DistributionTrinidad, E Venezuela (incl. Carabobo), C Guianas / Guyana, Brazil (Roraima, Amapá, Amazônas, Pará fide Costa & Bérnils 2018; Nogueira et al., 2019)

Type locality: “Tunapuna, Trinidad”  
TypesHolotype: FMNH 34472, male; paratypes: Carnegie Museum 7925 (from Cumanacoa, Sucre, Venezuela) and INHS (= UIMNH) 22626, adult male, from Hoso Rora, near Morawhanna, Northeast District, British Guiana 
DiagnosisDiagnosis. Differs from the typical subspecies in having the white rings densely spotted with black above and the red rings moderately spotted; in having fewer ventrals, 219 — 226 in males, 226 — 239 in females (Table 1); and, perhaps, in reaching a larger size (Table 5). To distinguish the species lemniscatus from other coral snakes with which it is associated in Venezuela, the Guianas or Trinidad, reference may be made to the key in Burger 1955. 
CommentSynonymy: Wallach et al. 2014: 448 listed this species as synonym of Micrurus lemniscatus. 
EtymologyFrom 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).
