___ Rica (5)

I believe the answer is:

costa

(Other definitions for costa that I've seen before include "and 5 Down: Spanish holiday destination" , "Rib or rib-like structure" , "Rib (Botany, Zoology)" , "A Spanish coast, may be Del Sol" , "__ Brava, region of northeast Spain" .)

I've seen this clue in The Washington Post, the King Feature Syndicate, the Penny Press, the LA Times, The New York Times and the Universal.
