Authors analysed 33 supraspecific taxa of Palaearctic Platycleidini with unarmed prosternum, most of them hitherto considered genera or subgenera of Platycleis and Metrioptera. For each of them they give a short description of the characters revealing the correct classification of males and females. Then, they propose a more consistent classification, when both males and females of a supraspeci...

Based on specimens in various museum collections one new subgenus and six new species of Elimaeini are described: Poaefoliana subgen. n. (type species Locusta poaefolia De Haan, 1842) of Elimaea Stål, 1874; Elimaea (Poaefoliana) albimaculata sp. n., E. (P.) jitra sp. n., E. (P.) kutu sp. n., Elimaea (Schizelimaea) singgalang sp. n., Orthelimaea kanburi sp. n., O. volsella sp. n. Three classical...

Macroptery is common in many species of Orthoptera, but the causes are still discussed. Besides the assumption that macroptery is genetically determined, there is evidence that wing dimorphism is induced by environmental factors, particularly population density. However, most of the research is on pest species. In contrast, knowledge of wing dimorphism in species that occur at low population de...

The following new taxa of Meconematini from Guangxi province were described: Sinothaumaspis damingshanicus Wang, Liu, Li gen. & sp. nov., Aphlugiolopsis punctipennis Wang, Liu, Li gen. & sp. nov., Eoxizicus (Eoxizicus) curvicercus Wang, Liu, Li sp. nov., Meconemopsis paraquadrinotata Wang, Liu, Li sp. nov., Neocrytopsis? unicolor Wang, Liu, Li sp. nov., Xiphidiopsis (Dinoxiphidiopsis) expressa ...
