Phymatocera
Globally, there are 13 species distributed across the holarctic region. In Britain the genus is represented by one species. The genus is absent from Ireland.
The three genera Paracharactus, Rhadinoceraea and Phymatocera are difficult to separate by morphological features. However, Phymatocera can be distinguished with some confidence by the presence of a prepectus, the absence of any post-genal carina and by the tarsal claws having an inner tooth.
Larvae feed on members of the Asparagaceae family.
