Taxonomy
The genus Rhynchocyclus was introduced in 1860 by the German ornithologists Jean Cabanis and Ferdinand Heine as a replacement name for Cyclorhynchus that had been introduced in 1836 by Carl Jakob Sundevall.[1][2] The name Cyclorhynchus was preoccupied by Cyclorrhynchus that had been introduced in 1829 by Johann Jakob Kaup.[3] The type species is Cyclorhynchus olivaceus Desmarest which is a junior synonym of Platyrhynchos olivaceus Temminck, the eastern olivaceous flatbill.[4][5] The genus name Rhynchocyclus is an anagram of the original name Cyclorhynchus.[6] The latter combines the Ancient Greek κυκλος/kuklos meaning "circle" or "shield" with ῥυγχος /rhunkhos meaning "bill".[7]
