Poecilotheria: ventral sexing vs. dorsal sexing

[ZergFront]

Perhaps a little off topic, but Joe, you have a 8" P. formosa?

I thought they were one of the smaller Poecilotheria species.

Check out his new T.bondi video. It's gigantic! :liar:;P

This will be helpful once my Pokies will actually let me see under them. I'll have a little more advantage once they outgrow the deli cups.

I'm thinking male on this one, right?

Thread resurrection!

I was curious what some of the members who prefer dorsal sexing think of these two P. subfusca:

I'm obviously very new to the hobby, but I have read quite a bit about dorsal sexing of pokies and I would say male.

Toni, there are two different specimens pictured.

I know. I say male.. for both. According to everything I have read, the inner patterning on the abdomen is usually is much darker than the outer patterning for males. And of all the comparison pictures I have seen, the females inner pattern is much lighter - very close to the same color as the "border" of the pattern on the abdomen. That's why I am guessing male for both. I could be wrong, but that is the information I have gathered in the weeks I have been researching this. I'm fascinated with pokies, although it will be a very long time before I have one. If anything, the first would be female because it is slightly lighter, but I think male.

OK, well after skimming through the gallery of pokies and comparing P. subfusca I have to admit that with this particular pokie - the female isn't as light as the rest of them so it's very possible that the first pic is a female.

Skullptor - what species is that, and how big?

BCScorp - thanks for the link; I just now got to reading it. Great thread.

I never did post pics of the P. formosa...I'll have to dig through and see if I can find them. I was definitely wrong when I said she was 8", that's for sure.

MichReptiles - Thanks for your guesses, and for your explanation. Gives me a little more to think about. I need to get some ventrals of the larger (pictured first) subfusca. I haven't had a good luck since it was about 1-1.5".

Gotta dig em' out.

Typically that white furrow indicates female. I have never seen a male with one that obvious.

yes, that would be correct
formosa, right?

 

[xhexdx]

P. subfusca - any guesses at gender?

FYI - this is the ventral of this specimen:

Here are two more dorsal shots:

Female fo' sho'

Female fo' sho'

I agree, but would you say female based on both ventral and dorsal shots, or would you pick one over the other as being more obvious?

For me, the ventral shot is much more obvious.

Btw, grats on your sac.

I'd pick the ventral shot as being the most obvious. These guys are easy to sex, even at 4i.

Btw, grats on your sac.

Thanks!

Joe, the dorsal sexing I think is for older specimens, because the folio fades or stays dark depending on sex as they age. So for small specimens I would think that ventral is better.

Good point, thanks. I had actually forgotten about that.

Just wanted to update this part, since we're discussing pokie sexing in another thread:

This formosa is 2". Male, right?

I have a subfusca that's ~1" exhibiting the same 'dot'. To me this is obviously male, as my female pokies that are larger than this don't have the dot.

I should also add I have a female regalis that's about 3" without the dot, too. I got her much smaller and never saw one.

The formosa and subfusca both 'hooked' out (more like 'bulbed' out ), and the regalis was indeed female.

This is my confirmed female p.formosa 4/5 inch
