For this topic you SHOULD read the latest commentary of Lysistrata, which this year was J. Henderson’s Oxford 1987. (This is not the OCT, and definitely not the Loeb which doesn’t even have an apparatus criticus, it’s a full commentary.) One who usually hits the mark ascribing lines is J. van Leeuwen’s 1903 edition. At the end it’s not a huge problem. I don’t remember the details, but it probably makes no difference whether it’s Calonice or Myrrhine saying those lines. Myrrhine has a larger role later on in the play vis-a-vis Cinesias. Then it is clear it’s her.
