Enyalius

E. bibronii

Bibron's Fat-Head Anole

E Brazil

SVL 10 cm

Distinguished from E. catenatus in the following points: all the scales a little larger, ventrals smooth or very obtusely keeled. Limbs shorter; tibia nearly as long as the head; the adpressed hind limb reaches the posterior corner of the eye. [SOURCE: Boulenger]

E. catenatus

Wied's Fat-Headed Anole

E Brazil

TL approx 29.5 cm, SVL approx 9.5 cm (m), 10.5 cm (f)

Found in the forests of the coastal mountains, in shady locations, also forest edges, in bushes or on trees at up to 1-2 m height [Rogner]. Description: head moderately large, longer than broad; snout short, as long as or a little shorter than the diameter of the orbit; canthus rostralis angular; nostril nearer the tip of the snout than the orbit; eye large; tympanum large, vertically oval. Upper head-scales small, smooth or feebly keeled ; occipital scarcely enlarged; supraocular scales either all very minute or with three or four longitudinal rows of larger ones; ten or eleven upper and as many lower labials. Gular scales small, granular, enlarged and keeled on the sides near the jaws, and in front of the gular fold. Nape and back with a series of oval keeled scales, forming a more or less marked denticulation. Dorsal scales very small, granular, smooth, smallest on the sides; ventral scales rather large, squarish, strongly keeled. Limbs long, covered with imbricate keeled scales; digits long and slender; tibia longer than the head; the adpressed hind limb reaches beyond the tip of the snout. Tail: round or very feebly compressed, about twice as long as head and body, covered with keeled scales which are largest inferiorly. Coloration: very variable. Females brown, with symmetrical darker, light-edged markings consisting generally of a series of rhombs or alternating triangular spots forming a zigzag band along the middle of the back; usually a dark brown band, widening gradually, from the eye to the shoulder; lower surfaces brownish-white, with scattered brown dots. Males sometimes brown with angular blackish markings, but more usually uniform purplish brown, with the head bluish. [SOURCE: Boulenger]

E. erythroceneus

E. iheringii

Ihering's Fat-Headed Anole

SE Brazil (Rio Grande do Sul)

TL approx 29 cm (m), 29.5 cm (f), SVL approx 9 cm (m), 9.5 cm (f)

Description: distinguished from E. catenatus in the following points: nostril nearly equally distant from the orbit and the tip of the snout. The scales on the vertebral region relatively larger, subrhomboidal, flat, distinctly keeled. Limbs shorter ; tibia shorter than the head; the adpressed hind limb reaches the anterior border of the orbit in the male, the angle of the mouth in the female. Coloration: purplish-brown above, the male uniform, the female with an alternating series of black spots on the vertebral region, and on each side from nape to base of tail, a broad yellow band ; lower surfaces brownish or purplish.

E. leechii

Leech's Fat-Headed Anole

N & W Brazil

Description: In habit very similar to Enyalius catenatus, but the digits strongly keeled and pectinate inferiorly and distinctly denticulated laterally. Nostril below the canthus rostralis, much nearer the end of the snout than the orbit. Upper head-scales small, equal, strongly keeled; occipital a little enlarged; a few longitudinal rows of strongly keeled supraoculars, smaller than the scales on the vertex, surrounded by smaller granular ones; 12-13 upper and 11 lower labials. Gular scales small, granular, obtusely keeled. Dorso-nuchal crest quite indistinct (anomalous ?). Dorsal scales small, granular, keeled, laterals smaller still, obtusely keeled; ventrals much larger, squarish subrhomboidal, very strongly keeled. Limbs long, covered with equal strongly keeled scales, the hind side of the thighs finely granulate; the adpressed hind limb reaches beyond the end of the snout; the length of the tibia equals the distance between the end of the snout and the gular fold. Tail: scarcely compressed, not crested, covered with subequal keeled scales, which are largest inferiorly; its length about once and two thirds that of head and body. Coloration: chestnut-brown above; a black line from the eye to the fore limb, passing on the lower border of the tympanum; a short yellowish streak on each side of the nape; a triangular yellowish spot, pointing towards its fellow, above each shoulder; limbs with rather indistinct darker and lighter cross bands; lower surfaces brownish; an oblique arrow-headed dark-brown marking on each side of the throat; tail with a series of large, elliptical, longitudinal, blackish spots above and inferiorly, some confluent and forming rings.
