The place name is not mentioned in the source.
If the Olympia inscription did not mention any Nemean victories, then the two Nemean victories, if Aristodamos achieved them in the same discipline, may date to 387-385 BC. If Pausanias, or a copyist, made a slip, and the Nemean victories date before 388, then they may date to 391-389 BC. Overall, we cannot to better than to suggest that the Nemean victories fall between 391 and 385 BC. -EK
