Diagnosis. Body length 1.8–2.0 mm, maximum body width 1.2–1.3 mm . Body oval ( Fig. 10 ), strongly convex. Dorsal back, pronotum and elytra with lateral dark brown margin. Surface of pronotum and elytra with sparse white setae. Legs brown. Male genitalia ( Fig. 14 ): Aedeagus 0.5 mm long. Median lobe slender, wide basally, slightly narrowing towards midlength, apical rounded; parameres slightly shorter than median lobe or as long as median lobe, weakly narrowing at apex, narrowing towards basal, basal truncate. Differential diagnosis. Laccobius politus is similar to Chinese species of L. hainanensis Jia, Gentili & Fikáček, 2013 , L. martini Jia, Song & Gentili, 2013 and L. motuoensis Jia, Chen & Fikáček, 2019 . It can be differentiated from them by the dorsal surface with sparse white setae, median lobe indistinctly constricted subapically, and parameres narrower than median lobe, rounded apically. This species is the only inhabitant of wet rocks in Taiwan , as well as that only representative of the subgenus Glyptolaccobius in Taiwan . Therefore, this species can be easily distinguished from other Taiwanese species.
