Pareuchontha Miller 1989 TS = Stenoplastis grandimacula

James S. Miller and Andrew V. Z. Brower
Containing group: Dioptini


Miller (1989) erected this genus for species removed from Euchontha, and as of 2009, he is no longer certain that the two genera are sister taxa. Most members of Pareuchontha occur on the eastern slopes of the Andes from Ecuador to Bolivia, but P. fuscivena occurs on the western slope in Colombia. Most specimens have been collected puddling on rocks in rivers.


Members of Pareuchontha may be distunguished from Euchontha by their shorter labial palpi and narrower wings. Both genera exhibit small eyes with a scaleless gena, and well developed forewing stridulatory organs (in males).

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.
