Conoesucidae
Karl Kjer
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 boxIntroduction
Ross (1967) established the subfamily Conoesucinae within the Sericostomatidae for Australasian genera with “atrophied” scutal warts, but he did not name the included genera or offer any other diagnosis. Later, Neboiss (1977) elevated the subfamily to family status, provided a detailed diagnosis, and included 6 Australasian genera in the family, all formerly included in the Sericostomatidae. Additional sericostomatid genera have been transferred to Conoesucidae such that the family now contains a dozen genera and ca. 40 species, endemic to either southeastern Australia and Tasmania (Coenoria Mosely, Conoesucus Mosely, Costora Mosely, Hampa Mosely, Lingora Mosely, Matasia Mosely) or New Zealand (Beraeoptera Mosely, Confluens Wise, Olinga McLachlan, Periwinkla McFarlane, Pycnocentria McLachlan, Pycnocentrodes Tillyard). (From Holzenthal et al., 2007a)Characteristics
The larvae live in small, cool, fast-flowing streams where they feed on leaf litter detritus, algae, and moss. Their cases are made of sand, small rocks, plant parts, or silk; cases are tubular and only slightly curved. Adult males have shortened, membranous maxillary palps that are held out in front of the face. Ward (1995) reported that adults of a New Zealand species of Pycnocentria were common and active during hot summer days on streamside sedges, herbs, and grasses. (From Holzenthal et al., 2007a)Discussion of Phylogenetic Relationships
Holzenthal et al. (2007b) strongly place the Coneosucidae within the Sericostomatoidea, but did not find strong evidence for its relative placement within the group. The monophyly, and the relationships among genera were examined by Johanson et al. (2009).References
