Connatichela artemisiae
Anderson, 1984
Connatichela artemisiae is a weevil to the Yukon Territory, Canada, and the sole member of its . The species was described in 1984 and represents a distinctive lineage within the Entiminae, characterized by unique tarsal claw . Fossil evidence indicates a broader Pleistocene distribution across Beringia, with modern restriction to the Yukon likely reflecting post-glacial loss. have been documented in association with small Artemisia species.

Identification
Distinguished from all other leptopiine by connate (joined at base) tarsal claws. Additional diagnostic features include absence of metepisternal , absence of on antennal funiculus, and presence of broad scales on antennal scape. Male and female genitalia structure provides further separation from related . The combination of these traits is unique to Connatichela within the Byrsopagini.
Habitat
Currently restricted to dry steppe-tundra or similar open, arid in the Yukon Territory. Historical distribution during the mid-Wisconsinan included comparable habitats across western Beringia.
Distribution
to Yukon Territory, Canada. Fossil material of mid-Wisconsinan age from the Yukon Territory, extreme western Northwest Territories, and Alaska indicates a formerly broader Pleistocene range across Beringia.
Host Associations
- Artemisia - association found with plants of a small ; feeding relationship not explicitly confirmed
Behavior
have been observed in association with vegetation of small Artemisia . No other behavioral details have been documented.
Similar Taxa
- Other Byrsopagini generaConnatichela is distinguished by connate tarsal claws and genitalia structure; related have free tarsal claws and differ in antennal scaling and patterns.
More Details
Paleoendemism
The exemplifies a relictual distribution pattern, with fossil evidence documenting substantial range contraction since the Pleistocene. This pattern is attributed to the reduction of arid steppe-tundra following the Wisconsinan glaciation.
Taxonomic history
The Connatichela was erected simultaneously with the description in 1984. Its phylogenetic placement within Entiminae remains unresolved.
