Taxonomy and evolution of the Canarian Issus Fabricius, 1803 (Hemiptera: Fulgoroidea: Issidae) based on morphological and molecular data

Abstract The genus Issus Fabricius, 1803 is divided into nine groups of species according to the structure of male genitalia. Phylogenetic position of the Canarian species of the genus is inferred with Bayesian and Maximum Likelihood analyses of four gene markers (COI, H3, CytB, 16S) dataset. Results revealed a well-supported basal dichotomy of the genus into two clades, corresponding to the Mediterranean and the Canarian species. This confirms the monophyly of the Canarian complex of Issus species which is divided into four clades corresponding to I. canariensis , I. rarus , I. bimaculatus , and I. hidipus groups of species. Our results contradict a previously published opinion on the primitiveness of the Canarian species, instead confirming the advanced position of this group. Issus canalaurisi Sergel, 1986 is placed in synonymy under I. cagola Remane, 1985, and I. maderensis Lindberg, 1954 – under I. climacus Fieber, 1876. Issus hidipus Remane 1985 is recorded for the first time from La Gomera and Tenerife Islands, I. padipus Remane 1985 – from El Hierro Island, and I. cagola – from Tenerife Island.
