| The maxillae are well developed, the hindwing has a frenulum, and its sub-costal nervure touches the radial near the base. |
| A second branch of the hemipteroid lineage includes insects in which the haustellate mouthparts contain feeding stylets derived from both the mandibles and maxillae. |
| The Notodontidae are stout, hairy moths with maxillae and frenulum developed. |
| There are five large teeth on the maxillae, rather short canines, and at least twenty small and uniform post-canines. |
| The basicranial articulation was no longer the anchor for the palate, and the palatoquadrate was functionally replaced by its dermal anlagen, the maxillae. |
| In the woodlouse these excretory organs open on the second pair of maxillae. |
