Anolis alayoni is a cryptic species, and the fourth member of the twig ecomorph of Cuban Anolis. Morphological data suggest that its closest relative is the partly sympatric species A. angusticeps.
Diagnosis. —A small species (2 SVL 42.2 mm males; 36.6 mm females) of Anolis with short limbs, long snout, short semiprehen-sile tail, and enlarged scales on dorsal sur-face of head. Anolis alayoni is a member of the angusticeps species group of Anolis, which includes A. angusticeps, A. guazuma, and A. paternus. From A. guazuma, it can be distinguished by a tail longer than SVL (shorter in gua-zuma), 1-2 scales between supraorbital semicircles (modally 0 in guazuma), keeled head scales (smooth in guazuma), well-de-veloped yellow dewlap (small and whitish in guazuma), and other scale and pattern features. From A. paternus, it can be distin-guished by smooth ventral scales (keeled in paternus) and larger body size. From its closest relative, A. angusticeps, it can be distinguished by large size of the males (X SVL = 42.2 mm in alayoni; 39.9 mm in angusticeps) and the color of the dewlap: dark yellow in alayoni, pale orange or peach in angusticeps. Scale characters which can distinguish most A. alayoni from most A. angusticeps are: modally 11 (8-12) scales around the interparietal in males, 10 (9-13) in females of alayoni (modally 13 [11-16] in males, bimodally 13 and 14 [12- 15] in females of angusticeps); modally two [2-3] scales between naris and rostrum in alayoni (modally three [2-3] in angusticeps), modally four (3-5) scales between nares in alayoni (modally five [3–6] in angusticeps), modally 15 (13–16) lamellae under phalan-ges II and III of fourth toe in alayoni (mod-ally 13 [12-20] in angusticeps), modally four (2-6) postmarital scales in alayoni (modally six [4-7] in males, four [4-6] in females of angusticeps), bimodally 20 and 22 (18-28) middorsal scales in alayoni (bimodally 35 and 37 [26-37] in angusticeps). In combi-nation, these color, measurement and modal scale differences clearly distinguish all specimens of alayoni and angusticeps (from ESTRADA & HEDGES 1995).
