FIGURE 1A–D, Mixibius parvus sp. nov. (Holotype). A, Detail of the cuticular ornamentation. B, Bucco-pharyngeal apparatus. Pharyngeal apophyses (arrow) and placoids are in focus. C, The hook-shaped dorsal apophysis for the insertion of the stylet muscles is clearly visible. Arrows indicate the cuticular thickenings of the buccal tube wall following the hookshaped apophyses for the insertion of the stylet muscles. D, The hook-shaped ventral apophysis for the insertion of the stylet muscles is clearly visible. Arrows indicate the cuticular thickenings of the buccal tube wall following the hook-shaped apophyses for the insertion of the stylet muscles. (The photos B, C and D are of the same specimen in different orientations as this newly mounted animal was moved to provide the appropriate images.) (Scale bar = 10 µm).
