27. † Bubo osvaldoi Arredondo & Olson, 1994

Osvaldo’s Owl (Búho de Osvaldo) Bubo osvaldoi Arredondo & Olson, 1994 (part), Proc. Biol. Soc. Wash. 107: 438. Tyto riveroi : Salgado et al. 1992: 28, table 1.

History.— July 1991: holotype collected by O. Jiménez Vázquez and C. Morales in a cave deposit at Sierra de Galeras , western Cuba (see ‘Holotype’) . 4 October 1994: original description published ( Arredondo & Olson 1994). 9 December 2020: type series of B. osvaldoi revealed to be composite, and only specimens from the type locality represent this species ( Suárez 2020b).

Holotype.—Right tarsometatarsus lacking proximal end above tubercle for tibialis anticus, MNHNCu 75.27, formerly MNHNCu-27.1 ( Arredondo & Olson 1994: 438, fig. 1: B [posterior], C [anterior], D [distal], Orihuela 2019: 63, fig. 5: A [anterior], B [posterior]). Collected on 2 July 1991 (no collecting date appears in the original description, but was not ‘1992’ as reported in Díaz-Franco 2004: 156 and Herrera-Uria et al. 2015: 113) by Osvaldo Jiménez Vázquez and Carlos Morales at ‘Pozo del Búho’, in the type locality (O. Jiménez Vázquez in litt. 2021).

Other material.— Femur: right lacking internal condyle and abraded about the trochanter, MNHNCu 75. 4908, formerly MNHNCu 27.3 ( Arredondo & Olson 1994: 38, fig. 2: B [anterior], Suárez 2020b, fig. 1: D [anterior]). Tarsometatarsus: shaft of left, MNHNCu 75.4907, formerly MNHNCu 27.2. For discussion of incorrect data concerning the type series, see ‘Notes’.

Type locality.—Cueva del Mono Fósil ( PMF), Sierra de Galeras, municipality of Viñales, Pinar del Río province, Cuba ( Arredondo & Olson 1994: 438; see Rivero & Arredondo 1991, Salgado et al. 1992, Arredondo & Rivero 1997). Fig. 8 View Figure 8 .

Distribution.—Cave deposit in west Cuba (see Appendix). Pinar del Río. Viñales: PMF ( Arredondo & Olson 1994: 438).

Direct 14 C dating .—None.

Notes.—Extremely rare, unknown away from the type locality. The type series of B. osvaldoi was a composite, including two fossil bones from eastern Cuba that belong to another large strigid, Ornimegalonyx ewingi Suárez , of about the same size ( Suárez 2020b: 391). The catalogue numbers ‘MNHNCu P4607’ and ‘MNHNCu P4608’, assigned by Díaz-Franco (2004: 156), replicated by Herrera-Uria et al. (2015: 114), represent a lapsus calami (= the digit 9 was substituted by digit 6 on both specimens; S. Díaz-Franco & WS pers. obs.), maintained until today. Both numbers are in use for another taxon in the same collection ( Suárez & Olson 2003b: 73). In addition, incorrect data concerning the collection date and collector of the paratype femur (MNHNCu 75. 4908) was also republished ( Herrera-Uria et al. 2015: 114). The femur was secured at Cueva Alta, in the type locality, by other members (names unknown) of GEPAB, on a different (unknown) date to both tarsometatarsi (O. Jiménez Vázquez in litt. 2021).
