) revealed the three-dimensional morphology and the arrangement of the cephalic appendages and also confirmed the presence of terminal pores on the cephalic cirri and the primary clavae. The conical shape of the secondary clavae seems not as evident as in light microscopy probably due to the overlying outer epicuticle. The large anus is not on the ventral surface and rather direct posteriorly (Fig.

Regarding claw/digit morphology, the peduncles (internal structures) were not recognised but the three hooks of the internal claws and the single-pointed external claws were recognised (Fig.
