This 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.

Phylogenetic hypothesis of species in Eunica from Jenkins (1990)
Containing group: Epicaliini

Introduction

The genus Eunica was extensively revised by Jenkins (1990), who also included a cladistic analysis of 55 morphological characters. Species of Eunica are found mainly in South America with a few species found in Central America and the Greater Antilles. The genus comprises 40 currently accepted species (Lamas 2004). The host plants have been recorded for only a few species, but in line with other species in Biblidinae, these are in the plant families Euphorbiaceae and Burseraceae.

Characteristics

According to Jenkins (1990) the diagnostic features of Eunica are:

  1. Male uncus with a terminal small, usually separate, extended and curved beak
  2. Male tegumen elongate and often constricted posteriorly
  3. Male gnathos reduced, narrowed or shortened, rarely with a gnathos arm and rarely fused or joined ventrally
  4. Forewing with base of costa somewhat angled
  5. Male wings black or brown usually marked or glossed with iridescent blue, females dimorphic, usually brown with white maculae or band on forewing

Discussion of Phylogenetic Relationships

The phylogenetic hypothesis for Eunica is based solely on morphological characters at the moment. The tree has a consistency index of 0.40, meaning that many of the characters are homoplasious. Clearly more data (both morphological and molecular) are needed to corroborate the relationships shown. The study by Jenkins (1990) did have several well-supported results. First, he showed that the species Eunica cuvierii (previously placed in the monotypic genus Libythina) belongs in Eunica. Several of the clades in the tree above are supported by unique synapomorphies.

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.
