Explanation of Names

Dolomedes vittatus Walckenaer, 1837

Identification

Distinguishing Dolomedes vittatus from Dolomedes scriptus males can be rather tricky at times, so here's a couple physical characteristics that I use to tell the two apart:

1.) Generally, the abdominal markings of adult male D. scriptus have a more "sculptured" appearance, whereas D. vittatus have less-pronounced markings.

2.) The two dark-colored spots in the middle of the cephalothorax are almost always more robust in D. vittatus than the more narrow ones found on D. scriptus.

Here are some images from the Guide that might help clarify some of this:

Hope that helped a little...Brett Tyler, 31 December, 2008

Anecdotally, it appears that white stripes along the edges of the carapace and abdomen are only found on males.
