The molecular hypothesis on relationships of Metanoeina lineages is presented and results are compared with morphology. A new genus Ochinoeus is proposed for four East Palearctic and Oriental species. Ochinoeus is recovered as a sister lineage to Matsudanoeus Sklenarova et al., 2014 and differs from related genera in morphology of genitalia and incomplete secondary elytral costae. We show, that the structure of elytral costae, although highly homoplastic across Metriorrhynchini, can be used for identification of Ochinoeus. The geographic distribution of Metanoeina is limited to the eastern parts of the Palaearctic and Oriental regions. The reconstruction of ancestral ranges identifies continental Eastern Asia as the centre of generic diversity of Metanoeina and suggests the dispersal from continental Asia to the southern part of the Oriental region, i.e. to the Sundaland and Philippines. Among Metanoeina lineages, only Metanoeus Waterhouse, 1878 contains higher number of species. The following four species are described: Ochinoeus huaphanensis sp. nov., O. hainanensis sp. nov., O. habashanensis sp. nov., and O. xunyanbaensis sp. nov..
提出了关于Metanoeina谱系关系的分子假说,并将结果与形态学进行了比较。为四个东古北区和东洋区的物种建立了一个新属Ochinoeus。Ochinoeus被认为是Matsudanoeus Sklenarova等人(2014年)的姐妹谱系,在生殖器形态和不完全的次生鞘翅肋方面与相关属不同。我们表明,鞘翅肋的结构虽然在Metriorrhynchini中具有高度同塑性,但可用于鉴定Ochinoeus。Metanoeina的地理分布仅限于古北区和东洋区的东部。祖先分布范围的重建确定东亚大陆是Metanoeina属多样性的中心,并表明从亚洲大陆扩散到东洋区的南部,即巽他群岛和菲律宾。在Metanoeina谱系中,只有1878年的Metanoeus Waterhouse包含较多的物种。描述了以下四个新物种:Ochinoeus huaphanensis sp. nov.、O. hainanensis sp. nov.、O. habashanensis sp. nov.和O. xunyanbaensis sp. nov.。
