Received 21 March 2015 | Accepted 31 August 2015 | Published 30 September 2015
New genera, species and records of Afrotropical Phaneropterinae (Orthoptera, Tettigoniidae) preserved at the Royal Belgian Institute of Natural Scien…
2017
The results of the study of the rich material of Orthoptera Phaneropterinae at the Royal Belgian Institute of Natural Sciences, Bruxelles, are reported. The following new taxa are described: Dithela longicaudata n. sp. from the Democratic Republic of Congo, Terpnistriella bredoi n. gen. n. sp. from the Democratic Republic of Congo, Mimoscudderia paulyi n. sp. from the Madagascar, Pseudogoetia constanti n. gen. n. sp. from the Democratic Republic of Congo (including a table listing differences with related genera), and Materuana abyssinica n. sp. from the Ethiopia. Some taxonomic and distributional data about the following species are also reported: Melidia claudiae Massa, 2015, Symmetrokars…
New taxa of Orthoptera (Insecta Tettigoniidae Phaneropterinae) from Madagascar.
2017
The author reports the results of a study on Orthoptera collected in Madagascar and preserved in two European Natural History museums. He describes Symmetroraggea depravata n. sp., Parapyrrhicia longipodex n. sp., Madagascarantia bartolozzii n. gen. n. sp., Mimoscudderia spinicercata n. sp. In addition, he lists new records or unknown taxonomical characters of Xenodus nobilis Carl, 1914 and Parapyrrhicia virilis Carl, 1914.
New data and taxa for Orthoptera Tettigoniidae and Acrididae from tropical Africa.
2017
The results of a long-term study on the Orthoptera collected in tropical Africa and preserved in different European natural history museums are reported. Horatosphaga bazeletae n. sp. is described from South Africa, Dapanera falxcercata n. sp. from Cameroon, Eurycorypha specularia n. sp. from Zambia (Tettigoniidae Phaneropterinae), and Eucoptacra popovi n. sp. (Acrididae Coptacrinae) from the Gabon. Furthermore, the new genus Pigalua n. gen. is described for Eulioptera insularis Ragge, 1980 from Annobón Is. (Equatorial Guinea). The new tribe Kevaniellini n. trib. is proposed for Kevaniella bipunctata Chopard, 1954. Besides, the hitherto unknown males of Eurycorypha flavescens (Walker, 1869)…
Etude diagnostique de nouvelles données climatiques : les réanalyses. Exemples d'application aux précipitations en Afrique tropicale
2000
This study establishes an objective diagnosis of NCEP/NCAR reanalysis data reliability over tropical Africa at intra-seasonal to interannuel space scale. The reanalysis data are an original database available over 1958-1998 period which combines observations and atmospheric model outputs and allows us to better understand global scale atmospheric dynamics. The study of data reliability allows us to identify a great number of recommendations for using them. Over tropical Africa, the homogeneous period which should be extracted goes from 1968 to 1998. Before this year, reanalysed datasets should be used with greatest caution. However, during this period, the SMWDA, a statistical method used t…
New genera, species and records of Phaneropterinae (Orthoptera, Phaneropteridae) from sub-Saharan Africa
2015
The results of the study of many specimens preserved in different European museums are reported. The tribe Terpnistrini Brunner von Wattenwyl, 1878 is resurrected. The distribution of the following species is enhanced: Pardalotaasymmetrica Karsch, 1896, Diogenadenticulata Chopard, 1954, Diogenafausta (Burmeister, 1838), Plangiopsisadeps Karsch, 1896, Poreuomenasanghensis Massa, 2013 and Tylopsiscontinua (Walker, 1869). Further, for their peculiar characteristics, two African representatives of the American genus Symmetropleura Brunner von Wattenwyl, 1878 are included in two new genera: Symmetrokarschiaafricana (Brunner von Wattenwyl, 1878), comb. n. and Symmetroraggeadirempta (Karsch, 1889)…
The identity of the tropical African
2016
Abstract Polichne mukonja Griffini, 1908 from Cameroon was hitherto known only from the holotype preserved at the Royal Belgian Institute of Natural Sciences, Brussels. This was probably due to the fact that the genus Polichne Stål, 1874 distributed only in Australia and Papua New Guinea. In view of this distribution, the tropical African species was therefore overlooked in the African literature. The recent discovery of two specimens at the Naturhistorisches Museum, Vienna, now provides us with a better understanding of the identity of this taxon, which is related to the African genus Catoptropteryx Karsch, 1890. Polichne mukonja is here transferred to a new genus Griffinipteryx and both t…
