Calocidae

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
This family is endemic to Australia and New Zealand, established by Ross (1967) to accommodate genera originally placed in Sericostomatidae, Beraeidae, or Odontoceridae. As with other new families established in this paper, Ross gave no family diagnosis or indication of included genera. In the same paper, he placed Pycnocentrella eruensis Mosely, originally described in Beraeidae, in his newly created family Pycnocentrellidae, later synonymized with Calocidae by Neboiss (1977). The New Zealand genus Alloecentrella Wise, first described in Beraeidae and at times included in the Helicophidae was formally transferred from Calocidae to Helicophidae by Henderson and Ward (2007); their phylogenetic analysis revealed its close affinity to other helicophid genera. In its present composition, the family now contains 6 genera endemic to Australia (Caenota Mosely, Caloca Mosely, Calocoides Neboiss, Pliocaloca Neboiss, Tamasia Mosely) and 1 endemic to New Zealand (Pycnocentrella), with a total of 19 species.Characteristics
One Tasmanian species is terrestrial and lives under moss and leaf litter in wet sclerophyll forest, but others occur in small, woodland streams among plant roots and accumulations of detritus (Jackson 1998, Neboiss 1979). They construct slightly curved and tapered cylindrical cases of small rock fragments or somewhat flattened cases of 2 dorsal and 2 ventral rows of leaf material (Jackson 1998). Adults are small to rather large (forewing lengths 5-14 mm) and have dark forewings patterned with irregular white spots. In males of some genera, the antennal scape has expandable lobes and the head bears long, expandable filaments (Neboiss 1986). Taken from Holzenthal et al., 2007.Discussion of Phylogenetic Relationships
Combined analyses of Kjer et al. (2002), and Holzenthal et al., (2007b) did not place any confidence with the position of Calocidae within the Sericostomatoidea. The monophyly, as well as the relationships among the genera were examined by Johanson and Malm (2010).References
