|Higher Taxa||Gymnophthalmidae (Cercosaurinae, Bachiinae), Sauria, Gymnophthalmoidea, Squamata (lizards)|
|Synonym||Bachia psamophila RODRIGUES, PAVAN & CURCIO 2007|
|Distribution||C Brazil (Tocantins)|
Type locality: ‘‘Tombador de areia’’ (10°02’S, 48°23’W), mu-
nicipality of Porto Nacional, state of Tocantins, Brazil.
|Types||Holotype: MZUSP 95080, an adult male, collected by D. Pavan on 13 December|
2002. The specimen was not labeled in field.
|Diagnosis||Diagnosis. A species of the bresslaui group having lanceolate dorsal and lateral body scales, quadrangular and juxtaposed smooth ventrals, tail scales lanceolate, imbricate, keeled, 2-2 femoral pores and 1-1 preanal pores in the male (absent in the female), interparietal, supraoculars, and superciliaries present, 45–49 dorsals, 35–39 ventrals, and 35–38 scales around mid-body. Snout highly prominent and wedge-shaped, distinctively projecting over lower jaw. Four clawed short toes in the hind limb; forelimb ending by one apical scale. Six supralabials; sixth the largest and the highest, contacting parietal. Fifth supralabial separated from parietal by an enlarged postocular. Two enlarged temporal scales. Two supraoculars; second small, restricted to the lateral face of head, allowing extensive contact between parietal and first supraocular. Width of first supraocular less than one-third of the anterior margin of frontal. Bachia psamophila can be immediately distinguished from B. panoplia and B. pyburni by the absence of prefrontals, present and in contact at midline in both latter species. In B. scolecoides, prefrontals are also present but widely separated and reduced in size. Like in B. psamophila prefrontals are also absent in B. bresslaui and B. cacerensis. The fifth supralabial of B. psamophila is separated from parietal by an elongate and enlarged postocular, almost as large as the fifth supralabial; the sixth supralabial is the largest and highest and contacts the parietal. In B. bresslaui, B. scolecoides, B. panoplia, and B. pyburni, there is no contact between supralabials and parietal, and in only one of the three known specimens of B. cacerensis there is slight contact between parietal and sixth supralabial. Bachia psamophila also differs from B. cacerensis by having one distinctive unclawed apical scale in the forelimb (four in B. cacerensis) and four clawed toes in the hind limb (only one in B. cacerensis).|
|Comment||Abundance: only known from its original description (Meiri et al. 2017).|
|Etymology||Etymology.—The specific name derives from the Greek ‘‘psamos’’ (sand) and is a reference to the sandy habitat preferences of this species.|
