The Genus Cneorane Baly, 1865 from Taiwan (Coleoptera: Chrysomelidae: Galerucinae), with Notes on Sexual Dimorphism and Its Life History

並列摘要


Background: Three species of the genus Cneorane Baly, 1865 are recorded originally from Taiwan: C. femoralis Jacoby, 1888, C. rugulipennis (Baly, 1886), and C. violaceipennis Allard, 1889.Results: The result indicates that C. elegans Baly, 1874 (= C. rufipes Weise, 1889, syn. nov. and C. cyanipennis Chûjô, 1938, syn. nov.), C. violaceipennis Allard, 1889 (= C. fokiensis Weise, 1922, syn. nov.), and C. rugulipennis Baly, 1886 (= C. femoralis Jacoby, 1888, syn. nov. and C. formosana Weise, 1922) are recognized. Cneorane violaceipennis, misidentified as C. elegans for more than 100 years, is redefined and recorded from Taiwan for the first time. Sexually dimorphic characters and diagnostic ones for each species are addressed. The life histories of Cneorane species are noted. Lectotypes are designated for C. violaceipennis Allard, 1889, C. femoralis Jacoby, 1888, and C. cyanipennis Chûjô, 1938.Conclusions: The present state of taxonomic study on this genus is insufficient. However, it can be improved if variable characters are detected and sexually dimorphic characters are found by examining sufficient material.
