|Distribution||Colombia, Venezuela, NW Brazil|
Type locality: Venezuela: Apuré, 6 km W San Fernando de Apuré, at Hato la Guanota.
|Types||Holotype: TCWC 46203|
|Diagnosis||Diagnosis. Cnemidophorus gramivagus is distinguished from all other species of Cnemidophorus by the following combination of characters: nostril in the suture between nasal plates; frontoparietals usually 2 (90%); supraoculars usually 4 (82%); parietals usually 5 (98%);longitudinal rows of ventrals 8; little to no spotting on the limbs; adults usually with only two longitudinal white, yellow or yellowish-green dorsolateral stripes, which may fade posteriorly or be totally absent; juveniles with two bold white or yellowish dorsolateral stripes separated from two faint white or yellowish dorsal stripes by longitudinal band of dark ground color, sometimes with faint lateral stripes; enlarged anal spurs in males (McCrystal & Dixon 1987).|
Comparisons: Similar to C. lemniscatus, but differs in color and pattern in all age classes of both sexes, and attains a much larger size. The current working hypothesis is that ‘‘C.’’ gramivagus and ‘‘C.’’ lemniscatus are the two ancestral species of C. cryptus (Cole and Dessauer, 1993; Reeder et al. 2002).
Distribution: Probably also in Bolivia (fide LANGSTROTH 2005).
|Etymology||he adjectival name gramivagus comes from the Latin noun gramen, meaning "grass," and the Latin adjective vagus, meaning "wandering." The name means "grass wandering" and refers to the Llanos grasslands from where the type specimens were collected.|
