Ischnopterapion (Ischnopterapion) plumbeomicans (Rosenhauer, 1856)

This species was included as an inhabitant of the Canary Islands by MACHADO & OROMÍ (2000) on the basis of a record of Apion westwoodi in HEYDEN (1875) which was identified by M.A. Alonso-Zarazaga as referring to this species. Heyden referred to a dozen specimens taken at Tafira (C) on 22 April 1872. There are no other references to this record, the species being omitted from the accounts of LINDBERG & LINDBERG (1958) and BRITO & OROMÍ (1986).
