Ornate Coralsnake

Micrurus ornatissimus is medium-sized for its genus. Adults usually have a total length (tail included) of 45–70 cm (18–28 in). The maximum recorded total length is 85 cm (33 in). Like many New World coral snakes, the color pattern consist of red, black, and white rings. The red rings are slightly wider than the black rings. The black rings are not arranged in triads. The number of black rings on the body is very variable, from 38 to 67. The white rings, which separate the red from the black, are reduced to series of pearly dots, each dot covering half a dorsal scale. The white rings are complete ventrally, each covering one ventral. Males have 201–211 ventrals and 47–52 subcaudals, and no supraanal tubercles. Females have 218–230 ventrals and 33–38 subcaudals.

Specimens of Micrurus ornatissimus have been identified in regions of the Amazonian slopes of the Andes of southern Colombia, eastern Ecuador, and northern Peru.

The specific name, ornatissimus, is Latin for "very ornate". The specific name of Boulenger's synonym, buckleyi, is in honor of Clarence Buckley (1839–1889) who collected over 10,000 biological specimens in Ecuador for the British Museum.
