makes you think its a female? you cant really see it in the pics but the end of its pedipalps have a slight bulge like what ive seen on other large immature male Phids

looks like a female to me, and I magnified with IE, but since you have the spider, I will take your word for it. Maybe post a clear image of the pedipalps?
Also, are you raising any Promyrmekiaphila?

after an hour and 200 photos i think i managed to get 2 decent palp pics, what do you think?

I think it is an adult female at that size. I also see the bulge, but if a male I believe it would be indictive of an antepenultimate male.

Sorry I didn't mention this before (didn't think about it), it possibly would have saved you a lot of time and trouble, but check out the venter and see if it has an epigynum.

antepenultimate thats the word i can never remember, wanted to say that instead of immature. i hope your right and im wrong on the sex, ive never seen these before so really have no clue what a females pedipalp looks liek in comparison to an antepenultimate males. any idea when their breeding season is?

i had thought about trying to ventrally sex it but really not sure what its post to look like on them.
thanx for all the help Jeff

tips from Jay.

In FL, they breed all year, and all stages can be collected any time.
Not sure about your area, but I think breeding is more seasonal, probably during the summer months.
Audax don't belong there anyway! They're introduced in CA.

"ive never seen these before so really have no clue what a females pedipalp looks liek in comparison to an antepenultimate males"

Identical. Palps of a subadult and adult male are greatly swollen, but immatures can't be reliably sexed.

Here's a comparison of changes in palp shape of a male princeps:

Immature; antepenultimate (no change, also considered immature); subadult; adult.


To determine an adult female you need to flip it over and look for the presense of an epigynum between the book lungs.

Easier said than done with a living specimen. :-) Might be handy to place the subject right-side up on a mirror. My money is on adult or subadult female. Jeff already mentioned the size, and I think this one looks a little too hairy to be immature.

yeah ive discovered they arnt very grabable, ill give the mirror trick a try since i cant get a clear shot through the containers ive tried using. thanx for the visual aids

far no luck getting palp pics but ill keep trying.

sadly the Promyrmekiaphila mama and babies i had died on me during the heat wave some months back
