| Distribution | Mexico (Durango, Nayarit, eastward to Zacatecas, Aguascalientes, Jalisco, Sinaloa) Type locality: "Rancho Santa Barbara (Weicher Ranch), 29 miles west-southwest of Ciudad Durango, Durango, Mexico." |
| Reproduction | oviparous |
| Types | Holotype: MSU 190 |
| Diagnosis | Diagnosis: A moderate-sized (maximum TL = 1,156 mm) tricolored kingsnake most similar to L. alterna and some populations of L. leonis. It differs from nearest populations of L. alterna by the presence of a golden-brown to dark brown eye color (vs. silver-gray in L. alterna), black head cap markings (mostly absent in L. alterna), the head only slightly distinct from the neck (vs. prominently so in L. alterna), the eyes only slightly protruberant (vs. prominently so in L. alterna), and lower ventral scale counts (197–204 in L. greeri vs. 211–230 in L. alterna) (Fig. 18). Although the ranges of L. greeri and L. leonis are separated by ~270 km, the dorsal patterns of some individuals of the highly polymorphic L. leonis are similar to those seen in L. greeri. Lampropeltis greeri differs from L. leonis in lacking pronounced pattern polymorphism (with the exception of the population from Sierra del Laurel, Jalisco, where modest levels of pattern variation are evident), the snout/head color matches the body ground color (only in some individuals of L. leonis), the presence of postocular black markings (rare in L. leonis), and the lack of ontogenetic color pattern change (often pronounced in some pattern types of L. leonis) (Figs. 23, 24) [from Hansen & Salmon 2017; 732] |
| Comment | Synonymy: partly after HANSEN & SALMON 2017. Gehlbach and McCoy (1965), considered L. greeri to fall within the known variation of L. m. mexicana, a position Hansen & Salmon reject. Distribution: see map in HANSEN & SALMON 2017: 722 (Fig. 17). Not in Nayarit fide WOOLRICH-PIÑA et al. 2016 (who only report L. mexicana). Not in Durango fide Lemos-Espinal (2018). |
| Etymology | Dedicated to Mr. J. Keever Greer, one of the collectors of the holotype (Webb, 1961). |
