Details of thoracopods (continued from Figure 4) and pleopods. A. Anterior part of a specimen of Pseudosculda laevis (Schl├╝ter, 1874) (no. 8) in lateral view. Note the teeth on the large dactylus (2) and the size difference to the posterior three dactyli (3-5) of the thoracopods. B. Dactyli of the thoracopods of a specimen of ?Sculda pusilla (no. 9). Note the size difference between the large-sized second thoracopod (2), the medium-sized third (3), and the small-sized fourth and fifth ones (4/5). C. Posterior thoracopod, i.e., walking limb of a specimen of Sculda sp. (no. 1). D. Pleopods of a specimen of Sculda sp. (no. 1) in lateral view. No details apparent. E. UV-composite-fluorescence image of a specimen of ?Sculda pennata/spinosa (no. 4), details of the pleopods in ventral view. F. UV-composite-fluorescence image of a specimen of Sculda sp. (no. 10), detail of the single preserved pleopodal exopod in dorsal view. Note the smaller number of setae compared to E. G. Red-cyan stereo image of a specimen of ?Sculda pennata/spinosa (no. 11), detail of a right pleopod in ventral view. Note how the paddle-shaped endopod is smoothly bent.
