Spider (bites all over)

husband been in atlas mountains morocco. Home and woke next morning covered in huge red circular areas of swelling with outter red area. I gv him one allergy tab and three hours later body clear! Slept last night woke one big new one.. I saw this weird 'bat' looking spider on wall asleep with legs in oval shape around its body. This pic is of it in a glass I got it in. Is it foreign please ? What is it ? He has never had a reaction to anything like this before ! Thankyou experts x
