Mecodema atuanui was described from a single male specimen collected in pitfall traps on Mount Auckland (Atuanui), Kaipara Region. It is a medium-length ground beetle that is related to Mecodema spiniferum,[1] which is the only large-lengthed ground beetle species found in the Waitākere Ranges, Auckland, rather than the more geographically close species (M. dunnorum) to the east in Puhoi.
