{Double claws similar in shape and arranged asymmetrically with respect to the
median plane of the leg (conventionally described as sequence 2121); claws may be
of similar size; double claws of Eohypsibiidae type (¼Bertolanius type): subdivided
into three distinct sections, basal section, secondary branch and primary branch
(rigidly joined to the secondary branch), one on top of the other and separated by
septa; the angles between the main and secondary branch different in external and
internal claws—an acute angle (about 45) is formed by the external claw, and an
almost right angle (about 80) by the internal claw; internal claws can rotate on their
base up to 180; lunules present. Buccal tube completely rigid or caudally annulated;
ventral lamina absent; 14 peribuccal lamellae present; pharyngeal apophyses and
placoids present. Eggs laid freely (or in the old exuvium) and surrounded by an
