Crenubiotus crenulatus s.s. (Richters, 1904) from Spitsbergen: claws. (a) Claws I (PCM). (b) Lunula II (PCM) (c) The cuticular swelling/thickening under lunula II (PCM). (d) Claws IV (PCM). (e) Lunula IV (PCM). (f) The cuticular swelling/thickening under lunula IV (PCM). (g) Claws I (SEM). (h) Claws IV (SEM). Photos (b,c) and e–f show the same lunula, respectively. Empty flat arrowheads indicate slight constrictions in the middle of the claws, the filled indented arrowhead indicates double muscle attachments below the claws, filled flat arrowheads indicate cuticular swellings/thickenings under lunulae.
