Variations of density, diversity and biomass are analysed during three months (July, August and September). Density and diversity of Orthoptera are greater in meadows than in moors. Undergrove is appart. The place is compared to other sites in Limousin region., Annales Scientifiques du Limousin, HS | 1998

Les peuplements d’Orthoptéroïdes d’une lande sur serpentinite du Limousin sont décrits pour la première fois. 24 espèces ont été dénombrées, représentant environ 37 % de la faune limousine. Le milieu le plus riche en espèce est la pelouse à Festuca lemanii. La lande sèche à Ajonc nain a un peuplement conforme à celui des autres landes comparables sur sol siliceux en Limousin. Les associations s’intègrent majoritairement dans les synusies euryméditerranéennes et eurosibériennes. Les successions bien caractérisées de peuplements que l’on observe associés à la dynamique végétale peuvent servir de guide pour la gestion de ces milieux soumis à la déprise agricole., Orthopteroïd communities living on different plant associations settled on serpentinite formations are described for the first time. 24 species were recorded, representing about 37 % of the Limousin fauna. The richest milieu is the Festuca lemanii association. The dry heathland with dwarf gorse has the same community as in similar heathlands on siliceous soil in Limousin. Most insect communities belong to eurymediterranean and eurysiberian synusies. Well characterised successions of insect communities are closely associated to vegetation dynamics and constitute powerful tools to help in the management of these non-upkept habitats., Annales Scientifiques du Limousin, Tome 14 | 2003

Les auteurs analysent la dynamique végétale et les peuplements d’Orthoptères de la tourbière de la Crouzille (Monts d’Ambazac, Haute-Vienne). Les épaisseurs de tourbe sont mises en relation avec la végétation actuelle. Le fond tourbeux abrite une faune orthoptérique originale, les espèces les plus abondantes étant Chorthippus montanus et Conocephalus discolor. Au cours de l‘été, le milieu qui maintient le plus la diversité des Orthoptères est la cariçaie à Carex rostrata. Les stades plus évolués de la dynamique végétale subissent une forte érosion en terme de diversité et de densité d’insectes. Cette cariçaie est la formation dont la conservation est prioritaire., The authors analyze vegetal dynamics and Orthoptera communities of Crouzille’s peat bog (Monts d’Ambazac, Haute-Vienne, France). The depths of dig peat were related to present vegetation. The peaty shallow is characterized by an original orthopteran fauna, the most abundant species being Chorthippus montanus and Conocephalus discolor. During summer, Carex rostrata formation is the environment keeping the highest diversity of Orthoptera. Later stages in the vegetal dynamics undergo dramatic erosion in term of insect diversity and density. Conservation measures should concern the Carex rostrata formation in priority., Annales Scientifiques du Limousin, Tome 16 | 2005

Dociostaurus biskrensis Moussi and Petit sp. nov. (Fig. 1) Type material. Holotype male: found at Bir Naam, Biskra Wilaya, 222 m, 34 �� 45 ���N, 5 �� 8 ��� E, 02/07/ 2011, MNHN Paris. MNHN-EO-CAELIF 995 Allotype female: Bir Naam, 23 /07/ 2008, MNHN Paris. Paratype female: University of Limoges, found at Kantara, 11 /05/ 2013 Paratype male: University of Biskra, found at Bir Naam, 23 /07/ 2008 Description. Smaller than D. jagoi; brownish with sharp brown spots. The vertex is short, bordered by prominent carinae, with subacute apex; temporal foveolae longer than wide, adjacent to apex, with very sharp edges; frontal costa is slightly furrowed and pitted, and antennae are filiform. The pronotum has a well distinct white cross, especially in the metazone, edged with blackish-brown below. Hind femurs have very marked brown spots. Hind femur with the genicular lobe pale below in its inner and outer sides, as opposed to D. jagoi where they are much dimmed, at least on their inner sides. Hind tibiae slightly bluish with ten spines on each side. There are 67 to 93 stridulatory pegs on hind femora in the males, unlike D. jagoi jagoi in which their number ranges between 33 and 52. Tegmina exceed abdomen in both sexes, transparent with traces of brown spots. The wings are hyaline. Male subgenital plate short, conical and hairy. The male genitalia: The epiphallus formed by a bridge with well-developed horny ancorae and lophi bent twice. The penis is short and curved. The upper lobes of lophi in D. biskrensis are larger than in D. jagoi jagoi. Female: Slightly larger and more robust than males. The ovipositor valves are short, the lower valves with a few large pits below. Etymology. The " biskrensis " species epithet is derived from the name of locality of sampling (Biskra). Bio-ecology. Diet: The examination of 8 faeces of D. biskrensis collected in July for analyses showed that the species consumes a mixture of two types of grasses in the family Poaceae and four types of dicots. This species would be an ambivore. However, from 8 faeces of D. jagoi collected in August, we found 3 types of dicots with a very low percentage of grass. The diet is thus forbivorous to ambivorous. Phenology: As we identified two periods of appearance for adults and larvae during spring and autumn (Moussi et al., 2011), the cycle is probably bivoltine. There are two generations per year with embryonic overwintering, the mid-year period seeing the end of the first generation and the beginning of the second. On the other hand, according to Bounechada et al. (2006) and Guendouz-Benrima et al. (2011) D. jagoi jagoi is a univoltine species with a single generation throughout the year with an embryonic diapause. To discriminate the new species in the genus Dociostaurus, the morphometric measurements concerned the most relevant criteria defined by the following authors: Chopard (1943), Defaut (2004), and Garcia et al. (2005) (table 1). The characters are the number of pegs (Pegs) on the internal face of hind femurs, the length of the file or comb (File length), i.e. of the ridge bearing the pegs, the tegmina length (Tegmina), the head length, the total body length (total length), the femur width and length, and the pronotum length. If we compare the new species to the other Dociostaurus in North Africa, it shares with D. jagoi a smaller size (17���30 mm for males, 20���33 mm for females) than in the 3 other species of North Africa (D. dantini, D. hammadae and D. maroccanus). The Figure 2 displays the envelopes of six groups corresponding to the males and females of D. genei, D. jagoi jagoi and D. biskrensis. As the envelopes are quite distinct for females, it is easy to distinguish the three species between both species. However, the envelope of male D. biskrensis is separated from those of D. genei and D. jagoi jagoi. This is not really a problem as D. genei does not exist in North Africa (Eades et al. 2012). According to the Discriminant analysis (A.D., data not shown), the number of stridulatory pegs and the length of tegmina are the characters that contribute the most in the distinction between the D. biskrensis form the two other species either for males or females. This new species has more pegs on the internal ridge of its hind tibia (67 to 93 in males, 55 to 74 in females) than D. jagoi jagoi (33 to 52 in males, 26 to 48 in females). The internal ridge is also longer in D. biskrensis (Mean = 2.84 mm in males, 3.70 in females) than in D. jagoi jagoi (Mean = 2.28 in males, 2.61 in females) although there is an overlap between species. There is also an overlap for tegmina lengths between both species, but the easiest character to consider is the difference between hind knees and tegmina tips: 2.9 to 4.3 mm in D. biskrensis, and 2.2 to 3.8 in D. jagoi jagoi. As for Dociostaurus genei, we found 42 to 59 pegs in males, 48 to 64 in females, giving values close to D. jagoi jagoi.

Notopleura pygmaea Allotype male 7 /XI/09 Bir Naam, MNHN Paris. MNHN-EO-CAELIF 999 Description. Sandy brown, spotted by dark dots and white tubercles regularly aligned. The front head bears little elongated foveolae with clear edges. The pronotum has two white tubercles above and others distributed on the sides. The tegmina exceed the abdomen and are regularly adorned by white dots on the length. There are small white tubercules on the median nerve. The tibias are slightly bluish with 5 internal and 3 external spines, with an apical spine on the inner face. The internal spurs are longer than the external ones and reach the medium metatarsal. The wings are transparent. The hind femurs show two dark spots on the external side, but are clear inside. Bio-Ecology. There are two generations a year, in spring and autumn with a stop of embryonic development in winter. This species leaves in scrublands of sandy steppe (Moussi et al., 2011). Following the analysis of three faeces, it appears the presence of only Dicotyledone remains, suggesting that this species could be forbivore.

Pamphagulus uvarovi uvarovi Male Allotype, 7 /XI/09 Bir Naam, Biskra, MNHN, Paris. MNHN-EO-CAELIF 997 Description. smaller size and less rough than the previous species. The general coloring is variable from whitish brown to sandy whitish and also sometimes green whitish females in autumn. The antennae are of 15 articles. The pronotum is without gibbosity, finely high. There are 10 internal spines and 10 external spines on hind tibias. Genitalia: The study of male genitalia has demonstrated a difference between the epiphalle extracted from these two species (fig.). P. uvarovi lophi are almost straight and parallel to the ancorae whereas the lophi of P. b. dumonti are reflexed and are oblique to the ancorae. Therefore the epiphalle is considered as an important parameter to identify the species of P amphagulus. Morphometric analysis of Pamphagulus. We used morphometric data for analysis of the main components for the two sexes of Pamphagulus. The goal was to know the contribution of each variable and if the males and females of each species could be easily defined. The graph of the projection on the plane defined by axes F 1 and F 2 (fig. 4) after the analysis of the principal components of morphological data measured on males and females of Pamphagulus shows an opposition between males for both species. Indeed, the individuals of P. b. dumonti differ from other individuals of P.u. uvarovi by higher values of the total body length, width and length of femur, and pronotum length demonstrated by a discriminant analysis (AFD). However an overlap between females indicates a more difficult identification between females then between males. However, the femur width and the head length are slightly more important in P. b. dumonti than in P.u. uvarovi, and the contrary for femur length. Biology. The Pamphagulus are generally found very close or in the shrubs of Salsola: P. bodenheimeri dumonti in S. vermiculata and S. tetragona but P. uvarovi uvarovi in S. vermiculata spread in only one biotope. At the slightest noise or disturbance, they escape by jumping on the nearest bush and hide between the branches. Diet: Microscopic analysis of epidermal characters in Pamphagulus faeces revealed two types of the leaf epidermis remains. The most striking criterion in the distinction between these two Salsola species is the extension of the epidermal hairs, the hairs stretched out with regular branches in S. vermiculata, and the extensions of more or less long gloves in Salsola tetragona. From our analyses of the faeces, it clearly appears that the Pamphagulus only consume the plants of genus Salsola. P. uvarovi preferred feeding on S. vermiculata at 98.27 % and on S. tetragona at 1.73 %. On the other hand P. bodenheimeri dumonti preferred S. tetragona at 87.25 % and S. vermiculata 12.75 %. These results show that the 2 species of Pamphagulus are monophagous (a single genus) and has a diet adapted to the high salinity of halophytes. Phenology: P. uvarovi is a summer-autumn grasshopper leaving in a steppe environment (Moussi et al., 2011). The first adults are met from early July until late January. The peak is observed in September���October, indicating a single generation. A full coupling female was seen in the-mid August and another one at the end of December. The dissection of the ovaries of 7 females in December showed mature basal oocytes in their ovarioles. Dissected ovaries contained between 5 and 7 basal oocytes, yellow-orange and very elongated (5.38 mm in length and 1.35 mm in diameter). This reflects the biological activity and the predisposition to the egg-laying process. The absence of adults after this month until next July is indicating a period of embryonic or larval developmental arrest. P. b. dumonti is a species present almost all the year-round in dry spaces in an oasis environment where prevails a halophilic vegetation dominated by two species of Salsola. There are two periods during which adults were found to have a high density, indicating the presence of two generations. The mid-year period corresponds to the end of the 1 st generation and the beginning of the 2 nd one (Moussi et al., 2011). Eight females have been dissected in the month of April, but only 6 of them contained respectively 3, 4, 5, 6, 12 and 12 basal oocytes in their ovarioles. When we dissected 3 females in December, they contained 5 or 6 basal oocytes. That seems to confirm the two periods of ovarian activity of this species. This species show oocytes of the same color as the previous species, but of 4.73 mm in length and 1.39 mm in diameter. So the two Pamphagulus species are both pledged to Salsola bushes which constitute both food source and shelter. However, the two grasshopper species have a different diet specialization on Salsola leaves. Their habitat is also well separated: oasis for P. b. dumonti, allowing 2 generations a year and shorter oocytes, and steppe for P. u. uvarovi, allowing only one generation in the second half of the year but longer oocytes., Published as part of Moussi, Abdelhamid, Abba, Abderrahmane, Harrat, Abboud & Petit, Daniel, 2014, Description of Dociostaurus biskrensis sp. nov. and male allotypes of four species: Pamphagulus bodenheimeri dumonti, P. uvarovi, Sphingonotus ebneri and Notopleura pygmaea (Orthoptera: Acridoidea) in the region of Biskra, Algeria, pp. 379-390 in Zootaxa 3755 (4) on pages 385-388, DOI: 10.11646/zootaxa.3755.4.4, http://zenodo.org/record/230443, {"references":["Moussi, A., Abba, A., Harrat, A. & Petit, D.

The new species Dociostaurus biskrensis Moussi & Petit 2013 was collected in the region of Biskra, at the arido-Saharan limit of Eastern Algerian. We also describe the males of four species for which only females were known: Pamphagulus bodenheimeri dumonti, P. uvarovi, Notopleura pygmaea and Sphingonotus ebneri. The key to the genus Dociostaurus in North Africa is given. The species P. uvarovi and Notopleura pygmaea are new for the Algeria. The diets and life cycles of D. biskrensis and of the two species of Pamphagulus are defined.

The abundance, richness and seasonal composition of grasshopper communities (Caelifera) were studied in three natural wetland areas, in northeastern Algeria, near El-Tarf and El-Kala. A census of 19 species showed that 12 species were recorded at the station of Chtaïba (Quercus suber forest around 350 m A.S.L.), 11 in the marsh of Mekhada (around 30 m), and 10 in the station of El-Ghorra (Quercus canariensis forest, around 875 m). The different species were grouped into three assemblages, according to class frequency, and their temporal succession depended on the minima of monthly temperature, except at the El-Ghorra station. The assemblages corresponding to each station showed similar species richness and diversity, although their composition was quite different.[br/] The marsh station of Mekhada is characterized by littoral species, such as Eyprepocnemis plorans, Euchorthippus albolineatus, Tropidopola cylindrica and Platypygius platypygius. Together with Chorthippus vagans africanus, P. platypygius seem to be the most remarkable species of the region. There is an important lag in the abundance of adults at both forest stations compared to the littoral station. The richness of grasshopper assemblages was found to depend on the diversity of Poaceae.
