It is not included G. sabahensis Schimmel, 2003 described on a specimen ♀. According to the description the species presents spaced punctures on pronotum and bidentate apices of elytra, so can be compared with G. longicornis and G. surigaoensis but is immediately separated by the large size (16.7 mm).
