New and little-known species of Geinitziidae (Insecta: Grylloblattida) from the Middle Jurassic of China, with notes on taxonomy, habitus and habitat of these insects

Cui, Y., Storozhenko, S.Yu. & Ren, D., June 2012. New and little-known species of Geinitziidae (Insecta: Grylloblattida) from the Middle Jurassic of China, with notes on taxonomy, habitus and habitat of these insects. Alcheringa, 251–261. ISSN 0311-5518. A new species, Geinitzia aristovi sp. nov. (Grylloblattida: Geinitziidae) is described and illustrated from the Middle Jurassic Jiulongshan Formation near the Daohugou Village, Ningcheng County, Inner Mongolia, northeastern China. Megasepididontus Huang & Nel, 2008 (Middle Jurassic of China) is synonymized under Shurabia Martynov, 1937. Two new combinations are proposed: Megasepididontus grandis Huang & Nel, 2008 = Shurabia grandis (Huang & Nel, 2008) comb. nov. and Shurabia shartegica Aristov, Wappler & Rasnitsyn, 2009 = Sinosepididontus shartegicus (Aristov, Wappler & Rasnitsyn, 2009), comb. nov. Shurabia grandis (Huang & Nel, 2008) and Sinosepididontus chifengensis Huang & Nel, 2008 are re-described and illustrated based on new materials from the type locality. A key to the genera of Geinitziidae is constructed. The diagnosis of Geinitziidae is emended by the body characters exhibited in the new fossils. A suite of morphological characters suggest that the Geinitziidae were diurnal above-ground predators.

A New Genus of Pygmy Locusts (Orthoptera: Tetrigidae: Cladonotinae) from the Malay Peninsula

Abstract. The monotypic genus Hancockitettix Storozhenko et Pushkar, gen. nov. (type species Hancockitettix humeratus Storozhenko et Pushkar, sp. nov.) from the Malay Peninsula is described. A new genus belongs to the subfamily Cladonotinae. It resembles the genera Hancockella Uvarov, 1940 from India and Austrohancockia Günther, 1938 from China, Taiwan, Japan and Vietnam in the general body appearance, in the large lobules on the upper and lower margins of the fore and mid femora, and in the relatively narrow scutellum, but differs from them by the presence of fully developed tegmen, hind wing and tegminal sinus, by the triangular plate-like projected shoulder of pronotum, and by the considerable distance between the most outstanding parts of shoulders which exceeds the pronotum lobe width (in other mentioned genera the hind wing and tegminal sinus are absent, the tegmen is absent or rudimentary, lateral side of shoulder is broadly rounded or obtusely angular, and the distance between shoulders is less than the pronotum lobe width).

New and little-known pygmy grasshoppers (Orthoptera: Tetrigidae) from Thailand

An annotated list of 39 species in 25 genera and seven subfamilies of the pygmy grasshoppers (Orthoptera: Tetrididae) from Thailand is given; from these 18 species are recorded from this country for the first time. Five new species are described: Cotysoides gaponi sp. nov. (subfamily Metrodorinae), Eucriotettix anisyutkini sp. nov., Gavialidium bufocrocodil sp. nov., Scelimena bellula sp. nov. (subfamily Scelimeninae) and Phaesticus uvarovi sp. nov. (subfamily Discotettiginae). One species is transferred from Scelimena to Amphibotettix and a new combination is proposed: Scelimena hafizhaii Mahmmod, Idris et Salman, 2007 = Amphibotettix hafizhaii (Mahmmod, Idris et Salman, 2007), comb. nov. The previously unknown male of Falconius tschernovi Storozhenko, 2014 is described.

Integrative taxonomy reveals two sympatric species of the genus Eucriotettix Hebard, 1930 (Orthoptera: Tetrigidae)

Limno-terrestrial pygmy grasshoppers are mostly recognised using morphology but characters used are not always clear-cut for species identification. From a faunistic survey in Singapore, Eucriotettix were collected and two new species are identified and described here: E. guentheri sp. nov. and E. simulans sp. nov. This was done by iteratively incorporating morphological, molecular, morphometric, and ecological data. Mitochondrial COI trees, COI cluster analysis, microhabitat preference, and morphometric analyses provide strong enough indirect evidence that the specimens comprise a pair of species. A key to species of Eucriotettix from Singapore is also provided.

A New Genus of Pygmy Locusts (Orthoptera: Tetrigidae: Metrodorinae) from Vietnam

Abstract The monotypiC genus Gorochovitettix Storozhenko et Pushkar, gen. nov. (type species Gorochovitettix kannackiensis Storozhenko et Pushkar, sp. nov. from Vietnam) is described in the subfamily Metrodorinae. The new genus is similar to the genus Orthotettix Hancock, 1909 from Malaysia, differing from the latter by the fore and mid femora considerably compressed laterally with the leaf-like upper and lower carinae. The new genus is similar to the genera Vaotettix Podgornaja, 1986 from Vietnam and Paramphinotus Zheng in Zheng and Ou, 2004 from South China by the distinctly widened frontal ridge, differing from them by the antennal socket placed distinctly below the lower margin of eye.

Three new species of the subfamily Cladonotinae (Orthoptera: Tetrigidae) from Thailand

The pygmy grasshopper subfamily Cladonotinae and genera Epitettix Hancock, 1907, Pseudepitettix Zheng, 1995 and Tuberfemurus Zheng, 1992 are firstly recorded from Thailand. Three new species, namely Epitettixobtusus obtusus sp. nov. from provinces Nakhon Ratchasima and Chiang Mai, Pseudepitettix pimkarnae sp. nov. from province Saraburi and Tuberfemurus kanokwanae sp. nov. from province Saraburi, are described.

Pygmy grasshoppers (Orthoptera: Tetrigidae) of Vietnam: the genus Bolivaritettix Günther, 1939

Vietnamese species of the genus Bolivaritettix Günther, 1939 are reviewed and illustrated. Altogether ten species are reported from Vietnam, of which five are new to science, namely-B. abruptus sp. nov., B. anaglypticus sp. nov., B. constrictus sp. nov., B. similis sp. nov., and B. vietnamensis sp. nov., while three species, B. sculptus (Bolívar, 1887), B. humeralis Günther, 1939 and B. celaenotus Zheng, Zhang et Dang, 2009, are recorded from Vietnam for the first time. A key to Vietnamese species is provided.

A new species of the genus Mesambria Stål, 1878 with notes on the tribe Mesambriini (Orthoptera: Acrididae, Catantopinae)

The new species Mesambria intermedia Storozhenko, sp. nov. is described from Indonesia. Male genitalia of the type species of the genera Mesambria Stål, 1878 and Traulia Stål, 1873 are described and illustrated for the first time. The diagnosis of the tribe Mesambriini is given and the position of this tribe in the modern classification of grasshoppers is discussed. New synonymy is proposed: Mesambriini Brunner von Wattenwyl, 1893 = Trauliini Bolivar, 1917, syn. nov., = Ranacridinae Xia, 2006, syn. nov.

Revision of the genus Angaracris Bey-Bienko, 1930 (Orthoptera: Acrididae, Oedipodinae) with notes on the tribe Bryodemini

Anagaracris is considered as a monotypic genus in the tribe Bryodemini (Acrididae: Oedipodinae). New synonymy is proposed: Angaracris barabensis (Pallas, 1773) = Angaracris morulimarginis Huang, 1981, syn. nov.; = Angaracris ulashanicus Li, 1981, syn. nov.; Angaracris acrohylina Bi, 1986, syn. nov.; = Angaracris nigrimarginis Zheng et Ren, 1993, syn. nov.; = Angaracris morulipennis Zheng et Ren, 1994, syn. nov.; = Angaracris neimongolensis Zeng et Han, 1998, syn. nov. The diagnosis of the tribe Bryodemini is clarified and a key to the genera and subgenera is provided.

A new species in the genus Alectorolophus Brunner von Wattenwyl, 1898 from Indonesia with discussion on its position compared to allied genera in subfamily Catantopinae (Orthoptera: Acrididae).

Alectorolophus impunctus Storozhenko et Kim, sp. nov. from Sulawesi Island, Indonesia, is described here. Keys to both sexes of all known species and subspecies of Alectorolophus are also provided in this report. The position of genus Alectorolophus in the systematics of grasshoppers is clarified. It belongs to subtribe Ecphantina (Catantopinae: Catantopini) consisting of nine genera distributed in Australia and Oriental regions. The diagnosis of Ecphantina is clarified and a key to genera is provided. An annotated list of the genera and species of Ecphantina is given. Moreover, the correct name of the subfamily Coptacridinae is Coptacrinae Brunner von Wattenwyl, 1893.
