Figure 2. The Ramazzottius baumanni species complex—morphological variability in dorsal cuticular sculpturing between the three species delineated in the present study, as seen in PCM (all photographs, except for inserts, obtained from stacking multiple images taken in the Z-axis). The less column shows entire specimens, whereas the right one shows magnified caudodorsal parts of the cuticle (photos in columns taken under the same magnification). A, B, Ramazzottius cf. baumanni (slide AR.190.04), the insert shows a magnified cuticle fragment with dark borders between the bases of adjacent granules (the flat arrowhead) and ragged edges of the sclerotized apices of the granules (the indented arrowhead); C, D, Ramazzottius aff. baumanni sp. can. (slide AR.323.01), the flat arrowhead indicates a pseudoplate-like structures formed by dorsal pigmentation, the insert shows a magnified cuticle fragment with strongly sclerotized process apices; E, F, Ramazzottius cf. saltensis (slide AR.467.01), the insert shows a magnified cuticle fragment with weakly sclerotized process apices (the flat arrowhead). All specimens are paragenophores. Scale bars in μm.
