With the 'e.gilberti' females on the bottom pics, they were collected in the same area (and sometimes the same swoop) as E.gilberti males. There were several more males in the area than females, but both were fairly abundant, and there were no other obvious evergladei ever collected in this area that I recall. I do recall collecting e.zonatum further up stream in this area and in the next stream over.
I have also noticed that upon adding one of the females (picked a plump one with the amber ovaries to be sure) to an established tank with a male in it that within short order of finding her he would darken out and start doing his wiggle waggle. Could've been a one-off, though, so i'll try again a few times and record the findings.
At the time of these pics I had already taken out the obvious males (i.e. black/blue finnage). I've still got them in the picture so I'll take a look again tomorrow and see if they have changed at all. If not then I'll just put them back into the tanks and update.
Is it possible that it's just a locality variant? What about a natural hybrid?
A few key trait differences to look for would help. I've yet to see scales on the head of any of these fish, including the known e.evergladei, not sure how you'd go about that without damaging the fish. Based on the area the only possibilities are e.zonatum, e.evergladei, and e.gilberti.
