Two genera of Korean Orthocentrinae, Gnathochorisis and Symplecis, are reviewed, and keys to species of these genera are provided here. Two new species, Gnathochorisis fuscipes Humala & Lee, sp. n. and Gnathochorisis koreensis Humala & Lee, sp. n. are described from South Korea. The current state of the taxonomy of Eastern Palaearctic orthocentrines is briefly discussed.

The Neotropical species of the genus Gnathochorisis (Ichneumonidae: Orthocentrinae) are reviewed, seven species: G. enodis sp. nov., G. khalaimi sp. nov. from Mexico, G. intercalaris sp. nov., G. punctata sp. nov., G. rufa sp. nov., G. rufithorax sp. nov. from French Guiana, and G. dilleri sp. nov. from Peru are described and illustrated, and one species G. laticincta comb. nov. is transferred from the genus Symplecis. A key to the Neotropical Gnathochorisis species is provided.
