Abstract:Examination of Fulgoroid specimens collected in several caves of volcanic origin on the Canary Islands (Tenerife, El Hierro) has revealed the existence of at least two undescribed troglobitic Fulgoroid species. These are apparently the first records of troglobitic Auchenorrhyncha, not only from the Middle Atlantic Islands, but from the Palaeartic Region. These cavernicolous taxa belong to the families Cixiidae (Tachycixius lavatubus sp. nov.) and Meenoplidae (Meenoplus cancavus sp. nov.). Possible pathways towards the evolution of troglobitic forms in Auchenorrhyncha and ways of speciation?sympatric or allopatric?for T. lavatubus sp. nov. and its epigean relative Tachycixius canariensis (Lindberg) are discussed. These findings suggest that cavernicolous Homoptera are more widely distributed over the world than was previously assumed.Examination of Fulgoroid specimens collected in several caves of volcanic origin on the Canary Islands (Tenerife, El Hierro) has revealed the existence of at least two undescribed troglobitic Fulgoroid species.
