Geographical variation in Tylencholaimus mirabilis (Nematoda: Tylencholaiminae) evidence from South African and Indian populations

Understanding intraspecific variation in nematodes is essential for accurate taxonomy and ecological interpretation. This study examined morphological and molecular variation in Tylencholaimus mirabilis from geographically distinct populations in South Africa and India using an integrative taxonomic approach. South African populations from Limpopo Province were studied using light microscopy (LM), scanning electron microscopy (SEM), and partial sequencing of 18S and 28S rDNA for morphological ch
