My petshop has a "striped Knee tarantula".

[theconmacieist]

Both just G. rosea. If there are hooks then it is a MM (explains the climbing). You should be excited because now if the new one is a female you can do your first breeding!

 

[Amoeba]

Yup your she is a he. Congrats now make some pretty rosie babies

 

[Vilurum]

Ok I am really confuesed now when I was asked to check the pedipalps and legs you ment the DCF G. rosea yeah?

Can we use DCF and NCF (Normal) from now on in this thread when talking about them (I am sure I can't be the only one who is very confused lol)

No Hobo mean't the NCF

 

[Vilurum]

Ok so I had a real good look and tbh I am not sure it was to hard to see but I could find them on ever other sets of legs except the front so I am going to say she? doesn't have them

Also she eats all the time once a week and her abdomen is like that.

Wait does that mean my NCF is a female and that my DCF is a male (Due to the hooks on the legs?) But the DCF is like a tank compared to my NCF I thought the females were bigger, unless the DCF is much older than the NCF?

Ok.

I asked you to check those to determine wether or not it was a mature male or not, which would explain why your two roseas look very different from each other. Here's a post showing both palps and hooks. If your rosea has these then it is a mature male, and with limited time to live.

They are both roseas. As far as I know, there are three colormorphs for G. rosea:
The "Red/Copper Color Phase/Form"
The "Pink Color Phase/Form"
And "The Grey Color Phase/Form"

Note that these forms may have other names as well!

Your new one appears to be The Grey color form.
Your old one appears to be a Pink color form.

Determining age is a waste of time, there is no way to klnow for sure.
Generally mature males will be leggier, while females will be stockier and built "like a tank". Also note that before the maturing molt for males, they will look nearly identical, so until we can get a decent molt/ventral shot, we cannot sex your new rosie. It could be either a female or immature male.

I told you guys Descriptions are not an accurate way of ID'ing. And at FLAmoeba, you can't sex a spider based on abdomen size.

That is 100% G. rosea. It also looks like a mature male as Hobo also pointed out. And there is no reason for you to add DCF or whatever. That is G. rosea. Just a plain old rosie.

 

[Vilurum]

Ah that makes it alot clear, thank you very much.

I still don't get what you mean about the pedipalps though.
I have taken some pics that I will upload now but they are probs bad pics.

Also if my DCF has the hooks does that mean he is male or is a ventral pic needed?

I'm aware how to sex a tarantula. we were talking about abdomin shape.

Upon the maturing molt the ends of the male's pedipals will change into specialized sex organs that are used to collect and later inject sperm into the female. They are bulbs, and kind of fold back behind the pedipalp, making them appear longer and thicker on the ends.

If it has hooks like the picture in the post I linked earlier, then yes, it is a mature male. I'm not sure which one you mean when you say "DCF" but I thought it was your old rosie (NOT the new one) that had the hooks?

These are all pics of the NCF (i'll call it PCF now)
I am sorry if these are of no help but I don't see a better way unless anyone has any ideas.

---------- Post added at 01:04 PM ---------- Previous post was at 01:00 PM ----------

No I am sure my PCF (Pink Colour form) old rosie doesn't have the hooks I have.

The DCF(Dark/Gray colour form) Does have the hooks although they are smaller than the others hooks on the other legs.

 

[Hobo]

Huh?
Alright, I think you might be confused as to what I mean by "Hooks".
Mature male rosea will only have two hooks, located under their two front legs, right after the second segment (counting from the "toes" up.)

Here, look at this video.
[YOUTUBE]L9C91PWkaEw[/YOUTUBE]
He focuses on one of the hooks at 0:06, but you can see them throughout as he waves his two front legs around.
Also note it's enlarged pedipalps.

Your old tarantula to me, appears to be a mature male, as I can kind of make out the enlarged palps in those blurry photos you took. Not too sure though. The easiest way would just be to eyeball it now that you know what I mean!

The new one is definitely NOT a mature male, and will not have hooks. One of it's pedipalps is visible in your ealier photos, and it does not have the telltale bulbs on the ends. It is either a female or immature male.

Oh, by the way, when you take photos, are you using a point and shoot? Even the most basic ones have a "macro" fundtion, usually denoted with a flower icon. If it does have it, use it! It's really helpful for taking close up shots so you can see detail, and will help with the blurriness.

Ok while I did misunderstand what was ment my hooks (I thought it was the black barbs on tips of the feet don't laugh lol) but the pics were of the pedipalps and my attmep at a ventral shot for sexing.

Ok I will watch the vid now and be back in abou 10 or so min I want to give it a really good watch.

Also looking at the 2 of them now on the DCF the pedipalps are the same size all the way down but on the PCF it looks like at the tips they look abit fatter and rounded, hope this helps.

Ok so you guys are sure my G. rosea DCF is a female?

Ok so from watching the vid my PCF has the hooks and and the pedipalps are slightly more rounded and fatter ta the ends.

Does this mean its a male?

If it has hooks it is a male.

Final verdict:

You have two G. rosea

The new one is a "grey color form" and is definitely NOT a mature male. It is either an immature male or a female. Pending a clear photo of the underside or of a specific area of the molt, there is no way to be sure.

The old one is a Pink Color form, and is a mature male, since it posseses both hooks and bulbs. you should see about finding him a girl, as mature males have limited time.

Good luck with 'em!

 

[Vilurum]

Ok thank you very much for all of your help.

Ok I will be able to spam as many pics under the sun tomoz but it is too dark now and my camera battery has died, so I will post pics tmoz and would really like if you could have a look at it.

Also you know mange on dogs? The DCF looks like it has a patch of that on its back, I will post a pic of this tmoz and would love if you could have a look.

thanks.

The small balding patch on the new one you got is from hair kicking.

I'm aware how to sex a tarantula. we were talking about abdomin shape.

I might post the idea that the difference in abdomin shape is due to gender?

If there were a difference in abdomen shape regarding gender, would you not then be able to sex it that way?

 

[Silberrücken]

I'm very surprised, even tho this is an "ID" thread, that no one has mentioned this:

To the OP (Vilurum): in post Nr. 91, referring to your pics.

Please give that rosie more substrate. A search using the "Search" function will provide you with info with how much roseas should have.

To my understanding boys had smaller abdomins and girls had bigger this is why the boys are leggier. by all means correct me if I am wrong.

EDIT: If this holds any truth it is not anywhere as accurate as sexing with the spermathecae
