A new species of Rhantus diving beetles from the wetlands of the City of Bogota and surroundings (Coleoptera, Dytiscidae, Colymbetinae)

Abstract

The Colombian species of the genus Rhantus are reviewed. Rhantus bogotensis sp. nov. is described and illustrated, based on specimens collected in the Altiplano of the Bogota region. It is compared with the similar species Rhantus franzi, R. vicinus, and R. crypticus. The Ecuadorian species Rhantus crypticus was found for the first time in the highlands of Nariño department. This is a new record for Colombia. Five species of Rhantus are presently known from Colombia.
