Can you identify these chiles on sale in Serbia and Macedonia?
I've now found them on sale in a posh supermarket in Skopje, Macedonia. This time labelled:




  потекло
  скопско
  
  пиперки везени
  
  благи / кг


Which Google Translate massages into:


  origin
  Skopje
  
  peppers embroidered
  
  mild / kg


So an answer is "пиперки везени" or "embroidered peppers", for at least one name used in at least one country. Here is a close-up photo giving a better look at the striations:
