Nhandu Chromatus 4.5"

Male or female? Thanks.
I'm so bad at vental sexing, lol. I have 12 T's and this one I wasn't sure of.

I literally thought this was male, trying to follow the guidelines found here:

In the photo, what tells you it's a female?

Thanks in advance!
They actually give pretty good examples on that page, but it still takes practice to understand what you're looking at. In your specimen here, notice that even though it does have dark setae on the anterior lip of the epigastric furrow, those setae are not concentrated densely in the center and are spread all the way across the lip. That anterior lip also has a pronounced bulge and has a smooth arch from one book lung to the other. In a male, the lip would have a much less pronounced bulge (would be almost flush with the abdomen), would be more of a flat line from one side to the other rather than curved, and the setea would be concentrated in the center, often with a little notch or dimple right in the center of the furrow (these are the epiandrous fusillae, which are specialized setae that males use when making sperm webs).
 
Wow, you do need practice! I'm a newbie, just started collecting in past 2-3 months.

I purchased a 4.5" G. Pulchra from a breeder who told me female, I posted it here, and
the ruling was male.

Contacted the breeder and now I have to wait for that breeder to come to an expo
nearby for me to exchange for the pricey female I paid for. Although I have to say,
the male is quite feisty, likes to play with my tongs/brushes, eats well & never hides.
I might just pay the smaller price to keep him too, I can count on him to roam around.

THANK YOU for taking the time to explain it to me.

Hopefully the breeder made an honest mistake with the pulchra - it sounds like it, since they're willing to make it right.

If you compare the pics of your N. chromatus and the G. pulchra, you can clearly see some of the differences that I was mentioning above. G. pulchra has relatively straight furrow; dark, concentrated patch of setae (epiandrous fusillae) with a notch in the center; no pronounced bulge in the anterior lip - all of which are not present or different in your N. chromatus.
