Maybe
Just checked BOLD and what literature I could find. The stuff about the orbicular and reniform are not conclusive and I'm not even sure where it came from. Seems like lots of overlap with
A. americana
. Size would indicate that
americana
is more likely, ws=28-36 mm vs 28-31 mm for
interoceanica
. At 2 cm, yours would have a ws closer to 36 mm. But maybe yours is smaller and who knows what the actual size range is for
interoceanica
.
Although this looks more like what some describe as
interoceanica
, the original description suggests that species tends to be darker than
americana
and has a round orbicular. I don't think this should be moved to
americana
but if it were moved to genus, it seems we should move everything in both species to genus.

Thanks, Steve!
Good points. I'll move both local specimens back to the genus-level.
