Paleospheniscus biloculatus was named after 2 characteristic humeri (AMNH 3341 and 3346) (Simpson 1946) from the Early Miocene Patagonian Molasse Formation which were found near Gaiman in Chubut Province, Argentina. It was the size of a small Gentoo Penguin.

In 2007 P. biloculatus was moved to the genus from Chubutodyptes, the species becoming P. biloculatus.
