen & Simison 2015;
Rhodin, Iverson, Bour, Fritz, Georges, Shaffer & Dijk 2017; Shaffer, McCartney-Melstad, Near, Mount & Spinks 2017).
