In most spiders the superior tarsal claws have a line of teeth
on their medial ventral line (Fig. 8A–C). In all zodariids (Fig. 8I–O)
except Cyrioctea (Fig. 8H) the line of teeth is placed on the internal
side of the claws, and that was one of the main lines of evidence
for the basal placement of Cyrioctea in Zodariidae (Platnick,
1986; Jocqué, 1991).
