You can't really see it in the pictures but it kind of has a little V shape like a male would have, but I don't see any black dots. That's what was making me unsure!
Usually with a female you will still see the V-shape, just not as easily often times. Also, the males will have a bulge at the base of their tail on the underside, where their sex organs are stored. Females will not have the bulges.
