from "the Torrejon Beds at Torrejon Arroyo," i.e., Sinclair and Granger Locality 10 or 11
from "the Torrejon Beds at Torrejon Arroyo," i.e., Sinclair and Granger Locality 10 or 11]. Its type specimen is Amer. Mus. No. 5179, a partial skeleton (lower jaw and postcrania), and it is a 3D body fossil. Its type locality is Torrejon Arroyo, which is in a Torrejonian terrestrial horizon in New Mexico. It is the type species of Listrognathosuchus.

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. C. Mook 1930 | Mandible very long in proportion to its breadth, the breadth constituting only 29 per cent. of the length, compared with 54 per cent. in L. sternbergii. Undulation of alveolar border slight. Number of teeth greater than in other species, being 28 in each ramus. Splenials just reach symphysis, which extends back to the level of the fifth teeth. |
