Boxwood Weevil (Pseudomesoxenus scrobiculatus)
The Boxwood Weevil was described in 1877; it was restricted to the island of Saint Helena in the middle of the Atlantic Ocean.
The species was obviously adapted to the endemic Boxwood (Mellissia begoniifolia (Roxb.) Hook.f.).:
“The only example of this Pseudomesoxenus which I have yet seen has been communicated lately by Mr. P. Whitehead, who found it in the rotten wood of the Mellissia begoniaefolia [Mellissia begoniifolia] on Rock-Rose Hill.” [1]

The species was not found during the latest field searches and is thought to be possibly extinct.
