Plesiadapiforms represent the first radiation of Primates, appearing near
the Cretaceous-Paleogene boundary. Eleven families of plesiadapiforms are
recognized, including the Paromomyidae. Four species of paromomyids from
the early Eocene have been reported from Europe: Arcius fuscus, Arcius
lapparenti, and Arcius rougieri from France, and Arcius zbyszewskii from
Portugal. Other Arcius specimens from the early Eocene are known from
Masia de l’Hereuet (Spain), Abbey Wood (England), and Sotteville-sur-Mer
(Normandy, France). A cladistic analysis of the European paromomyids has
never previously been published. A total of 53 dental characters were
analyzed for the four Arcius species and the specimens from Spain,
England, and Normandy. The results of a parsimony analysis using TNT agree
with previous conceptions of A. zbyszewskii as the most primitive member
of the genus. Also consistent with existing hypotheses, Arcius rougieri is
positioned as the sister taxon of A. fuscus and A. lapparenti, and the
results suggest that the fossil from Normandy is A. zbyszewskii. However,
the English fossil pertains to a primitive lineage, rather than grouping
with A. lapparenti as had been suggested; as such it is recognized here as
a distinct species (Arcius hookeri). The Spanish fossils cluster together
with the French species, but do not show the previously proposed special
relationship with A. lapparenti, and are sufficiently distinct to be
placed in a new species (Arcius ilerdensis). Arcius is recovered as
monophyletic, which is consistent with a single migration event from North
America to Europe around the earliest Eocene though the Greenland land
bridge.
Phylogenetic hypotheses of relationships of Arcius including A.
ilerdensisFive most parsimonious trees once Arcius ilerdensis n. sp. is
included. The strict consensus for these five trees is shown in Figure
