Prodoxoides asymmetra Nielsen and Davis

Olle Pellmyr
Containing group: Prodoxidae

Adult Characteristics

Adult depicted in Nielsen & Davis 1985. Wing expanse 9-13 mm. Sexes similar, with forewings in different shades of pale to medium brown, with golden lustre. The single species of the genus is characterized by an asymmetric juxta in the male, a strongly developed pecten at the antennal base, and a V-shaped tentorium. All features are depicted in Nielsen and Davis 1985.

Comparison with Similar Species

This rather unobtrusive species is the only known prodoxoid in the southern hemisphere. Females can be distinguished from the family synapomorphies, in particular the paired stellate signa, and the male is distinguished from all other prodoxids by an symmetric juxta.

Host, Oviposition, and Larval Feeding Habits

All known specimens were swept during the day or early evening around the myrtaceous shrubs Amomyrtus luma and Myrceugenella apicaulata, and the former was suspected to be the host. Nielsen and Davis suggested that the larva may bore inside buds or twigs of its host.

Geographic Distribution

P. asymmetra is known from bordering regions of Chile (Prov. Osorno) and Argentina (Prov. Rio Negro).


In temperate Valdivian rainforest and humid Nothofagus-Chusqua forest at 350-77 m elevation.


Holotype in USNM.

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.
