I'm in the desert southwest US.
at first this looked like a crab spider, it is small/medium,9mm body
first pair of legs are 30mm as are the 4th pair.second and 3rd are
slightly shorter with some hairs. the cephalothorax is nearly round,
with a smaller 'boxy' deformed abdomen.(a little like a pholcidae)
it is complety light tan. it has a single eye cluster centerd at the anterialdorsal that resembles a tiny blackberry (4 larger 4 smaller)
the most peculiar thing,is it lacks either chelicera,or pedipalps
it has 2 extentions(like palps) at its anterior that extend up and
forward these are folded double about 4mm at the ends they curve
inward.they look like a pair of tiny 'backhoes',and may have small
fangs at the end. I can't seem to upload pix,but could e-mail
this seems to be very docile,but fairly quick to go defensive.
any clues as to info or taxonomy is greatly appreciated.
Update: I believe I've found it:
Filistatidae
Kukulcania
hibernalis
male
aka, southern house spider.
this is the first male I've seen,much less
in the desert.
Update 2: thanks Kitty and Paul
