Is this Bimaculoides or Bimaculatus?

I’m reading contradictory information about how to use the eyespots to distinguish between O. Bimaculoides and O. Bimaculatus. Which one has a a solid ("sunburst-like”) blue ring, and which has a broken (“chain link”) eye spot?

Here’s a picture of the ring on a little Bimac I caught in a tidepool recently. I would call this ring solid, unbroken, and “sunburst-like”, as opposed to “chain link”. So is it a Bimaculatus or a Bimaculoides (or is the blue ring on the eyespot inconclusive)?

This photo is not too clear. Look at the photo in the bimac care sheet - you can see the unbroken "chain links". That's what an O. bimaculoides's ocellus looks like. Most likely the eye spot you photographed looks like this.
