On Some Species of the Leaf-Beetle Genera Colaspoides Laporte, 1833 and Colaspedusa L. Medvedev, 1998 (Coleoptera, Chrysomelidae: Eumolpinae)

Two new species of the subfamily Eumolpinae are described: Colaspoides patrikeevi sp. n. from China and Colaspedusa houaphanica sp. n. from Laos. The type series of Colaspoides pseudodiffinis L. Medvedev, 2004 is shown to include, in addition to this species, some specimens of C. paddis Aslam, 1968 and C. pallidicornis Tan et Zhou, 1997. The synonymy, variation, and distribution of species of this complex, and also of forms of the C. prasinus Lefèvre, 1890 complex (including the subspecies C. p. occidentalis L. Medvedev, 2004) are discussed. Colaspoides prasinus prasinus is recorded from China and Thailand for the first time. The habitus and genitalia are illustrated for most of the taxa considered.
