Family: Eohypsibiidae Bertolani & Kristensen, 1987

Synonym: Amphibolidae Bertolani, 1981

Emended diagnosis. Claw structure (used to identify the family) is divided into three parts: base, secondary branch and main branch, which are clearly distinguished, sequentially inserted, and separated by septa. Claws of the same leg may be of similar size, but always exhibit different angles between the main and secondary branch. An acute angle (about 45°) is formed by the external claw, and an almost right angle (80°) by the internal claw, which can rotate on its base by 180°. When the claws are of different size the external or posterior claws are larger – especially on the fourth pairs of legs.
