We report the first record in Colombia, and the first find since 1966 of Imantodes
phantasma Myers, 1982, based on 3 specimens from Unguía municipality, department of
Chocó, Colombia. The present record adds a new snake species to the country’s list
and extends this species’ documented distribution by approximately 65 km, in a straight-line
northeast from its nearest previously known Panamanian locality. This is the first
report of this species for more than 50 years since its description.
