In the article: long after Pepi II, traditionally considered the last Old Kingdom pharaoh.
They skipped https://en.wikipedia.org/wiki/Merenre_Nemtyemsaf_II and possibly https://en.wikipedia.org/wiki/Netjerkare_Siptah that are regarded as the last (or the last two) of the https://en.wikipedia.org/wiki/Old_Kingdom_of_Egypt
Perhaps they have another tradition?
The pharaonic list based on the surviving copies of Manetho are a little sketchy -- Steven Quirke built a list of pharaohs, still using the "kingdom" and "dynasty" divisions, but only including those kings with probable matches in surviving monuments. Those two names are from the Seti temple at Abydos, upon which the Manetho list may have been based, iow, it's a New Kingdom-era compilation, and not left by those alleged pharaohs themselves.
