Abstract:The following new species are described: Lydipta humeralis, sp. n. and obliquata, sp. n., from Ecuador; leuripennis, sp. n., and Carenesycha velezi, sp. it., from Colombia; Oltcideres marauara, sp. it., from Brazil (Amazonas). minuta Thomson, 1865, is recorded from Ecuador.

Key words: Coleoptera, Cerambycidae, Lamiinae, Onciderini

Discussion. Besides Z. humeralis, three other species are included in Lydipta Thomson, 1868: L. pumilio Thomson, 1868, type species; L. conspersa (Aurivillius, 1922) and Z. senicula (Bates, 1865). Zydipta humeralis is immediately distinguished by the tubercle on the humeral carina which is absent in the other species. From L. serricula, an Amazo- nian species, L. humeralis can be separated by the yellowish pubescence on the antennal scape with Figures 1-2: 1.
