According to Webster's Dictionary:

ex·ot·i·ca noun pl ig-ˈzä-ti-kə
Definition of EXOTICA

1:things excitingly different or unusual; especially : literary or artistic items having an exotic theme or nature

2:Objects considered strange or interesting because out of the ordinary, esp. because they originated in a distant foreign country.

And from Wikipedia:

Exotica is a musical genre, named after the 1957 Martin Denny album of the same title, popular during the 1950s to mid-1960s, typically with the suburban set who came of age during World War II. The musical colloquialism, exotica, means tropical ersatz: the non-native, pseudo experience of Oceania (Polynesia, Melanesia, Micronesia, Southeast Asia, and especially Hawaii).[1] Denny described the musical style as "a combination of the South Pacific and the Orient...what a lot of people imagined the islands to be like...it's pure fantasy though."[2] While the South Seas forms the core region, exotica reflects the "musical impressions" of every place from standard travel destinations to the mythical "shangri-las" dreamt of by armchair safari-ers.[1]

So Exotica & Exotic are based in the same definition unless you apply it to a music form.

Exotica Girl = Exotic Girl

John-O give me your definition so I can add it to the list, Sorry to get all "Academic", But this is my understanding
of the words, Exotic & Exotica :P :P :P
