|Higher Taxa||Teiidae, Teiinae, Gymnophthalmoidea, Sauria, Squamata (lizards)|
|Synonym||Ameiva aggerecusans KOCH, VENEGAS, RÖDDER, FLECKS & BÖHME 2013|
Type locality: Balsas, Province of Chachapoyas, Region of Amazonas, Peru, 06°49’11.6’’S, 78°00’12.2’’W, 1000 m elevation.
|Types||Holotype: ZFMK 85024, adult male, Figs. 5, 6A, collected on 08 July 2005 by P. Venegas and C. Koch.|
|Diagnosis||Diagnosis and comparison. This comparatively small Ameiva is diagnosed by the following combination of characters: (1) maximum known SVL of 99.3 mm; (2) lacking longitudinal ridge on frontal scale; (3) frontal plate divided in two subequal scales; (4) postnasals separated from prefrontals by frontonasals; (5) parietal scales 5–7; (6) median gular scales not enlarged; (7) enlarged median mesoptychial scales slightly larger than largest gulars; (8) gulars posterior to the interauricular crease smaller than anterior gulars; (9) nasal suture passes through the superior half or centrally through nostril; (10) rostral not contacting or in short contact with postnasal; (11) supranasals not contacting or in short contact with supralabials; (12) scales of circumorbital semicircle not extending to anterior margin of third supraocular; (13) 30–33 enlarged ventral scales between gular and vent; (14) 10–12 longitudinal rows of ventral plates, outermost often distinctly smaller; (15) 73–92 DOM; (16) 144–198 DL; (17) postbrachials not or hardly dilated; (18) 31–39 LFT; (19) 26–32 SCF; (20) 12–22 FP; (21) cream-colored vertebral stripe present in most females and juvenile specimens.|
Ameiva aggerecusans sp. nov. can be differentiated from all other mainland congeners except for A. bifrontata, A. concolor and A. nodam sp. nov. by having a transversely divided frontal plate. From A. bifrontata and A. nodam sp. nov. this species can be distinguished by lacking distinctly dilated postbrachials. It resembles A. concolor but has a lower maximum SVL and a distinctly more defined cream-colored vertebral stripe on the dorsum.
|Comment||Ameiva aggerecusans sp. nov. has not or only hardly dilated postbrachials, a maximum known snout-vent length of 99.3 mm, 10–12 longitudinal rows of ventral plates, 73–92 midbody granules, 31–39 lamellae under the fourth toe, and the females and juveniles of the species normally exhibit a cream-colored vertebral stripe on a dark dorsum ground color.|
|Etymology||“The specific epithet is an agglutination of the Latin nomen “agger” which means dam and the verb “recusare” which means reject. As in Ameiva nodam sp. nov. this name was chosen to further emphasize our protest against the possible dam constructions along the Marañón river.” (KOCH et al. 2013)|
