The specimens studied were collected with sweep net and pitfall in the forests, agro-forests, herbaceous fallows, crop fields of 14 localities southern part Cameroon, from August 2015 to February 2018. results show that Heteracris hannai sp. nov. lecoqi differ previously known species same genus by pattern coloration details or shape phallic complex. H. is characterized light brownish body; male cercus flattened, downcurved obtuse apex; lophus strongly curved; interlophal space V shape;...
Abstract Overexploitation of wildlife is pervasive in many tropical regions, and addition to being a significant conservation sustainability concern, it has received global attention given discussions over the origins zoonotic disease outbreaks. Where unsustainable, consumption wild meat by urban residents been identified as major socio‐environmental challenge, driver declines. Yet, information on consumers possible ways target interventions remains lacking. Using one largest datasets (1391)...
Gryllotalpa weisei Simeu-Noutchom Kekeunou sp. nov. was collected only in Tombel the South-West region of Cameroon, during a survey conducted from March 2016 to 2018 West, and Centre regions Cameroon. This species is close microptera, for first time Cameroon these investigations, West region. G. different microptera due hind wings that are vestigial; average fore length 5.85±0.56 mm male 5.34±0.45 female, not reaching fifth abdominal segment; anal end slightly concave; stridulatory file with...
A survey was conducted in two successive years, from March 2016 to 2018, three regions of Cameroon, during which new species were collected and described. These species, Gryllotalpa cameroonensis sp. nov. tamessei caught using the pitfall method forests, agroforests, herbaceous fallows, crop fields. From an ecological point view, both accidental all vegetation types except fields, accessory. Their habitat characteristics might require sandy soil for G. silty nov., as well low moisture acid...
The genus Macroscirtus belongs to the subfamily Mecopodinae with five recognized species distributed in central-west tropical Africa. All are known from very few localities. reviewed and, addition, a new Cameroon is described. kekeunoui sp. nov. characterized by tegmina not reaching penultimate abdominal segment; hind femura mottled brown external face, ventral and internal face completely pale yellow; male subgenital plate elongated horizontally, indentation edge straight. Species...
Forest degradation due to human activities is a major threat the long-term persistence of many species. It affects species richness, abundance and can lead extinction some The present work aimed at identifying effect environmental variations on richness composition grasshoppers in three regions Cameroon. In each region, four vegetations (forests, agroforests, fallows crop fields) were investigated using sweep nets pitfalls trapping for specimens’ capture from February 2016 2018. From this...
Three species of the africana-group Genus Gryllotalpa (Orthoptera: Gryllotalpidae) were recorded from Cameroon during an investigation March 2016 to 2018: africana Beauvois Buea and Tombel, two new species, tombelensis Simeu-Noutchom Kekeunou sp. nov. Tombel babetensis Babété. is characterised by short wing morphology, vestigial hind wings, small phallic complex, internal processes, dorsoventrally flattened body. distinct other mesoscutum being more exposed between pronotum base fore having...
For a better knowledge of Atractomorpha acutipennis bio-ecology and to facilitate its identification, we studied the morphology, development reproduction this grasshopper on Manihot esculenta under laboratory conditions. Five hundred fifty-one first nymphal stages obtained in were reared cages. Some body parts allowed clear identification different instars. Post-embryonic passed through six (males) seven (females). Mean time was 17.14 ± 0.62, 12.91 13.45 0.69, 13.80 0.68, 15.23 0.55 days...
During a Gryllidae survey in the Southern Cameroonian Plateau, two new species of tribe Turanogryllini Otte, 1987 were discovered and described, namely Turanogryllus zamakoensis Um Nyobe, Kekeunou & Bilong sp. nov. Neogryllopsis gorochovi Ma This finding extends known distribution genera Tarbinsky, 1940 1983. New environments are also recorded for these crickets, an identification key African is proposed genera.
Taxonomy and bio-ecology of Tetrigidae in Cameroon remain poorly studied. This study reports for the first time presence Thibron cf. tectatus Günther, 1979 provides morphological bio-ecological characteristics illepidus (Karsh, 1893) T. tectatus. The specimens studied were collected between February 2016 2018 three regions Cameroon. In each region, species monthly using sweep-nets pitfalls four vegetation types. Some characters formerly omitted previous descriptions considered this study....
