| Distribution | SE Mexico (C Guerrero, caross the Isthmus of Tehuantepec, Chiapas, Oaxaca) Type locality: Western Mexico |
| Reproduction | oviparous |
| Types | Holotype: unlocated (not found at MNHN, fide I. Ineich, pers. comm., March 2019). |
| Diagnosis | Diagnosis: Rostral slightly elongated and projecting toward the back; 9 supralabials, 3 supralabials in contact with the eye, the fourth, fifth and sixth; generally 12 infralabials, sometimes 11 or 13; single preocular; single loreal; prenasal separated from the second supralabial; a second pair of chinshields larger than the first one in contact with each other or separated by a row of scales; 194–206 ventrals; 128–141 subcaudals; tail is 29 to 34% of total length; 14–15 + 3 maxillary teeth. Color pattern consists of a pale vertebral line extending from the parietal region, and is three rows wide on the first third of the body and one row wide on the rest of the body, flanked by a pair of dark dorsolateral lines two to four scales wide, interrupted at the neck without touching the head; two dark lateral lines, sometimes slightly interrupted in the neck region or continuing toward the sides of the head, passing by the eyes to the nasal scales. Differs from the other species in the genus by having more maxillary teeth (14–15 + 3); a single preocular scale; tail length 29 to 34% of total length; 4 longitudinal lines along the body, dorsolaterals interrupted on the neck region; 194 to 206 ventral scales (HERNÁNDEZ-JIMÉNEZ et al. 2021). |
| Comment | Distribution: endemic to Mexico, reports from Guatemala appear to be erroneous. See map in HERNÁNDEZ-JIMÉNEZ et al. 2021: Fig. 3. |
| Etymology | The species name comes from the Latin ‘lemniscatus’, which means ‘adorned with bands’, doubtless in reference to the stripes along its body. |
