Figures 1-3. 1 in New relevant records for the Cuban Giant Whipscorpion: Mastigoproctus santiago Teruel, 2010 (Thelyphonida: Thelyphonidae)

Figures 1-3. 1 Maps of Cuba (a) and southern coast of Santiago de Cuba province (b, a close-up of the small inset in previous figure), showing updated distribution of Mastigoproctus santiago: previous records (red dots) and new records (yellow dots, Peñas Altas at extreme west and Sigua at extreme east). 2 New specimens of Mastigoproctus santiago, photographed alive: adult male from Sigua (a), subadult female from Sigua (b) and adult female from Peñas Altas (c). Note that flagellum is missing in specimen "b", in specimens "a" and "c" it is complete but off-frame. Scale bar in centimeters, with millimeter subdivisions. 3 Habitat and microhabitat of Mastigoproctus santiago at the two new localities herein recorded: Sigua, desert scrub (a) and exact cave room where specimens were found (b), Peñas Altas, dry semicaducifolious forest (c).
