Pseneo

Pseneo is a genus of cuckoo wasps (Chrysididae) belonging to the subfamily Amiseginae. These wasps are generally small and metallic in appearance, exhibiting a range of colors depending on the species. Pseneo wasps are kleptoparasites, meaning they lay their eggs in the nests of other wasps or bees. The larvae of Pseneo then consume the host's provisions.

Pseneo wasps can be distinguished from other Chrysididae by a combination of morphological characteristics, including specific features of the antennae, thorax, and abdomen. Their host preferences vary, with some species specializing on particular host genera or species.

The distribution of Pseneo wasps is global, though certain species are confined to specific regions. Further research is ongoing to fully understand the taxonomic relationships within the genus and the ecological roles they play in their respective environments.
