This beetle was named after Val Dunn and her late husband Arthur Dunn for their conservation work in the Puhoi-Warkworth areas of north Auckland. Both the bush reserves were covenanted by the Dunn family so that there were native forest remnants south of the Puhoi River.

Differing from other North Island Mecodema species by the:
- vertexal groove shallow, more impressed laterally, unpunctured, but large dimples laterally;
- prothoracic carina broad the entire length, smooth with 14–17 setae along each side;
- distinctive shape of apical portion of the penis lobe.[1]
