Necremnus (parasitoids) Thomson, 1878
This genus of wasps is widely distributed and includes around 30 species of ectoparasitoids. The hosts are larvae of lepidopterous leafminers, larvae and prepupae of some Coleoptera, as well as larvae of leaf-mining sawflies (Tenthredinidae). Several species are of interest as natural enemies of pest species. For example, Necremnus tutae, is an ectoparasitoid of the invasive South American tomato moth, Tuta absoluta. The wasp is native to central and western parts of the Mediterranean region.
The genus Necremnus is characterised by a combination of morphological characters, like the structure of the antennae, which has a 3-segmented funicle, as well as a 3-segmented club. In males, the antennae have 3 branches.
