Hi, eguzki. I agree with second Mielczarek's reply. Firstly, it is undoubtedly Phaneropteridae - there are round openings of the acoustic organs on the tibia I as you see. Secondly, it is Leptophyes as it is wingless and has spotted femurs. I've got couple of specimens (male and female) of L.albovittata in my collection caught last summer in Central Russia. Having compared my specimens with that on the picture I tend to say that your grasshopper is L.albovittata male.
Best regard, Sergey.
