As a first step toward a re-evaluation of species boundaries in this genus, mitochondrial sequence variability was analyzed in 51 samples collected from Okinawa, New Caledonia, and the Philippines. Four clusters of sequences were detected that showed little concordance with species currently recognized on a morphological basis. The most likely explanation is that the skeletal characters used for species identification are highly variable (polymorphic or phenotypically plastic); alternative explanations include introgression/hybridization, or deep coalescence and the retention of ancestral mitochondrial polymorphisms. In all individuals sequenced, two copies of trnW were found on either side of the atp8 gene near the putative D-loop, a novel mitochondrial gene arrangement that may have arisen from a duplication of the trnW-atp8 region followed by a deletion of one atp8. specialized Cnidaria Scleractinia Taxonomy Systematics Mitochondrial genome 034 27 4 789-794 2008 0722-4028 https://www.documentation.ird.fr/hor/fdi:010044101 10.1007/s00338-008-0407-2 0722-4028 [F B010044101] https://www.documentation.ird.fr/hor/fdi:010044101 https://www.documentation.ird.fr/intranet/publi/2008/12/010044101.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2009-01-09 2017-08-23 fdi:010044101 fre
