Four new species and a new synonymy in the genus Doliops Waterhouse, 1841 (Coleoptera: Cerambycidae) from Philippines. Baltic J. Coleopterol., 17(2): 161 - 173. Four new species of the genus Doliops Waterhouse, 1841 (Coleoptera: Cerambycidae) from Philippines are described and illustrated: D. boteroi sp. n. (Mindanao), D. dunskisi sp. n. (Mindanao), D. mindoroensis sp. n. (Mindoro) and D. santossilvai sp. n. (Mindanao) One synonymy is proposed: D. duodecimpunctata Heller, 1923 = D. gutowskii Barševskis, 2013 syn. n. The genus Doliops in the world fauna is now represented by 57 species. Key words: Coleoptera, Cerambycidae, Doliops, fauna, new species, new synonymy, Philippines Arvīds Barševskis.
