On the Monophyly of the Spider Suborder Mesothelae (Arachnida: Araneae)

A newly observed character, apparently unique to liphistiid spiders, supports a hypothesis of their monophyly. Flattened spurs situated distally on the prolateral and retrolateral sides of tibiae I-III can contact slightly raised, oval, unsclerotized areas situated proximally on the sides of metatar...

Description
Summary:	A newly observed character, apparently unique to liphistiid spiders, supports a hypothesis of their monophyly. Flattened spurs situated distally on the prolateral and retrolateral sides of tibiae I-III can contact slightly raised, oval, unsclerotized areas situated proximally on the sides of metatarsi I-III. The character is found in juvenile and adult females and in juvenile males, and may function as a proprioceptor of lateral leg deflection.
