Distinguishable from other North Island Mecodema species by having: (1) the vertexal groove absent, except a few wrinkles sparsely distributed laterally; (2) asetose punctures of elytral striae stellate (star-shaped) in the apical third (Fig. 3, Seldon & Pou 2024); and (3) regarding the apical shape of the aedeagal lobe, the form of the left paramere is distinctive with long setae extending along ⅘ of the ventral edge (Fig. 2, LP, AL, Seldon & Pou 2024).
