The "shape" of the line running from the head to tail, head shape and spangled tail and lugubris type body plus the stripes make me 100% certain its a cinctaHard to tell. Where'd you get them and price range? I can see why you'd think cincta given their vertical striping pattern under the dorsal but doesn't seem like it to me. I'm at a loss.
So hard to tell when small. it will be easier when they hit 7 inches or so.
Dimorphic.Are cinctas dimorphic or monomorphic?
