Mesosoma

In waist wasps ( Apocrita , the hymenoptera with wasp waist), the term mesosoma describes the fusion of the entire thorax with the first segment of the abdomen .

The sternum of the first abdominal segment is reduced in this case and is called the propodeum or epinotum. It is firmly fused with the metanotum . The "remainder" of the abdomen, called the metasoma , adjoins the mesosoma .

Also in Gespenstschrecken (Phasmida) and earwigs (Dermaptera), and at a part of the jaw lice (Mallophaga), there is a more or less strong fusion of metathorax with the first abdominal segment.
