Heliconius cydno is a polytypic species ranging from southern Mexico to western Ecuador, with a number of closely-related entities (including H. pachinus, H. heurippa, H. timareta and H. tristero) that have been described as separate species but may be differentiated geographical races or the results of introgressive hybridization. Patterns of gene flow between races of H. cydno and races of its close relative H. melpomene are the subject of much current research (e. g., Mavarez et al. 2006).

Geographical Races

Like many species of Heliconius, H. cydno exhibits discrete geographical variation in its wing coloration, with relatively narrow zones of hybridization between adjacent geographical races. The following subspecific names are recognized by Lamas (2004):

The following taxa are closely-elated to H. cydno and may represent geographical races/subspecies rather than distinct species:

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
