Discussion. Besides L. humeralis. three other species are included in Lydipta Thomson, 1868: L. pumilio Thomson, 1868, type species; L. conspersa \ (Aurivillius, 1922) and L. senicula (Bates, 1865). I Lydipta humeralis is immediately distinguished by -< ' the tubercle on the humeral carina which is absent 1 2 in the other species. From L. sen.icula, an Amazo­ nian species, L. humeralis can be separated by the yellowish pubescence on the antennal scape with Figures 1-2: L Cocostola obliquata, sp. n., holotype male. few intermixed brown areas and by the sparser 2.
