“…ey are geographically close. Moussi et al (2018) stated that there was a match between the molecular and morphological classifications of many Oedipodinae species; however, Sphingonotus remained a problematic taxon in their phylogenetic analysis. ese authors interpreted this result as showing that COI-based species delimitation remains difficult, at least for most Sphingonotini genera, perhaps because of nuclear copies of mitochondrial sequences (pseudogenes), even though DNA barcoding is a valuable tool for identifying species in these genera.…”

“…eir findings illustrated that 1) external morphological characters are oen unreliable when drawing conclusions about taxonomic relationships and 2) genetic data, such as DNA sequences, are more useful when defining higher-level taxonomic groups. Using the mitochondrial cytochrome oxidase I (COI) gene, Moussi et al (2018) found that DNA barcoding is a valuable tool for identifying and delimiting species in many Oedipodinae genera. At present, COI-based barcoding is the most widespread method.…”

The Oedipodinae subfamily is the most species-rich and numerically abundant group of Acrididae in Algeria. Here, genetic and chemical data were used to characterize the identities of six species: Oedipoda miniata mauritanica (Lucas, 1849); Acrotylus patruelis (Herrich-Shaeffer, 1838); A. insubricus insubricus (Scopoli, 1786); Sphingonotus (Neosphingonotus) azurescens (Rambur, 1838); Sphingonotus (Neosphingonotus) finotianus (Saussure, 1885); and Sphingoderus carinatus (Saussure, 1888). Individuals were collected from two different sites in the Sétif region of northeastern Algeria. First, specimens were classified based on their morphological traits. Second, phylogenetic analysis was performed using DNA barcoding data (COI gene). Third, the specimens’ cuticular hydrocarbons (CHCs) were analyzed. The phylogenetic analysis revealed clear distinctions among the species. The chemotaxonomic analysis highlighted CHC profile similarities between S. azurescens and S. finotianus and CHC profile differences between A. patruelis and A. i. insubricus. Compared to S. azurescens and S. finotianus, S. carinatus had n-alkanes and trimethylalkanes with much shorter carbon chains. The genetic and chemical data obtained here have helped clarify differences within and between genera. These data also enabled to clearly distinguish among the six species.

Checklist and taxonomic updates in grasshoppers (Orthoptera: Caelifera) of central and southwestern Tunisia with new records and a key for species identification

Since the publication of Chopard's 1943 book, Les Orthoptéroides d'Afrique du Nord, the diversity of Orthoptera in Tunisia has not been studied or prospected except for 20 publications. Furthermore, the classification of Orthoptera has changed since 1943 due to taxonomic and phylogenetic advances. To allow a full survey of the Tunisian grasshopper fauna, it is thus necessary first to correctly survey the biological diversity of grasshoppers in Tunisia, and second to have an updated taxonomic reference in order to describe this diversity and compare it with the grasshopper faunas in the other countries of the Maghreb. In the present paper, we propose an updated checklist and a key for the identification of Tunisian grasshoppers, based primarily on field sampling in central and southwestern Tunisia, and literature data for other Tunisian areas. Each species is documented with habitus photographs, geographical distribution, and type of habitat. In total, for the prospected areas, 75 species of Caelifera belonging to five families and 43 genera are listed, while 83 species were recorded up to now for the whole Tunisia. Among these 75 species, seven are newly recorded for Tunisia, i.e., Sphodromerus

“…This species belongs to the oriental lineage of Sphingonotus , represents the adaptive status of Sphingonotus spp. in the East, and may serve as an ideal model for studying the evolution and ecology of grasshoppers in arid environments ( Husemann et al, 2014 ; Moussi et al, 2018 ). Nonetheless, only few studies and sequences of respective functional genes of this species are available ( Cui and Huang, 2012 ; Shah et al, 2019 ).…”

Sphingonotus Fieber, 1852 (Orthoptera: Acrididae), is a grasshopper genus comprising approximately 170 species, all of which prefer dry environments such as deserts, steppes, and stony benchlands. In this study, we aimed to examine the adaptation of grasshopper species to arid environments. The genome size of Sphingonotus tsinlingensis was estimated using flow cytometry, and the first high-quality full-length transcriptome of this species was produced. The genome size of S. tsinlingensis is approximately 12.8 Gb. Based on 146.98 Gb of PacBio sequencing data, 221.47 Mb full-length transcripts were assembled. Among these, 88,693 non-redundant isoforms were identified with an N50 value of 2,726 bp, which was markedly longer than previous grasshopper transcriptome assemblies. In total, 48,502 protein-coding sequences were identified, and 37,569 were annotated using public gene function databases. Moreover, 36,488 simple tandem repeats, 12,765 long non-coding RNAs, and 414 transcription factors were identified. According to gene functions, 61 cytochrome P450 (CYP450) and 66 heat shock protein (HSP) genes, which may be associated with drought adaptation of S. tsinlingensis, were identified. We compared the transcriptomes of S. tsinlingensis and two other grasshopper species which were less tolerant to drought, namely Mongolotettix japonicus and Gomphocerus licenti. We observed the expression of CYP450 and HSP genes in S. tsinlingensis were higher. We produced the first full-length transcriptome of a Sphingonotus species that has an ultra-large genome. The assembly characteristics were better than those of all known grasshopper transcriptomes. This full-length transcriptome may thus be used to understand the genetic background and evolution of grasshoppers.
