Abstract
INTRODUCTION: Branchiopodataenia bazaletica sp. n. (Cestoda, Cyclophyllidea) is described from the black tern, Chlidonias niger L., after re-examination of material deposited in the helminthological collection of the Institute of Zoology, Ilia State University, Institute of Zoology in Tbilisi, Georgia. METHODS: The cestodes were collected from Bazaleti Lake in Georgia and originally identified as Wardium cirrosa, as labeled on the slides. Cestodes were examined using light microscopy. RESULTS: Detailed examination of the morphology of these specimens showed that they belong to the genus Branchiopodataenia and are described as a new species. The presence of 10 aploparaksoid hooks with an elongate handle, three testes, and chitinoid latch-like structure in the copulative part of the vagina support the assignment of the new species to Branchiopodataenia. The new species has rostellar hooks 48-52 in length, a long, armed cirrus, and long copulative part of the vagina. Branchiopodataenia bazaletica sp. n. differs from its congeners by the size of rostellar hooks and by the shape of the cirrus and vagina.
