New subgenus and new species of Oriental Omophorus (Coleoptera, Curculionidae, Metatygini)

The genus Omophorus Schoenherr, 1835 is recorded for the first time from the Oriental Region, and a new subgenus and species, O. (Sinomophorus subgen. nov.) rongshu sp. nov. is described from Yunnan province (P.R. China). The new subgenus differs from subgenus Omophorus by the longer antennal club, the bifid vestiture of the ventral parts, the elongate subtrapezoidal scutellum, the very small size of sclerotizations in the endophallus, the absence of styli in the ovipositor and the absence of spiculum ventrale in the 8th female sternite, and from subgenus Pangomophorus Voss, 1960 by the metatibial uncus developed and the lack of subhumeral tubercle. A detailed description and figures are provided to allow interpretation of characters in ongoing phylogenetic analyses.
