Eripha was the name of a mare that belonged to
Marmax, the first of the many suitors of
Hippodamia (notice her 'mare' name, incidentally).
Another mare who belonged to Marmax was Parthenia, and both
poor horses were killed,
together with their master, by Oenomaüs, who was systematically disposing of Hippodamia's suitors as he wanted her for himself. (Strangely, Oenomaüs was said to be fond of horses . . . ) Eripha's name means 'kid', 'young goat' (eriphos), which seems somewhat out of place.
