Dolomedes Albineus White Banded Fishing Spider - Dolomedes albineus - female

Dolomedes Albineus White Banded Fishing Spider - Dolomedes albineus - Female
Bulverde, Comal County, Texas, USA
July 25, 2008
Size: 4" Leg Span, 1.1" Body
Spotted up on the wall of my balcony.

Not sure if Male or female -

Is it odd that the pedipalp aren’t fat at the ends-? Seems sort of large to be immature or female right? Pictures don't quite indicate, but the pedipalp are even width all the way down, with no bulge or "boxing gloves".

Thought I read that the females were smaller, and this one already seems to be on the large side of the males.

The brick gives an indication of scale, but can submit more photos with measurements if this is curious to anyone.

Thanks for your consideration.

UPDATE: I have since identified it as a female.

I'm going to try to figure this out. I frassed the brick images as they are no longer needed. Dolomedes Albineus usually has a white band across the face, which seems to be missing in your spider. However, it seems that that is not always the case. It also has white wavy hairs on its legs. See these images that has the hairs but not the white band on the face:


That being pointed out... I don't think your spider has the white wavy hairs (more like messy random hairs). What do you think?

And did you mean .75"? That
And did you mean .75"? That brick should be 2.25" tall, and spiders are measured from the tip of the abdomen to the front edge of the dorsal carapace, not including spinnerets, palps, chelicerae, etc. The size listed for most of the spider postings on BugGuide are gross exaggerations, and for a variety of reasons.

Female spiders are usually larger than conspecific males, and in some species they are much larger.

I'm not sure which sex this one is. I don't see an epigynum in your venter shot, but there appears to be some glare from the white background that might be robbing detail from the epigastric furrow. Can you shoot that again with a dark background? Markings look immature to me, but I'm not real familiar with this family.

 
And did you mean .75"? That
Nope. (The brick is 2.75 Inches tall).

In non-technical terms- the spider is 1 1/16" long from the base of the butt, to the eyeballs.
