Remarks
First record from
Denmark
. It is broadly accepted that this species exists in two “growth forms” or “morphotypes” related to the sex of the host and growth position on the body. The typical horned form grows under the margins of the pronotum or neighbouring areas in females, and the not horned form grows between the anterior or medium claws in males.
