Abstract Variatiowna s assesseadm ong mitochondrialD NAs (mtDNAs) from geographically dispersedi ndividuals of two specieso f white-eyes( Zosteroplsu teaa nd Z. lateralisi)n Australia.T he survey revealed high levels of intraspecificd ivergence.T he mtDNA of Z. lutea was paraphyletic; eastern samples were more closely related to eastern Z. lateralis than to western Z. lutea.T he mtDNA of Z. lateraliss howed a major phylogenetic break within the distribution of one subspeciesZ, . I. halmaturinaa, nd was relatively uniform acrossf our subspeciesd istributed along the eastc oasto f Australia.T he discordanceb etween speciesb oundaries and the distribution of mtDNA haplotypes is probably due to historical hybridization. The poor correspondenceb etween subspeciesb oundaries and mtDNA discontinuities in Z. lateralisim plies that patterns of morphological variation may reflect local processesm ore than evolutionary history. In a sample of the morphologically divergent island race, Z. I. chlorocephalam, tDNA haplotypesw ere identical to thosef ound on the adjacentm ainland. However, the frequencies of mtDNA variants differed considerably between the two places. These data suggest that the island race is recently derived from the mainland, but that current gene flow is rare. ReceivedI July 1991,a ccepted23 February1 992.
