TYPE LOCALITY (BY NEOTYPE DESIGNATION). — Parque das Dunas, 12°55’3”S, 38°19’12”W, 20 m a.s.l., municipality of Salvador, state of Bahia, Brazil ( Fig. 3 View FIG ).
ETYMOLOGY. — The specific name ocellifera (masculine ocellifer ) means “bearing little eyes”. It derives from the Latin ocellus (diminutive of oculus, i.e., “small eye”) and fero (“to carry”, “to bear”), in reference to the series of small bluish ocelli between the fore and hindlimbs.

COMPARISON WITH OTHER AMEIVULA SPECIES
The following characters (see Table 2 View TABLE and Table 3 View TABLE ) distinguish A. ocellifera from its congeners (data in parentheses). Ameivula ocellifera differs from A. abalosi in having 82-141 scales around midbody (75-98), 26-38 subdigital lamellae under fourth toe (24-31), and whitish blue ocelli (light-blue or whitish green ocelli). Ameivula ocellifera differs from A. apipensis in having 14-28 femoral pores (12-17), 26-38 subdigital lamellae under fourth toe (24-27), vertebral stripes absent (present), whitish-blue ocelli (no ocelli), and immaculate throat (yellow). Although the description of A. apipensis indicates an intertympanic sulcus (absent in A. ocellifera ), the figures available indicate the contrary, i.e., the absence of such structure in A. apipensis . Ameivula ocellifera differs from A. cipoensis in having 13-20 subdigital lamellae under fourth finger (12-14), 26-38 subdigital lamellae under fourth toe (21-24), lower lateral stripes broken (absent), whitish-blue ocelli (yellow-greenish ocelli), and hindlimb spots present (absent). Ameivula ocellifera differs from A. confusioniba in having paravertebral and dorsolateral fields present (absent), paravertebral and lower lateral stripes present (absent), whitish-blue ocelli (bright yellow ocelli), and hindlimb spots present (absent). Ameivula ocellifera differs from A. jalapensis in having eight longitudinal rows of ventral scales (6-8), 14-28 femoral pores (10-16), 172- 248 dorsal scales (200-250), 35 gular scales (41-64), larger body size (maximum SVL, 56 mm), vertebral stripe absent (broken), upper and lower lateral fields spotted (uniform), whitish-blue ocelli (no ocelli), hindlimb spots present (absent), and immaculate throat (lime-green). Ameivula ocellifera differs from A. mumbuca in having eight longitudinal rows of ventral scales (6-8), 172-248 dorsal scales (194-271), 26-38 subdigital lamellae under fourth toe (24-32), 35 gular scales (38-49), larger body size (maximum SVL, 59 mm in males), lower lateral fields spotted (uniform), and whitish-blue ocelli (whitish-blue spots only in males). Ameivula ocellifera differs from A. nativo in having 25-31 transverse rows of ventral scales (29-32), vertebral stripe absent (present), paravertebral fields present (absent), paravertebral and lower lateral stripes present (absent), upper and lower lateral fields spotted (uniform), whitish-blue ocelli (no ocelli), hindlimb spots present (absent), immaculate throat (light blue), and bisexual (only females). Ameivula ocellifera differs from A. nigrigula in having 21-30 scales around tail (27-32), whitish-blue ocelli (bright turquoise ocelli), hindlimb spots present (absent), and throat region immaculate (black). Ameivula ocellifera differs from A. pyrrhogularis in having 172-248 dorsal scales (192- 255), 21-30 scales around tail (23-33), vertebral stripe absent (present in juveniles and females), whitish-blue ocelli (light blue or greenish-blue ocelli), and immaculate throat (orange in adult males). Ameivula ocellifera differs from A. xacriaba in having 26-38 subdigital lamellae under fourth toe (23-28), 35 gular scales (41-52), paravertebral stripes present (absent), whitish-blue ocelli (bright green ocelli), and hindlimb spots present (absent). Although the description of A. xacriaba indicates an intertympanic sulcus (absent in A. ocellifera ), the figures available reveal the contrary, i.e., the lack of such structure, but with an interauricular crease in A. xacriaba . Less marked differences between species can be found in Table 2 View TABLE and Table 3. View TABLE

DISTRIBUTION
The current known geographic range of Ameivula ocellifera is in the southeastern portion of the Caatinga (states of Pernambuco, Alagoas, Sergipe, and Bahia) and part of the Atlantic Forest of eastern Bahia (including Salvador, its type locality), Sergipe, and Alagoas ( Arias et al. 2018). The identity of populations from central and north Caatinga (Paraíba, Rio Grande do Norte, Ceará, and Piauí) is under revaluation, and may reveal a distinct taxon in the near future. Records attributed to A. ocellifera in northern Brazil (Rondônia, Pará, and Tocantins), midwestern Brazil (Mato Grosso, Mato Grosso do Sul, Goiás, Distrito Federal, Minas Gerais, and São Paulo), and northeastern Brazil (Maranhão) ( Costa et al. 2022) represent candidate species close to A. ocellifera (e.g. “W-Ce clade” in Arias et al. 2018) or probably misidentifications.
