Exophthalmus presently includes more than 80 species, approximately half of which are restricted to either the Caribbean archipelago or the continental Neotropics. The taxonomic composition and position of Exophthalmus have been subject to longstanding disagreements; in particular, authors have questioned the relationship of Exophthalmus to other Caribbean genera such as Diaprepes Schoenherr, 1834 (Eustylini) and Lachnopus Schoenherr, 1840 (Geonemini Gistel), as well as to the speciose Central and South American genera Compsus Schoenherr, 1823, Eustylus Schoenherr, 1842, and Exorides Pascoe, 1881 (all Eustylini), among others. The present study scrutinizes these traditional perspectives, based on a cladistic analysis of 143 adult morphological characters and 90 species, representing 30 genera and seven tribes of Neotropical entimine weevils. The character matrix yielded eight most-parsimonious cladograms (length = 239 steps; consistency index = 66; retention index = 91), with mixed clade support that remains particularly wanting for some of the deeper in-group divergences. The strict consensus supports the existence of a paraphyletic Geonemini grade that includes Lachnopus and related Caribbean genera such as Apotomoderes Dejean, 1834, followed by a monophyletic Eustylini in-group clade. Within the latter, a monophyletic South American Eustylini clade including Compsus, Eustylus, Exorides, and related genera is sister to a major clade that contains a grade of heterogeneous and often misclassified Caribbean members of the Eustylini, Geonemini (Tetrabothynus Labram&Imhoff, 1852 and Tropirhinus Schoenherr, 1823), and Tanymecini Lacordaire (Pachnaeus Schoenherr, 1826), as well as two major clades: one with the majority of Central American Exophthalmus species, and the other with most Caribbean members of Exophthalmus. The Central American Exophthalmus clade is paraphyletic with respect to Chauliopleurus Champion, 1911 (Geonemini) and Rhinospathe Chevrolat, 1878 (Phyllobiini Schoenherr). The Caribbean clade, in turn, contains two subclades: i.e. (1) the Greater Antillean Exophthalmus s.s. clade, including the type species Exophthalmus quadrivittatus (Olivier, 1807); and (2) the primarily Lesser Antillean Diaprepes. The latter genus is therefore nested within Central American and Caribbean species of a highly paraphyletic Exophthalmus, yet may be rendered monophyletic if several Lesser Antillean Exophthalmus species are (re-)assigned to Diaprepes. The results thus provide a suitable basis for a revision of all Exophthalmus species, and furthermore suggest that historical biographic factors, including colonization via temporary continental Neotropics-to-Caribbean land connections, were important in the evolution of major eustyline lineages. Based on these preliminary insights, the following taxonomic and nomenclatural adjustments are made. Compsoricus gen. nov. is erected to accommodate two Puerto Rican species erroneously assigned to Compsus: i.e. the herein designated type species Compsoricus maricao comb. nov. and Compsoricus luquillo comb. nov. Eustylus dentipes comb. nov. is transferred from Compsus. Diaprepes marginicollis Chevrolat, 1880 is reinstated from synonymy under Exophthalmus. Lastly, the following five transfers are proposed: (1) Chauliopleurus Champion, 1911, from Geonemini to Eustylini; (2) Tetrabothynus Labram&Imhoff, 1852, from Geonemini to Eustylini; (3) Tropirhinus Schoenherr, 1823, from Geonemini to Eustylini; (4) Rhinospathe Chevrolat, 1878, from Phyllobiini to Eustylini; and (5) Pachnaeus Schoenherr, 1826, from Tanymecini to Eustylini.10aApotomoderes10aCompsus10aEustylini10aEustylus10aExophthalmus10aExorides10aGeonemini10aLachnopus10aTanymecini10aTetrabothynus10aTropirhinus1 aFranz, Nico, M.  uhttps://weevil.myspecies.info/phylogenetic-reassessment-exophthalmus-genus-complex-curculionidae-entiminae-eustylini-geonemini01424nas a2200169   4500008004100000020001400041245008000055210006900135260001200204300001100216490000800227520086200235653001401097653001501111100002201126856010601148       2011                        eng d  a0024-408200aDelimiting baridine weevil evolution (Coleoptera: Curculionidae: Baridinae)0 aDelimiting baridine weevil evolution Coleoptera Curculionidae Ba  cJanuary  a88-1560 v1613 aSince the erection of the weevil subfamily Baridinae by Schonherr in 1836, no phylogenetic hypothesis using cladistic methods has been proposed for this extraordinarily diverse group. This study provides the first hypothesis for the evolution of Baridinae using phylogenetic methods, including 301 taxa and 113 morphological characters. Despite fairly well-resolved results, indicating paraphyly of nearly all of the currently recognized intrasubfamilial divisions, no change to the current classification is made. Even though groupings are proposed based on the final results, it is believed that more rigorous analyses need to be made prior to a re-evaluation and subsequent alteration of the current classification.

The Bayesian reconstruction is supplemented by observations on morphology, ecology, and reproductive biology. The present study often corroborates the groups previously outlined in higher-level informal taxonomies. These and further groups are now assigned new taxonomic status. The following genera and subgenera are described (formerly Acalles): Aeoniacalles gen. nov., Canariacalles gen. nov., Ficusacalles gen. nov., Madeiracalles gen. nov., Silvacalles gen. nov. (with Tolpiacalles subgen. nov., Tagasastacalles subgen. nov.), Sonchiacalles gen. nov., Echiumacalles gen. nov. (monotypic), Lauriacalles gen. nov. (monotypic), and Pseudodichromacalles gen. nov. (monotypic; formerly Dichromacalles). For the western Palaearctic genus Acalles Schoenherr, 1825 the first subgenus Origoacalles subgen. nov. is described and for the genus Onyxacalles Stüben, 1999 the first subgenus Araneacalles subgen. nov.; Paratorneuma Roudier 1956 resyn. Except for one species of Acalles (Origoacalles), all of these new higher taxa are endemic to the Macaronesian Islands. All new taxa are presented, together with their host plants and further data, in a synoptic tabular overview. Based on the results of our phylogenetic analysis, we advocate the hypothesis that the evolution of the species in the new genera (of which most group into a ‘Macaronesian clade’) began in the comparatively arid succulent bush zone and that the shady and humid laurel forest of the thermo-Canarian and thermo-Madeiran zone was entered much later. Our reconstruction implies that the Canarian and Madeiran archipelagos were colonized by Cryptorhynchinae at least seven times from the continent but saw only one considerable adaptive radiation. It also becomes apparent that it is the ancestor species of the genus Canariacalles – and not Pseudodichromacalles – that features a close connection to the south-western European and north-western African species of Dichromacalles s.s. Finally, a key is presented for all genera and subgenera of the Macaronesian Cryptorhynchinae.1 aStüben, P.E.1 aAstrin, Jonas, J.  uhttps://weevil.myspecies.info/molecular-phylogeny-endemic-weevils-revision-genera-macaronesian-cryptorhynchinae-coleoptera-curculi
