Trapdoor spider

Iberesia machadoi

Description:

The body is clearly split into two parts, with the front part being almost completely black, and the back part brown but slightly translucent, soft and sac-like. The front 'antenna' clearly have two stingers, like scorpions, on the end. These are pedipalps, indicating this is a male.

Notes:

I fished this one out of a swimming pool at work. He twitched a little but I think he was dead.

ID still a little tentative, but I think it's right. This species is found specifically in Portugal, which is a plus! :)

So, this fellar looks very much like a type of trapdoor spider, family Ctenizidae, and it's a male because it has the pedipalps at the front. And it looks like a California trapdoor spider, but can't be because it was found in Europe.... More research needed! :)

rubens, o tamanho é 5cm, mais ou menos. É definitivamente uma aranha diferente! :) Obrigado!
Stephanie, thanks for the comment and the help! :) I will check that out now. I do have more unidentified spiders, if you wish to take a look at those some time...? :)

Nice find! This spider is a mygalomorph because the fangs point straight down. If it were an araneomorph (which includes the Clubionidae), the fangs would cross each other. I hope this helps!
