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.
You can click on the root to travel down the Tree of Life all the way to the root of all Life, and you can click on the names of descendent subgroups to travel up the Tree of Life all the way to individual species.close box
This is a small to moderately sized family established by Ulmer (1903) first as a subfamily of Hydropsychidae, later as a subfamily within Psychomyiidae, and then as a family (Lepneva 1970), with the majority of the known diversity found in a single genus, Ecnomus McLachlan. However, this has changed in recent years as many new species and even genera have been recognized, primarily from the Australasian region. Eight genera are recognized, of which Ecnomus is the largest, with more than 260 species widespread in the Palearctic, Oriental, Afrotropical, and Australasian regions. Austrotinodes Schmid is largely endemic to the Neotropics with about 40 species, a few extending into the extreme southwestern USA. A 2nd New World genus, Chilocentropus Navás from Chile, is a nomen dubium; its type, of unknown sex, is presumed lost. The Australasian fauna has several endemic genera, each with about 10-20 species: Agmina Ward and Schefter (New Caledonia), Daternomina Neboiss (Australia, mostly Tasmania), and Ecnomina Kimmins (Australia, New Zealand, and New Caledonia). Two genera, with about 15 species total, are endemic to Africa: Parecnomina Kimmins and Psychomyiellodes Mosely. (From Holzenthal et al. 2007a)
