DistributionBrazil (Rondônia)

Type locality: Fazenda Cachoeira (12° 32’ 07” S, 60° 25’ 36” W), 50 km NW of Vilhena, Rondônia, Brazil, elevation 612 m.  
Reproductionoviparous 
TypesHolotype: UNB 09811, adult male (also as CHUNB for the Coleção Herpetológica) 
DiagnosisDiagnosis: A species distinguished from all other members of the lemniscatus group by the following combination of characters: (1) large size, maximum SVL 90 mm; (2) 34–47 scales around tail; (3) 25–33 femoral pores; (4) 190–252 dorsals; (5) dorsolateral fields absent; (6) vertebral field spotted; (7) paravertebral stripes absent (Fig. 4); and (8) preanal spurs absent. Cnemidophorus parecis differs from C. lemniscatus in having 11–14 supralabials (14–16 in C. lemniscatus), 10–15 infralabials (15–19), 25–33 femoral pores (44– 54), 34–47 scales around tail (24–30), dorsolateral fields absent (dark), vertebral field spotted (dark), paravertebral stripes absent (continuous), vertebral line absent (two continuous stripes) (Fig. 5), hindlimb spots absent (present), and ventral caudals smooth (keeled). Cnemidophorus parecis differs from C. gramivagus in having 25– 33 femoral pores (40–51 in C. gramivagus), 34–47 scales around tail (20–32), lower lateral fields light (absent), upper lateral fields light (dark), dorsolateral fields absent (dark), vertebral field spotted (dark), paravertebral stripes absent (continuous) (Fig. 5), lower lateral stripes interrupted (absent), hindlimb spots absent (present), and ventral caudals smooth (keeled). Cnemidophorus parecis differs from C. cryptus in having 11–14 supralabials (14–17 in C. cryptus), 8–10 transverse rows of ventrals (7–8), 25–33 femoral pores (38–48), 34–47 scales around tail (22–30), upper lateral fields light (dark), dorsolateral fields absent (dark), paravertebral stripes absent (continuous) (Fig. 5), and ventral caudals smooth (keeled). Cnemidophorus parecis differs from C. littoralis in having 34–47 scales around tail (25–34 in C. littoralis), upper lateral fields light (dark), paravertebral stripes absent (interrupted), vertebral line absent (interrupted) (Fig. 5), and dorsal caudals keeled (smooth). Cnemidophorus parecis differs from C. ocellifer in having 8–10 transverse rows of ventrals (5–8 in C. ocellifer), 25– 33 femoral pores (16–28), 34–47 scales around tail (21–30), and lateral spots absent (present) (Fig. 5).(Colli et al. 2003)

CommentBisexual with sexual dimorphism.

Group: this species belongs to the ocellifer group, however, this has been questioned by ARIAS et al. 2011.

Distribution: Probably also in Bolivia (fide LANGSTROTH 2005).

Diet: a large percentage of the diet of this species (10-30%) consists of ants (Lucas et al. 2023). 
EtymologyNamed after the Western Brazilian highlands, Chapada dos Parecis which is named after the Paresi indigenous people.
