Emperor Scorpion Gender?

[91Deadravens]

Hello! I've acquired a trio of Emperor Scorpions. At first I thought I had 2 males and 1 female. Now Im not sure.
My guess was
#1. Female
#2 & 3. Males

But under closer inspection I'm thinking I have 3 males. My local pet store had a suspicious number of these scorpions with all the same genitalia so I'm wondering if the shipment they received was tailored that way.

These look all male to me. The operculums are all oval. In blacklighting its kinda hard since its a little fuzzy.

Number 1# is questionable with the v shape cutout in the operculum cause its more pronounced than the others.

It's funny because the blacklight was the only way for me to see the genitalia more clearly.

#1 does indeed appear more female to me but the operculum doesn't quite look the right shape. However as you noticed, the v shaped notch it more pronounced. Also in person the pectines are smaller than the others, not drastically but noticeably, and they are all equal size at roughly 5 inches including tail.

#2 & 3 each have a V notch as well but smaller. I was leaning towards male on them as the operculum is more oval, but that slight notch confuses me.

Are they all the same size?
