Amphion and Zethus
In the "Bibliotheca", the Arcadian genealogies are immediately followed by the Atlantids, and this progression is known to mirror the structure of the "Catalogue" because other fragments of the papyrus roll that transmits the Telephus myth cover families of Atlas' daughters: Taygete, Electra, Alcyone, Sterope, Celaeno, Maia and Merope. Maia bore Hermes to Zeus on Mount Cyllene. Taygete also slept with Zeus, becoming the mother of Lacedaemon, through whom much of the Spartan line was traced, including Tyndareos, the father of Helen, and Penelope, the wife of Odysseus. To Zeus yet again Electra bore Dardanus, the progenitor of the Trojan line, and Eetion, who was killed for sleeping with Demeter. Dardanus' sons were Erichthonius and Ilus. Hyrieus and Hyperes were Poseidon's children by Alcyone. Her section included the Ehoie of Hyrieus' daughter Antiope, who bore Amphion and Zethus to Zeus. Hyperes' daughter Arethusa slept with Poseidon and was changed to a spring in Euboea, but not before bearing Abas, the eponym of the Abantes. His line is traced down to Elephenor, leader of the Abantes in the Trojan War. Sterope lay with Ares and bore Oenomaus, but it is possible that this union was delayed to book four as part of the section treating the family of Pelops and Oenomaus' daughter Hippodameia.
