Redeskription von Cyphon gracilicornis Wollaston, 1864 von den Kanarischen Inseln. 30. Beitrag zur Kenntnis der Helodidae (Coleoptera: Helodidae).

Abstract

Cyphon gracilicornis Wollaston, 1864, is rediscribed on the basis of the type material (description and illustration of the genital). Cyphon gracilicornis is regarded as a sister species of Cyphon hilaris Nyholm, 1944. It is very probable that Cyphon lindbergi Nyholm, 1949, is a sister species of this group.
