Taxonomy
Portlandia was named by Mörch (1857) [Sepkoski's age data: K Sant R Sepkoski's reference number: 159]. It is extant.

It was reranked as Nuculana (Portlandia) by Marwick (1942); it was reranked as Yoldia (Portlandia) by Richards (1962).

It was assigned to Nuculana by Marwick (1942); to Yoldia by Richards (1962); to Nuculanidae by Woodring (1973), Hayami (1975), Moore (1983), Moore (1984) and Wienrich (1999); to Yoldiinae by Coan et al. (2000); and to Nuculoida by Sepkoski (2002).
