Ningalooia psammopercae n. g., n. sp. is described from the intestine of the Waigieu seaperch
Psammoperca waigiensis Cuvier (Perciformes: Latidae) on the Ningaloo Reef, Western Australia. The new genus and species are distinctive within the Acanthocolpidae for the combination of the absence of enlarged spines around the oral sucker, a blind ending H-shaped intestine and a deeply lobed ovary.
