P formosa sex

[Marija]

Today my formosa molted and I was able to get the molt out while it's wet.
I don't see a flap or anything that would say female, so my guess is it's a boy?

Looks like it.

I've tried and tried to get accurate at vent sexing, but for me its only sure in adult/obvious male or female spiders. I still have trouble molt sexing most spiders under 3". Practice practice practice..

Well, my formosa is over 3"

Yeah, he's male

Darn I was hoping for a female... Thanks

i agree with @Casey K. That epigastric fold is quite curved and forms a larger angle with the median line.

The internal anatomy is male, though. It's a boy.

What are those two little clear-ish looking flaps? Or am I seeing things? Lol....well, when I'm wrong I'm wrong, lol.

That lip totally threw me off. Fat ass poecie, lol.

OK. The exuvium convinced me--male. Damn--I hate to be wrong. I am eating my liver @Thistles .

I'm not eating mine, lol. **** happens. It is what it is. Besides, you can't be right all the time. Everyone makes mistakes.

Did you see that pic I linked earlier in the thread? It's a guessing game. Sure, you can tell some of the time and it's better than nothing, but there's no sexing like molt sexing!

Agreed!

Yes, but you called it prior to viewing the molt. Color me impressed!!!

It's easy to mess up trying to vent sex, unless you have a whole lot of familiarity with several species. That's what it comes down to. And even then, if its an immature spider, there's a possibility of being wrong. I won't even respond to vent sexing threads anymore, unless I'm sure. I've been wrong too many times about my own spiders...however, as stated above, molt sexing don't lie. Unless the molt is under 3" and you're me..

Thanks Mass. I feel better.
