America, whereas _foliamorta_ occurs only in eastern Panama and in
north-central Colombia. The ancestral _boulengeri-foliamorta_ stock
probably invaded Central America in the late Pliocene and dispersed
through humid forested environments to Nicaragua. Apparently a
peripheral population established itself in the dry Pacific lowlands of
Panama. This population differentiated from _boulengeri_ of the humid
Caribbean lowlands and evolved into _foliamorta_, which subsequently
expanded its range into Colombia.
