Topic: Propodeum


  
  Generic Diagnoses - Online Catalog of Ants of North America
In profile, propodeum forms a prominent, rounded convexity that is relatively distinct from the profile of the remainder of the mesosoma.
Propodeum with declivitous face decidedly longer than basal face, both faces meeting at an angle so that the propodeum in profile resembles a distinct upward facing "peak" with a more or less rounded apex (this is characteristic of the genus and is sometimes referred to as the "Lasius peak").
Minors with propodeum usually distinctly lower in elevation than pronotum; mesonotum sloping gradually (interrupted by a notch or depression at metanotal region) to the level of the propodeum or the mesonotum often as high as pronotum and separated from propodeum by a distinct step at metanotal impression.

There is also no trace of the suture between metanotum and propodeum, which is highly unusual in cases where wings are not reduced.
According to Marshall the propodeum is bisected by a carina, forking at three-fourth's of its length and enclosing a smooth triangular space.
The propodeum is not just divided by a carina as in Goniozus: it seems to be completely split by a longitudinal incision, bordered by two shiny rims that give the impression of one single carina (fig.

 Australian Ants Online - Stigmacros Key to Species
The suture between the mesonotum and propodeum is deep and wide so that the propodeum forms a very distinct segment of the thorax.
The propodeum is armed with small spines placed about the middle on each side of the declivity.
The suture between mesonotum and propodeum is very distinct but not deep so that from the side view the dorsum of the dorsum of the propodeum seems so close to the mesonotum that it rises abruptly from it.

Like all representatives of Apocrita, gall wasps have a distinctive body shape, the so-called wasp waist, a term which is also used to describe corsets.
To that end, the first abdominal tergum (the propodeum) is conjoined with the thorax, while the second abdominal segment forms a sort of shaft, the petiolus.
The petiolus connects with the gaster, which is the functional abdomen in apocritan wasps, starting with the third abdominal segment proper.
