Introduction

The genus Eohomopterus contains four described species; two extant species, E. aequatoriensis (WASMANN, 1899) from Ecuador and E. centenarius LUNA DE CARVALHO, 1960 from Brazil, and two fossil species, E. paulmuelleri NAGEL, 1987 and E. poinari NAGEL, 1997, both from Dominican amber. These four species are known only from their respective holotype specimens. Eohomopterus is one of three extant paussine genera that contains fossil species.

  proepipleura and proepisternum glabrous
  legs with tarsomeres 1 and 4 markedly reduced and tarsomeres 2 and 3 expanded
  tarsomeres 2 and 3 expanded with two patches of adhesive setae underneath and a glabrous midline, pubescent patch on outer margin of midline larger than on inner margin
  tibia with dorsal apical angle expanded
  abdomen markedly broader than pterothorax
  aedeagus lies on its right side within the abdomen, the median lobe with apex directed to the right and the apical orifice on the right

Discussion of Phylogenetic Relationships

Eohomopterus and its Old World counterpart, Carabidomemnus, together comprise the paussine subtribe Carabidomemnina which is thought to be the sister group of the remaining extant members of the tribe Paussini (Nagel 1987).

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.
