Type species: Scarabaeus fimetarius Linnaeus, 1758 by subsequent designation (Latreille 1810). |
| |
...... |
|
Remarks: The genus Aphodius is a large and taxonomically difficult group that is currently in the process
of being re-classified into dozens of genera. We found two species representing two subgenera of Aphodius as
occurring in southern South America. Both of these species are introduced to southern South America and
native to Europe and Africa. |

Subgenus Aphodius (Calamosternus) Motschulsky, 1859
Calamosternus Motschulsky, 1859: 156.
.
Type species: Scarabaeus granarius Linnaeus, 1767 by monotypy.
Synonyms: Megalisus Mulsant and Rey, 1870: 209; type species: Aphodius stercorarius Mulsant and
Rey, 1870 by subsequent designation (Dellacasa 1988). Pseudesymus d’Orbigny, 1896: 218; type species: Aphodius lucidus Klug, 1845 by monotypy.
Diagnosis: Color uniformly black. Body robust. Head trituberculate. Pentagonal scutellum
usually depressed below the surface of the elytra. Metatibia with apical spurs separated by metatarsus.
Remarks: Full description and illustrations of Calamosternus and its type species is present in Dellacasa
et
al. (2001).

Subgenus Aphodius (Labarrus) Mulsant and Rey, 1870
Aphodius (Labarrus) Mulsant and Rey, 1870: 516.
.
Type species: Scarabaeus lividus Olivier, 1789 by monotypy.
Synonym: Aphodius (Pseudocalamosternus) Balthasar, 1936: 1; type species: Aphodius (Pseudocalamosternus) rigidus Balthasar, 1936 by monotypy.
Diagnosis: Body robust. Pale brown and black color pattern is similar only to members of Aidophus in
South America. Head with tubercles on frontal suture. Pronotum lacking basal
marginal line. Scutellum pentagonal. Metatibia with apical spurs separated by metatarsus.
Remarks: A full description and illustrations of Labarrus and its type species are present in Dellacasa et
al. (2001). Members of the genus Aidophus in South America have similar color pattern to Aphodius (Labarrus)
species. Aidophus are easily distinguished by lacking the frontal tubercles, having a triangular
scutellum, and in having the metatibial spurs adjacent.
