Stygini Ehrlich 1958

Styx infernalis Staudinger 1876

Containing group: Riodinidae


A monotypic tribe from the highlands of Peru. For many years, Styx was considered to be a "missing link" among butterflies, perhaps shedding light on the relationship among riodinids, lycaenids and nymphalids. It has now been shown based on DNA evidence (Wahlberg et al. 2005) to be a riodinid.

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, 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.
