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.

Sequences were analysed by parsimony and Bayesian analyses of aligned sequences aided by a new secondary structure model for the D2-D3 domains. Direct optimization was performed on ambiguous alignment regions in combination with fixed states optimization of unambiguous regions, but performed poorly compared to the Bayesian and parsimony analyses. Generally, the phylogenetic signal mainly resolved relationships within tribes, while deeper divergences were either not resolved or received marginal support. In addition to confirming several previously established clades, we found that Micracini formed the sister group to Cactopinus, a group of mainly cactus feeding scolytine beetles. Furthermore, Ipini was monophyletic with Pseudips and Acanthotomicus subtending to the most basal node of that Glade. The monophyly of Corthylini, which consists of the bark and cone feeding Pityophtorina and the ambrosia fungus-feeding Corthylina, was supported in some of the analyses. A close relationship was found between Phloeotribus and the two Phloeosinini genera Chramesus and Pseudochramesus, suggesting an evolutionary trajectory for the origin of a lamellate antennal club in Phloeotribus.10aAcanthotomicus10aCactopinus10aChramesus10aCorthylina10aCorthylini10aIpini10aMicracini10aPhloeosinini10aPhloeotribus10aPityophtorina10aPseudips10aPseudochramesus10aScolytinae1 aJordal, Bjarte1 aGillespie, Joseph, J.1 aCognato, Anthony, I.  uhttps://weevil.myspecies.info/secondary-structure-alignment-and-direct-optimization-28s-rdna-sequences-provide-limited-phylogeneti02243nas a2200193   4500008004100000020001400041245015100055210006900206260001000275300001200285490000700297520150700304653001501811100002501826700001601851700002401867700002301891856013501914       2011                        eng d  a0300-325600aPhylogeny of haplo-diploid, fungus-growing ambrosia beetles (Curculionidae: Scolytinae: Xyleborini) inferred from molecular and morphological data0 aPhylogeny of haplodiploid fungusgrowing ambrosia beetles Curculi  cMarch  a174-1860 v403 aThe ambrosia beetle tribe Xyleborini currently contains 30 genera and approximately 1200 species which are distributed throughout worldwide forests with most diversity located in the tropics. They also represent the most invasive scolytines in North America. Despite economic concerns and biological curiosity with this group, a comprehensive understanding of generic boundaries and the evolutionary relationship among species is lacking. In this study, we include 155 xyleborine species representing 23 genera in parsimony and Bayesian analyses using 3925 nucleotides from mitochondrial (COI) and nuclear genomes (28S, ArgK, CAD, EF-1a) and 39 morphological characters. The phylogenies resulting from the parsimony analyses, which treated gap positions either as missing or fifth character states, and the Bayesian analysis were generally similar. Clades with high support or posterior probabilities were found in all trees, while those with low support were not recovered by all analyses. Fourteen of the 23 genera were monophyletic although not all relationships among the genera were resolved. We show monophyly of several species groups associated with particular morphological and biological characters and suggest recognition of these groups as genera. Most interesting was the monophyly of South and Central American species representing several genera. This finding suggests recent and fast radiation of xyleborines in the New World accompanied by morphological and biological diversification.10aXyleborini1 aCognato, Anthony, I.1 aHulcr, Jiri1 aDole, Stephanie, A.1 aJordal, Bjarte, H.  uhttps://weevil.myspecies.info/phylogeny-haplo-diploid-fungus-growing-ambrosia-beetles-curculionidae-scolytinae-xyleborini-inferred02931nas a2200181   4500008004100000020001400041245015000055210006900205260001200274300001000286490000700296520221300303100002602516700002702542700001902569700002602588856013502614       2009                        eng d  a0300-325600aStructural alignment of 18S and 28S rDNA sequences provides insights into phylogeny of Phytophaga (Coleoptera: Curculionoidea and Chrysomeloidea)0 aStructural alignment of 18S and 28S rDNA sequences provides insi  cJanuary  a63-770 v383 aWe performed a comparative study of partial rDNA sequences from a variety of Coleoptera taxa to construct an annotated alignment based on secondary structure information, which in turn, provides improved rRNA structure models useful for phylogenetic reconstruction. Subsequent phylogenetic analysis was performed to test monophyly and interfamilial relationships of the megadiverse plant feeding beetle group known as 'Phytophaga' (Curculionoidea and Chrysomeloidea), as well as to discover their closest relatives among the Cucujiformia. Parsimony and Bayesian analyses were performed based on the structural alignment of segments of 18S rRNA (variable regions V4-V5, V7-V9) and 28S rRNA (expansion segment D2). A total of 104 terminal taxa of Coleoptera were included: 96 species of Cucujiformia beetles, representing the families and most 'subfamilies' of weevils and chrysomeloids (Phytophaga), as well as several families of Cleroidea, Tenebrionoidea and Cucujoidea, and eight outgroups from three other polyphagan series: Scarabaeiformia, Elateriformia and Bostrichiformia. The results from the different methods of analysis agree - recovering the monophyly of the 'Phytophaga', including Curculionoidea and Chrysomeloidea as sister groups. The curculionoid and chrysomeloid phylogeny recovered from the aligned 18S and 28S rDNA segments, which is independent of morphological data, is in agreement with recent hypotheses or concepts based on morphological evidence, particularly with respect to familial relationships. Our results provide clues about the evolutionary origin of the phytophagan beetles within the megaclade Cucujiformia, suggesting that the sister group of 'Curculionoidea + Chrysomeloidea' is a clade of the 'Cucujoidea', represented in this study by species in Boganiidae, Erotylidae, Nitidulidae, Cucujidae and Silvanidae. The Coccinellidae and Endomychidae are not grouped with the latter, and the remaining terminal taxa are nested in Tenebrionoidea and Cleroidea. We propose that the combination of structurally aligned ribosomal RNA gene regions 18S (V4-V5, V7-V9) and 28S (D2) are useful in testing monophyly and resolving relationships among beetle superfamilies and families.1 aMarvaldi, Adriana, E.1 aDuckett, Catherine, N.1 aKjer, Karl, M.1 aGillespie, Joseph, J.  uhttps://weevil.myspecies.info/structural-alignment-18s-and-28s-rdna-sequences-provides-insights-phylogeny-phytophaga-coleoptera-cu00516nas a2200109   4500008004100000245012300041210006900164300001000233490000700243100002100250856013500271       2005                        eng d00aLarval morphology and biology of oxycorynine weevils and the higher phylogeny of Belidae (Coleoptera, Curculionoidea).0 aLarval morphology and biology of oxycorynine weevils and the hig  a37-480 v341 aMarvaldi, A., E.  uhttps://weevil.myspecies.info/larval-morphology-and-biology-oxycorynine-weevils-and-higher-phylogeny-belidae-coleoptera-curculiono00527nas a2200109   4500008004100000245013300041210006900174300001200243490000700255100002000262856013500282       1992                        eng d00aRevision of Trachodema Blanchard with the description of an allied genus from central Chile (Insecta, Coleoptera, Curculionidae.0 aRevision of Trachodema Blanchard with the description of an alli  a417-4220 v211 aMorrone, J., J.  uhttps://weevil.myspecies.info/revision-trachodema-blanchard-description-allied-genus-central-chile-insecta-coleoptera-curculionida00517nas a2200121   4500008004100000245010600041210006900147300001200216490000700228100002000235700001500255856012500270       1995                        eng d00aAcroriellus, a new weevil genus of northern Andean Listroderina (Insecta: Coleoptera: Curculionidae).0 aAcroriellus a new weevil genus of northern Andean Listroderina I  a257-2620 v241 aMorrone, J., J.1 aOcampo, F.  uhttps://weevil.myspecies.info/acroriellus-new-weevil-genus-northern-andean-listroderina-insecta-coleoptera-curculionidae00522nas a2200109   4500008004100000245013300041210006900174300001200243490000700255100001500262856013500277       2002                        eng d00aRevision of the subgenus Neosynaptops Voss of Euops Schoenherr (Coleoptera, Curculionoidea, Attelabidae) from the Papuan region.0 aRevision of the subgenus Neosynaptops Voss of Euops Schoenherr C  a135-1650 v311 aRiedel, A.  uhttps://weevil.myspecies.info/revision-subgenus-neosynaptops-voss-euops-schoenherr-coleoptera-curculionoidea-attelabidae-papuan-re01590nas a2200157   4500008004100000245012800041210006900169260001200238300001000250490000700260520104600267100001501313700001501328700001401343856007501357       2009                        eng d00aDeep cox1 divergence and hyperdiversity of Trigonopterus weevils in a New Guinea mountain range (Coleoptera, Curculionidae)0 aDeep cox1 divergence and hyperdiversity of Trigonopterus weevils  c01/2010  a63-740 v393 aTrigonopterus is a little-known genus of flightless tropical weevils.
