TypesHolotype: TCWC (Texas Cooperative Wildlife Collection) 
DiagnosisDIAGNOSIS. Coleonyx reticulatus is a large gecko (snout-vent length 84 mm, tail 58 mm regenerated) with 13 irregular longitudinal rows of dorsal tubercles. There are 24 lamellae beneath the fourth finger and 31 beneath the fourth toe, and only the tips of the claws extend beyond the sheath scales. The dorsum has a profusion of small dark spots and reticulations on a light tan ground color.
These characters, except for the color, distinguish C. reticulatus from all other species of Coleonyx. Coleonyx elegans and C. mitratus have 19 to 23 longitudinal rows of dorsal tubercles, 18 to 20 fourth toe lamellae, and 14 to 17 fourth finger lamellae. Enlarged dorsal tubercles are absent in the much smaller species C. brevis and C. variegatus [Dixon 1970].
EtymologyFrom the Latin reticulatus, made like a net. In reference to the net-like dorsal pattern.
