Mecyclothorax globosus Britton 1948

This species is broadly distributed on Monts Marau and Aorai, with recorded localities from 1100–1380 m elevation on the former, and 1067–1900 m elevation on the latter. Based on pyrethrin fog samples, these beetles occupy moss-covered Weinmannia growth, ferns (both low ferns such as Dicranopteris, and also Cyathea tree ferns), and the axils of Freycinetia plants, perferrably dead and rotting, the more likely to provide food sources such as dipteran larvae. During recent surveys, of the 318 specimens of Mecyclothorax collected on Mont Marau, Mecyclothorax globosus individuals accounted for 151.
