Liolaemus isabelae belongs to the "chilean" group and is closer to the "nigroviridis" complex. Liolaemus isabelae differs from all other species of Liolaemus by the unique features of a jet-black color with small yellowish spots on the head, hind-legs and tail. In contrast with other jet-black species, L. isabelae is slender than L. curis, and the dorsal scales of L. curis are sharpened, whereas L. isabelae has round dorsal scales. L. zapallarensis ater is glossy on both back and ventral surfaces whereas L. isabelae is glossy just on the ventral surface. Likewise they differ in chromosome number. Females of L. isabelae resemble those of L. nigroviridis.
Although Ortiz (1994) failed to provide a formal diagnosis for L. nigroventrolateralis, he did indicate, in the abstract, that it has a "dorsal color pattern with a mid dorsal yellow band spotted with black dots, and a strong melanism running from the axilla to the groin, gut area, -eular region, ventral surface of forelegs, hind legs and tail, lorv number of precloacal pores (2) and a moderate number of midbody scales", the same diagnostic traits previously described for L. isabelae by Navarro & Nuñez ( 1993).
