TypesHolotype: INHS (= UIMNH) 40369 604; W. H. Davis, W. Z. Lidicker, and J. R. Winklemann; July 16, 1956. 
DiagnosisDefinition: A single-banded coral snake with black, red, and white or yellow bands in which the females have several black bands interrupted ventrally. It has a black snout and a white parietal band followed by a black nuchal band. The red dorsal scales have small black tips, but not on all scales. Males have supraanal tubercles (Roze 1996: 209).

Description: Males have 202 to 207 (204.8) and females have 210 to 218 (214.4) ventrals; subcaudals 47 to 53 (48.7) in males and 36 to 42 (38.3) in females. Usually 1+2 temporals, at least on one side. Examined: 7 males and 5 females, including the holotype.
The snout is black, including most of the frontal and anterior part of the parietals, followed by a yellow or white band that includes 3 or 4 supralabials. Below, the head is white with the mental and first infralabials black and with some black borders on several additional shields. The black nuchal band covers the tips of the parietals, 4 to 5 dorsals, and 3 to 4 ventrals, including the tips of the second pair of genials. The single black body bands are 2 to 3 dorsals and ventrals long. In females, several black bands are interrupted ventrally. The yellow or white bands are barely 1 dorsal and ventral long. The red bands are 2 or more times longer than the black bands. They are 7 to 9 dorsals and ventrals long, with small black tips present on several, but not all, dorsals. Only black and white bands are on the tail; the first are 2 or 3 times longer than the white bands.
The males have 17 to 22 (18.6) and the females have 21 to 24 (23.2) black body bands. In females only 3 to 10 bands are complete. Both sexes have 5 to 7 black tail bands (Roze 1996: 209).
