A. geniculata, I think roughly 3" Any guesses?
Thats a lady
I'm glad to hear that. I was guessing that was the case. From my understanding the males are supposed to have a dark spot between the anterior book lungs at some point in development, and was guessing based off of the lack of that. I know there's something about the shape of the epigastric furrow that's more important, but I admittedly don't know what I'm looking for on that front.

Some species lack the obvious epiandrous fusillae (the black 'dot'(i always saw it as a triangle?))
But what gave it away was a nice spread between the book lungs and the white "lips" under the furrow

I see. That's good to know. When you talk about the spread between the book lungs, are you talking about the spacing between the anterior and posterior pairs, or the spacing between the left and right lungs in a given pair?

The spread between the two anterior book lungs. This obviously isn't a set-in-stone clue, but in some species, the males have it narrow and straight.
