Figure 3 in High level of phenotypic homoplasy amongst eutardigrades (Tardigrada) based on morphological and total evidence phylogenetic analyses

Figure 3. The four states coded in the present study for the shape of the apophyses for the insertion of the stylet muscles (AISM) (characters 14, 15; Table 2). A State 1: AISM divided in two; B AISM shaped as one ridge; C AISM shaped as two ridges; D AISM shaped as three ridges. The images represent half a buccal tube in lateral view. The arrow in B indicates an apophysis for the insertion of the stylet muscles connecting with the end of the mouth. The rest of the apophyses for the insertion of the stylet muscles connect with the beginning of the buccal tube.
