Mitochondrial Genomes of Three Tetrigoidea Species and Phylogeny of Tetrigoidea
Mitochondrial genomes of three Tetrigoidea species and phylogeny of Tetrigoidea Li-Liang Lin1, Xue-Juan Li1, Hong-Li Zhang2 and Zhe-Min Zheng1 1 College of Life Sciences, Shaanxi Normal University, Xi'an, Shaanxi, China 2 School of Life Sciences, Datong University, Datong, Shanxi, China ABSTRACT The mitochondrial genomes (mitogenomes) of Formosatettix qinlingensis, Coptotettix longjiangensis and Thoradonta obtusilobata (Orthoptera: Caelifera: Tetrigoidea) were sequenced in this study, and almost the entire mitogenomes of these species were determined. The mitogenome sequences obtained for the three species were 15,180, 14,495 and 14,538 bp in length, respectively, and each sequence included 13 protein- coding genes (PCGs), partial sequences of rRNA genes (rRNAs), tRNA genes (tRNAs) and a A C T-rich region. The order and orientation of the gene arrangement pattern were identical to that of most Tetrigoidea species. Some conserved spacer sequences between trnS(UCN) and nad1 were useful to identify Tetrigoidea and Acridoidea. The Ka/Ks value of atp8 between Trachytettix bufo and other four Tetrigoidea species indicated that some varied sites in this gene might be related with the evolution of T. bufo. The three Tetrigoidea species were compared with other Caelifera. At the superfamily level, conserved sequences were observed in intergenic spacers, which can be used for superfamily level identification between Tetrigoidea and Acridoidea. Furthermore, a phylogenomic analysis was conducted based on the concatenated data sets from mitogenome sequences of 24 species of Orthoptera in the superorders Caelifera and Ensifera. Both maximum likelihood and bayesian inference analyses strongly supported Acridoidea and Tetrigoidea as forming monophyletic groups. The relationships among six Tetrigoidea species were (((((Tetrix japonica, Alulatettix Submitted 9 May 2017 yunnanensis), Formosatettix qinlingensis), Coptotettix longjiangensis), Trachytettix bufo), Accepted 17 October 2017 Thoradonta obtusilobata). -
(Orthoptera) and Their Phylogenetic Implications Within Tetrigoidea
Mitochondrial genomes of eight Scelimeninae species (Orthoptera) and their phylogenetic implications within Tetrigoidea Ran Li1, Xiaoli Ying1, Weian Deng2, Wantao Rong2 and Xiaodong Li2 1 College of Life Sciences, Nanjing Normal University, Nanjing, China 2 School of Chemistry and Bioengineering, Hechi University, Yizhou, China ABSTRACT Scelimeninae is a key member of the pygmy grasshopper community, and an important ecological indicator. No mitochondrial genomes of Scelimeninae have been reported to date, and the monophyly of Scelimeninae and its phylogenetic relationship within Tetrigidae is still unclear. We sequenced and analyzed eight nearly complete mitochondrial genomes representing eight genera of Scelimeninae. These mitogenomes ranged in size from 13,112 to 16,380 bp and the order of tRNA genes between COII and ATP8 was reversed compared with the ancestral order of insects. The protein-coding genes (PCGs) of tetrigid species mainly with the typical ATN codons and most terminated with complete (TAA or TAG) stop codons. Analyses of pairwise genetic distances showed that ATP8 was the least conserved gene within Tetrigidae, while COI was the most conserved. The longest intergenic spacer (IGS) region in the mitogenomes was always found between tRNASer(UCN) and ND1. Additionally, tandem repeat units were identified in the longest IGS of three mitogenomes. Maximum likelihood (ML) and Bayesian Inference (BI) analyses based on the two datasets supported the monophyly of Tetriginae. Scelimeninae was classified as a non-monophyletic subfamily. -

The Cytology of Tasmanian Short-Horned Grasshoppers ( Orthoptera: Acridoidea)
PAP. & PROC. ROY. Soc. TASMANIA. VOL. 86. (15TH SEPTEMBER. 1952.) The Cytology of Tasmanian Short-Horned Grasshoppers ( Orthoptera: Acridoidea) By G. B. SHARMAN Department of Botany, University of Tasmania* WITH 1 PLATE AND 57 TEXT FIGURES SUMMARY The cytology of twenty-six of the twenty-nine species of short-horned grass hoppers (superfamily Acridoidea) recorded from Tasmania is described. Intra specific cytological polymorphism is described in some species. Cytological evidence of phylogenetic relationships has been indicated where possible. INTRODUCTION Mainly because of their large size, and general suitability for cyto logical study the chromosomes of the short-horned grasshoppers (super family Acridoidea) have been the subject of wide research. In the largest and most widely studied family, the Acrididae, early workers (McClung, 1905; Davis, 1908) reported the male number as being uniformly twenty three rod-shaped chromosomes, but Granata (1910) showed that Pam phagus possessed nineteen rod-shaped chromosomes. With few exceptions an XO sex chromosome sy~tem is found. Later work has shown that one group of subfamilies of the Acrididae is characterised by the male diploid number of· nineteen rod-shaped chromosomes, whilst another and larger group is characterised by the male diploid number of twenty-three. These are usually called the ten and twelve chromosome groups, and correspond to the Chasmosacci and Cryptosacci groups of subfamilies (Roberts, 1941). Cytologically the Chasmosacci is a very uniform group as has been shown by Rao (1937) and Powers (1942). The twelve chromosome group, how ever, has some cytological variability. In more than forty genera the characteristic male diploid chromosome number of twenty-three is found (White, 1945) ; but" centric fusions" (White, 1945) have been responsible for lowering the chromosome number of some species, although the characteristic twenty-three arms are still found. -

Based on detailed examinations of museum specimens and high-resolution digital images, we have produced an illustrated key to 21 Pyrgomorphidae genera known from the Indian subcontinent. This new identification key will become a useful tool for increasing our knowledge on the taxonomy of grasshoppers in this important biogeographic region. Key words: dichotomous key, gaudy grasshoppers, taxonomy Introduction The Indian subcontinent is known to harbor a high level of insect biodiversity and endemism (Ghosh 1996), but is also one of the most poorly studied regions in terms of biodiversity discovery (Song 2010). -

Zoological Studies 51(1): 51-58. A dietary analysis is a frequent 1st step in studying an animal’s ecology, because its diet directly reflects resource use and can provide insights into habitat utilization and competitive interactions. Little is known concerning orthopteran species that inhabit moist or wet environments, because such species do not usually become pests. We hypothesized that aquatic orthopterans feed on only a few macrophytes, and they show trophic niche overlap. Feeding habits of 7 orthopteran species associated with macrophytes, the botanical composition of the diets of these insects, and their trophic niche breadth and overlap were analyzed from the Middle Paraná River, Argentina. The diet composition by a microanalysis of feces under an optical microscope and the frequency of occurrence of each plant, food niche breadth, niche overlap, and food specialization level of every species were determined. Only Paulinia acuminata, Marellia remipes, and Cornops aquaticum exclusively consumed aquatic plants. The water hyacinth (Eichhornia crassipes) was the unique macrophyte consumed by all orthopteran species studied, although in different proportions. -

Invertebrates Recorded from the Northern
MARIANA ISLANDS BIODIVERSITY. Short-horn grasshoppers Phylum: Arthropoda Class: Insecta Order: Orthoptera Suborder: Caelifera Superfamilies: Tetrigoidea and Acridoidea. Diversity Micronesia – 23 species, Mariana Isl. – 10 species, CNMI - 9 species Ecological and human significance Short-horn grasshoppers are herbivores usually living in open grassy or weedy areas. Although they have been implicated in crop damage, such as maize, severe damage usually occurs only when there is a buildup of numbers, such as that occurring sometimes with the locust (Locusta migratoria). It is unlikely that any of the grasshoppers are indigenous to the Northern Mariana Islands as they are dwellers of open grassland or of, at least, low-cover, open areas. It is probable that most of the islands were mostly covered by forest prior to the advent and influence of man. It does seem that Stenocatantops splendens has recently entered the Northern Marianas, as , although it is now common on Saipan, there were no records prior to the recent (2000) collected material. It is a moderately sized animal and unlikely to be missed by collectors. Heteropternis obscurella seems, similarly, to have recently colonised the CNMI although its presence on Sarigan indicates a longer occupation period. Both species are in the University of Guam collection but were not recorded by Kevan et al 1997 from the Marianas. Conservation There are no conservation issues recognised at present, and none can really be determined until a thorough survey of the areas has been undertaken. All remaining natural habitats need to be conserved as much as possible. Identification There are no keys for in house identification, specimens have been sent (2002) to Dr. -
Acridoidea and Related Orthoptera (Grasshoppers) of Micronesia
Micronesica 30(1): 127-168, 1997 Acridoidea and Related Orthoptera (Grasshoppers) of Micronesia D. KEITH McE. KEvAN, VERNON R. VICKERY 1 AND MARY-LYNN ENGLISH Lyman Entomological Museum and Department of Entomology, McGill University, Macdonald Campus, 21111 Lakeshore Road, Ste-Anne-de-Bellevue, QC, Canada, H9X 3V9. Abstract-The species of grasshoppers of the superfamilies Acridoidea, Tetrigoidea, and Tridactyloidea of Micronesia are discussed with com plete data on Micronesian distribution. Two new species of Tetrigidae, Carolinotettix palauensis and Hydrotettix carolinensis, are described. Introduction Preliminary studies towards this contribution to our knowledge of the or thopteroid fauna of Micronesia are in an unpublished thesis by the third author (English 1978). Over the years, a considerable amount of additional information has been accumulated and two relevant papers published by the first author. In ad dition, there is a paper by the first author, in press, that deals with non-saltatorial orthopteroids. The first of the above publications (Kevan 1987) gives a preliminary survey of virtually all of the saltatorial orthopteroids (grigs) known to occur in Micronesia, as well as defining the limits of the region and giving a brief review of the relevant literature on the insects concerned. It also discusses some important points relating to the nomenclature of some of them. The second publication (Kevan 1990) is concerned with the same groups of insects, but confines its attention, more or less, to known or suspected introduced species (including Acridoidea) and their probable origins. A few non-saltatorial or thopteroids are also mentioned in passing. 2 Another paper (Kevan unpublished ) deals very fully with all groups of or thopteroids other than members of the saltatorial orders (termites and earwigs in cluded), mainly as recorded in the literature, which is extensively reviewed. -

Many of these caves are home to federally endangered invertebrates (USFWS 1988, 1993, 2000) or closely related, often rare taxa (Reddell 2001, Reddell and Cokendolpher 2001a). The majority of these caves are small – at Fort Hood (Bell and Coryell counties), the mean length1 of the caves is 51.7 m (range 2.1 - 2571.6 m, n=105 caves). Few of the caves harbor large numbers of bats, perhaps because low ceiling heights increase their vulnerability to depredation by other vertebrate predators (e.g., raccoons, Procyon lotor).
