I couldn't see the gonopods, so I'm mostly guessing based off of the presence or absence of a spinning organ and/or an extra genital sternite.I agree with your guesses, although I say that very tentatively. 3rd pic looks like there's a prominent spinning organ dead center and the genital sternite seems much more blunt. Could you see gonopods when you were taking pics? Maybe they're just really small on hardwickei?
