Psalmopoeus Cambridgei query

[AndrewClayton]

So I've just noticed this when looking back at old photos. This is a female P Cambridgei

And this image here is a male P Cambridgei

Now is it just me or do the chevron markings on the females abdomen look more prominent? Both T's are the same size (3 inches) sorry if this is already an established way to sex these but I haven't been able to find much info on these being sexually Dimorphic at this size.

Interested to see if anyone knows! I just got a P Cambridgei and they look right in between the two patterns in prominence, about 3 inches as well. I would be thrilled if I had a girl.

Here is a ventral photo of my male for you to compare. You're looking at the spacing between the book lungs and between the top set of book lungs at the epigastric furrow.

I haven't been able to get a good photo on my phone, and when I check my other Ts it's always with a molt. I haven't had this little one long enough to get a molt, but here are the photos I was able to get, just in case someone has a better eye than me. It's pretty hard to tell with the flash, but I didn't try to get any more pictures at the time cause I felt bad flashing them a bunch of times.

Yeah that's a female you have there, the ventral photo isn't that clear but you can tell enough in it. If you look at the male photo I posted there is an obvious black semi circle with what looks like a little hole on the horizontal line. That's male, a female won't have that darkened semi circle and will almost look like a set of lips between the top book lungs, just like you're photo. This is true for the majority of Tarantulas but is a lot harder to tell in some species.

My point in this post was about the chevrons on there abdomen, looking at you're female they are more prominent than the male I have and both look to be around as fat as eachother. My female photo is of her just after a moult so she's skinny and I thought that might have been the case, but when looking at yours it is definitely more prominent.

Anyone else got a sexed P Cambridgei that they can post pics of the chevrons on the abdomen?
