Diagnosis: Males of P. ephialtes are characterized by the long posterior prong on the proximal part of the tegulum, and the small triangular RTA with a basal outgrowth with two short sharp tips in dorsal view. Females are recognized by the two oblong, slightly procurved structures near the posterior margin of the epigyne, each with five longitudinal stripes.

Etymology: The species name is a noun in apposition; Ephialtes is a giant from Greek mythology, son of Iphimedia and Poseidon, who wanted to storm Mount Olympos together with his brother Otus.
