Two new species of the genus Callimetopus Blanchard, 1853 (Coleoptera: Cerambycidae) from Palawan and Marinduque islands (Philippines). Baltic J. Coleopterol., 18(2): 291 – 296. Two new species of long-horned beetles of the genus Callimetopus Blanchard, 1853 from the Philippines are described and illustrated: C. bumbierisi sp. n. (Palawan) and C. marinduquensis sp. n. (Marinduque). The genus Callimetopus is now represented by 49 species. Key words: taxonomy, new species, long-horned beetles, Callimetopus, Lamiinae, Pteropliini, Philippines Arvīds Barševskis.
