Présence de Cicadetta brevipennis Fieber, 1876 en Alsace (Hemiptera, Cicadidae)
Abstract
Résumé : trois espèces de cigales ont été signalées en Alsace par Döderlein (1914) : Lyristes plebejus (Scopoli, 1763), Tibicina haematodes (Scopoli, 1763) et Cicadetta montana (Scopoli, 1772). L'observation de L. plebejus doit être considérée comme erronée, et T. haematodes n'a plus été signalée depuis. Les Cicadetta du groupe montana n'étant identifiables que par la cymbalisation, toutes les données historiques de C. montana doivent être attribuées au complexe Cicadetta cf. montana. Une cartographie des données anciennes et récentes de Cicadetta cf. montana en Alsace est donnée. Dans les stations du Haut-Rhin et Bas-Rhin où nous avons pu enregistrer la cymbalisation des Cicadetta, il s'agissait toujours de Cicadetta brevipennis Fieber, 1876. cette espèce est donc signalée pour la première fois en Alsace.
Zusammenfassung : Das Vorkommen von Cicadetta brevipennis Fieber, 1876 im Elsass (Hemiptera, Cicadidae).
Drei Arten von Singzikaden sind von Döderlein (1914) für das Elsass gemeldet worden: Lyristes plebejus (Scopoli, 1772). Die Beobachtung von L. plebejus muss als Falschmeldung betrachtet werden und T. haematodes wurde seither nicht mehr gemeldet. Da die Cicadetta-Arten aus der Gruppe montana nur nach ihrem Gesang zu bestimmen sind müssen alle alten Meldungen über C. montana der Artengruppe Cicadetta cf. montana zugeordnet werden. Eine Karte der alten und neuen Funde von Cicadetta cf. montana im Elsass wird vorgestellt. Bei allen Fundorten im Departement Haut-Rhin und Bas-Rhin, wo wir den Gesang von Cicadetta registrierten, handelte es sich immer um Cicadetta brevipennis. Diese Art wird also zum etrsten Mal für das Elsass gemeldet.

... In these cases taxon assignment to the various Cicadetta brevipennis group taxa is based on biogeography and must be verified especially for black dotted populations. Some of the records were previously published, essentially records of the cerdaniensis group [2,[38][39][40][41][42]65,[71][72][73][74][75][76][77][78][79]. *Brown dots are observations of Cicadetta brevipennis without assignment to a subspecies in Central Italy. ...
... Often brevipennis group taxa sing in lower substrates (small bushes, herb layer) than is usually known for C. montana s. str. or for the cerdaniensis song group [39,40,74,77]. Cicadetta brevipennis group species tend to live in drier habitats than cerdaniensis group species. ...
... At third priority are the completely fragmented local populations of C. petryi remote from the core populations in southern France. It is rare with regionally restricted habitat requirements in Switzerland, Germany and Italy as well as in northern France [40,65,74,77]. Many of these isolated populations appear as relicts of a postglacial warmer period with tens of kilometres between them. ...
Multiple sources of data in combination are essential for species delimitation and classification of difficult taxonomic groups. Here we investigate a cicada taxon with unusual cryptic diversity and we attempt to resolve seemingly contradictory data sets. Cicada songs act as species-specific premating barriers and have been used extensively to reveal hidden taxonomic diversity in morphologically similar species. The Palaearctic Cicadetta montana species complex is an excellent example where distinct song patterns have disclosed multiple recently described species. Indeed, two taxa turned out to be especially diverse in that they form a “complex within the complex”: the Cicadetta cerdaniensis song group (four species studied previously) and Cicadetta brevipennis (examined in details here). Based on acoustic, morphological, molecular, ecological and spatial data sampled throughout their broad European distribution, we find that Cicadetta brevipennis s. l. comprises five lineages. The most distinct lineage is identified as Cicadetta petryi Schumacher, 1924, which we re-assign to the species level. Cicadetta brevipennis litoralis Puissant & Hertach ssp. n. and Cicadetta brevipennis hippolaidica Hertach ssp. n. are new to science. The latter hybridizes with Cicadetta brevipennis brevipennis Fieber, 1876 at a zone inferred from intermediate song patterns. The fifth lineage requires additional investigation. The C. cerdaniensis and the C. brevipennis song groups exhibit characteristic, clearly distinct basic song patterns that act as reproductive barriers. However, they remain completely intermixed in the Bayesian and maximum likelihood COI and COII mitochondrial DNA phylogenies. The closest relative of each of the four cerdaniensis group species is a brevipennis group taxon. In our favoured scenario the phylogenetic pairs originated in common Pleistocene glacial refuges where the taxa speciated and experienced sporadic inter-group hybridization leading to extensive introgression and mitochondrial capture.
... La répartition de cette espèce en France est livrée par la Figure 20 où elle apparaît être présente aussi bien dans la moitié nord que la moitié sud de la France. Anciennement connue du quart nord-est de la France (Doderlein, 1914 ;Hugel & al., 2008), T. haematodes semble aujourd'hui avoir disparu de cette partie du territoire national. Cette espèce émet sa cymbalisation pour une large plage de températures mais limite son activité lorsque la température moyenne dépasse les 30°C. ...
Cinquante trois stations ont été échantillonnées sur le massif du Bois de Païolive (Ardèche, France) sur une période de prospections de six jours menées en juin 2012. Six espèces de cigales furent relevées au sein du périmètre d’étude. Une espèce, Dimissalna dimissa (Hagen, 1856), est patrimonialement intéressante, étant en limite d’aire occidentale de répartition. Pour chaque espèce de cigale, une cartographie de leur répartition est livrée pour le Massif ainsi qu’une représentation graphique spécifique caractérisant leurs émissions sonores. Des traits d’écologie et de comportement sont donnés et replacés dans le contexte bibliographique portant sur la connaissance de chaque espèce.
... one historic population is mentioned from the vineyards in Rouffach (Alsace, France) situated only 50 km north of Basel (döderlein, 1913;Huber, 1916). 16 specimens of this time are deposited in the collection of the Zoological Museum of strasbourg labelled with the nearby village of Westhalten (Hugel et al., 2008). The german population nearest to switzerland was described from Tübingen (Baden-Württemberg) with a population of 80 to 100 specimens (schwoerbel, 1957). ...
Cicadas are charismatic and are widely appreciated, even by the general public, but knowledge of species diversity and distribution is patchy, incomplete and sometimes misleading. This study presents an overview on the historic and current knowledge on the cicadas of Switzerland. For the first time, data retrieved from historic and recent literature, reviewof public and private collections and detailed recent field-work including up-to-date recording techniques have been combined. Our work during the last decade has resulted in the doubling of the number of known species. We now report the existence of ten native species in Switzerland: Cicada orni, Lyristes plebejus, Tibicina quadrisignata, T. steveni, T. haematodes, Cicadetta montana s. str., C. cantilatrix, C. sp. aff. cerdaniensis, C. brevipennis and Tettigettalna argentata. All species are presented, with detailed distribution maps, data on habitat and conservation status. Cicada hotspots are the southern Swiss cantons of Valais, Ticino and Geneva. Nine species have restricted habitat requirements, seven species are rare and three species are of high national conservation importance in Switzerland.
