ABSTRACT Haliotis discus and Haliotis diversicolor are economically important abalone species in northern and southern China, respectively. Two subspecies have been recognized for each species, namely, H. discus discus and H. discus hannai, and H. diversicolor diversicolor and H. diversicolor supertexta. The aim of this study is to elucidate the genetic differences between the two species, and their subspecies, based on sequence analyses of nuclear DNA (first internal transcribed spacer of ribosomal RNA (ITS-1) and 18S rRNA) and mitochondrial DNA (16S rRNA and cytochrome oxidase I (CO1) gene). The two species are identical in their 18S rRNA sequences but differ in their ...
