History.— Summer 1967: members of the Cuban-German Expedition (Universidad de La Habana & Institut für Paläontologie und Museum der Humboldt-Universität zu Berlin) collect the type material in western Cuba ( Castellanos 1968: 4, Fischer 1968: 270, 1970). 1971: original description of Fulica picapicensis published ( Fischer & Stephan 1971b: 595–597). 31 December 1974: Antillean extinct genus Nesotrochis identified from Cuba, leading to the new combination N. picapicensis ( Olson 1974: 441, see ‘Notes’). September 1995: first record outside the type locality, in Cueva del Indio, Mayabeque (formerly La Habana) province ( Jiménez Vázquez & Valdés Ruiz 1995: 62). 27 August 2019: morphology of the hypotarsus in Nesotrochis indicates it is not a Rallidae ( Mayr 2019) , but shares osteological characters with flufftails, Sarothruridae (Africa and New Guinea) and related taxa ( Heliornithidae ). 17 March 2021: mitochondrial genome analysis of N. steganinos Olson, 1974 (Hispaniola) corroborates that the genus is not a rallid ( Oswald et al. 2021), but a sister taxon to Sarothruridae and the extinct flightless Aptornithidae ( New Zealand).

Holotype.—Left humerus, Av. 832/67, at CZACC ( Fischer & Stephan 1971b: 595, fig. 9: a [anconal], b [palmar], Olson 1977: 352, fig. 1b: bottom [anconal]). Collected summer 1967 by members of the Cuban-German Expedition [= Wolfgang Reichel, Hans-Hartmat Krueger, Karlheinz Fischer, Gustavo Furrazola Bermúdez, Manuel Acevedo González, Néstor Mayo and Manuel Iturralde Vinent ( Castellanos 1968: 4)] in El Abismo [= Furnia del Aguacero, or del Abismo] at the type locality (see Fischer & Stephan 1971a: 541, b: 593).

Notes.—Bones of this cave rail are common in palaeontological deposits of western Cuba and are abundant in cultural (contra Steadman et al. 2013: 1355) sites (see Jiménez Vázquez 1997b, 2001, Jiménez Vázquez & Arrazcaeta Delgado 2008, 2015). Formerly described as a coot, genus Fulica Linnaeus. One of the paratypes, the incomplete right ulna, Av. 843/67 ( Fischer & Stephan 1971b: 595, fig. 10a [medial]), ‘is not from a rail and is possibly columbid’ ( Olson 1974: 441, footnote). The extinct genus Nesotrochis is endemic to the Greater Antilles but has Old World origins ( Oswald et al. 2021). Three large flightless species (Olson 1977: 352–353, Olson 1978: 107, Cuello 1988: 15; see Livezey 1998) have been described, from the Virgin Islands ( N. debooyi Wetmore, 1918 ), but also present in Puerto Rico ( Wetmore 1922, Olson 1974), Hispaniola ( N. steganinos [= M. sterganinos Arredondo 1984: 15 , lapsus calami]) and Cuba ( N. picapicensis ), and seem to have survived on these islands until recently ( Olson 1974, Jiménez Vázquez & Arrazcaeta Delgado 2008, 2015, Carlson & Steadman 2009). The Cuban species was for some time considered the same bird named ‘Biaya’ or ‘Bambiaya’ by native peoples (cf. Jiménez Vázquez 1997b, 2005), but this is incorrect ( Jiménez Vázquez & Arrazcaeta Delgado 2015: 144). Figueredo (2011: 13) commented that the distribution of Nesotrochis could be extended to the Bahamas, citing Steadman et al. (2007). This appears to be a misinterpretation, as the only flightless rail mentioned in the latter paper (see also Steadman et al. 2013) is ‘ Rallus undescribed sp.’. For a summary of extinct birds in Quaternary deposits of the Bahamas, see Steadman & Franklin (2020).
