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 and Table 3) 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 and Table 3.

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., Published as part of Oliveira, Eliana F., Costa, Henrique C., São-Pedro, Vinícius A., Marques, Ricardo, Santana, Diego J., Colli, Guarino R., Mesquita, Daniel O. & Costa, Gabriel C., 2022, On the type locality of Ameivula ocellifera (Spix, 1825) (Squamata, Teiidae), with a neotype designation, pp. 475-491 in Zoosystema 44 (19) on pages 482-487, DOI: 10.5252/zoosystema2022v44a19, http://zenodo.org/record/7245521, {"references":["SPIX J.

Animal colouration plays a key role in inter and intraspecific interactions, pre-eminently in mate signalling. When multiple types of colouration occur within sexes it is possible that they show alternative reproductive strategies. In lizards, most colouration studies do not incorporate how colour is perceived by conspecifics. Here, we used unbiased colour analysis methods (spectrophotometry and visual modelling) to test for sexual dimorphism and within male dichromatism in the Striped Lava Lizard. We found that males express two distinct colourations that are different from females in several dorsal and ventral body regions. Our results showed UV reflection at the throat, an important body region for signalling. Ventral patches, the coloured badge seen in adult males of Tropidurus spp, have two distinct colour classes within males (Y and B males). Morphs are best discriminated by blue and yellow chroma, and brightness. Body size had little influence on colouration, suggesting that colour may be linked to inheritance rather than growth. Our study clearly shows sexual dichromatism and the existence of colour morphs in this species. Moreover, morph differences in colouration are perceptible by conspecifics. These differences are not only between ventral patches, but also in other body parts such as the dorsum, previously considered as cryptic by human observers. We suggest that colouration at the ventral patches and throat might play a role in intraspecific interactions. Patches increase colour intensity during breeding season and are likely to be costly by pigment-based expression, whereas throat’s UV reflection might have a cost infringed by conspicuousness.
