Type locality: Longleaf Pine Highway, 0.5 miles west of Hwy 119, Natchitoches Parish, Louisiana, USA
|Types||Holotype: LSUM 55922|
|Diagnosis||Description: Elaphe slowinskii is very similar to E. guttata in body shape and head markings, but is distinguished from the nearby southern E. guttata by lacking the brighter yellow and red dorsal color patterns (Vaughan et al., 1996). They generally have a grayish, brown, or tan ground color with dark red, maroon, or brownish blotches. In some specimens, the dark brown ground color may obscure the dorsal color pattern. The belly pattern may be checkered, but often displays smaller and more evenly paired rows of ventral blotches with some degree of peppering across the cream ventral ground color. The black margin surrounding the dorsal blotches at midbody tends to occupy only 25–50% of each scale in E. slowinskii, but usually occupies an entire scale in E. guttata. Some specimens of E. slowinskii appear similar to E. emoryi. However, most E. emoryi tend to be gray|
with dark gray or olive colored blotches and often have more sparsely patterned bellies than E. slowinskii (Vaughan et al., 1996).
The number of combined dorsal body and tail blotches in E. slowinskii (mean=48, range=42–56, n = 17) are greater than that of E. guttata (mean=38, range=34–47, n = 18) and less than that of E. emoryi (mean=58, range=48–65, n = 19). The width of dorsal blotches at midbody,measured in number of scales, in E. slowinskii (mean=13, range=10.5–15, and n = 17) is less than E. guttata (mean=16.0, range=13–19, and n = 18) and greater than E. emoryi (mean=12, range=9–15, and n = 19). The length of dorsal blotches at midbody, measured in number of scales, in E. slowinskii (mean=4, range=3–5, and n = 17) is less than E. guttata (mean=6, range=5–7, and n = 18) and greater than E. emoryi (mean=4, range=2.5–5.5, and n = 19).
