The specimens have an obliquely truncate declivity which is generally associated with Amasa. However, multiple Asian xyleborine genera have at least one species with a truncate declivity. The species is transferred to  Microperus Wood, 1980because of the following characters: pronotum type 2 (viewed dorsally), antennal club type 3, scutellum not visible and lack of mycangial tufts.
