FIGURE 4. Cuticular structures and artifacts. A. Scars on the surface of G. aquaticus from Germany (SR 952). B. The mixture of smooth and otherwise structured surface may be due to erostion (undetermined Gordius specimen from Italy; SR 1367). C. Cuticular surface structure in an undetermined Gordius specimen from Germany; SR 1031). D. Smooth and rough structure of the cuticle in G. z w i c k i sp. nov. (holotype ZMH V13275). E. Cross section of the cuticle (cut) with layers of fibres. Below cuticle are epidermis (epi), longitudinal musculature (mus) and parenchyme (par) (G. helveticus sp. nov., paratype ZMH V13277). F. "Rhomboidal pattern" on the cuticle created by the underlying arrangement of cuticular fibres (G. aquaticus from Germany, SR 995).
