| Diagnosis | Diagnosis: Micrurus diutius can be distinguished from all other triadal species of Micrurus by the following combination of morphological characters: black snout (rostral, internasals, anterior border of prefrontals, most of nasals, and 1–2 supralabials); white preocular transverse band covers most of prefrontals, anterior border of supraoculars, most of preoculars, and 1–2 supralabials; black cephalic cap includes most of frontal, supraoculars, postoculars, anterior 1⁄3 of parietals, 1⁄3–1⁄2 of temporals, and 2–3 supralabials; remainder of the head red, with or without black-tipped scales; venter of head red; irregular black markings on gulars, and infralabials highly variable; 1st triad separated from parietals by 2–7 scales; middle black ring slightly longer or same length as outer ones; white rings usually shorter than outer black rings; red rings shorter than entire triad or even middle black ring; red and white rings usually black-tipped, but with tendency to a less melanic pattern (Fig. 43C); and 6–16 body triads and 1 1⁄3 –12⁄3 tail triads (Pires et al. 2021: 69).

| Comment | Synonymy: Wallach et al. 2014: 448 listed this species as synonym of Micrurus lemniscatus. |
| Etymology | From the latin “diutius”, meanning too long. From the point of view of potential victims, a meter-long venomous snake is certainly too long (Burger 1955: 40). |
