Diagnosis 
CommentIllustrations: Wright and Wright, 1957; Conant and Collins 1991; Ashton and Ashton, 1982, among many others.

Synonymy (edwardsii): “Merrem (1820: 136) lists Coluber (Natrix) edwardsii as his 195th species and attributes it to a synonymy of two authors: Edwards Gleanings Nat. Hist. 1764: 290, pl. 349, and Shaw Gen. Zool. 1820: 553. The description is taken verbatim from Shaw and presumably also from Edwards’ descriptions (which were not binomial). Shaw provides the first binomial description (Coluber torquatus), which is a different species from the torquatus of Lacépède. The locality is Pennsylvania so that restricts the variety to what is known as D. p. edwardsii; however, the authorship belongs to Shaw (1802), not Merrem (1820). This is a case that should be appealed for suppression by the ICZN or considered a nomen oblitum, which I believe no longer has acceptance. Unless, of course, torquatus Shaw, 1802 can be considered preoccupied by torquatus Lacépède, 1789 (which has been officially rejected by the ICZN). Before 1987 it was acknowledged that Lacépède’s name was available but Opinion 1463 changed that and made all names except three (madagascariensis, piscivores, reticulata) unavailable. This means that edwardsii 1820 is a junior synonym of torquatus 1802.” (V. Wallach, pers. comm., 17 May 2019).

Subspecies: D. amabilis, modestus, occidentalis, pulchellus, similis, and vandenburghi appear to be nearly indistinguishable and therefore are of questionable validity (C. Feldman, cited in CROTHER 2000). Using mtDNA, Fontanella et al. (2008) identified fourteen lineages of Ringneck Snakes but declined to recognize them as distinct (sub-) species, pending the acquisition of additional data from Mexican populations and the evaluation of nucleic molecular data for the entire complex. Fontanella et al. 2021 found that D. p. similis and D. p. modestus may be synonymous but they didn’t formally synonymize them.

The following distinct species are recognized by Joe Collins (CNAH): D. acricus, D. amabilis, D. arnyi, D. docilis, D. edwardsii, D. modestus, D. occipitalis, D. pulchellus, D. punctatus, D. regalis, D. stictogenys, D. texensis, based on known type localities (as they appear in Blanchard, 1942, Stejneger and Barbour, 1943, and Schmidt, 1953, plus information generously provided by Van Wallach, Walter E. Meshaka, Jr., James N. Layne, Travis W. Taggart, and Curtis J. Schmidt, pers. comms.; also see Figures 3 & 5 in Fontanella et al. for lineage designations).

The three specimens from Islas Todos Santos were originally described as D. anthonyi and differ from snakes of the adjacent peninsula in that the body tends to be more stout or robust (Blanchard 1942) and the neck ring obscure with poorly defined edges (Van Denburgh and Slevin 1923). Subsequent authors have considered it to be D. punctatus [GRISMER 2002].

Distribution: For subspecies map see Californiaherps.com

Taxonomy: Has been assigned to the family “Xenodontidae” by POTTS & COLLINS 2005 and other authors.

Mimicry: Diadophis punctatus mimicks Micrurus elegans (TORRE-LORANCA et al. 2006).

Diet: With the exception of the southwestern populations that feed exclusively on reptiles (Gehlbach, 1965), ringnecks have generalist diets, preying on salamanders, earthworms, reptiles and insects (Blanchard, 1942; Fitch, 1975; Blanchard et al., 1979; Stebbins, 1985; Conant and Collins, 1991).

Type species: Coluber punctatus LINNAEUS 1766: 376 is the type species of the genus Diadophis BAIRD & GIRARD 1853.

Genome: Westeen et al. 2023 
EtymologyNamed after the Latin word punctum, meaning "spotted" (Lemos-Espinal & Dixon 2013).

The generic name is derived from the Latin words diadem , meaning "headband" and ophis, meaning "snake."

The subspecies acricus is named after the Greek a (for no) and “krikos” for ring, referring to the “ringlessness” of the form.

The subspecies amabilis, is named after Latin amāre and amārī (“to love” and “to be loved”) +‎ -bilis (“-able: able or worthy to be”) meaning "lovely, attractive, pleasant," a reference to overall beauty and attractiveness of the subspecies.
