Eunotus Explained

Eunotus is a genus of chalcid wasps. Most species are parasitoids of scale insects.^[1]

Description

The antennae are inserted above the clypeal margin, and they consist of either four or five funicular segments. The thorax has a dense reticulate sculpture, with the frenal line on the scutellum usually being absent. The scutellum does not extend beyond the propodeum, and the propodeum has a distinct tooth-like median carina. The fore-wing is covered in fine hairs. The first gastral tergite covers most of the gaster.^[2]
