Mecodema is a genus of large flightless ground beetle (Carabidae) endemic to New Zealand. The genus is very diverse compared to the other three genera in the subtribe Nothobroscina. Mecodema is the only nothobroscine that is geographically widespread across both the North and South Islands, as well as numerous offshore islands.
Bembidion is the largest genus of beetles in the family Carabidae by number of species. All species are small and move very fast. Most of them live close to water. The genus has a biantitropical distribution, meaning they are found in both the Northern and Southern Hemispheres, but not in the tropics. In warmer regions it is substituted by closely related Tachys and other genera.

He was a strong proponent of the glacial refugium hypothesis and made use of the framework to explain the distribution patterns of Scandinavian beetles.
