I’m thinking that kind of looks male-ish

I'm thinking male too, mainly because of the position of the book lungs relative to the epigastric furrow.

@boina
Why? My confirmed female don't look anything like that. Can I post a picture of her? Just trying to understand why I'm wrong.

@Harry Haller I don't see any epiandrous fusillae and there appears to be a gonoslit so that rules out a male to me, I assume boina's going with the same logic.

This is not a contest. From what I have seen and the conclusion I can make from all of that; the picture shows a male. Sorry, I can't make a case to defend my point in English. I'm happy to be wrong tho.

@Harry Haller Because of the epigastric furrow. A male cannot have an epigastric furrow (gonoslit) with this wide of an opening - it's against their anatomy. Interestingly, individual animals can show some differences in exactly how the area looks, so you need to know which signs to look for and which to disregard.
