hello all, are these pics clear enough to see the "lips"? look like a female to everyone else?

I'm going to say male - because the booklungs look close together and there looks like a dark triangular patch above the epigastric furrow...

Ed,
That first pic. looks female to me. The second one is to dark to see clearly.
When you bring up the pictures on your PC, Can't you lighten them up a little with the program you use? I bet you can.
If you look at the spider from the side , can you see a raised area at the epigastric furrow. It looks like a bump. If you could pick up the T, you could rub your finger over it and feel the bump.
Bump means female, no bump= male...

bump or white lip?

Hi,
I'm wondering if people are attempting to sex their tarantulas by looking for that white/pale lip at the epigastric furrow, and applying that to tarantulas other than Poecilotheria.
This is a fairly accurate way of sexing Poecilotheria, but IME not in other species.

Hi Ed,
I'm with Bill on this one, the epiandrous fusillae stand out well in the first shot. The females just don't have that noticeable dark patch where the fusillae are located. Has to be male.

Cheers,
Steve

LaRiz,
As far as I know, the bump holds true in all female T's.. At least on all of my females.. The lip, as far as my T's go, are pretty much the color of the T's underside. Except the edge may be darker.
Keep in mind I don't have any Poecilothera sp.

Maybe we'll get some other points of view, when everybody gets back from the holidays.. Its been kind of dead around here lately.

For comparison, here's my 4" juv that I sexed as female from a molt a couple of months ago... Looks like there are some differences. (MAN was that spider pissed! I'm itching like mad)

Also something I just noticed - the furrow is noticeably closer to the anterior booklungs on Ed's than mine, which has its furrow closer to the posterior set.

Ernie,
I'm aware of the bump, and the dark spot. I was just wondering about the white split that is sometimes evident in Poecilotheria, and if some people were looking for the white split in other tarantulas.
thanks,
john

Hehe... Look at all the spiderporn! Tarantula bottoms everywhere! ;P Anyway, I think I will apply some of what I'm reading here too and see if it holds true for any of mine. I want to know if my t. blondi is female or male, and all I know is to wait for a molt to find that out.

Hi Ernie,
Are you sure that's a male??? Because I don't see any epiandrous fusillae there and on B.smithi the fusillae stand out bigtime. How did you sex that spider?

Cheers,
Steve

Steve,
After its last molt I sexed the skin. There was just a fine line between the book lungs. No leaf, flaps or folds of any kind.
I hope I'm wrong, but I dont think I am.

Look at the Male or female thread and tell me what you think there.

Thanks Steve,
Ernie
