Psalmopoeus irminia 3inch [2/2]

Posted one earlier, couldn't edit it so I have to make a new image. New to sexing, but based on research I've found similarities to both male and female. I appreciate any help!

      I've done a bunch of research and trying to learn what to look for. It has similarities to both male and female from what I've seen from this article:http://milehighbugclub.com/Methods for Sexing Tarantulas.htm

      But no noticible slit which makes me lean to male. It's also pretty leggy and has a smaller abdomen. I have 4 more though so if this turns out to be a male, hopefully 1 of the other 3 turn out to be female. This is probably my favorite species besides M. balfouri

      I am also practicing my ventral sexing and most of the time, I have no idea what I am looking for. I am gaining confidence as I practice. I would say suspect female on yours, but please don’t trust me. I am new at vent sexing too, but I find practice is the key to achievement.

      @Drea hahaha so am I!! I'm going through all the posts and simply guessing without commenting because I don't think my comment holds any weight. I think this one is still too young to really tell. It's 3 inches FULLY extended. But from carapace to abdomen it is maybe an inch. Possibly shorter. I tend to look at the shape of the arch that connects the book lungs. If it's straight, that's a male, and if it makes a U shape then it's a female. Although not 100%. I just can't wait for this one to molt. It's incredible. Gorgeous to look at, and when I open the enclosurs to feed, it opens up its legs and just lets me set the cricket in there for it. I love the P. irminias. They also may be hard to sex venteally because they are a very unique new world species.

      I have what I believe is a male A. Avicularia that is very calm like that. He was purchased at a pet store where he was handled everyday. A little boy was holding him and swinging him around, running all over the place with this T in his hand. At that point, I took the poor thing from the child, placed him back in the enclosure, lectured the sales associate, and left with the poor thing to give him a home of peace. When I have to open the enclosure, he walks right up to me and try’s to crawl on my hand.

      As far as the sexing goes, some species are much easier. I have been very accurate with almost all of my Poecilotheria’s. Theraphosa’s are generally way to tell too. Yours looks like there is a U shape setting low on the book lung, so I guessed female. What were thinking she/he is?
    • IncoherentScreeching
      @Drea while I'm praying for a female, I really am torn either way. I see no "slit" between the book lungs so that makes me think make. However, this spider is still relatively small. It's 3 inches at most with its legs completely and totally stretched out so it's still very young. I see the "u" shape between the book lungs so that makes me think female. And it's hard to gauge the spacing of the book lungs because it's so small. I can't give a difinite guess, but if I had to, I'd probably say male. It has a pretty small abdomen and is very "leggy." I have 3 more on the way though so surely I'll have at least 1 female out of my lot haha.

      I don't think its body shape or having long legs would point toward it being male. I think your best bet is to get its next molt before it chews on it. I don't see a raging gonoslit but I don't see epiandrous fusilae either. Which is a dark arch of special hairs above the slit. I couldn't tell either way on this pic. I am not that great at ventral sexing and I don't trust the ventral sexing method unless it is extremely obvious. I don't see anything obvious in this picture to point me in any direction as far as sex goes.

      @Goopyguy56 thanks for trying though..I guess I'm just going to anxiously await a molt. This is a fast growing species so it shouldn't be too too long Haha. Anyways, thank you very much for your reply.
