Identification.

This and the similarly sized Mecyclothorax teatara share the characteristics of a narrow, subquadrate pronotum and broadly ovate elytra (Figs 23D, 25B), but in Mecyclothorax tutei the pronotal hind angles are more angulate, the pronotal lateral margins less explanate, and the elytra base broader. The pronotal median base is also more punctate, with about 13 punctures each side of midline plus rugose wrinkles laterally, versus 6-8 small isolated punctures each and a smooth surface laterally in Mecyclothorax teatara . The head has a distinct isodiametric mesh in transverse rows covering the vertex. The pronotal disc is covered with a distinct transverse mesh, sculpticell breadth 2 –4× length, and the discal elytral intervals bear a distinct transverse mesh, sculpticell breadth 2 –3× length intermixed with transverse lines. Setal formula 2221; standardized body length 5.3 mm.

Distribution and habitat.

This species is known from 1080 m elevation on Mont Mauru, where the single known female specimen was collected by pyrethrin fogging tangles of dead fern fronds.
