The world species of Oodera Westwood, 1874 (Chalcidoidea: Pteromalidae: Cleonyminae: Ooderini) are revised. We examined 115 specimens of this rarely collected genus and based on morphological characters assign 110 specimens to 20 recognised species, of which the following ten are described as new: Oodera circularicollis sp. n. (Morocco), O. felix sp. n. (Central African Republic), O. fidelis sp. n. (Vietnam), O. florea sp. n. (Thailand), O. heikewernerae sp. n. (Botswana and South Africa), O. leibnizi sp. n. (Papua New Guinea, Malaysia and Phillippines), O. mkomaziensis sp. n. (Tanzania), O. namibiensis sp. n. (Namibia), O. niehuisorum sp. n. (Egypt and Israel), and O. srilankiensis sp. n. (Sri Lanka). Oodera monstrum Nikol’skaya, 1952, syn. n., is synonymised under O. formosa (Giraud, 1863). Five specimens could not be assigned to species and are treated as Oodera sp. Redescriptions are provided for all previously described valid species. Oodera albopilosa Crosby, 1909 is excluded from Oodera and transferred to Eupelmus Dalman, 1820 (Eupelmidae) as E. albopilosa (Crosby, 1909) n. comb. Oodera rufimana Westwood, 1874 and O. obscura Westwood, 1874 are treated as nomina dubia because we were unable to locate type specimens and the original descriptions are not sufficiently informative to clarify the taxonomic status of these names. Several specimens from North America are identified as introduced specimens of the European species O. formosa. We provide images and diagnostic characters for all 20 included species and an identification key to species.

Keywords: Taxonomy, parasitoid wasps, identification key, new species

Record localities of O. pumilae Yang and O. regiae Yang are not exact but placed in the centre of the respective Chinese province from which the species was recorded.
