| Diagnosis | Diagnosis: A species distinguished from other South American cis-Andean species of Ameiva by the following combination of characters: (1) 6–11 infralabials; (2) 0–2 chinshields; (3) 1–2 gular folds; (4) 3–6 parietals; (5) 31–35 transverse rows of ventrals; (6) 10–11 ventrals in transverse row; (7) 24–32 femoral pores; (8) 9–13 rows of prefemorals; (9) 2–60 precloacals; (10) 22–30 fourth toe lamellae; (11) 41–49 scales around the tail; (12) 201–284 dorsals; (13) dorsolateral stripes mostly interrupted; (14) upper lateral stripes interrupted; (15) lower lateral stripes mostly inter- rupted; (15) lateral spots absent; (16) hind limbs spotted; (17) chinshield contact greater than half of their lengths; 106mm maximum SVL. Ameiva jacuba differs from A. ameiva in having 10–11 ventrals in transverse row (12), 24–32 femoral pores (34–43), lateral spots absent (present), smaller body size, maximum SVL 106 mm (190 mm, Vitt & Colli 1994). Ameiva jacuba differs from A. parecis in having 6–11 infralabials (10–15 in A. parecis), upper lateral stripes interrupted (mostly continuous), spotted hind limbs (spots absent), mostly interrupted dorsolateral stripes (mostly continuous), larger body size, maximum SVL 106 mm (90 mm, Colli et al. 2003a,b), head brown with white spots (lime green laterally); ventral aspect of head predominantly white (yellowish), lateralmost longitudinal rows of ventrals white (vivid blue). Ameiva jacuba differs from A. bifrontata Cope 1862 in having a frontal undivided (divided transversally in the mid-region in A. bifrontata), granules between supraoculars and frontals absent (pres- ent), smaller size, maximum SVL 106 mm (101–116 mm), 6–11 infralabials (12) (Cope 1862; Boulenger 1885; Barbour & Noble 1915). Ameiva jacuba differs from A. provitaae Garcia-Pérez 1995; in having a frontal undivided (divided transversally in the mid-region in A. provitaae), smaller size, maximum SLV 106 mm (110–130 mm), 6–11 infralabials (12), 96–133 scales around mid-body (142 in A. provitaae holotype), vertebral line absent (present) (Garcia-Pérez 1995). Ameiva jacuba differs from A. vittata (Boulenger 1902) by having 96–133 scales around mid- body (74) and 24–32 femoral pores (18) (Boulenger 1902; Vance 1978). Ameiva jacuba differs from A. atrigularis (Garman 1887) by having 96–133 scales around mid-body (134–179 in A. atrigularis), 24–32 femoral pores (31–42), 22–30 fourth toe lamellae (32–41), 201–284 dorsals (263– 361) and smaller size, maximum SVL 106 mm (186 mm) (Barbour & Noble 1915). Ameiva jacuba differs from A. pantherina Ugueto & Harvey 2011 by having 96–133 scales around mid-body (137–163 in A. pantherina), 24–32 femoral pores (32–40), 22–30 fourth toe lamellae (30–37), 201–284 dorsals (291–343) and smaller size, maximum SVL 106 mm (152 mm) (Ugueto & Harvey 2011). Ameiva jacuba differs from A. praesignis (Baird & Girard, 1852) by pre- senting 96–133 scales around mid-body (111–157 in A. praesignis), 24–32 femoral pores (28–42), 22–30 fourth toe lamellae (29–40), 201–284 dorsals (237–348) and smaller size and maximum SVL 106 mm (243 mm) (Ugueto & Harvey 2011). |
| Comment | Habitat: interfluvial plateau grassland, a habitat type largely converted by agriculture outside the park limits. Diet: a large percentage of the diet of this species (10-30%) consists of ants (Lucas et al. 2023). |
| Etymology | Jacuba originates from the Tupi y-acub, which means warm water, and is also the name of a river with headwaters in Parque Nacional das Emas. In Portuguese, it further refers to a pap prepared from cassava flour, mixed with water, milk or aguardiente (‘cachaça’), and sugar, honey or raw brown sugar (‘rapadura’), which was popular among mule troopers in the eighteenth and nineteenth centuries. |
