The genus

Phanaeus

(Scarabaeidae: Scarabaeinae) forms an important part of the dung beetle fauna in much of the Western Hemisphere. Here a phylogeny for

Phanaeus

, including 49

Phanaeus

sp., and 12 outgroup taxa, is proposed. Parsimony analysis of 67 morphological characters, and one biogeographical character produced 629 equally parsimonious trees of 276 steps.

Oxysternon

, the putative sister taxon is nested well within the subgenus

Notiophanaeus

, implying that

Oxysternon

might ultimately need to be synonymized with

Phanaeus

. Species groups of Edmonds (1994) recovered as monophyletic are

paleano

,

endymion, chalcomelas

,

tridens

,

triangularis

, and

quadridens

. An 'unscaled' equal weighting analysis yielded 57,149 equally parsimonious trees of 372 steps. The strict consensus of these trees yielded a monophyletic

Phanaeus

with the inclusion of

Oxysternon

. Bootstrap values are relatively low and some clades are unresolved.
