Yeah they are. Good examples too

Good to hear. I'm not sure if it's legal to post pictures of all 11 pages of them.

I do the same thing - check everywhere on the internet before posting and asking for feedback. And, while I often don't have a problem finding mature female spermathecae, there is a real shortage of immature female examples. Many people are checking for sex far before they are mature and there are very few resources.
That is why I have been making an effort to post my immature females in the gallery when I can. A lot of those photos are around the 3" mark, or less when possible, and that is when a lot of people start searching for examples that they can compare to.

Heteroscodra maculata


Hope this is clear enough, it's the best one I have.

Immature (prob around 5.5" relaxed legspan) Pamphobeteus sp. "Santo Domingo Goliath" -- my guess is it will be fully developed within the next 3 molts.

Haplocosmia himalayana

I need to stop throwing my molts away. :/

Delete this is you want, but I thought it was pretty neat, and has helped a lot of members out in the past.
How to ventrally determine male from female in Thrigmopoeus psychedelicus (Male left / female right)

 

[KezyGLA]

How big was the male on the left ?@Austin S.

How big was the male on the left ?@Austin S.

Both were 2.5-2.75" leg span.

Both were 2.5-2.75" leg span.

Thanks mate. Just wondering when that fussilae spot starts to show. Its pretty obvious. Thanks for sharing man

He's a boy, right? I can't find a flap/pocket between the upper book lungs, but this is the first time I've really tried to sex a molt.

 

[Bumba]

I think perhaps the best way to help people learn to sex would be just to show photos of each gender. I will get the ball rolling. This is a female B. smithi.
molt:

Note the flap on the molt. Its the give-away for females. Absense of some sort of flap indicates a male, but remember to look closely! Some are tricky.
ventrally:

1. Males, especially more mature males may have a patch of somewhat thick hairs here.
2. More of a lip (this is where males deposit sperm). Males sometimes appear to have a "hole".
3. In comparison, females have a farther distance between the second book lungs.
4. Males sometimes appear to have a "half circle" patch. It is absent here. Sorry, its asymetrical.
The other two things have no significance, i just couldnt help myself :8o

Thanks. That helps.

I've never tried holding my T's this way, do you find it to be effective?

Do not hold an old world like this. That guy has guts.

Does anyone have any pics of male and female moots from Pink Salmon Bird Eater? I want to know what I am looking for. Also, I was told by Tarantula Canada that I would be able to determine sex until sling is at least 1.5 inches? Accurate?

well I was going take pic of the molt of mi lasi fir you. But her was so shriveled even with water I tore it. No it's not accurate. You just need a microscope or a good camera to get close up in between the book lung.
