We detected for the first time a hybrid form between <i>T. saginata<\/i> and <i>T. asiatica<\/i> in Preah Vihear Province, Cambodia. An adult tapeworm specimen, i.e., 75 cm long strobila without scolex, was expelled from a 27-year-old man after praziquantel medication and purging. It was morphologically indistinguishable between <i>T. saginata<\/i> and <i>T. asiatica<\/i>. Several proglottids were molecularly analyzed to confirm the tapeworm species. The mitochondrial gene encoding cytochrome <i>c<\/i> oxidase subunit 1 (<i>cox<\/i>1) and nuclear genes encoding elongation factor-1\u03b1 (<i>ef1<\/i>) and ezrin-radixin-moesin (ERM)-like protein (<i>elp<\/i>) were sequenced, and a single-allele analysis was performed to confirm the haploid genotype. The results revealed that our sample showed a discrepancy between the mitochondrial and 2 nuclear genes. It possessed homozygous sequences typical of <i>T. saginata<\/i> at <i>cox<\/i>1 and <i>ef1<\/i> loci. However, it was heterozygous at the <i>elp<\/i> locus, with 1 allele in <i>T. asiatica (elpA)<\/i> and 1 in <i>T. saginata (elpC<\/i>), which indicates that it is a hybrid between <i>T. saginata<\/i> and <i>T. asiatica<\/i>. The present results confirmed the presence of a hybrid between <i>T. saginata<\/i> and <i>T. asiatica<\/i> in Cambodia and strongly suggest the existence of also \u2018pure\u2019 <i>T. asiatica<\/i>
