Kuschelysius, a New Alpine Genus of Eugnomine Weevil (Coleoptera: Curculionidae: Curculioninae) from New Zealand

Abstract

Kuschelysiusnew genus is described for four species, K. hollowayaenew species, K. durusnew species, K. verbalisnew species and K. nitensnew species, which are found in alpine regions along the length of the South Island of New Zealand. The genus most closely resembles members of the genus Eugnomus but is distinguished from them by the presence of a small pair of post-ocular tubercles and by having appressed scales on the dorsal surfaces. Some members of Kuschelysius appear to be flight-capable with well-developed hindwings, while others have reduced hindwings and are presumably flightless. Many specimens have been collected from the flowers of Dracophyllum traversii, Celmisia and other alpine plants, and the guts of examined specimens contained pollen. We hypothesise that the species of Kuschelysius are pollinators of the New Zealand alpine flora.
