DistributionColombia (Quindío, Caldas, Risaralda, Valle del Cauca, Cordilleras Central and Occidental)

Type locality: apparently in error, see comment  
Reproductionoviparous 
TypesLectotype: SMF 19355, paralectotypes: MCZ; other specimens: MHN-UCa, MLS, MHNUC-HE, ICN, UV-C, UF, MHUA (fide Himes et al. 2022). 
DiagnosisDIAGNOSIS: A distinct member of the trilineatus Group most obviously allied to A. resplendens and A. dunni, but differing from them in scutellation, dentition, and coloration. Distinct from other Ecuadorian Atractus in: (1) 17 scale rows; (2) long loreal; (3) maxillary teeth eight; (4) ventrals in males, 141-144 (143), in females, 148-153 (150); and (5) uniform dark brown dorsally [from SAVAGE 1960].

CommentDistribution: Reports of A. lehmanni from Ecuador (Boettger 1898, Savage 1960) are likely misidentifications since A. lehmanni has not been registered in Ecuador outside the type locality. In fact, all specimens from Ecuador that Arteaga et al. (2017) initially identified as A. lehmanni and that Torres- Carvajal et al. (2019) subsequently examined are apparently misidentified, hence the species does not even occur in Ecuador.

Type locality: Hoya de Cuenca, Prov. Azuay, Ecuador (in error, according to Himes et al. 2022).

Similar species: A. roulei (for examples of misidentifications see Passos et al. 2022).
