From ZooTerms (Dictionary of Invertebrate Zoology)
transscutal suture: 1. In many orders, a transverse suture connecting the lateral margins behind the anterior notal wing process, dividing the scutum into an anterior and posterior region.
2. In some Hymenoptera, a suture dividing the posterior part of the scutum into two posterolateral areas called the axillae.
