Taxonomy
Fifteen cranio-dental specimens of this species were collected from the island between the years 1933-73.During an expedition to Maboko Island in 1982–83, paleoanthropologist Martin Pickford recovered more than a hundred small catarrhine fossils. Among them, described the new genus and species Nyanzapithecus pickfordi, characterized by several dental specializations, and also transferred the Rangwapithecus species R. vancouveringi to the genus renaming it N. vancouveringorum. Nyanzapithecus was considered closely related to Rangwapithecus and Mabokopithecus based on dental similarities, and an early relative of Oreopithecus bambolii. Nyanzapithecus was originally included in Oreopithecidae before being transferred to Proconsulidae. described a new species, N. harrisoni, from Nachola, Kenya.
considered Mabokopithecus clarki congeneric and even conspecific with N. pickfordi and thus renamed the latter Mabokopithecus pickfordi/clarki and Kunimatsu's species M. harrisoni.
