Tarsometatarsus: proximal right, MNHNCu 75.4656; distal right, MNHNCu 75.4652 (fig. 7F [anterior]); proximal left without inner calcaneal ridge, MNHNCu 75.4655 (fig. 7: C [anterior]), H [proximal]); distal left, MNHNCu 75.4657 (fig. 7: G [anterior], I [distal]). Cited material and figures from Suárez & Olson (2020a).

Type locality.—Las Breas de San Felipe ( MLB), c. 5.5 km west of the town of Martí, San Felipe Valley, municipality of Martí, Matanzas province, Cuba ( Suárez & Olson 2020a: 552; for description of this deposit see Iturralde-Vinent et al. 2000). Fig. 5 .

Distribution.—Cave and asphalt deposits in west Cuba (see Appendix). Pinar del Río. Los Palacios: PEA ( Suárez & Díaz-Franco 2003: 375 [‘small, undescribed species of Tyto ’], Suárez 2004b: 156 [‘a new species of Tyto ’], Suárez & Olson 2020a: 556 [but not ‘municipality of La Palma’]). Artemisa. Caimito: ACP ( Suárez & Olson 2020a: 556). Matanzas. Martí: MLB = type locality ( Suárez & Olson 2020a: 552 [‘ Tyto maniola , new species’]).

Direct 14 C dating .—None. For dating of other bird species at the type locality, see Antigone cubensis , Gymnogyps varonai and Ornimegalonyx oteroi , and of associated extinct mammals ( Parocnus browni = 11,880 ± 420 to 4,960 ± 280 years 14 C BP), see Jull et al. (2004) and Steadman et al. (2005). For dating of associated fauna at PEA ( Tyto noeli ), see Suárez & Díaz-Franco (2003: 373).

Notes.—Uncommon, currently unknown from sinkhole deposits. The smallest Cuban tytonid, living or extinct, being also smaller when compared to skeletal elements of Ashyfaced Owl T. glaucops ( Kaup, 1852) —and its synonym T. cavatica Wetmore, 1920 —of Hispaniola ( Suárez & Olson 2020a: 556).
