Sex my Striata

[bluerich74]

I was wondering if anyone might want to help me try to determine the sex of my 3" P.Striata?Unfornately,Im thinking male.What do you all say?Thanks for any input....Rich

 

[usumbaraboy]

it looks male but i wouldnt count female out cause i can kindof see a bump but im not sure

I'd say thats an easy call as a male because of the easy to identify spermicatha, or however they are spelled.

Its spermatheca (or spermathecae plural) - problem is, they are a female structure and they're internal as their function is to store sperm until fertilisation. I'm no expert on sexing Poecilotheria externally but there is a thickening of the epigastric furrow where the external openening to the spermathecae would be so I would say female. However, you should wait for someone actually experienced at sexing Pokies instead of taking my guess.

To be sure, I'd get the next molt and post pics of that.

Im good at sexing with the recent shedded skin but not so great at ventral shots.Hopefully Ill be able to get the next one out of the cage before the spider damages it too much.

It looks like a male..

i would say a male.....

I don't know about gender. But the light colored band between the book lungs would indicate that you have a P.regalis.

I would agree here. Looks like you've got yourself a P. regalis there.

I'm using the wrong name then. What are the male spinerettes that surround the area where it exudes the sperm called?

Juvenile striata's can also have this belly band.

It's funny cause it's so easy to remember that when you'r Greek
theca ~ thiki(modern Greek) ~ case, shack etc.
Sperma ~ you get that....

>>epiandrous glands/fuscillae

Both regalis and striata have yellow leg pattern ventrally. And I can see some yellow on the picture.

Yeah, Robert is right, P. striata can have the belly band as juvs, but it disappears as adults. As for gender, Looks pretty female to me

You're thinking of epiandrous fusilae - which look like dark "nose hairs", usually in a 'V' or 'U' shape, sometimes a patch, but *not* just two white spots.

 

[bluerich74]

So,I guess were kinda split on the sex.Im pretty sure its Striata tho.I know they can have the belly band as a juvie and I got it from a very reliable person.I guess Ill have to wait for the next molt to be sure of the sex.Thanks for all the replies folks.

I might be wrong AGAIN but aren't the epiandrous fusilae used to spin the sperm web? While the sperm comes from the epigastric furrow?
