Deceptively pleasing (8)

I believe the answer is:

specious

'deceptively pleasing' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for specious that I've seen before include "Apparently correct, but actually wrong" , "Seemingly plausible but wrong" , "Attractive at first sight" , "Misleading" , "Superficially attractive" .)

I've seen this clue in The Guardian.
