That's why it's important to ask the recruiter, rather than wait to be asked.

That way you can respond to their range with something along the lines of "that sounds roughly what I was expecting", "okay, I'd probably be looking for the top end of that", "that's perhaps a little lower than I was expecting - is there enough room for flexibility for us to be able to continue talking?" or whatever. It's too early in the conversation to be doing a full salary negotiation, you're just making sure the role's at the right level.

There's a big problem with employers writing a senior-sounding job ad for a junior role - the salary range is a much more accurate indicator than a job description.
