Cnemidophorus pseudolemniscatus — HARVEY et al. 2012 
DistributionSuriname, French Guiana

Type locality: Surinam: Marowijne: Albina, on the Marowijne River  
ReproductionParthenogenetic species. See also C. lemniscatus. ‘‘Cnemidophorus’’ pseudolemniscatus is a triploid clonal parthenogen of hybrid origin, which is hypothesized to have been ‘‘C.’’ cryptus x ‘‘C.’’ lemniscatus (Dessauer and Cole, 1989; Cole and Dessauer, 1993). 
TypesHolotype: AMNH 133304, female 
DiagnosisDIAGNOSIS: A cryptic species of the Cnemidophorus lemniscatus complex distinguished from all others in the genus by the following combination of characters: abruptly enlarged mesoptychials; granular postantebrachials; usually 2 frontoparietals; 5-7 parietals (usually depending on endmost being divided or not into anterior and posterior portions); usually 4 supraoculars each side; nostril centered (anterior to posterior) within suture between nasal plates; unisexual (only females exist); adults usually with 5-7 longitudinal light stripes (9 in juveniles), 4 particularly dark stripes (6 in juveniles), numerous conspicuous light spots on legs (same in juveniles), faint light spots if any on arms (conspicuous in juveniles), conspicuous small light spots laterally on body (inconspicuous or absent in juveniles); maximum snout-vent length about 70 mm; triploid number of 75 chromosomes, largest three being heteromorphic with two submetacentric to subtelocentric chromosomes and one subtelocentric to telocentric chromosome. (Cole & Dessauer 1993)

EtymologyNamed after Greek pseudo (ψευδο), false, untrue, mistaken + Latin lemniscatus, species of Cnemidophorus due to Linnaeus, 1758 (see). [“...The name is in reference to the morphological similarity to C. lemniscatus, under which name these lizards have been masquerading until now...”]. (from Esteban Lavilla, pers. comm., May 2024)
