COMMENTS: Tychus meybohmi sp. n. is very similar to Tychus viti Besuchet, 2011 from which it can be distinguished by its smaller size ( 1.35 mm T. meybohmi , 1.60-1.65 mm T. viti ), by the antennal shape with segments V longer than wide (slightly wider than long in T. viti ), and by the different shape of the ventral portion and dorsal apophysis of the aedeagal median lobe.
