Dot-tailed Whiteface
This is a female, not only no claspers, but for this species the males only have a yellow spot at the end - segment 7 - not all the way down the abdomen.

teneral males
...have spots all the way down the abdomen, as shown
here
but all the spots (except the most distal one) disappear within a few days following emergence, according to Paul Pratt.
This male
is in the process of losing his spots.

Good to know about the spots disappearing. The photo you reference shows it nicely. Thanks

claspers
We would think the claspers would be evident in this image if the animal were male even though it is an immature. Males have long appendages at the tip of their abdomen which they use to hold the female behind the head. Yours does not. We would say your image is of a female.

Thanks, John; I see the difference now, after looking again at the chaparraltree photo I linked to.
