Morphology and distribution of the external labial sensilla in Fulgoromorpha (Insecta: Hemiptera)

The present paper describes the sensory structures on the apical segment of the labium in fifteen fulgoromorphan families (Hemiptera: Fulgoromorpha), using the scanning electron microscope. Thirteen morphologically distinct types of sensilla are identified: five types of multiporous sensilla, four types of uniporous sensilla and four types of nonporous sensilla. Three subapical sensory organ types are also recognized, formed from one to several sensilla, each characteristic of a family group. Sensilla chaetica (mechanoreceptive sensilla) fall into three categories dependent on length and are numerous and evenly distributed on the surface of the labium except where they occur on specialized sensory fields. The planthopper morphological ground plan is represented by two apical pair of sensory fields (dorsal and ventral) on which 11 dorsal pairs of sensilla (10 peg-like pairs ? 1 specialized pair dome or cupola-like) and 2 ventral pairs of sensilla basiconica occur. Two main patterns (cixiid and issid) together with more specialized ones (derbid, lophopid, flatid and fulgorid) are reported. Disparity and diversity of the sensory structures are analyzed from a taxonomic and functional perspective. A gustatory function is provided for several chemoreceptive labial sensilla, as in the antennal flagellum sensilla in some other Hemiptera. This represents a more recently evolved function for the planthopper labium. Finally, further lines of study are suggested for future work on the phylogeny of the group based on the studied characters

The phylogenetic information carried by a new set of morphological characters in planthoppers : the internal mouthpart structures and test in the Cixiidae model (Hemiptera: Fulgoromorpha)

Internal morphological structures of Cixiidae mouthparts are described and compared in various representatives of the Cixiidae and several other representatives of hemipterans. The morphological study shows that the mouthpart structures have not evolved uniformly and reveals the great disparity of these structures. Particularly, the connecting system of the mouthparts, localisation of salivary canal and shape of the mandibular and maxillar stylets provide together a new set of 17 new characters. A parsimonious analysis to evaluate the phylogenetic interest carried by these 17 selected characters shows that mouthpart structures have not evolved anarchically, but that they indeed carry some phylogenetic information that will be useful to be included in further morphological phylogenetic analysis

Handicaps et EPS : une histoire à part ou à part entière ?

International audienceLa recherche d'une datation de la rencontre du handicap et de la discipline de l'Education physique et sportive (EPS) conduit au début des années 1980 lorsque l'arrivée de la gauche au pouvoir signe une bascule décisive pour la jeunesse handicapée. La mise en place du cadre organique d'une politique de l'Adaptation et de l'intégration scolaires (AIS), en rupture avec tradition d'éducation spéciale, offre alors à l'EPS, récemment adoptée par l'Education nationale, matière à prouver son utilité sociale en adaptant ses pratiques aux possibilités des élèves "autrement capables". Une histoire antérieure fait cependant état de la rencontre du handicap et du sport dès la paix retrouvée après le second conflit mondial, tandis qu'une histoire de plus longue durée montre l'importance de l'école primaire dans la transmission de l'éducation physique aux jeunes élèves, qu'ils aient été considérés comme infirmes ou inadaptés avant de relever de catégories nouvelles, telles celles du handicap et des besoins éducatifs particuliers. Ces trois dynamiques seront ici distinguées, non pour donner la primeur à l'une ou à l'autre, mais plutôt pour souligner l'épaisseur historique et les remaniements qui ont conduit à la composition du monde contemporain de l'inclusion scolaire à grande échelle

A bibliographic catalogue of the Cicadomorpha and Fulgoromorpha of North East Spain (Aragon)

The knowledge of a large number of Iberian Peninsula Hemiptera such as Cicadomorpha and Fulgoromopha is still fragmentary. Nevertheless, these two groups are especially remarkable because many species are endemic to this region while others are pests and/or vectors of diseases to cultivated plants. Therefore, information on these Hemiptera is important not only for conservation purposes, but also necessary for agricultural pest management. Within Spain, Aragon -located in the northeast of the country- is especially interesting due to the great diversity of habitats, rich flora and the strategic geographic position. For this political re gion, a bibliographic catalogue of Cicadomorpha and Fulgoromopha is here compiled. The results show that 136 species of 12 of the 15 families present in Iberian Peninsula have been reported in Aragon in previous works. Of these species, 17 percent are en demic to Spain and 15 percent were never mentioned in previous catalogues or checklists for the whole Iberian Peninsula. These results although exciting are clearly insufficient if we consider that several hundreds of species should be expected in this area; clearly more work should be done.info:eu-repo/semantics/publishedVersio

Catálogo de los hemípteros Cicadomorpha y Fulgoromorpha de Aragón

: Este es el primer catálogo bibliográfico realizado sobre los grupos de hemípteros Cicadomorpha y Fulgoromorpha de Aragón. Se han recogido los datos publicados desde Linneo hasta la actualidad. En total han sido citadas 136 especies en 46 trabajos realizados por 36 autores. Estas especies representan 12 de las 15 familias conocidas de la Península Ibérica, siendo un 17 por ciento de las especies endémicas de España y un 15 por ciento especies que nunca habían sido citadas de la Península Ibérica, ni en catálogos ni en listas de especies publicadas previamente. La fauna de Huesca, con 82 especies, es la mejor conocida de las tres provincias.This is the first bibliographic catalogue of the Hemiptera Cicadomorpha and Fulgoromorpha of Aragon (north-eastern Spain). A compilation has been made of data published from the time of Linnaeus up to the present. There were published records of a total of 136 species from this area, in 46 publications by 36 authors. These species represent 12 of the 15 families known from the Iberian Peninsula, with 17 per cent of the species being endemic to Spain; 15 per cent of the species had never been recorded from the Iberian Peninsula in the catalogues and species checklists published previously. The fauna of Huesca, with 82 species, is the best known of the three provinces.info:eu-repo/semantics/publishedVersio
