A reexamination of the systematic position of Amitermes brevicorniger, with the description of a new genus (Isoptera, Termitidae, Termitinae)

The systematic position of the South American termite Amitermes brevicorniger is reexamined through the analysis of the morphology of soldiers, workers and digestive tube. The characters examined do not support its inclusion neither in genus Amitermes nor in Synhamitermes, and a new genus, Onkotermes, is described to accommodate this species. This species clearly belong to the Amitermes-group, but its affinities within this group are unclear. The species is redescribed and illustrated, with biological notes and new distribution records.
