Diagnosis: Micrurus diana is a triadal coralsnake with a white snout, including the prefrontals, preoculars, anterior 3-4 supralabials (all black bordered or with irregular black markings) and the anterior 3 of the frontal and supraoculars. The head is black with the parietals showing very little reduction on the sides (Fig. 24). All temporals, posterior 3-4 supralabials are red (immaculate). Inferiorly, the chin is white from mental to anterior genials and 3 anterior infralabials. Some irregular black markings may be present, and the remainder is red. The first triad is always fused with the posterior end of the parietals (fixed character). The white rings are longer than the black ones which tend to be semiequal in length (Table 2). The white rings are mildly black-tipped, and the red rings are immaculate. Triads range from 10 to 11 (Table 1, from Silva & Sites 1999: 170).
|Etymology||As the original description states: "Dedicated to' Diana, the goddess of forests, animals and moon who should be adored and invoked to protect the endangered nature, particularly animals."|
