    Abstract:
    Everted cystacanths of Sphaerirostris lanceoides (Petrochenko, 1949) Golvan 1956 are reported from the Asiatic toad Bufo gargarizans Cantor (Amphibia: Anura) for the first time. The prevalence was 1.96% and the intensity ranged between 1.0-3.0 acanthocephalans. SEM observations revealed the morphology of the gonopore and the presence of a flat, bare region on the apical part of the proboscis. Moreover, S. lanceoides was characterised using molecular approaches by sequencing the ribosomal ITS1-5.8S-ITS2 region and the mitochondrial cox1 gene. The resulting ITS sequences were identical and the cox1 sequences showed a divergence of 0-0.75%. Sphaerirostris lanceoides is the first species of the genus for which the ITS1-5.8S-ITS2 and cox1 loci have been sequenced to aid species identification.
