Help with Araecerus

Perhaps I have lostn a point somewhere.

If I understand well,
a) Araecerus has been described by Schonherr in 1826 with coffeaea
Fabricius, 1801 as type species.
b) Degeer has described fasciculatus in 1775.
c) both species are synonyms.
d) the type species of Araecerus is Araecerus fasciculatus DEGEER, 1775.

Is this wrong ?
