From Kristensen 1987: “Echiniscidae with flexible buccal tube, pharyngeal bulb with a drop- shaped structure located on the placoids. Eyes possibly black, but nearly disappeared during the preparation. All four segmental plates I-IV unpaired with two bar-shaped median plates 1 and a distinct bar-shaped median plate 2; primary and secondary clavae with ring shaped annulus […]
