Platyrhacinae

Platyrhacinae is a subfamily of scarab beetles within the family Scarabaeidae. Members of this subfamily are primarily found in the Neotropical region. They are characterized by their flattened bodies and often distinctive pronotal sculpturing. The subfamily contains several genera, with Platyrhachis being a prominent example.

The diet of Platyrhacinae species is not extensively documented, but like many scarab beetles, it is presumed to involve decaying organic matter, plant material, or possibly fungi. Their larvae are typically fossorial, developing underground in soil or compost. Adult beetles can be found in leaf litter, under bark, or in association with decaying wood.

The taxonomy of Platyrhacinae has undergone revisions, and its precise phylogenetic placement within Scarabaeidae continues to be a subject of scientific study. Their relatively inconspicuous nature and specialized habitats mean that many species may be poorly known or undescribed. Conservation status information for most Platyrhacinae species is generally lacking due to limited research and awareness. Further ecological and taxonomic research is needed to fully understand the diversity and role of this subfamily in Neotropical ecosystems.
