| Distribution | Argentina (Formosa, Corrientes), Brazil
Type locality: Laguna Brava (27° 30’ S, 58° 43’ W), Capital Department, Corrientes Province, Argentina.

| Diagnosis | Diagnosis: A small form of Amphisbaena without major fusion of head shields; with one pair of large parietals and enlarged occipitals; a blunt-tipped cylindrical tail with a faint autotomy annulus at the eighth caudal annulus; two cicatricial precloacal pores separated by a pair of nonpored medial scales (hiatus), or without pores. Specimens have 202 to 213 body annuli; 18 to 19 caudal annuli; 16 to 17 dorsal and 18 to 22 ventral segments to the midbody annulus; one or two rows of postgenials and a postmalar row. The color of preserved specimens is light brown with the ventral region cre`me white, similar to that of live specimens (following Gans and Alexander, 1962). |
| Comment | Has been confused previously with A. dubia by Yanosky et al. 1993, Montero 1994, and others.
Morphology: This species is one of ~20 species of Amphisbaena with two precloacal pores (Ribeiro et al. 2019). |
| Etymology | Named after the Latin word hiatus, meaning gap, in reference to the gap between the precloacal pores, which is a distinctive characteristic of this species. |
