DistributionW/C Cuba, Isla de la Juventud; Hispaniola, Haiti
USA (introduced to Florida, Key West Islands)

elegans: Cuba, Isla de la Juventud; associated cayertas; introduced on Florida Keys; Type locality: Cuba; probably the vicinity of Guanabacoa, La Habana Province, Cuba, according to Barbour, 1921.

punctatissimus: Hispaniola; Île Grande Cayemite; Île de la Gonâve.  
Reproductionoviparous 
TypesHolotype: Unlocated.
Syntypes: MNHN-RA 1768, MNHN-RA 1768A-B [punctatissimus]
Syntype: USNM 52407 [Sphaerodactylus alopex] 
DiagnosisDESCRIPTION: Size moderate (SVL in males to 39 mm, in females to 37 mm); dorsals small, slightly swollen, slightly keeled, weakly imbricate, axilla to groin 41-59; no area of middorsal granules or granular scales; ventrals smooth, cycloid, imbricate, axilla to groin 24-45; dorsal caudal scales smooth, cycloid, imbricate, ventral caudal scales smooth, cycloid, imbricate, enlarged midventrally; snout acuminate, not depressed or decurved; snout scales granular, enlarged, flattened; 1 postnasal; 0-2 (strongly modally 1) internasals; upper labials to mideye 3-5 (strongly modally 4); gular scales smooth; chest scales smooth; midbody scales 49-84; escutcheon 4-8 x 19-37. Adults not strongly sexually dichromatic, but strong ontogenetic pattern change; juveniles (SVL 20-28 mm and below, by subspecies) yellowish to reddish dorsally with prominent reddish tail and limbs; body and tail transversely banded with dark brown to almost black, this boldly contrasting pattern gradually changing to (adults) dark brown, pale tan, yellowish tan dorsum, either speckled with many isolated pale whitish to very pale tan scales or not, isolated pale scales at times confluent on body to give vague, fine, longi-
tudinal striate effect; head in both sexes either concolor with dorsum, dotted with minute, pale flecks, or (full adults) strongly streaked or vermiculate with pale tan and dark brown: throat (males) finely stippled or coarsely vermiculate with brown (by population); iris golden to golden yellow (from Schwartz & Henderson 1991: 491). 
CommentSynonymy: S. punctatissimus has been downgraded to S. e. punctatissimus by Schwartz & Garrido (1985). Grant (1948) demonstrated conclusively that elegans and cinereus are actually ontogenetic forms of the same species. However, Mittleman 1950 concluded that they are taxonomically distinct.
