Taxonomic classification
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Insecta

- Genus: Odontopsammodius (established by Arrow, 1910)
General description
Odontopsammodius is a genus of small dung‑feeding scarab beetles. Members of this genus are typically 2–5 mm in length, with a compact, oval body shape characteristic of many aphodiine beetles. The pronotum and elytra often bear fine punctures and subtle striations; coloration ranges from brown to blackish tones.
Species diversity
The genus comprises several described species (the exact number varies among taxonomic catalogs). Representative species recorded in major databases include:
- Odontopsammodius aeneus
- Odontopsammodius afrotropicus
- Odontopsammodius argentinae
- Odontopsammodius capillatus
- Odontopsammodius curvatus
(These examples are drawn from the Integrated Taxonomic Information System [ITIS] and the Global Biodiversity Information Facility [GBIF]; they illustrate the range of species without asserting an exhaustive list.)
Geographic distribution
Records in GBIF and related biodiversity portals indicate that Odontopsammodius species occur throughout the Americas, from the southern United States and Mexico through Central America to parts of South America (e.g., Brazil, Argentina). Some species have also been reported from African regions, reflecting a primarily tropical and subtropical distribution.
Ecology and habitat
As aphodiine dung beetles, Odontopsammodius species are commonly associated with herbivore dung, where they feed and develop. They are often found in pastures, grasslands, and forest clearings where fecal material is present. Their ecological role includes dung decomposition and nutrient recycling.
Taxonomic notes
The genus was first described by Gilbert J. Arrow in 1910. Subsequent revisions of the Aphodiinae have retained Odontopsammodius as a distinct genus based on morphological characters such as the shape of the mandibles, the configuration of the clypeus, and the structure of the male genitalia.
