Three new species of the genus Xizicus (Orthoptera: Tettigoniidae: Meconematinae) from Taiwan.

The paper reports three new species of the genus Xizicus Gorochov, 1993 (Orthoptera: Meconematini) from Taiwan, i.e. Xizicus (Eoxizicus) hsiehi sp.

Formation of the acrosome complex in the bush cricket Gampsocleis gratiosa (Orthoptera: Tettigoniidae).

The acrosome complex plays an indispensable role in the normal function of mature spermatozoa. However, the dynamic process of acrosome complex formation in insect remains poorly understood. Gampsocleis gratiosa Brunner von Wattenwyl possesses the typical characteristic of insect sperms, which is tractable in terms of size, and therefore was selected for the acrosome formation study in this report.

Three new species of the genus Xiphidiopsis Redtenbacher, 1891 (Orthoptera: Tettigoniidae: Meconematinae) in China.

The article reported three new species of the genus Xiphidiopsis Redtenbacher, 1891 in China: Xiphidiopsis (Xiphidiopsis) minorincisus Han, Chang & Shi sp. nov., Xiphidiopsis (Xiphidiopsis) protensus Han, Chang & Shi sp.

Notes on the genus Pseudokuzicus Gorochov, 1993 (Orthoptera: Tettigoniidae: Meconematinae: Meconematini) from China.

Two new species of the genus Pseudokuzicus are described: Pseudokuzicus (Pseudokuzicus) trianglus sp. nov. and Pseudokuzicus (Pseudokuzicus) platynus sp.

Notes on a collection of the tribe Meconematini (Orthoptera: Tettigoniidae) from Hainan, China.

This paper deals with 7 genera and 12 species of the tribe Meconematini from Hainan, China, three of which are new species, i.e. Xizicus (Axizicus) bispinus sp.

One new species of the genus Alloteratura Hebard, 1922 (Orthoptera: Tettigoniidae: Meconematinae) from Yunnan, China.

The paper describes one new species of the genus Alloteratura Hebard, 1922 from Yunnan, China, i.e. Alloteratura quaternispina, sp.

One new genus and two new species of the tribe Meconematini (Orthoptera: Tettigoniidae: Meconematinae) from Yunnan, China.

One new genus, Paraphlugiolopsis Bian & Shi gen. nov., and two new species, Paraphlugiolopsis jiangi Bian & Shi sp.

Second supplement for the genus Phlugiolopsis Zeuner, 1940 (Orthoptera: Tettigoniidae: Meconematinae) from China, with eight new species.

This paper deals with 8 new species of Phlugiolopsis from Yunnan and Guizhou, China, supplements the images of P ventralis Wang, Li & Liu, 2012 and details the morphology of male stridulatory files and mandibles for 9 Phlugiolopsis known species. Distribution of poorly known species and new species are presented. A key to all known species is provided.

Notes on a collection of Meconematinae (Orthoptera: Tettigoniidae) from Damingshan, Guangxi, China with the description of a new species.

This paper deals with 6 genera and 10 species of the tribe Meconematini from Damingshan, Guangxi, China, one of which is a new species, i.e. Xizicus (Eoxizicus) laminatus Shi sp.

A new genus and two new species of the tribe Meconematini (Orthoptera: Tettigoniidae) from China.

The study deals with one new genus and two new species, i. e. Allicyrtaspis gen.

The mitochondrial genome of the quiet-calling katydids, Xizicus fascipes (Orthoptera: Tettigoniidae: Meconematinae).

To help determine whether the typical arthropod arrangement was a synapomorphy for the whole Tettigoniidae, we sequenced the mitochondrial genome (mitogenome) of the quiet-calling katydids, Xizicus fascipes (Orthoptera: Tettigoniidae: Meconematinae). The 16,166-bp nucleotide sequences of X. fascipes mitogenome contains the typical gene content, gene order, base composition, and codon usage found in arthropod mitogenomes.

[Genetic differentiation among different geographic populations of Gampsocleis sedakovii].

The mitochondrial cytochrome oxidase I (mtDNA-COI) gene was used to investigate the intraspecific genetic subdivision among 12 geographical populations of Gampsocleis sedakovii distributed in Jilin, Liaoning, Inner Mongolia, Hebei, and Sichuan provinces, China. As for the 626 bp mtDNA-COI sequences of 36 individuals, 29 haplotypes and 71 (11.3%) polymorphic sites were detected, including 37 parsimony informative and 34 singleton variable sites.

[Chromosomal studies of three species of Tettigoniidae].

The karyotypes of three species belonging to three genera of Tettigoniidae were investigated. The diploid number of chromosomes for Tettigonia chinensis is 2n male = 31,for Gampsocleis obscura 2n male = 31,Atlanticus sinensis 2n male = 29. In the three species, the XO male/XX female type of sex determination was observed.
