--A new species and a key to 10 species of the genus Lemba Huang, 1983 (Orthoptera: Catantopidae) from China.

A new species and a key to 10 species of the genus Lemba Huang, 1983, namely Lemba wushanensis sp. nov. is described in this paper from China. The new species is similar to L. sichuanensis Ma et al, 1994, but differs from the latter by the length of tegmen 2.7 times width in male, length of interspace of mesosternum 3.5 times width in male, posterior margin of epiproct straight; ancorae of epiphallus not inward tilt and vertical diameter 1.8 times subocular furrow in female. The type specimens are deposited in the Northwest Plateau Institute of Biology, Chinese Academy of Sciences, Xining, China.

Comparative analysis of mitogenomes among three species of Haplotropidini grasshoppers and a new species of the genus Sulcotropis (Orthoptera: Acridoidea: Pamphagidae) from China.

The complete mitochondrial genomes of three species of Haplotropidini were sequenced, annotated and analyzed. Then, combined with 18 species mitogenomes of Acridoidea and 1 species of Tridactyloidea, the phylogenetic relationships were reconstructed by maximum likelihood (ML) and Bayesian (BI) methods based on PCGs. The phylogenetic relationship tree showing that Sulcotropis Yin et Chou is a valid genus and not a synonym of Haplotropis Saussure, 1888. A new species Sulcotropis xiaowutaiensis sp. nov. is described in this paper from China, it is allied to Sulcotropis cyanipes Yin et Chou, 1979, but differs from latter by median carina of pronotum cut by posterior transverse sulcus slightly, epiphallus with middle part equal both sides in high, cercus of male gradually widened at base, interspace of mesosternum narrowed in the base slightly and subgenital plate of female oblong, hind margin with small acute angle in the middle. Type specimens are deposited in the College of Life Sciences, Hebei University, Baoding, Hebei, China.

A new species of the genus Tagasta Bolivar, 1905 (Orthoptera: Pyrgomorphidae) from India.

Tagasta mizoramensis sp. nov. is described from Dampa Wildlife Sanctuary, Mizoram, India. The type specimens are deposited in the Central Entomological Laboratory, Zoological survey of India.

A new species of the genus Sinohaplotropis Cao et Yin, 2008 (Orthoptera, Acridoidea, Pamphagidae) from Amur River, Russia.

The genus Sinohaplotropis Cao et Yin, 2008 is a valid genus and not a synonym of Haplotropis Saussur, 1888. A new species Sinohaplotropis amurensis sp. nov. is described in this paper from Russia. The new species is similar to Sinohaplotropis erenchuanensis Cao et Yin, 2008, but differs from latter by subgenital plate of male triangular, with large bifurcate apex in dorsal view, pronotum longer reaching first abdominal tergite, top of Kraus` organ narrow and interspace of mesosternum straight in the middle. Type specimen is deposited in the Hebei University, Baoding, Hebei, China.

A new species of the genus Xya Latreille, 1809 from Shandong, China (Orthoptra, Tridctyloidea, Tridactylidae).

The genus Xya Latreille, 1808 obtains 56 known species in the world, among them 20 species distributed in Asia and 7 species in China only i.e. Xya japonica (Haan, 1842); Xya nitobei (Shiraki, 1911); Xya manchurei Shiraki, 1936; Xya apicicornis (Chopard, 1928); Xya riparia (Saussure, 1877); Xya leshanensis Cao et al, 2017 and Xya sichuanensis Cao et al, 2018, [Haan, 1844; Walker, 1871; Saussure, 1877, 1896; Brunner von Wattenwyl. 1893; Bolivar, 1900(1899); Shiraki, 1911, 1936; Chopard, 1928, 1936, 1968; Bey-Bienko, 1967; Günther, 1974. 1980; Ingrisch, 1987; Yin et al, 1996; Murai, 2005; Yin et al, 2013; Heads Hollier, 2016; Kuravova Kocarek, 2016; Zhang et al, 2017; Cao et al, 2017; Cao et al, 2018; Cigliano et al, 2018]. In the present paper, we describe a new species of the genus from Junan county, Shandong province, China. The new species Xya shandongensis sp. nov. is similar to Xya japonica (Haan, 1842), but differs from latter by antennae near moniliform, length of segment 1.2 times maximum width, median and lateral ocelli placed median part of eyes, pronotum with larger yellow stripe on hind apical part of both sides, hind femur black, upper side with a yellowish-white spot at the base of 1/3 place, hind wing long, reaching the base of epiproct. Type specimens are deposited in the College of Plant Protection, Shandong Agricultural University, Taian, Shandong 271018, China.
