|Diagnosis||Diagnosis: Micrurus baliocoryphus is a triadal coralsnake with a white snout with most of the scales bordered by black, including the first 3-4 supralabials. Sometimes the prefrontals are completely white with a few little black markings. The head is black with (the vast majority of our sample) or without a white band between the parietals and frontal and supraoculars. The remainder of the head is red, including the posterior 3-4 infralabials with all scales black-tipped (Figs. 15-17). Inferiorly, the chin is white, ranging from the mental and first 2 infralabials to the anterior genials and first 3 infralabials. All the scales have irregular black markings with a strong tendency to melanism. The posterior part is red rarely with black markings. The triads have a fixed character of the middle black ring at least twice as long as the external ones and immaculate white rings. The red rings are always black-tipped. Triads range from 9 to 16 (from Silva & Sites 1999: 162).|
Distribution: apparently not known from Brazil (Campbell & Lamar 2004, Da Silva & Sites, 1999).
|Etymology||Greek from “bali-” meaning spotted and “coryph” meaning head; baliocoryphus, meaning snake with spotted head, alluding to the red and black head. Mesopotamicus alludes to its distribution in the Argentinean mesopotamic region in Entre Rios.|
