An account of the Anthicidae (ant-like flower beetles) from the Lesser Sunda Archipelago (politically shared between Indonesia & Timor Leste) is presented for the first time. Thirteen species new to science are described and illustrated: Anthicomorphus badengsp. nov. (Bali), Anthicus (s. str.) miroshnikovisp. nov. (East Java, Lombok, Timor Leste), A. (s. str.) renschisp. nov. (Flores), Anthelephila anthophilasp. nov. (Timor Leste), A. barsevskisisp. nov. (Timor Island), A. nusatenggarasp. nov. (Lombok), A. tamborasp. nov. (Sumbawa), Macratria marusp. nov. (Pura Island, Alor Archipelago), Sapintus degiovanniisp. nov. (Timor Leste), Pseudotomoderus reidisp. nov. (Timor Leste), Tomoderus balianussp. nov. (Bali), T. dompusp. nov. (Sumbawa), and T. vulcanicussp. nov. (Lombok). Three new combinations (Floydwernerius bolmi (Uhmann, 1997) comb. nov. from Stricticomus Pic, 1894; Pseudocyclodinus denisonii (King, 1869) comb. nov. from PseudoleptaleusPic, 1900; Pseudocyclodinus dilutus (Pic, 1901) comb. nov. from Papuanthicus Telnov, 2006) are proposed, and three new synonyms (Anthicus bisbicinctus Marseul, 1886 = A. robustusPic, 1902syn. nov.; Nitorus bangi (Pic, 1895) = Anthicus mollinusKrekich-Strassoldo, 1930syn. nov., = A. thienemanniHeberdey, 1931syn. nov.) are proposed. New species records for Alor, Bali, Lombok, Sumbawa, Timor, and Yamdena are presented. An annotated bibliography and checklist of the Lesser Sunda Islands anthicids are presented. Comparative morphology of PseudocyclodinusTelnov, 2003 and Papuanthicus Telnov, 2006 is briefly discussed. The genus FloydwerneriusTelnov, 2003, previously considered restricted to the Australian Region, is reported from the Lesser Sunda Islands. In total, 50 species and subspecies of Anthicidae are confirmed for the Lesser Sunda Islands.
