|Distribution||Mexico (Oaxaca, Chiapas), W Guatemala|
Type locality: Finca El Cipres, Volcan Zunil, Suchetepequez, Guatemala.
|Types||Holotype: MCZ 22135; 17 additional paratypes in NMBA, SMF, MNHN, AMNH, USNM, and MCZ according to the original description. Paratype: ZSM 2263/0|
|Diagnosis||Diagnosis [altifasciatus]: A coral snake with black, yellow, and red rings; well-developed supra-anal tubercles in adult males; black rings few, 6 to 9, and broad, covering 6 to 11 ventrals; red rings very broad, covering 17 to 26 ventrals; scales in red rings uniformly black-spotted; yellow rings well developed; black rings on tail 2-3; temporals invariably 1-1; very rarely a few caudals entire; ventrals 192-197 in males, caudals 50-55; 204-214 and 40-46 in females.|
Closely allied to the nigrocinctus group, but apparently specifically distinct and within the range of M. n. zunilensis; no other coral snake has such broad black and red zones. Its nearest ally may prove to be M. nuchalis of Oaxaca [from SCHMIDT 1933].
Diagnosis [nuchalis]: A coral snake with black, yellow, and red rings, the black rings not arranged in triads, or with a narrow black accessory ring bordering the red zones next to the yellow; supra-anal tubercles distinct in males; ventrals 201-208, caudals 40-51 in males, 203-209 and 37-40 in females; temporals invariably 1-1; no entire caudals recorded; black bands few, 8 to 9 in both sexes, 2-3 ventrals wide; nuchal black ring much broader; black bands on tail 2-3; scales in red zones heavily and uniformly black-spotted.
Apparently allied to M. latifasciatus of the Pacific slope of Guatemala; the coral snakes of Chiapas are unknown. It is the western most and northernmost species with supra-anal tubercles, and overlaps the range of the very distinct M. ephippifer, which, however, is only known from females [from SCHMIDT 1933].
