Etymology: Allotoca: Greek, allos = other + Greek, tokos = birth (Ref. 45335). The transliterated Latin terminal part of the compound name ('tocus') was changed to 'toca', thus the genus is feminine (Ref. 35111); zacapuensis: Named for its known distribution, the basin Lagoon de Zacapu (Ref. 42981).
