DistributionAnguilla, St.-Barthélémy, St.-Martin, Tintamarre I., Dog. I., St. Barts.

TypesHolotype: UF/FSM 10034.1, adult male (Florida State Museum of Natural History) 
CommentSphaerodactylus parvus differs from most populations of S. macrolepis in having only hairbearing organs on the dorsal scales, in being much smaller, and in having a higher mean number of midbody scale rows (the range of the latter does not overlap with those known for five of the nine subspecies of S. macrolepis; see Table 1 in POWELL & HENDERSON 2001). Differences in pattern also exist, but “the lack of marked sexual dichromatism in parvus is of itself definitive” (Thomas and Schwartz, 1966). 
EtymologyNamed after Latin “parvus, -a, -um” = small.
