Characters of the tetrigid genus Alulatettix Liang are redescribed. Three new species, Alulatettix nigromarginalis n. sp., Alulatettix flavotibialis n. sp., and Alulatettix tianzhushanensis n. sp., are described. An updated key to the species of this genus is provided.
The taxonomy of the tetrigid genus Alulatettix Liang is reviewed. A new species, Alulatettix orthomarginalis n. sp. is described. The annotated list and key to all known species of Alulatettix are given.
In this talk, we review our recent work about the dynamical studies of Z + (4430) and X(3872). Z + (4430) can not be explained as a D ′ 1 D * or D 1 D * molecular state only considering one pion exchange potential without the cutoff, which needs to be confirmed by introducing sigma exchange potential and adding the cutoff in the effective potential. One… (More)
Two new species of the tetrigid genus Criotettix Bolivar from China, namely Criotettix interruptaoides Deng & Zheng n. sp. and Criotettix shiwanshanensis Deng & Zheng n. sp. are described. An updated key to all known species of the genus from China is given.
Four new species of Tetrigidae (Orthoptera) from Anhui province, China, are described, namely Paragavialidium anhuiensis n. sp. of Scelimeninae, Bolivaritettix jinzhaiensis n. sp. of Metrodorinae, Bannatettix anhuiensis n. sp., and Formosatettix albomaculatus n. sp. of Tetriginae.
Two new species of the tetrigid genus Xistra Bolivar from China, namely Xistra oculata Li, Deng et Zheng n. sp. and Xistra brachynota Li, Deng et Zheng n. sp. are described. An updated key to all known species of the genus is given.
We propose an extended Nambu–Jona-Lasinio model to include the heavy mesons with the heavy quark symmetry. The quark current-current interaction is generalized to include the heavy quark currents. In order to comply with the heavy quark spin symmetry at the heavy quark limit, the quark mass dependence of the interaction strength is introduced. The light and… (More)
The genus Eucriotettix Hebard from China was reviewed and 13 were species recorded, including two new species: Eucriotettix nigripennis Deng & Zheng n. sp. and Eucriotettix strictivertex Deng & Zheng n. sp. A key to the species of Eucriotettix from China is provided. Type specimens were deposited in the Institute of Zoology, Shaanxi Normal University.
