Oh my goodness! Unless you are a Tree of Life developer, you really shouldn't be here. This page is part of our beta test site, where we develop new features for the ToL, often messing up a thing or two in the process. Please visit the official version of this page, which is available here.

Stygini Ehrlich 1958

Styx infernalis Staudinger 1876

Andrew V. Z. Brower
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.

Adults are pale grayish white with brown wing veins, resembling small Parnassius butterflies (Papilionidae).

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.
