Omophorus (Sinomophorus) wallaCei: a new weevil from Borneo highlights the enigmatic Ethiopian-Oriental disjunct distribution (Coleoptera, Curculionidae, Molytinae) Author Tseng, Wei-Zhe Author Hsiao, Yun Author Hsu, Chen-Fu text Zootaxa 2018 2018-06-22 4438 3 588 596 journal article 29815 10.11646/zootaxa.4438.3.10 50118f26-9f46-40da-9739-2ca57527370c 1175-5326 1298162 439C6BBB-393A-470C-9332-383351BFAD2A Subgenus Sinomophorus Wang, Alonso-Zarazaga, Ren & Zhang, 2011 Type species. Omophorus rongshu Wang, Alonso-Zarazaga, Ren & Zhang, 2011 : 44 . Diagnosis (modified based on Wang et al . (2011 )). Distinguished from nominal subgenus by the absence of tubercle on pronotal surface; bifid vestiture of the venter; the obtuse humeral angle; extremely small extent of sclerotization in the endophallus; absence of styli in the ovipositor and the absence of a spiculum ventrale on female sternite VIII. It can be separated from the subgenus Pangomophorus Voss, 1960 by the bifid vestiture of the venter; the obtuse humeral angle; and the presence of a metatibial uncus. Several diagnostic characters, including longer antennal club; elongate subtrapezoidal scutellum and smaller subhumeral calli, proposed in Wang et al. (2011) are considered invalid for a new subgeneric delimitation on the basis of the comparison between O. ( S. ) rongshu and O. ( S. ) wallacei (see details in discussion).
