摘要
Hoverflies are relevant to pollination, predation, phytophagy and decomposition processes and they are also used as bio-indicators. The numerous recent advances in the study of Spanish hoverflies and the absence of species lists for the Spanish provinces prompted us to update the national catalogue and fill in the gap at the provincial level. Andorra and Gibraltar are also included in this review. A total of 421 species of 72 genera are included in the present catalogue (417 species in Spain; 86 in Andorra; 43 in Gibraltar). Leon (182 spp), Salamanca (143 spp), Madrid (134 spp), Ciudad Real (124 spp) and Huesca (121 spp) are the Spanish provinces with the highest numbers of species recorded. The Balearic Islands have 81 species and the Canary Islands 41, with one and 11 endemic species respectively. The richest hoverfly genera in Spain are Cheilosia (56 spp), Merodon (40 spp plus 1 sp from Gibraltar) and Eumerus (38 spp plus 1 sp from Gibraltar), all of them being Eristalinae; within the Syrphinae, Paragus is the richest genus (18 spp). The possibility of elaborating regional (provincial) species lists from the information provided in the present study also contributes to 'Syrph the Net, the database of European Syrphidae' as a tool for assessment of habitat conservation in Spain.
