Type locality: Colônia Nova, Rio Gurupi, Pará, Rodovia Br-316, 10 Km antes do Gurupi, 01°26’ S, 47°32’ W.  
TypesHolotype: MPEG 10.131, adult male 
DiagnosisDiagnosis. A species of Atractus with 17 dorsal scales rows, differing from all congeners by the following combination of characters: (1) large size, adults reaching about 700 mm in TL; (2) loreal long (about three times longer than high); (3) generally seven (rarely eight) supralabials with third and fourth (fourth and fifth whenever eight supralabials are present) in contact with eye; (4) generally eight (rarely seven) infralabials with first four in contact with chinshields; (5) six to seven maxillary teeth; (6) 151–180 ventral scales in females and 137–165 in males; (7) 19–28 subcaudal scales in females and 27–45 in females; (8) tail of moderate length: Tail/TL 6.9– 17.6%; (9) dorsal color pattern of dark gray/brown ground coloration with pale crossbands or blotches usually edged in black, or dorsal ground color pale brown with dark brown or black blotches [SCHARGEL et al. 2013]

Revised diagnosis in Melo-Sampaio et al. 2021: 723.

Comparisons: in Melo-Sampaio et al. 2021: 723.

Color in life: The extreme dark morph is represented by MZUSP 21474, with sepia dorsum of head covering frontal and postoculars, and a pale buff [color 1] band covering temporals, parietals, one row of occipitals, and two last supralabials; sepia body dorsum with buff transverse bands one-half to one scale long interrupted or not on the vertebral axis; venter light buff with Burnt umber spots forming midventral line; venter of specimen UFRO-H 2549 immaculate chamois [color 83] on the first quarter, with tiny sepia dots increasing in number posterior to midbody, forming a diffuse midventral line at the level of six scales before cloaca (Figure 3, Melo-Sampaio et al. 2021). 
CommentSimilar species: A. major (in Ecuador); A. badius (in Argentina, Bolivia, Brazil, Ecuador and Peru). Note that A. snethlageae is quite variable. A. schach (for examples of misidentifications see Passos et al. 2022).

Synonymy: after Melo-Sampaio et al. 2021 (see refs. there) 
EtymologyNamed after Dr. Maria Elizabeth Emilia Snethlage (1868-1929), a German ornithologist and former assistant in zoology at Museum für Naturkunde Berlin.
