Figure 3. Pleon-holding mechanism of Parathelphusa pantherina (Schenkel, 1902), ♂, 36 × 28 mm, Indonesia, (ZRC2000.1705), marked on a 3D volume reconstruction of the cuticle, based on µCT images. a-b: Three-quarter view of specimen. Scale bar = 1 cm. (a) Specimen complete, telson and sixth pleon segment in natural position. (b) Telson and sixth pleon segment removed from reconstruction, buttons visible inside sterno-abdominal cavity. (c) Specimen in dorsal view, volume reconstruction of cuticle rendered see-through. Pleon in folded position, buttons in contact with sockets (arrow). Scale bar = 5 mm. (d) Surface reconstruction of sixth pleon segment and telson. Ventral surface with socket in view. B: button; so: socket. Orange: telson; red: buttons; yellow: pleon segment 6. Scale bar = 5 mm.
