A new subgenus of the genus Chrysolina Motschulsky, 1860, endemic to Yunnan Province China, Ch. (Volosatik subgen. nov.) is described. All species inhabit highland forests. Seven species, including four science, are recognized: fascinatrix Lopatin, 1998, liqingzhaoae Daccordi et Ge, 2011, wangi 2005, igori sp. nov., marinae genriki and ilyakabaki nov. The representatives this characterised by a...

1. Pulling forces of Chrysolina polita (L.) on glass, perspex and cloth have been recorded and are plotted against body weight. The additional weight of eggs in many of the females is probably the main reason that, in females, pulling forces do. not increase significantly with body weight, whereas those of males do. 2. Pulling forces on glass and perspex are significantly correlated but, in gen...

Abstract The monophyletic status of the genus Oreina as well its phylogenetic relation to closely related genera Chrysolina , Crosita and Cyrtonus has been debated for several decades. To assess understand evolutionary history, we performed a museomics study on 148 museum specimens belonging 25 28 described species 19 other chrysomelid species, mainly from . Using innovative molecular methods r...
