| Abstract | The genus Corbicula is taxonomically equivocal due to being described with vast morphological dispersion, but narrowgenetic variation. This study aimed to characterise the taxonomy and distribution of the Corbicula in Thailand. The phenotype ofCorbicula was characterised based on morphometric characteristics. Then, mtDNA cytochrome b (cytb) was used to evaluate thegenotype. The study indicates that the morphometric characteristics, namely shell height (SH), shell width (SW), anterior length(AL), posterior length (PL), and length posterior-anterior shell (LPAS), significantly differed between the evaluated samples.Canonical discriminant analysis revealed a significant difference between the morphometric characters by location. The genotypecharacterisation revealed a single species, Corbicula fluminea that inhabited the Thailand freshwaters, regardless of thegeographical range. Phylogenetic analysis using Maximum Likelihood (ML), Neighbour Joining (NJ), and Maximum Parsimony(MP) methods demonstrated haplotype polymorphism. Therefore, phenotype variation of C. fluminea resulted from haplotypepolymorphisms across the geographical range. |
