I found this one today between large leaves of a (sub?)tropical plant in a hothouse in the southern province of Limburg, the Netherlands.
I first thought of Parasteatoda, but it doesn't look like any of the usual suspects in that genus. Any ideas?

KL=2.5 mm

Hi Simeon,

Is that a hint? Upon hearing tubercle, I think Ero, but surely the prosoma is too dark for one of those?

No, not a Mimetidae but well a Theridiidae !
It should be "aaaCcehprty aabeltt" (you have to put the letters in the good order   ;)

Thanks Pierre,

Then it must be Cryptachaea blattea. Is the species identifiable by habitus?

Normally yes... and the habitus is fully corresponding (the habitat also) !
But to be sure, As Simeon wrote it, you have to verify the presence of a small tubercle situated just posterior to mid-dorsal point.
See Unibe https://araneae.unibe.ch/data/2009/Cryptachaea_blattea

The tubercle is there, although it is rather small. Thanks for your help, Simeon and Pierre!

Thanks Jonathan; the species was only recently found for the first time in the Netherlands.
