Take a look at the ones I circled. Most do look like wide horns, but a few look very flat and darker. I got them as smaller nymphs from someone on the site as wide horns and they also sold me a group of Flat Horns, so I wonder if either some got mixed in, or they are actual hybrids. Unfortunately these guys don't look exactly like the Flat Horns I got, those do look more pure linage. Here are some more close ups of what are supposed to be G. oblongonota zoomed in...
