Most likely blattea indeed but this is still subadult. So you have a side view of this spider?

Thanks, Simeon! I added a lateral view. If that one is not good enough, I could make a new one. She is still alive.

Not sure yet. Is that a tubercle, or a drop? If you are able to raise it, it will be good.

Rients

Tomorrow I will make a new lateral picture. And raising spiders: I have no experience: should I feed her some small insects?

Exactly; Theridiidae are easy (except Episinus). Wait until it makes a web in a well ventilated box (don't forget to give water every few days, whenever it dries). You can put small, partially immobilized insects in the web. Cryptachaea may eat injured ants as well.

Thanks! I will try to keep the spider over in a well aerated vessel. Meanwhile I took some more pictures. You seemed especially interested in a possible papilla at the back of the abdomen? It indeed has a small white papilla there.

Which means that it is for sure Cryptachaea blattea? (Thanks a lot!)
