Abstract

AbstractCurrently comprising 12 species infecting the gastrointestinal tracts of diurnal raptors (Falconiformes, Accipitriformes), species of Cladotaenia are diagnosed by their branching uterus, testes in two fields reaching the same level anteriorly, and small rostellum armed with taenioid hooks arranged in two rows. In this study we describe a new species of Cladotaenia recovered from a number of Australasian harriers Circus approximans, from the southern half of South Island, New Zealand. The new species is distinguished from other species by its single circle of hooks. It is closest, morphologically, to C. circi, but differs in the shape of the terminal proglottids and the number of uterine branches. Sequences of 28S and cox1 gene are presented. Genetically, Cladotaenia anomalan. sp. is closest to Cladotaenia globifera but differs morphologically in the size of the suckers, testes and eggs. This description constitutes the first record of a Cladotaenia species in New Zealand. We discuss some potential routes this parasite may have taken to arrive in New Zealand.
