RESUMO

A new species of the genus is described from Zhejiang, China in this paper. The new species Criotettix zhejiangensis sp. nov. is similar to Criotettix strivertexoides Zheng, Wei Li, 2009, but differs in antennae placed the lower margin of eye, head exserted above the pronotal surface, lateral keels in prozona slightly contracted backward, upper margin of pronotum not waved in lateral view, width of tegmen 1.2 times width of mid leg femur and lower side of hind femur not black. The new species is also similar to Criotettix strivertex Zheng, Wei Li, 2009, it differs from latter by head exserted above the pronotal surface, upper margin of pronotum not waved in lateral view, lower side of mid femur straight, width of tegmen 1.2 times width of mid leg femur and length of hind femur 3.1 times its width.

RESUMO

A new species of the genus Confusacris Yin Li, 1987, namely i.e. Confusacris shanxiensis sp. nov. is described in this paper from Shanxi province of China. The new species is similar to Confusacris brachypterus Yin Li, 1987 but differs from the latter by tegmen of male extending over middle of hind femur distinctly, maximum width of cubital vein area 1.5 times median vein area, furculae large, epiphallus without acute projection on both sides and length of interspace of mesosternum1.6 times minimum width in female.

RESUMO

Grasshoppers (Orthoptera: Acridoidea) are the main pests in agriculture, animal husbandry and forestry, and some species of grasshoppers can cause serious disaster. Taxonomy is the basis of pest control. Traditional morphological identification is time-consuming and laborious. It may be due to the existence of cryptic species or the limited number of morphologists, making the identification extremely unstable. In recent years, with the development of molecular systematics, DNA barcoding technology has been applied to environment, ecology, quarantine and so on. This study focuses on testing the feasibility of DNA barcoding in the species identification for superfamily Acridoidea. Sequences of the cox1 gene were obtained from 245 individuals of 43 species of Acridoidea and one species of Tetrigoidea as outgroup from Hebei Province. Phylogenetic, genetic distance and sequence difference threshold analyses using the Maximum Likelihood (ML), Automatic Barcode Gap Discovery (ABGD) and Molecular Defined Operational Taxonomic Units (MOTU) methods, respectively, were performed for obtained sequences and the 139 additional sequences of 21 species downloaded from GenBank. The results have shown that 40, 33, and 35 species among the 48 species are consistent with the traditional morphological classification based on the phylogenetic tree, ABGD and MOTU results, respectively and the DNA barcoding technology is very efficient and helpful for identifying the species of the superfamily Acridoidea; however, the morphological approach is still playing a key role in the species identifications. It also indicates that the cox1 gene is suitable for the phylogeny of genera and species level, but it is not suitable for the phylogenetic relationship of the advanced taxa such as families.

RESUMO

A new species (i.e. Bryodemella (s. str.) rufifemura sp. nov. from China is described in this paper. It is similar to Bryodemella (s. str.) diamesum (Bei-Bienko, 1930), but differs from the latter by red inner side of hind femur, median keel of pronotum indistinct in metazoan, and vertical diameter of eye shorter than subocular groove in female.  The type specimens are deposited in the Museum of Hebei University (MHU), China.

RESUMO

The complete mitochondrial genome of Sinotmethis brachypterus Zheng & Xi, 1985, which was collected from the Gansu Province of China, is reported here. It is 15,662 bp in length and contains 72.6% AT. All Sinotmethis brachypterus protein-coding sequences start with a typical ATN codon, excluding cox1 and nad6. The usual termination codon (TAN) and incomplete stop codons (T, TA) were found from 13 protein-coding genes. All tRNA genes could be folded into the typical cloverleaf secondary structure, excluding trnS(AGN) which forms another structure. The sizes of the large and small ribosomal RNA genes are 1320 and 852 bp, respectively. The AT content of the A + T-rich region is 84.2%.

RESUMO

Two new species i.e.: Humphaplotropis xiai sp. nov. and Humphaplotropis hebeiensis sp. nov. of the genus Humphaplotropis Xiao, Yin et Yin, 2013, are described from Hebei and Jiangsu, China in this paper. The new species Humphaplotropis xiai sp. nov. differs all known species of the genus by the abdomen like sawtooth in lateral view. The new species Humphaplotropis hebeiensis sp. nov. is similar to Humphaplotropis culaishanensis Lin, Cao et Yin, 2014, but differs from the latter by: lateral carinae of frontal ridge parallel; anterior margin of pronotum with acute angular in the middle, the apex reaching the hind margin of eyes; tegmina wider, cover 4/5 tympanum. Hind tibia yellow brown on upper side; epiphallus with 44 spikes, ancorae oblique inward distinctly, both posterior projections shorter than median projection. Type specimens are deposited in the Shanghai Entomological Museum, C.A.S., Shanghai and Natural Museum of Hebei University, Baoding, Hebei China respectively.

The new species Eotmethis platyverticus sp. nov. is allied to E. holanennis Zheng & Gow, 1981, but differs from latter by width of vertex between eyes 2 times diameter of eye and prozona of pronotum longer than metazoan in female. The type specimens are deposited in College of Life Sciences, Hebei University, Baoding, China.
