I found this spider near Paramaribo, Suriname, February '17.

Anyone for an ID?

Thanx,
Klaas

In the mean time, I think this could be Dolomedes elegans. Last February (22-2-'18) I found one 'skating' on the water of a puddle in the road on Brownsberg. It looks like the same species.

I agree on family Pisauridae, with D. elegans as a serious contender. I got difficulties finding good online photos of this species as well as of Thaumasia spp. though.

Cheers, Auke :)

For sure one of family Pisauridae.

I think Thaumasia sp. is possible - some of those have an extensive tuft of long hairs either side of their chelicerae when viewed frontally, making them look like they have something of a moustache! Am i seeing something like that on the first photo?

As far as i see for D.elegans, there's been no investigation about it since the original description.

I'm expecting several people on this forum read french much better than I do, anyway for that here's a few bits Taczanowski, 1874 has to say about D. elegans. How does that read to you all versus the images?

Corselet circulaire, brun rougeâtre, liseré de blanc; abdomen brun à dos bordé et tacheté de blatte; pattes longues, brunes rougeâtres. Long. FEM 14 mill., pattes antérieures 34 mill., pattes postérieures 37 mill.

Coloration. Le corselet est brun roussâtre, bordé le long des côtés d'un mince liseré d'un blanc éclatant. Le dos de l'abdomen est brun, parsemé de poils roussâtres et bordé de chaque côté d'une belle raie blanche, dont chacune s'élargit un peu en arrière, sans se joindre; au milieu il y a trois paires de grosses taches blanches, dont les intermédiaires sont les plus petites et les plus proches entre elles, les postérieures les plus grandes et les moins régulières; outre cela il y a encore, le long de la ligne médiane cinq paires de plus petites et proches entre elles. La plaque sternale et les hanches de toutes les pattes sont de couleur fauve roussâtre. Le ventre gris, parsemé de poils blanchâtres. Les pattes et les pattes mâchoires sont de la couleur du corselet. Tous les yeux jaunes d'ambre, situés sur une tache d'un brun noirâtre.

Plusieurs individus des deux sexes et de différents âges, de Cayenne est de Saint Laurent de Maroni.
