Hesiod, Catalogue of Women Fr. 137b-c Most.
b. ... According to Hesiod, Aischylos and some others, Pleisthenes was the son of Atreus and Aerope; and from Pleisthenes and Kleolla, daughter of Dias, were born Agamemnon, Menelaos and Anaxibia. Because Pleisthenes died young, they were brought up by their grandfather Atreus, and so many considered them to be Atreidai. — Tzetz. Exeg. Il. 1.122 (p. 68.19 Hermann)
c. According to Homer, Agamemnon and Menelaus were the sons of Atreus, son of Pelops, and of the Cretan Aerope, daughter of Katreus; but according to Hesiod they were the sons of Pleisthenes, a hermaphrodite or disabled person, who wore women’s clothing. — Schol. in Tzetz. Exeg. Il. 1.122 (p. 11 Papathomopoulos)
I've always seen Pleisthenes as just a characterless placename that was made up to lengthen the line of Tantalos (which is probably still the case); but now I'm more than intrigued.
