I. The Madeiran clade0 aMitochondrial DNA phylogenetic analysis of the genus Laparocerus  cJuly  a415-4270 v373 aLaparocerus are plant-chewing flightless weevils distributed on oceanic islands in Macaronesia, with a single species in Morocco. The genus has a complicated taxonomic history with several subgenera described. To assist in a taxonomical revision of the group, a molecular study was undertaken. In this first contribution, the species from the Azores and Madeira archipelagos are studied together with representatives of subgenera from the Canary Islands and the single known continental species (46 OTUs). Phylogenetic analyses are based on sequence data from mitochondrial cytochrome oxidase II (COII) and the ribosomal 16S ribosomal RNA (16S rRNA) genes (combined data set 1023 bp), with additional data from the nuclear elongation factor 1[alpha] (EF-1[alpha]) for some selected species. Maximum likelihood (ML) and Bayesian analyses show that all Madeiran species are monophyletic and form a monophyletic group with the Afro-Canarian samples. Species of the genus Lichenophagus appear within the Madeiran and Canarian Laparocerus clades, but separated in accordance with their respective island origin. Thus, Lichenophagus is here restricted to Madeiran species and proposed as subgenus (status novo) of Laparocerus. Conversely, the Laparocerus subgenus Drouetius from the Azores is revealed to be a separate and distant outgroup, in agreement with its morphological distinctiveness, deserving an independent genus status. Internal relationships within the Madeiran clade are discussed and compared with morphologically defined species groups. The Madeiran monotypic subgenus Cyphoscelis is not supported by the genetic data and synonymized (nov. syn.) with Laparocerus. Subgenera Laparocerus and Atlantis prove to be polyphyletic. Consequently a restriction to monophyletic and morphologically congruent clades is proposed. A cryptic species vicariant of Laparocerus morio was detected and recognized as L. chaoensis, status novo. Other cases of discrepancy between the genetic results and the traditional taxonomy are discussed in detail in the light of mitochondrial introgression, incomplete lineage sorting or poor taxonomy hypotheses.10aAtlantis10aCyphoscelis10aDrouetius10aLaparocerus10aLaparocerus (Lichenophagus)10aLaparocerus chaoensis10aLaparocerus morio10aLichenophagus1 aMachado, Antonio1 aLopez, Mercedes1 aAlmeida, Teresa1 aHernandez, Mariano  uhttps://weevil.myspecies.info/mitochondrial-dna-phylogenetic-analysis-genus-laparocerus-coleoptera-curculionidae-entiminae-i-mad-002098nas a2200289   4500008004100000020001400041245010900055210006900164260000900233300001000242490000700252520109500259653001401354653002301368653003001391653004001421653003401461653002201495653003201517653003801549653002401587653003201611653001601643653001401659100001601673856011901689       2009                        eng d  a0367-504100aThe genus Drouetius Mequignon, 1942, stat. prom., from the Azores (Coleoptera, Curculionidae, Entiminae)0 agenus Drouetius Mequignon 1942 stat prom from the Azores Coleopt  c2009  a19-460 v653 aDrouetius Mequignon, 1942, was originally established as a monotypical subgenus of Laparocerus Schonherr, 1834, and is here upgraded to genus (stat. prom.) based on morphological and molecular data.
