Type locality: "Vivero Rancho Teja, 3 km east of Ixtlán de Juárez, Oaxaca, Mexico, 2370 m." [17˚20'N, 96˚29'W].  
TypesHolotype: AMNH 103118, a 557 mm male (B. Hallberg, 13 July 1968). 
DiagnosisDefinition: A single-banded coral snake with a black snout and a large yellow parietal band and without any black tips on red scales, or only a very few; the red bands have brownish overtones. The nuchal band covers the parietal tips and the males have no supraanal tubercles (Roze 1996: 201).

Description: Males have 203 to 208 (205.5) and females have 218 to 223 (222.3) ventrals; subcaudals 45 to 47 (46.0) in males and 35 to 37 (35.8) in females. Examined: 2 males and 4 females, which are the only known specimens, including the holotype.
The snout is black up to the frontal, followed by a yellow parietal band. The nuchal black band touches and covers the tips of the parietals. Below, the chin is yellow, but the first three infralabials and the anterior part of the chin shields are black. The black body bands are 4 dorsals and 3 to 4 ventrals long. The red bands are 3 to 4 dorsals long, usually immaculate or with a few black tips, but with brownish overtones. The yellow bands are 1 ventral and 1 dorsal long. On the tail the bands are only black and yellow and the black bands are twice as long as the yellow bands.
The males have 23 to 24 (23.5) and the females have 26 to 28 (27.0) black body bands. On the tail, the males have 7 and the females have 5 or 6 black tail bands(Roze 1996: 201).
