Mexico (Coahuila)

Type locality: “America”

amaura (invalid): SW Arkansas, SE Oklahoma, E Texas and Louisiana. Type locality, original entry of type reads "?Mississippi," restricted by Schmidt (1953) to the vicinity of New Orleans, Louisiana. Williams (1978) suggested that the type locality be considered as unknown, inasmuch as the characteristics of the holotype do not agree with data taken from specimens from New Orleans and vicinity.

celaenops (invalid): USA (SW Texas, E New Mexico, SE Arizona). Type locality: Mesilla Valley, New Mexico.

gentilis: Kansas, W Oklahoma, E Colorado, Texas panhandle, C/SW Nebraska, C/W Kansas; Type locality: "north fork of the Red River, near Sweetwater Creek, Wheeler County, Texas."

multistrata (invalid): USA (C/NW Nebraska, S Montana, SW North Dakota, N/C Wyoming); Type locality: "Fort Lookout, Nebraska," now in Lyman County, South Dakota.

syspila: USA (Nebraska, Oklahoma, Kansas)

taylori (invalid): C/NE Utah, W Colorado, N Arizona; Type locality: "from approximately 2 miles north of Alpine, Utah County, Utah."  
Reproductionoviparous. KREUTZ (2005) reports hybrids between E. guttata and Lampropeltis getulus californiae, between E. guttata and L. pyromelana, and between E. guttata and L. triangulum sinaloae/nelsoni! 
TypesHolotype: lost or never designated (fide WILLIAMS 1994)

Lectotype: USNM 131737 (old catalog number 1852 or 1853), adult male (designated by BLANCHARD 1921) [gentilis]

Holotype: USNM 1842, young male [multistriata]
Holotype: BYU 10533, adult female [taylori] 
DiagnosisDiagnosis: Lampropeltis triangulum differs from L. rutheni, L. mexicana, and L. alterna in having the head less distinct from the body. In addition, this species differs from L. ruthveni (within the range of the latter) in having less uniform red rings, often obscured by black pigment middorsally. Another difference between L. triangulum on the one hand, and ruthveni and L. mexicana on the other, is that in the latter two the black rings are edged with a paler color (usually a pale lime green). Lampropeltis ruthveni has a lower ventral count (182-196) than sympatric L. triangulum (196-221). All members of the mexicana group tend to have considerable gray in the body colors, such is not so in triangulum, except some triangulum in the northeastern United States. Lampropeltis triangulum differs from L. zonata in that the white rings widen laterally in the former; from L. pyromelana in having a black, black and white, or red snout, rather than white. Lampropeltis pryomelana has 46-85 white rings on body, more than L. triangulum (10-32). Both L. pyromelana and L. zonata have a higher ventral scute number (213-238, and 194-227, respectively) than any of the adjacent western United States members of L. triangulum (174-208). Lampropeltis triangulum differs from both L. calligaster and L. getula in having an alternating pattern of white (yellow), red and black rings or blotches, the latter reaching the ventrals or nearly so, and in having the posterior two maxillary teeth longer and stouter than the preceding teeth.

CommentSynonymy after PETERS & OREJAS-MIRANDA 170, WILLIAMS 14, and RUANE et al. 2014, and Chalmers et al. 2022 (although they did not comment on synonyms beyond moving gentilis back to triangulum as subspecies).

Distribution: L. gentilis is not in Nuevo León but annulata is, fide Nevárez-de los Reyes et al. 2016. See map in Chalmers et al. 2022: 359 (Fig. 1).

Distribution: revised after genetic analysis of Ruane et al. 2014. Previously, this species was also reported from Mexico (e.g. Jalisco, San Luis Potosí, Nuevo Léon, Coahuila, Nayarit, Sonora etc., e.g. by Lemos-Espinal et al. 2016), south to Colombia (Valle del Cauca, Valencia et al. 2014).

Subspecies: Lampropeltis triangulum elapsoides (HOLBROOK 1838) has been elevated to species status. Ruane et al. (2014) elevated a number of subspecies of L. triangulum to full species and synonymized the remaining subspecies as follows: Subspecies synonymized under L. micropholis include L. t. gaigeae and L. t. andesiana. Subspecies synonymized under L. abnorma include L. t. blanchardi, L. t. hondurensis, L. t. oligozona and L. t. stuarti. Subspecies synonymized under L. polyzona include L. t. arcifera, L. t. conanti, L. t. campbelli, L. t. nelsoni, L. t. smithi, and L. t. sinaloae. Subspecies synonymized under L. annulata include L. t. dixoni. Subspecies synonymized under L. gentilis include L. t. celaenops, L. t. multistriata, L. t. taylori, L. t. amaura (in part), L. t. syspila (in part) and L. t. annulata (in part). Subspecies synonymized under L. triangulum include L. t. syspila (in part) and L. t. amaura (in part). L. gentilis and triangulum have a broad contact zone with little reproductive isolation which does not warrant recognition as full species fide Chalmers et al. 2022. Basett & Pandelis (2024) did not accept the separate species model of Ruane et al. 2014 either.

Nomenclature: LACÉPÈDE’s name conserved through ICZN opinion 1463. Coluber doliatus was suppressed via Opinion 804. The original spelling of multistriata was apparently a misspelling of multistrata, fide Cope 1861: 566, Williams 1994: 7.

Mimicry: Lampropeltis triangulum mimicks Micrurus bernadi, M. limbatus and M. diastema (TORRE-LORANCA et al. 2006).

NCBI taxonID: 165043 [gentilis] 
EtymologyThe name triangulum is derived from the Latin meaning "triangle," in reference to the shape of the anterior edge of the first blotch.

The name gentilis is derived from the Latin, meaning "of the same race or clan", presumably in reference to its relationship to other members of the species.

The name celaenops may be derived from the Greek word celaeno, which means "black or dark," and the ending -ops, meaning eye.

The name multistrata is derived from the Latin multus, meaning "many," and the Latin stratum, meaning "layer," apparently in reference to the number of dorsal scale rows present.

The name taylori isa patronym honoring Edward H. Taylor, designated "our friend and teacher" by describers.
