Type species: Aphodius rugosiceps Harold, 1859 by subsequent designation (Dellacasa 1988).

Diagnosis: Body reddish brown. Head lacking tubercles on frontal suture. Head and pronotum not flattened as in Podotenus. Protibia with three distinct teeth in both sexes. Pronotum broader in
males than females. There is a lot of variation in the pronotal shape between males and females, and between members of the same sex within a series. Females tend to have the base of the pronotum somewhat constricted, males the base often has a notable posterior angle. Elytron lacking apical umbone. Pygidium entirely smooth, unmodified. Metatibia with apical spurs separated by metatarsus.

Remarks: This genus is endemic to the study region and contains two species. A full description and illustrations of Orodaliscoides and its type species are present in Dellacasa and Gordon (1997) and Dellacasa et al. (2001). Orodaliscoides shares many characters with Symphodon, Podotenus, and a few other Australian genera, but has a less flattened body shape, thicker clypeal margin, elytral intervals not alternately modified, both sexes with three protibial teeth, and males with broader pronotum than females. Orodaliscoides appears more closely related to Acrossidius Schmidt in Australia than to other South American taxa. A thorough phylogenetic analysis of the Australian and South American genera is needed to gain a better understanding of their relationships. Specimens of Orodaliscoides are rare in collections but seem to be attracted to light. The natural history of the species in this genus is unknown.
