Abstract This study describes Renicola websterae n. sp. , a newly identified kidney fluke (Renicolidae: Trematoda) infecting two penguin species from New Zealand, the little blue ( Eudyptula novaehollandiae ) and Fiordland crested Eudyptes pachyrhynchus ). Morphological molecular analyses, including phylogenies based on cox1 28S genes, confirmed distinctiveness of R . Key morphological features were discerned to be statistically comparable across five developmental stages, facilitating detailed characterization even in less mature specimens. A putative second, genetically distinct was penguins intermediate fish hosts, indicating potential trophic link, partly completing known life cycle. We discuss fact that flukes have only been found these not other Zealand species, ecological host-specificity factors likely influencing parasite distribution. work represents first record named second worldwide.
