| Diagnosis | Diagnosis: Within the Liolaemus darwinii complex, adult males of Liolaemus abaucan may be distinguished from L. darwinii, L. olongasta and L. laurenti in lacking intensely dark pigment within the antehumeral fold, from L. quilmes, L. ornatus, L. irregularis and L. uspallatensis in having the postscapular spots enlarged; and, from L. ornatus and L. irregularis in having precloacal pores in 10 per cent or fewer of the females rather than more than 95 per cent, and a very different dorsal pattern (Etheridge 1993: 165). Variation. Maximum size, and variation in tail/total length, scale counts, and prec10acal pores are provided in Tables 1-4. No neonatal individuals available; smallest male 47 mm snout-vent length, smallest female 41 mm, both with fully adult pattern (Etheridge 1993: 166). Coloration: Ground color usually grey or bluish-grey, sometimes a light brick-red. Males usually without stripes, but middorsal and dorsolateral stripes sometimes indistictly indicated on neck and anterior body. Prescapular and postscapular spots always large and distinct, usually followed by one or more enlarged lateral spots. Paravertebral spots highly variable, sometimes distinct but more often modified by a change in shape, fragmentation or loss; anterior paravertebral spots frequently transversely enlarged to form, with adjacent lateral spots, indistinct cross bands on neck and anterior body. Throat immaculate, or more often with diffuse, greyish pigment or an indistict reticulum or spots. Female dorsal pattern with moderately distinct stripes and spots of standard pattern, or stripes and spots variously fragmented, reduced or absent; some females nearly solid grey above, with only ventrolateral light stripes indicated as a series ofsmall, light spots. All with dorsal surface ofdigits white or pinkish; dorsal surface of tail sometimes pinkish, most noticeable in the smallest female examined. Ventral surfaces as in males, but with throat pigmentation less developed. Gravid females with orange or reddish-orange pigment on the sides of the head and neck (PI. 2.2, Etheridge 1993: 166). |
