Most similar to Mecyclothorax cooki Perrault, sharing: 1, moderately transverse pronotum, MPW/PL = 1.25; 2, straight to slightly sinuate pronotal lateral margin anterad obtusely rounded hind angle; 3, well-indicated parascutellar striole; 4, transverse-mesh elytral microsculpture; 5, two dorsal elytral setae; and 6, convex elytral intervals. Both species are characterized by a 2221 setal formula, however the pronotal hind angles are more rounded in Mecyclothorax tutei and the pronotal base more constricted; MPW/BPW = 1.42 for Mecyclothorax tutei, versus 1.37 for Mecyclothorax cooki. Standardized body length is somewhat smaller in Mecyclothorax tutei; 5.3 mm versus 5.7 mm for Mecyclothorax cooki. (Liebherr, 2012).
The lone specimen of this species was found in tangles of living and dead fern fronds in low-stature wet montane Weinmannia and Metrosideros forest at 1080 m elevation. The beetle was collected from a beating sheet held under fronds that were sprayed with synthetic pyrethrin. The single specimen of Mecyclothorax toretore and a series of Mecyclothorax pirihao were also found using this method at this elevation. (Liebherr, 2012).
