ChlamydoniaMichael S. Caterino
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.

This genus was described recently, along with Kanakopsis and two species of Chlamydopsis, in a paper reporting Chlamydopsinae from New Caledonia for the first time (Caterino, 2006). Superficially its members appear similar to species in the genera Eucurtiopsis and Orectoscelis. However, they exhibit many structural differences that indicate that their similarities are probably convergent. Nearly all known specimens have been collected through the use of flight interception traps, so nothing is known about their habits or possible hosts.
The species of Chlamydonia are quite varied in appearance. Many species are strongly punctured and otherwise sculptured, while others are completely smooth. Some are very setose, while others are smooth. What they all share are series of frontal tubercles on the head, usually organized in two parallel series, paired pronotal tubercles (usually two pairs), and a doubled epipleural marginal stria, with the second appearing as an arc above the metafemoral apex (when the legs are held in the resting position.)
The trichomes generally form some kind of elongate disc, with setae along the rounded edge. The length and orientation of this disc vary greatly, as do the setae along its edge. In many species the setae are short and even, while in others they may be greatly elongated, projecting upward or outward from the body.
The species level relationships within Chlamydonia were analyzed by Caterino (2006) in the paper featuring the species decriptions. The basal split in the genus is defined by the differing appearance of a median fovea on the inner surface of the trichome. While relationships depicted above are well supported for a few small groups of species, there is significant phylogenetic work still to be done in the genus. In particular, most species are known only from one sex (in most cases males), so it has not been possible to study genitalic characters in sufficient detail to include any in the analysis.
