|Distribution||Mexico (Coahuila, Nuevo León, Tamaulipas)|
Type locality: ““Mexico, Nuevo Leon”
thayeri: Mexico (Tamaulipas, Nuevo León); Type locality: Miquihuana, Tamaulipas.
|Types||Holotype: BMNH 220.127.116.11 (re-registered as 1918.104.22.168)|
Holotype: MCZ 19551 [thayeri]
|Diagnosis||Diagnosis: A moderate-sized (maximum TL = 1,219 mm) species of kingsnake characterized by extensive intra- populational and geographic pattern variation, including a coralsnake mimic pattern and a melanistic phenotype. This species is most similar to some populations of L. alterna and L. greeri, but differs from L. alterna by the presence of a golden-brown iris (vs. silver-gray in L. alterna), the head is only slightly distinct from the neck (vs. noticeably distinct in L. alterna), the eyes protrude only slightly from the outline of the head (vs. prominently so in L. alterna), and lower ventral scale counts (194–212 in L. leonis vs. 211–230 in L. alterna) (Fig. 18).|
Compared to L. greeri, L. leonis exhibits high levels of pattern polymorphism as well as melanism. The snout and head color matches the body ground color only in some individuals of L. leonis, compared to matching in all specimens of L. greeri examined. Most individuals of L. leonis lack black post-ocular markings, which are present in L. greeri. Ontogenetic color pattern change is common in captive-bred L. leonis and absent in L. greeri (Figs. 25, 26). [HANSEN & SALMON 2017: 736]
|Comment||Synonymy: mostly after HANSEN & SALMON 2017. Other authors still consider leonis as a synonym of L. mexicana (e.g. Nevárez-de los Reyes et al. 2016).|
Distribution: see map in HANSEN & SALMON 2017: 722 (Fig. 17). Not listed for Nuevo León by Nevárez-de los Reyes et al. 2016.
