Yes I admit that i am also unsure and also have confusion with Backobourkia. However. I do try to be consistent but expect to be corrected at some stage. All three have the white pointy arches at the top of their abdomen. Salsa tends to be hairy. teh hairs tend to be yellow orange and wavy. Araeneus ja,ilitoni is less hairy and tends to have seperate markings along the outside of teh abdomen. Backoborjkia tend to have protruding body parts /
