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.
Diagnosis[edit]
Distinguished from other North Island Mecodema species by having:
- a lobate labrum;
- vertexal groove defined by punctures along the entire length;
- elytral intervals 3 and 5 significantly broadened than otherintervals;
- the distinctively narrow width of the apical portion of the penis lobe.[1]
Description[edit]
Length 24.9 mm, pronotal width 6.7 mm, elytral width 7.9 mm. Colour of entire body matte black, except coxae and legs dark reddish-brown.[1]
