The answer is Starveling.
All the other members of the play-within-a-play in Shakespeare's Midsummer Night's Dream are represented in the clues here:
http://en.wikipedia.org/wiki/List_of_postcodes_in_Tasmania 7054 Snug (this is what tipped me off to the rest of them)
With this in mind, I looked up http://en.wikipedia.org/wiki/A_Midsummer_Nights_Dream to find a list of the players.
Looking up the apples clue at http://en.wikipedia.org/wiki/Malus led to http://en.wikipedia.org/wiki/Maloideae. I saw the "japanese quince" in the sidebar and quickly located the regular quince and verified it was unique.
Quince: http://en.wikipedia.org/wiki/Cydonia_%28genus%29
From there it wasn't hard to look up both sand sharks and Mona Iguanas to find they both had Snout in common.

The only 2 left were Starveling and Bottom. A quick google of en.wikipedia.org of both Starveling 1977 and Bottom 1977 revealed that it was Bottom! Discovery in Illinois in 1977: Bottom quark (http://en.wikipedia.org/wiki/Bottom_quark)
