Abstract
The genus
Oodera
Westwood, 1874 (
Hymenoptera
,
Pteromalidae
,
Cleonyminae
) is recorded for the first time for the Arabian Peninsula, from the Kingdom of Saudi Arabia and the Sultanate of Oman. The present study is based on specimens reared from xylophagous beetle larvae of the family
Buprestidae
(
Coleoptera
) infesting dead
Acacia
trees from Al-Dakhiliyah and Dhofar governorates in Oman and Al-Baha, Asir and Riyadh regions in Saudi Arabia. Four new species,
Oodera
arabica
sp. nov.
,
O.
omanensis
sp. nov.
,
O.
rapuzzii
sp. nov.
, and
O.
similis
sp. nov.
are described, illustrated and compared with closely related
Oodera
species. An illustrated key and the xylophagous host records of the species are also provided.
