DistributionGuatemala (Alta Verapaz), elevation 1000–1830 m

Type locality: Three km south of Finca Samac, Alta Verapaz, 6 km [straight line] due west of Cobán), Guatemala, 1350 m.  
Reproductionoviparous 
TypesHolotype: UMMZ 90232 
DiagnosisDIAGNOSIS. An anole very close to A. schiedii Wiegmann. It has small, keeled dorsal scutes, feebly keeled ventrals, carinate head scutes, and the males lack enlarged postanals. From schiedii it is readily distinguished by its small ventrals and its carinate, rather than rugose, head scales, and, possibly, by its keeled ventral scales. (Stuart 1942)

DESCRIPTION OF HOLOTYPE. Dorsal head scales roughly sub- equal, rugose posteriorly, carinate anteriorly. Supraorbital semicircles distinct, separated by three rows of scales medially. About a dozen enlarged, carinate scutes forming a supraorbital plate which is separated from supraciliaries and supraorbital semicircles by smaller, granular scales. Parietal no larger than surrounding scales, much smaller than the moderately large ear opening. Canthus sharp ; seven rows of loreal scales ; seven supralabials to below center of eye. Dorsal scales juxta- posed, sharply keeled, those of the middorsal region about twice the size of the granular laterals, numbering about seventy-five from the level of the axilla to the groin. Ventrals very feebly keeled, imbricate; about fifty-five between levels of axilla and groin. Tail covered with subequal, imbricate, sharply keeled scales. Tail vertically oval ; strongly compressed and slightly expanded at tip. No enlarged postanals in male. Dewlap large. (Stuart 1942)

Coloration: Dorsally, the ground color of the head and body is brown without marking except for slightly darker patches on the body. The legs are lighter brown above with no pattern. The dorsal ground color grades gradually into the brownish white of the ventrum. The chin and throat are white. The undersides of the legs are white, mottled with light brown. The dewlap is pinkish (brilliant purple in life). (Stuart 1942)

VARIATION. The paratypic series is essentially like the holo type. The majority of the specimens have the scales of the supraorbital plate in contact with the supraorbital semicircles, and frequently there are but two scales between the latter. In several females there is a narrow, distinct, dark, middorsal stripe. The females have larger ventral scutes than do the males. (Stuart 1942)
