• Platystethus spiculus

  Platystethus spiculus is a small rove beetle (Staphylinidae) first described from South America in 1840. The species has established an exceptionally broad distribution across the Neotropics and has been introduced to the Galápagos Islands and Tahiti. Its spread to oceanic islands suggests human-mediated dispersal, likely through agricultural or horticultural trade. The species belongs to the subfamily Oxytelinae, whose members are often associated with decaying organic matter and moist microhabitats.
