Abstract
The African catfish Platyclarias machadoi stands out from other clariid species by its extremely dorsoventrally flattened skull. This paper focuses on the spatial constraints and consequent functional interdependencies in this very low skull (average skull height of 27.5 +/- 3.0% skull length); such as the medial position of the retroarticular process on the lower jaw, the horizontal position of the suspensorium, the lateral tilting of the pterygoid bones and the anterior part of the quadrate with regard to the suspensorial transverse long axis. These characteristics can be presumed to have major influences on the capacity of suspensorial adduction, influencing the feeding and respiratory mechanisms. A comparison with other clariid species showed that one of the apomorphies is the presence of an extra muscle (musculus adductor mandibulae A(3)" pars levator tendinis) in the adductor mandibulae complex. This extra muscle lifts the tendon complex of the adductor mandibulae, resulting in a higher moment on the lower jaw. Some comments on the original species/genus descriptions are given.
