Scale bar = 5 mm. presacral vertebrae; pelvis with large and ventrally directed pectineal process; digits short, with manual metacarpals twice the length of the phalanges; fourth phalangeal element of the fourth manual digit short. Gular and body laterodorsal scales small, rounded posteriorly, and juxtaposed to weak- ly imbricate; some lateral scales distinctly keeled; forelimb scales smooth and strongly imbricate; claw enclosed by three scales. Ninety-nine extant and one fossil species of Sphaerodactylus are currently recognized as valid (Bohme, 1984; Kluge, 2001; Uetz, 2011). In general, Sphaerodactylus are known as endemics of small areas (Schwartz and Henderson, 1991; Henderson and Powell, 2009); because of this it is reason- able to compare this fossil with the 35 extant species from Hispaniola, as well as the other fossil species. However, because the age of the Dominican amber deposits is older than, or contemporaneous with, estimations of the formation of the Mona Passage and the separation of Hispaniola and Puerto Rico (-16-11 MYA; Iturralde- Vinent and MacPhee, 1996; MacPhee et al., 2003) we also compared the. new species with 10 extant s
