Even though non-pollinating fig wasps are essential components in tropical and subtropical habitats, yet they are poorly described in the Oriental communities. This study presented seven new sycoryctine fig wasp species associated with Ficus hirta fig trees inhabiting South China and Southeast Asia. These new sycoryctine species belong to the genera Philotrypesis, Sycoryctes, and Sycoscapter. They can be easily distinguished by their adaptive morphologies such as face sculpture, body-color, and ovipositors. An identification key is provided to differentiate between them, and the relationships with their host fig trees are also discussed. The holotypes and paratypes are both deposited in the South China Botanical Garden, Chinese Academy of Sciences, China.

An increasing number of fig trees are known to support more than one species of pollinator fig wasp (Agaonidae). This brings into question the relative importance of co-evolution, radiation and host switching in the development of this mutualistic association. The functionally dioecious Ficus hispida has a wide distribution in Asia. It supports at least three morphologically distinct Ceratosolen pollinators, one of which we describe as C. abscondus Wong & Yu sp. n., based on collections in China and Thailand. The other two taxa were originally described as separate species, but subsequently downgraded to sub-species. The morphological differences between the three taxa are similar in extent to those recorded between other Ceratosolen species and we therefore re-instate them as the distinct species, C. solmsi (Mayr) and C. marchali (Mayr). An identification key is provided to distinguish between them and relationships between Ficus species and their Ceratosolen pollinators of this and related species are discussed.
