Containing group: Homilopsocidea


The family Bryopsocidae includes two species in the genus Bryopsocus that are known only from New Zealand.  The family was originally described within the family Philotarsidae, which it closely resembles.

Bryopsocids are medium sized bark lice, 2-3 mm in length. They inhabit moss in damp forests. 


How to Know the Family

Discussion of Phylogenetic Relationships

Specimens of Bryopsocus are rare.  The genus was included in a comparative morphological analysis, which placed it within superfamily Perisocidea (Yoshizawa 2002).  Bryopsocus has not been studied using molecular techniques.

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.
