Scea
James S. Miller and Andrew V. Z. BrowerThis tree diagram shows the relationships between several groups of organisms.
The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.
You can click on the root to travel down the Tree of Life all the way to the root of all Life, and you can click on the names of descendent subgroups to travel up the Tree of Life all the way to individual species.

close boxIntroduction
The genus Scea is mainly endemic to the eastern and western slopes of the Andes, with a few species extending into the lowlands as far as southeastern Brazil and Argentina. Most exhibit characteristic black wings with orange basal patches, but some species formerly included in the genus Cyanotricha are mainly iridescent bluish black with red dashes, and other species now removed to different genera (Notascea, Lyces) share the orange and black color pattern, probably as a result of Müllerian mimicry (the pattern is also shared by various pericopine and lithosiine arctiids).Characteristics
Most species in the genus can be recognized by the striking yellow-orange basal regions of the forewings, many with black scaling on the veins. However, there are very similar species in other dioptine genera (Notascea), as well as mimics in Geometridae and Arctiidae. The wing venation of Scea auriflamma is shown below.
Discussion of Phylogenetic Relationships
The partially-resolved hypothesis of relationships shown above is distilled from the species accounts in Miller (2009).References
