Hadrurus arizonensis sexing (request)

Hi,

can anyone help me to sex a friends Hadrurus arizonensis with this pic of the pectines? I'm thinking it's a female, she thinks male.

I don't know upside down heart? Isn't that typically male in P. imperator. Mine has the same nic in the pectine I wonder if that is sexual dimorphism.

Definitely female.

My reasoning: >>link<<

Thanks Mike! These pics were really helpfull! I have found something like that on the ATS board but the pics were not quite as good as the ones on AB.

And thanks for moving my thread, I totally did not see that there's a sexing section

No worries. Glad I could help.

Here is an excerpt from a post by Kari McWest:

"...Female... Look at the pectines where they join the body. The "piece" from which they articulate is called the "basal piece". Look at the angle of the pectine from the basal piece to the first tooth, then down the edges of the teeth, you will see that it forms an obtuse angle, roughly 120° and are parallel to each other:"

"Male... Notice the pectinal teeth are larger (both of these are adults, mind you), giving the pectines a more "fluffy" appearance, as some of us say, and the basal edges are acute, roughly 90° and often overlap, depending on the species, sometimes even extending beyond the legs and visible from above:"

Link To Post... No longer exists

So I too would agree... Female ♀

Third opinion:...male...JK female for sure.

Thanks for your opinions and for your help!
But the link Thaedion posted doesn't work any longer. It says that the forum doesn't exist.

That was a link to the old scorpoforum, then it turned into a reptile forum... now I guess the owner took it down completely...

Yeah he did LOL.

I have found the pics Kari used to explain the angle of the pectines on the ATS board. Combine the pics with the text Thaedion posted and you have the now deleted post by Kari
