Revision of the genera of Scolodontidae, part 4: Miradiscops H.B. Baker, 1925 and Mayadiscops gen. nov.

The revision of the genera of Scolodontidae by our team continues, reaching its fourth instalment. In this paper, the species traditionally included in Miradiscops H.B. Baker, 1925 are discussed. Miradiscops is retained for all species with a pitted protoconch and pitted teleoconch sculpture and discoid shells with a wide umbilicus. Species with a striate teleoconch sculpture, smooth protoconch, and more lenticular shell with a narrower umbilicus are classified in Mayadiscops gen. nov. The type material of all species allocated to these two genera are figured here to assist future studies. Some species formerly assigned to Miradiscops are here reclassified into other Scolodontidae genera. The following new combinations are made: Scolodonta andivaga Pilsbry, 1932; Mayadiscops balboa (Pilsbry, 1930) comb. nov.; Tamayoa (Tamayops) bladenensis (D.S. Dourson, Caldwell & J.A. Dourson, 2018) comb. nov.; Scolodonta florezi (Weyrauch, 1967) comb. nov.; Mayadiscops hovestadti (van Leeuwen & Salvador, 2024) comb. nov.; Tamayoa (Tamayops) implicans (Guppy, 1868) comb. nov.; Mayadiscops maya (Pilsbry, 1920) comb. nov.; Mayadiscops opal (Pilsbry, 1920) comb. nov.; Mayadiscops ridiculus (Pilsbry, 1930) comb. nov. Finally, Miradiscops striatae D.S. Dourson, Caldwell & J.A. Dourson, 2018 is considered a junior synonym of Mayadiscops maya comb. nov.
