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
Schmid (1982) revealed the considerable diversity and widespread distribution of the family in a monograph devoted to it. The family status of Xiphocentronidae has generally been recognized since then. Schmid transferred several genera to the family and established the current taxonomic infrastructure, including the establishment of 4 new genera. His work included some 93 species, 73 newly described, or over half the total of about 140 now known for the family. When the larva of Xiphocentron was described by Edwards (1961), he recognized its close similarity to larvae of Psychomyiidae (as currently defined) and proposed that Xiphocentronidae should probably be synonymized with it. Larvae of both families have a similar overall appearance, with stout body and short legs, and a modified prothoracic trochantin, although that of Xiphocentronidae is less hatchet-shaped and partly membranous basally. (From Holzenthal et al. 2007).
In an analysis of 70 morpholigical characters, Frania and Wiggins (1997) found Xiphocentronidae to be sister to the Psychomyiidae. Kjer et al. (2001) confirmed this in their combined analyses, as well as four independent partitions. The combined analysis of Holenthal et al. (2007b) also showed this relationship.
