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. andesiana: Huila (Columbia), Venezuela (Tachira, Mérida) [HR 30: 174]); Type locality,"the hills near Cali, Valle, Colombia." annulata: S Texas, S Tamaulipas to C Nuevo Léon, S ,E Coahuila (Mexico) arcifera: Morelos, Guerrero, Michoacán, Jalisco, W Querétaro (Mexico) blanchardi: Mexico (Yucatan); Type locality: "Valladolid Trail near Chichen Itzi, Yucatan, Mexico." campbelli: S Puebla, E Morelos, N Oaxaca (Mexico) celaenops: SW Texas, E New Mexico conanti: Sierra Madre del Sur in Guerrero, Oaxaca (Mexico) dixoni: S San Luis Potosí, NE Querétaro, Guanajuato [HR 30: 113] (Mexico) gaigae: mountains in Costa Rica, Panamá gentilis: Kansas, W Oklahoma, E Colorado, Texas panhandle, C/SW Nebraska, C/W Kansas hondurensis: carribbean side of Honduras, Nicaragua, NE Costa Rica micropholis: Costa Rica, Panamá, Columbia, Venezuela, Ecuador; Type locality: Panama.

| Comment | Synonymy partly after PETERS & OREJAS-MIRANDA 1970. Subspecies: Lampropeltis triangulum elapsoides (HOLBROOK 1838) has been elevated to species status. Illustrations: L. t. sinaloae is on the title page of Elaphe 3/95. Keogh (1996) could not distinguish among L. pyromelana, L. triangulum, and L. zonata. Illustration of L.t. campbelli and L.t.hondurensis in SCHMIDT (2004). Love (2012) shows a bicephalic L. t. hondurensis. Distribution: The occurrence of Lampropeltis triangulum in Venezuela was reported by Roze (1966) and subsequent workers (Lancini 1979; Kornacker 1999) as the subspecies L. t. micropholis. Barrio and Navarrete (1999) clarified the subspecies identity of the Venezuelan specimens and considered them to belong to L. t. andesiana [cited after RIVAS et al. 2012]. Reproduction: oviparous. 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! Nomenclature: LACÉPÈDE’s name conserved through ICZN opinion 1463. Size: Max. total length: 1.5 m Abundance: in Honduras: rare Lampropeltis triangulum mimicks Micrurus bernadi, M. limbatus and M. diastema (TORRE-LORANCA et al. 2006). |
