A taxonomic review of the known Taiwanese taxa of the pericaline Lebiini, this paper includes a key to the genera, keys to species, descriptions, and redescriptions of all species, illustrations, geographic range maps, re-rankings, and new synonymies. In total 34 species are treated, nine of which are described as new. A new genus and new species are as follows: Bellavalentis gen. n., (type species Dolichoctis kuzugamii Shibata, 1967); Amphimenes absensacidus sp. n.; Amphimenes beichatiensis sp. n.; Amphimenes carinacaulis sp. n.; Catascopus (s. str.) asaharti sp. n.; Catascopus (s. str.) viridiorchis sp. n.; Coptodera (Coptoderina) occulta sp. n.; Dolichoctis badiadorsis sp. n.; Dolichoctis dilatata sp. n.; Moctherus obscurabasis sp. n. After close examination of the type material of several species, we were able to determine that Coptoderina chaudoiri anguilipennis (Nakane and Okhura) is a junior synonym of Coptodera (Coptoderina) chaudoiri Andrewes, syn. n. and Coptodera nobilis Jedlička is also a junior synonym of C. chaudoiri, syn. n. Dolichoctis striatus formosanus Habu is a junior synonym of Dolichoctis rotundata (Schmidt-Goebel), syn. n. Dolichoctis (Mochtherus) uenoi Habu is a junior synonym of Mochtherus luctuosus Putzeys, syn. n. Pericalus formosanus Dupuis was recently ranked as a subspecies of Pericalus ornatus formosanus Dupuis. After consideration of the several consistent taxonomic characteristics and also considering its allopatric distribution with all other species of Pericalus, we believe Pericalus formosanus Dupuis to be a valid species, stat. resurr. The monobasic genus Pseudomenarus (type species Pseudomenarus flavomaculatus Shibata, 1964) is established as conspecific with members of the genus Formosiella Jedlička, 1951, comb. n. Species previously recorded from Taiwan that are not present here include: Amphimenes piceolus Bates; Catascopus aequatus Dejean; Catascopus facialis (Wiedemann) Coptodera interrupta Schmidt-Goebel Coptodera flexuosa Schmidt-Goebel and Peripristus ater (Laporte). The pericaline taxa of Taiwan are arranged in 14 genera, five subgenera, and 34 currently known species. Notes on collecting circumstances, habits, and habitat are included when known.
