The subgaleal area is alsoconnected with the mentum along its interno-lateral margin. Thestipites (St) are distally not subdivided into a palpifer, and are fusedinternolaterally with the subgalea. A single bristle (b) occurs near the externo-lateral margin. It wascalled the setole laterale dello stipite by Russo. In the present paperthe name is modified into seta stipitis maxillaris.
