for key(), make 'lines' into a list:

  xyplot(x~y|SP,data=data,groups=z,layout=c(2,3),
         pch=1:4,lty=1:4,col='black',type='b',
         key=list(x = .65, y = .75, corner = c(0, 0),
                  title="title here", cex.title=.9, lines.title=3,
                  lines=list(pch=1:4, lty=1:4, type='b'),
                  text=list(lab = as.character(unique(data$z)))))
