The Paracentrobiini represents a putative monophyletic group based on Molecular (28S D2 and D3 rDNA) and morphological characters within the Trichogrammatidae with a worldwide distribution. The Paracentrobiini are known to commonly parasitize eggs of Heteroptera (e.g. Miridae) and Auchenorrhyncha (e.g. Cicadellidae). These hosts are important crop-damaging taxa. The subfamily appears also to be a large component of the Trichogrammatidae fauna in many temperate natural habitats especially desert and Mediterranean environments. A large specious fauna exists which has been unaccounted for taxonomically. Currently applied sciences have been unable to take advantage of this group due to the taxonomic impediment which clouds species level identification within the group. A hypothesis concerning generic relationships within the tribe is presented and issues in species level taxonomy are addressed.
