| Distribution | USA (S Iowa, Missouri, Arkansas, Louisiana, Mississippi, Alabama, Oklahoma; isolated record in NW Kentucky. Intergrades with splendida from Nebraska to Texas) Type Locality: ‘Valley of the Mississippi’ (Holbrook 1842), restricted to Hot Springs, Arkansas (Schmidt 1953). |
| Reproduction | oviparous |
| Types | Holotype: unknown (fide PYRON & BURBRINK 2009). |
| Diagnosis | Diagnosis: The Speckled Kingsnake (L. holbrooki) is a medium- to large-bodied constrictor with a maximum adult size of 183cm and a mean adult range of 90–122cm (Conant & Collins 1998). Scales are smooth, anal plate single, and midbody scale rows number 19–25 (Blaney 1977). Ventral scales number 197– 222 in both sexes, with subcaudals ranging from 46–59 in males and 37–51 in females (Blanchard 1921; Blaney 1977). The Speckled Kingsnake occurs west of the Mississippi River, from Iowa and Nebraska in the north to the Gulf Coast, and west to west-central Texas (Fig. 2). The majority of the range of L. holbrooki is characterized by the ‘speckled’ pattern, which consists of a black ground color, with a white or yellow speckle in the center of each scale, and very occasionally a faint trace of dorsal crossbanding (Fig. 3). Large geographical areas harboring at least superficial morphological intermediacy between the Speckled Kingsnake and the Desert lineage in west central Texas are apparently inhabited only by the Speckled Kingsnake, suggesting that such color pattern variation may be due to phenotypic responses to ecological gradation, rather than hybridization or introgression (Pyron & Burbrink 2009c). The precise western extent of the range of L. holbrooki is unclear, but ecological niche modeling predicts that the range extends approximately to the Pecos and Rio Grande River drainages (see Fig. 4 in Pyron & Burbrink 2009c; Fig. 2) [from PYRON & BURBRINK 2009]. |
