DiagnosisDescription (genus): The genus Laemanctus consists of medium-large iguanid lizards (snout-vent length to 150 mm) with laterally-compressed body, extremely long tail, legs, and toes, and a unique flat-topped cephalic casque. The dorsal and ventral body scales are large, keeled, and imbricate, and the middorsal row is usually enlarged. The gular fold may be present or absent. The subdigital lamellae are keeled, but not flanged or fringed. Laemanctus is probably most closely related to the genera Basiliscus Laurenti and Corytophanes Boie, and the three genera have been loosely grouped as the "basiliscine" iguanids (Cope, 1900; Etheridge, 1964). The geographic range of the genus Laemanctus extends throughout Atlantic drainage lowlands between sea level and 650 m elevation (Gadow, 1910), from central Tamaulipas, Mexico, to the Rio Ulua drainage of northwestern Honduras. The map presented by Savage (1966:fig. 22, p. 754) is a good approximation of all but the northern-most part of the range of Laemanctus. Laemanctus is an autochthonous Mesoamerican genus, which has not expanded its range beyond the humid lowlands of eastern Central America (Stuart, 1957; Savage, 1966, McCoy 1968).

Diagnosis: Anterior dorsal head scales small and irregular; posterior edge of head lacking a fringe of enlarged conical scales (Fig. 2); middorsal scales not enlarged, no free serrate dorsal crest (McCoy 1968).

Diagnosis (longipes): A subspecies of L. longipes characterized by large size; small body scales (average 55 around midbody); gular fold well developed and continuous, with 3-5 rows of granules; anterior dorsal head scales larger than posterior dorsal head scales (McCoy 1968).

Definition (deborrei): A subspecies of L. longipes characterized by moderate size; medium-sized body scales (average 43 around mid-body); gular fold well developed and continuous, with two or three rows of granules; dorsal head scales subequal in size (McCoy 1968). 
CommentType species: Laemanctus longipes WIEGMANN 1834: 46 is the type species of the genus Laemanctus WIEGMANN 1834.

Synonymy: Laemanctus longipes waltersi SCHMIDT 1933 is now considered as a valid species.

Distribution: not in Yucatan state (Mexico) according to GONZÁLEZ-SÁNCHEZ et al. 2017. 
EtymologyThe generic name apparently is derived from the Greek words laminos, meaning "throat" and anctus, meaning "press together," presumably in reference to the tapered crowns of the marginal teeth (Lemos-Espinal & Dixon 2013).

The patronym waltersi honors Leon L. Walters, the taxidermist at the FMNH, who accompanied Schmidt when the holotype was collected.
