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: Plenitentoria

Introduction

This is a Northern Hemisphere family found in both the Old and New Worlds. Ulmer (1903) originally established this group as a subfamily of Sericostomatidae. It now contains 6 genera and a little over 100 species. Three of these genera are monotypic: Adicrophleps Flint (Nearctic), Amiocentrus Ross (Nearctic), and Dolichocentrus Martynov (southeastern Siberia). Eobrachycentrus Wiggins (Japan and western North America) contains only half a dozen species. Brachycentrus Curtis (ca. 30 species) and Micrasema McLachlan (ca. 75 species) are both widespread across the Holarctic and Oriental regions. Larvae construct cases from plant or rock materials, and some species use silk alone for part of the case. Several genera build 4-sided cases. The family is ecologically diverse. They inhabit running waters, but may be found in slow-flowing marshy channels. Some genera feed on aquatic moss; others are filter-feeders. Larvae of some Brachycentridae have rows of hairs on the middle and hind legs used for filtering food particles from currents. Some North American species of Brachycentrus can be found in thermal streams with temperatures as high as 34°C that smell strongly of hydrogen sulfide (Wiggins 2004). (From Holzenthal et al., 2007)

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.
