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

Distinguished from other North Island Mecodema species by having:

  1. a lobate labrum;
  2. vertexal groove defined by punctures along the entire length;
  3. elytral intervals 3 and 5 significantly broadened than otherintervals;
  4. the distinctively narrow width of the apical portion of the penis lobe. [1]

Description

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]
