title: Table 2 in A comparative description of the mesosomal musculature in Sphecidae and Ampulicidae (Hymenoptera, Apoidea) using 3 D techniques

description: Table 2. Terminology of the thoracic and abdominal musculature of all specimens examined. Origination and insertion are described on the basis of Sceliphron. If a muscle is absent in Sceliphron, the description refers to Sphex or Ampulex, respectively, if absent in Sphex. The list is sorted caudad (from thorax towards abdomen) by insertions of the muscles and by assumed functional groups. X = muscle present; - = muscle absent;? = uncertain homology. A homologisation with the generalised nomenclature for neopteran thoracic muscles of Friedrich and Beutel (2008) is presented.
