Stomotheca
（重定向自Epistome）
Stomotheca is the term applied to the feeding apparatus in front of the mouth of harvestmen, and sometimes the related scorpions. Usually it consists of the epistome (labrum), two pairs of coxapophyses (endites, maxillary lobes) and often a labium.
The epistome is a projection that forms the anterior wall of the stomotheca. Its upper side is hardened and divided by a transverse invagination (sulcus). The part nearer the groove is sometimes called clypeus, the other one labrum. The area around the mouth is soft and flexible, often with a distal lobe. On the sides, the walls around the mouth are fused to the medial surfaces of the pedipalpal coxae, and a transverse muscle attaches to the inner surfaces of the epistomal walls.
