Anolis aeneus is monotypic. • DIAGNOSIS . Anolis aeneus can be distinguished • DEFINITION . Anolis aeneus is a moderately sized from other Lesser Antillean anoles by the following anole (maximum known SVL in males to 77 mm on combination of characters (Schwartz and Henderson Grenada, and to 80 mm in Guyana; females to 55 1985): smooth ventral scales ( A. lividus and species mm; Schwartz and Henderson 1991). Loreal rows number 3–4, scales between supraorbitals 0, scales in the A. wattsi complex have keeled ventrals), mod - between interparietal and supraorbital semicircles 0, erate size ( A. ferreus, A. griseus, A. richardii, A. ocu - postrostrals 3–4, and postmentals 4–6.

The orbital area is bluish, though not in sharp contrast with dorsal ground color. The • DESCRIPTIONS . In addition to the original des- dewlap is a dull gray-green, with scales varying from criptions, detailed descriptions may be found in Lazell the same color to bright yellow and white. Ventral (1972), Schwartz and Henderson (1991), and Murphy scales are gray. The dorsum of females is gray brown (1997). 892.2 and Haberham (2003), FNPD (2006), Fläschendrä- ger and Wijffels (2009), and Quinn et al. (2010). Black -and -white photographs are in Gorman (1968) and Wijffels (1997). Gorman and Atkins (1968) pro - - - vided black and white photographs of meiosis and mitosis. • DISTRIBUTION . Anolis aeneus is endemic to Grenada and the Grenadines, and has been intro - duced to Trinidad and Guyana (Schwartz and Hen- derson 1991). Murphy (1997) listed known localities on Trinidad and nearby satellite islands, but the spe- cies was not known from Tobago (e.g., Mertens 1969, 1974) until 2008 (G. White in Hailey and Cazabon - Mannette 2011). The species is found in both mesic and xeric habitats at elevations ranging from sea level to the highest peaks on Grenada. On the Gre- Distribution of Anolis aeneus showing localities for MAP 1. nada Bank, these lizards are found in both natural introduced populations on Trinidad (adapted from Murphy and severely disturbed habitats (as long as some 1977) and the South American mainland. The box (see vegetative structure remains); in contrast, introduced Map 2 below) shows the Grenada Bank. populations appear to be restricted to urban and sub - urban areas. Parker (1933) listed six specimens in the British Museum from Barbados. Whether the locality data are erroneous, the specimens were incorrectly identi - fied, or a propagule of the species once existed on Barbados is unknown. • FOSSIL RECORD .
