First Recorded Hawaiian Occurrence of the Alien Ground Beetle, Agonum muelleri (Coleoptera: Carabidae), from the Summit of Mauna Kea, Hawaii Island

Abstract

Adults of the non-native species, Agonum muelleri (Herbst) (Coleoptera: Carabidae) were collected from the summit of Mauna Kea in 2006 and again during 2008, indicating that a population of this European species is established on Mauna Kea volcano, Hawaii island (NEW STATE RECORD). Agonum muelleri is a synanthropic species that has been accidentally introduced from Europe to both the east and west coasts of North America, with the known North American distribution including 24 provinces and states of Canada and the United States. Characters for the adults are provided to permit diagnosis of this non-native species from all other native and introduced carabid beetle species known from Hawaii. Recorded environmental conditions from Mauna Kea summit taken during the months when specimens were collected are consistent with conditions associated with winged flight by A. muelleri individuals in the species’ native European range.
