DistributionNicaragua, Costa Rica, Panama

Type locality: Veraguas, Panama  
Reproductionoviparous 
TypesHolotype: ANSP 10113, male, collected by R. W. Mitchell 
DiagnosisDIAGNOSIS: The absence of a mental groove (fig. 11.14e in Savage 2002), the rectangular chin shields, and the relatively unspotted light rings separate this form from all other tri-colored Costa Rican snakes (Savage 2002: 597).

SIMILAR SPECIES: (1) Dipsas tenuissima is heavily streaked and spotted with dark pigment in the light rings (2)Dipsas bicolor has red bands in the light dorsal inter-spaces. (3) Sibon anthracops has red saddles in the light dorsal interspaces. (4) Other ringed species of Sibon have 26 to 45 body rings and bands. (5) Micrurus mipartitus has a cylindrical body with the head not distinct from the neck and has small, nonprotuberant eyes. See key to coral snakes, figure 11.47, and table 11.2 in Savage 2002: 597, 706). 
CommentHabitat: fully arboreal (Harrington et al. 2018).
