Female?

[Draiman]

Haplopelma albostriatum, 3". I am quite certain it's a she, but I would like some confirmation, especially since her abdomen is so black I can't tell if there is a patch of thick dark hairs above the furrow, which would indicate male. Sorry about the quality - it was taken through the old, scratched plastic of a KK.

Thanks in advance.

I'll be curious what others have to say about this one. I don't know how you could tell behind all that fur.

Looks female in the pic. I have the same problem with the dark ones.

I'd say wait for a molt to confirm, but I don't think I've ever gotten one of my haplopelma's molts... They seem to push them into the wall of the burrow and web over them.

Here's a better picture of the same spider.

Female, right?

In the brighter pic there appears to be a patch of dark hair, I would guess male because it also has that "pinched" appearance that I read about, but I'm kinda new to the sexing thing. I don't trust myself to sex my own t's because wishful thinking tends to get in the way lol.

I still think it looks female.

I would say female based on what I am seeing.

You don't sound very confident.

Much better pic. I don't see any dark patches or hairless spot so I'd say female as well

 

[Draiman]

What about this one? It's also H. albostriatum, 3", but a different specimen.

 

[Draiman]

Anyone?

The first specimen I say female as well. This latest one I would say male.

I am pretty sure both of those spiders are female.

Thanks , but based on what?

I am rather leaning towards male for the second one.

the dark patch on males is usually not that wide. there is a darkened area, but notice how wide it is on that second specimen.

but it can vary from specimen to specimen, so i could very well be wrong, but like i said, i'm pretty sure both are female.
if that does turn out to be a male, that sure is a wide dark patch!

True. Then again, I do not see a prominent "slit", nor do I see the white hairs that are very obvious on the first specimen. :?

that goes back to what i was saying about every specimen is different from one another. if that 2nd pic is a male, then that's an awfully large dark patch lol

The "slit" method of sexing is just absolutely terrible. The epigastric furrow exists on both male and female spiders. We, as humans, assume a slit in a genital region means female because that's how we are.
