Mesosoma

The term refers to Mesosoma at waist wasps ( Apocrita ), so the Hymenoptera wasp waist, the fusion of the entire thorax with the first segment of the abdomen ( tummy).

The sternum of the first abdominal segment is reduced in this case, and is referred to as propodeum or Epinotum. It is firmly adherent to the metanotum. At the mesosoma, the "rest" of the abdomen connects to, which is referred to as metasoma.

Even with stick insects ( Phasmida ) and earwigs ( Dermaptera ) and in a subset of pine lice ( Mallophaga ), there is a more or less strong fusion of the metathorax to the first abdominal segment.
