Type species.

Platynus elegans Brullé, 1838:25 [= Anchonoderus eximius (Audouin), 1836:34]

Way of life.

Size range - 4.5 mm to 8.5 mm; adults of this genus are found on the muddy banks of rivers and streams where they run in the sun from crack to crack in the baked mud. Other ubiquitous species are found throughout the forest where there is sandy soil and thin dry leaf litter, as well as on upper parts of river banks in thin layers of leaf litter. However, most species occur at stream margins among small stones and gravel and in flood debris along upper stream margins. The fact that only 27 species are described from the Neotropics and 11 occur at a single locality at Pakitza, Perú indicates the identification of species is impossible without recourse to types. A taxonomic revision of the group is need.

Distribution.

Arizona and Texas south to Argentina, including many of the Caribbean islands.

Notes.

Currently, 27 described species are assigned to this genus.
