I have noticed this with the 8 rufilata specimens I have as well, even though you noted metallica only.Sexing metallicas is relatively easy, it has nothing to do with book lung placement or even epiandrous fusillae.
It's much easier to tell when they are slightly larger but you can consistently sex (metallica only) them by looking at the epigastric furrow...in females it's usually a straight slit accross, males will have a little "notch" "arrow" or "triangle" in the center of the furrow.
They are (in my opinion) pretty easy to sex ventrally. I'm still having a hard time dorsally sexing the damn things though.
