|Higher Taxa||Amphisbaenidae, Amphisbaenia, Lacertoidea, Squamata|
|Synonym||Anops acrobeles RIBEIRO, CASTRO-MELLO & NOGUEIRA 2009|
Amphisbaena acrobeles (by implication fide MOTT & VIEITES 2009)
Amphisbaena acrobelis — PEREZ et al. 2012
|Distribution||Brazil (Tocantins: Jalapão Region in the Cerrado)|
Type locality: close to the northern limits of Serra Geral do Tocantins Ecological Station, Tocantins, Brazil.
|Types||Holotype: MZUSP 96337 (field number CN 1034), specimen (sex undetermined, specimen with posteriormost section of body mutilated) from a pit-fall trapping site covered with typical Cerrado savannas, close to the northern limits of Serra Geral do Tocantins Ecological Station.|
|Diagnosis||Diagnosis: This new species of Anops may be distinguished from A. bilabialatus and A. kingii by showing an extremely narrow head (37.2% head length vs. 62.5–77.6% head length; Fig. 4); a row of eight occipitals anterior to the first body annulus (Fig. 3A; vs. scutes absent); temporal present (Fig. 3B; vs. absent); mental and postmental fused (vs. distinct); four rows of postgenials located between malars (Fig. 3C; vs. one); two malars posterior to the second infralabial (Fig. 3C; vs. one). Additionally, A. acrobeles differs from A. bilabialatus by showing an elongate rostral in contact with the frontals (vs. rostral relatively short and separated from the frontals); frontal longer than wide (vs. frontal wider than long); ocular relatively elongate, representing 27.7% of head length (vs. short ocular, 12.5–14.7% of head length); three supralabials (vs. two); postsupralabial absent (vs. present); three infralabials (vs. two). It further differs from A. kingii by not showing a preocular and a postsupralabial (vs. present). Moreover, second supralabial in the new species is ca. two times longer than the other supralabials (vs. supralabials with similar proportions); second supralabial longer than high (vs. second supralabial higher than long); 296 + n (specimen mutilated, missing posterior third of body) body annuli (vs. 214– 244 body annuli).|
|Comment||Abundance: only known from the type specimen (Meiri et al. 2017).|
|Etymology||The name ‘‘acrobeles,’’ from the Greek ákros = distal portion, and, beles = pointed. The specific epithet is a reference to the extremely acute rostral of the new species, much more pronounced than in the other two species of the genus [according to RIBEIRO et al. 2009 there are 3 species in Anops: acrobeles, bilabialatus, and kingii].|
