Premier inventaire faunistique des Chironomidés (Diptera : Chironomidae) des eaux courantes de Tunisie

Abstract

Pour la première fois, une liste faunistique de 81 taxa de Chironomidés -63 identifiés à l'espèce -récoltés par dérive dans 23 oueds du Nord, 2 oueds et 5 oasis du Sud de la Tunisie est présentée. La faune est à dominante paléarctique (55 espèces : 87,3 %). Les 12,7 % restants (8 espèces) sont des éléments de la faune méditerranéenne (3), nord-africaine (2), afrotropicale-ouest paléarctique (2), panpaléotropicalc (1). De nouvelles récoltes d'imagos et nymphes cr matures sont nécessaires pourconFirmer l'apparente nouveauté spéciFique de 5 types d'exuvies nymphales appartenant aux genres Larsia, Parakiefferiella, Paratanytarsus, Tanylarsus, Virgatany tarsus. 170 espèces de Chironomidés sont à présent recensées d'Afrique du Nord. First faunistic list of chironomids (Diptera : Chironomidae) for running-waters in TunisiaKeywords : Diptera, Chironomidae, faunistic, biogeography, Tunisia.For the first lime, a fau rial list with 81 taxa oF Chironomidae, 63 identified to species, is presented For Tunisia, using data from drift samples taken in 23 oueds from the North, 2 oueds and 2 oases from the South. The faunal list is dominated by palaearclic taxa (55 species : 87.3 %). The remaining 12.7 % (8 species) are from elements of the Mediterranean Fauna (3 species), north Africa (2 species), afrotropical-west palaearctic (2 species), panpalaeotropical (1 species). New collections of adults and male pupae were necessary to confirm the specific originality of five types of pupal exuviae belonging to the genera Larsia, Parakiefferiella, Paratanytarsus, Tanytarsus, Virgatany tarsus. 170 species of chironomids have been recorded from North Africa up to now.

Diversity and distribution of Chironomidae (Insecta: Diptera) of protected areas in North Tunisia

“…Both studies show similar proportions in the number of species among subfamilies with strong dominance of Chironominae. This research adds 39 new species of Chironomidae from Tunisia not recorded earlier (Boumaiza and Laville, 1988). As more than 49% of all the taxa recorded in this study are new for the study area and the number of recorded species quickly increase with any new data added (Figure 2), the present investigation predicts also the high potential of the Chironomidae diversity in the region.…”

“…These new data increase the number of species recorded in North Tunisia to 117. Table I presents the comparison of Boumaiza and Laville (1988) and our data. Both studies show similar proportions in the number of species among subfamilies with strong dominance of Chironominae.…”

“…As a result, fauna of wadi is relatively poor compared to continental European Mediterranean regions (Giudicelli et al, 1985;Lounaci et al, 2000a). The chironomid fauna of North-West Africa has been relatively well recognized in Marocco (Kettani et al, 2001;Langton, 2011), Algeria (Moubayed et al, 2007;Chaib et al, 2011Chaib et al, , 2013 while much less in Tunisia (Boumaiza, 1988). All faunistic data on non-biting midges in Tunisia have been summarized in the checklist of Chironomidae species recorded in this country (Boumaiza and Laville, 1998).…”

A contribution to the knowledge of the chironomid fauna (Diptera) in southern Portugal

“…85.3 % of the species found are also known in Spanish fauna (Cobo et al 1987, Soriano et al 1993, 56.2 % in Morocco (Azzouzi & Laville 1987, Azzouzi et al 1988, 30.3 % in Tunisia (Boumaiza & Laville 1988) and 61.9 % in the North Africa (Morocco, Tunisia or Algeria). Microchironomus tener, Polypedilum nubifer, Paratanytarsus bituberculatus and Paratanytarsus confusus previously recorded in North Africa and Spain (Ashe & Cranston 1990), were captured for the first time in Portugal.…”

Nouvelles récoltes de Chironomidés (Diptera) du Maroc : les Chironomidae de l'Oued Martil (Rif)

“…Rheotanytarsus pentapoda sont largement répandues dans la région circum-méditer-ranéenne (Moubayed & Laville 1983, Reiss 1985, 1986, 1989, Rossaro 1988, Boumaiza & Laville 1988, Casas & Vilchez 1989, Serra-Tqsio & Laville 1991 …”
