about what the "protuberences" are. I'm going to have to dig into that question. Problem is, they are way too fat for furculae, and they are under the tip of the supra-anal plate instead of above the base. The "protuberences" are at the point where the pallium meets the supra-anal plate in the illustration. The pallium is basically a covering for the genitalia hidden underneith; it is attached to the subgenital plate. The genitalia can be exposed by pulling gently down on the subgenital plate. In most related species the two lobes or "protuberences" in question are small and not noticeable, and most of the time are hiding under the supra-anal plate, and I think are attached to the top of the segment under the supra-anal plate (perhaps they are related to part of the ovipositor in the female?). I do not know what to call them, but they probably have a name. You can see the tip of them in this photo, but they are much smaller; as well as very prominent furculae. I still have things to learn as well.


Too bad I don't have Bradynotes in New Mexico - it would be handy if I could just go outside and look at some, I've only seen a few alive, many years ago.

By the way this illustration is a good one, and shows the main external parts well.
