Reproductionoviparous. 
TypesHolotype: AMNH 55362 (not 533362), a female 
DiagnosisDefinition: A black coral snake with a transverse series of white spots that form interrupted bands around the body, poorly outlining the black bands between them. Red bands are absent or found only on the venter (Roze 1996: 193).

Description: Males have around 205 and females have 221 to 225 (223.0) ventrals; subcaudals around 45 in males and 33 to 38 (35.5) in females; 1+1 temporals. Examined: 1 male and 2 females, including the holotype. Head, body, and tail are all black above with small white spots that form crossbands. A few white spots are present on several supralabials and on few shields below. The body has a poorly defined transverse series of white spots, less than one dorsal and ventrallong. The crossbands formed by the pearly white spots define the black areas as black bands on the body and on the tail. The black bands are alternately longer and shorter and correspond to the original shorter black bands and the originallonger red bands that are now black. Ventrally, red bands can be red or white. The males have around 68 and the females have 110 to 141 (125.5) poody defined black body bands and 10 to 13 tail bands (Roze 1996: 193).
