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.

Containing group: Trogiomorpha


The family Prionoglarididae contains 3 genera and 7 species that have been collected in Europe, Namibia, Afghanistan, and the southwestern US.

Three species of prionoglarids are known from North America, all in the genus Speleketor.  These are medium-sized bark lice with pale bodies and sparse hairs on wings and body, but no scales.  Speleketor species have been collected in caves, on dead palm leaves, and at lights.



General Characters

How to Know the Family

Discussion of Phylogenetic Relationships

The monophyly of family Prionolarididae is supported by two morphological characters: the simplified or reduced lacinia of adults, and the highly specialized structure of the male genitalia (described under Characteristics).  Molecular analysis also supports monophyly of the familiy based on the sister relationship of genera Prionogalris and Speleketor (18S & Histone3 nDNA, 16S rDNA; Yoshizawa et al. 2006).

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.
