Abstract

Pinacocerus Van Duzee and Yumbera Bickel are reviewed. Pinacocerus is found in Chile and Argentina and comprises two species, Pinacocerus nodicornis Van Duzee and Pinacocerus candiptorumsp. nov. from Chile. Yumbera comprises six species, five from eastern mainland Australia and Yumbera trisignatasp. nov. from Tasmania. The two genera show remarkable parallel evolution in modification of the male antenna.

Résumé

Pinacocerus Van Duzee et Yumbera Bickel sont passés en revue. Pinacocerus se trouve au Chili et en Argentine et contient deux espèces, Pinacocerus nodicornis Van Duzee et Pinacocerus candiptorumsp. nov. en provenance du Chili. Yumbera contient six espèces, cinq de l'est de l'Australie continentale, et Yumbera trisignatasp. nov. de la Tasmanie. Les deux genres montrent une remarquable évolution parallèle dans la modification de l'antenne du mâle.
