Taeniapion cf. diverserostratum - new cryptic species emerge

Besides the detailed presentation of the resynonymisation of Taeniapion diverserostratum (in ‘Weevils of Macaronesia’, STÜBEN in press), we seem to be dealing with another cryptic Taeniapion species on La Gomera. All the specimens we sequenced from the western islands using the CO1 gene (El Hierro, La Gomera, La Palma, Gran Canaria) fall into a clade that is clearly separated from the other known Macaronesian Taeniapion species. It is notable that the specimens from La Gomera and Tenerife form a coherent subclade with p-distances between 2.8 % and 3.8 %. The morphological differential diagnosis still causes difficulties, but the molecular discoveries pose a new question: Are we dealing with the reproductive isolation of another Taeniapion species on two neighbouring islands, namely La Gomera and Tenerife?
