Sphaerodactylus grandisquamis Stejneger, 1904

All populations of the S. macrolepis complex occurring on Puerto Rico and its satellite islands (e.g. Piñeros) are restricted to this taxon. S. grandisquamis was originally described by Stegneger (1904) and was reaffirmed as a valid taxon by Grant (1932c) but referred to as a subspecies of S. macrolepis s.l. by Thomas & Schwartz (1966). This taxon may include several undescribed species and in this paper we keep most of the subspecific names from Thomas & Schwartz (1966). Additional study is needed to better resolve the relationships among these subspecies, but at the moment we highlight the monophyly of this taxon, which is comprised of the subspecies: S. g. grandisquamis , S. g. guarionex, S. g. ateles, S. g. mimetes, S. g. spanius, and S. g. stibarus (S. g. phoberus was not supported by either molecular [this study] or morphological data [ Padilla, 2006] and is thus synonomized with S. g. grandisquamis ).

General traits of Sphaerodactylus grandisquamis . Compared to other members of the S. macrolepis complex, S. grandisquamis males have a higher number of escutcheon scales (67–95); males with dorsal stippled lines (except in S. g. mimetes); males exhibit a cephalic figure; males have a light line behind the eye; females with dorsal medial lines separated (except in S. stibarus where it forms a blotch or imperfect line); and a long and narrow snout (except in S. stibarus ).
