Median-joining haplotype networks based on a 687 bp fragment of small subunit rDNA and the first Internal Transcribed Spacer (left) and 631 bp of large subunit rDNA (right) from the newly sequenced individuals of Cichlidogyrus tilapiae from India, aligned with all previously published sequences from this species. Genotypes are represented by circles, with the size of the circle correlating with the number of isolates displaying the respective genotype. Colours denote the countries of sampling localities. Genotypes are connected by lines indicating the number of mutations between them.
