[4] K. herrerai is found in the Mexican states of Hidalgo, Puebla, San Luis Potosí, Tamaulipas, and Veracruz.

[3] The preferred natural habitat of K. herrerai is permanent bodies of fresh water, at elevations from sea level to 1,150 m (3,770 ft).

[1] Based on a 1988 study of a population near Rancho Nuevo in Tamaulipas, Mexico, the males of K. herrerai attain a larger size than females, with a proportionally smaller plastron, and narrower and shallower carapace.

[5] Symbionts reported include a balanomorph barnacle, leeches of the genus Placobdella, and the filamentous green alga Basicladia.

[5] Food items identified indicate an omnivorous diet, with wild figs the major plant component, and several insect orders and millipedes represented.
