Fishing Spider - Dolomedes scriptus - female

Fishing Spider - Dolomedes scriptus - Female
Weare, New Hampshire, USA
August 19, 2005
Size: 2 in
This spider popped out on me when I was raising the outboard motor of our fishing boat. She positioned herself nicely on a support, but only let me take one picture before crawling underneath it. Im pretty sure its a D.tenebrosus, but anyone feel free to correct me, and if you can provide a sex its much appreciated as well.

She :)
Nice photo. This certainly looks like a she... and is definitely a species of Dolomedes. I was looking through the "Golden Guide" (to check if there were any other identifable differences for male/female), and noticed...

Could this be a D. scriptus rather than D. tenebrosus? The "supposed" visual differences are the stripes that start above the posterior median eyes, and moves backward down the head, the distinct looping pattern at the anterior portion of the abdomen, and the pronounced white lines along the black "W"s on the abdomen. Both spiders look similar and have the same ranges (so simliar that a single photo might not be conclusive), but T. scriptus seemed like a better "visual" match.

This is just a point of curosity... (I tried quickly searching the web for confirmation (text and/or photos), but nothing that was conclusive one way or the other, except to look at the very minute details of their reproductive structures...) :)

I would probably just mark it as a Dolomedes genus.

 
Thanks
I appreciate the detail with which you examied the pic, and it seems youre right, D. scriptus does seem a better match. For the sake of accuracy I think your suggestion about moving it to the genus section of the guide sounds good, however Im having trouble moving images right now,so if someone gets a chance to do it before me, feel free

Again thank you for the help
