DistributionMexico (Pacific versant of the Sierra Madre Occidental in Mixed Boreal-Tropical habitat near the Durango/Sinaloa state border)

Type locality: 4.0 km west of El Palmito on Hwy. 40, Municipio Concordia, Sinaloa, México (23° 33’ 14.2’’ N, 105° 50’ 47.2’’ W), 2000 m elevation.  
TypesHolotype: UANL 5684 
DiagnosisDiagnosis.-A species of tricolored kingsnake most closely resembling Lampropeltis pyromelana and Lampropeltis mexicana but differing from those species in a number of characters. Lampropeltis webbi can be distinguished from L. pyromelana based on a primarily black snout, the smaller number of white annuli, and a different head pattern. It differs from L. mexicana in having a higher number of ventral and subcaudal scales and in having a different body pattern. In addition, L. webbi is distinguished from L. pyromelana and L. mexicana and all other members of this genus, by mitochondrial DNA markers. The following combination of nucleotide states within the ND4-Leu gene region is diagnostic for L. webbi in our analysis. The numbers refer to the positions within the aligned sequences referenced in Appendix 1; position 1 corresponds to position 11703 of the complete Dinodon semicarinatus mitochondrial genome (GenBank accession number NC 001945). [from BRYSON et al. 2005]

Diagnosis: Modified from Bryson et al. (2005) to include data on new specimens. A small species of kingsnake (TL: at least 756 mm) with a tricolor pattern most similar to taxa in the mexicana complex (Fig. 30). It differs from the geographically closest members of the mexicana complex, L. greeri and L. ruthveni, by the presence of a higher number of ventral scales (216–221 vs. 197–204 in L. greeri, and 182–196 in L. ruthveni), and by a different body and head pattern (Fig. 18). [ HANSEN & SALMON 2017: 741]
CommentNote that the diagnosis of this species is fairly vague.

Distribution: see map in  HANSEN & SALMON 2017: 722 (Fig. 17).
