I use Mastronarde’s declension paradigms: http://socrates.berkeley.edu/~ancgreek/paradigmsU/paradigms_U.html

But I can’t identify an appropriate paradigm. The closest I can come is the incomplete υἱός. I can’t believe Mastronarde would let me down like this!

Does anybody know what paradigm I am to use?

Thanks in advance.

Ah, good. I was just thrown off by LSJ giving the uncontracted form. Thanks.
