It is a local surname in Southern ITALY, extremely rare.
Not more than 10 families in CALABRIA, near Cosenza,and in SICILY, in Catania.
This surname is quite near to a greek surname PALIKARAS so like quite a few sicilian or calabrian surnames could derive fro greek dialects still spoken in some areas of Southern Italy.
I ignore the meaning.
See the italian white pages:
www.paginebianche.it (google)
and then bisdes the surname write CALABRIA and SICILIA or the initial letters of COSENZA, CS and CATANIA, CT
