“…The extent to which this is the case on the islands is not entirely clear, however. While herbivorous insects dominate the faunas (Chown and Convey 2016), the majority of species are polyphagous or detritivores (Kuschel 1971, Crafford et al 1986, Chown 1989, Morrone 2011. Given what is known also of local-scale distributions, it seems likely that a combination of these factors has been important in influencing diversity variation, together with some opportunity for local speciation as a consequence of glacial history Convey 2016, Moon et al 2017).…”

Simultaneously investigating variation in species richness and turnover for indigenous and introduced communities holds great promise as a means to understand the relative contributions of ecological processes to community structure. Such insight will advance understanding of the ways in which environmental change may affect future community dynamics. Using a recently developed multi‐site turnover metric, zeta diversity (ζ), we explored species turnover patterns across indigenous and introduced insect and vascular plant communities of the Southern Ocean Islands. In addition, we used updated species occurrence and high‐resolution environmental data to reexamine previously described patterns and drivers of species richness across the region. Species richness variation in indigenous insect and vascular plant communities was largely explained by island isolation and temperature, whereas human visitation frequency was strongly associated with introduced species diversity of both groups. Indigenous communities of both plants and insects had faster rates of species turnover across sites and less inter‐island connectivity than their introduced counterparts. Zeta diversity analyses suggested that stochastic processes were more influential than niche‐related processes on the observed patterns of turnover of indigenous insects. Meanwhile, turnover patterns of introduced insects and indigenous and introduced vascular plants were indicative of the dominance of niche‐related processes. These outcomes highlight very different diversity patterns across indigenous and alien communities and indicate that different ecological processes may underlie diversity variation across these islands and taxonomic groups.

“…For the present study I examined species of the genera previously recognized for the tribe (Morrone 2011). The outgroup taxa included the genera Hyomora (Hipporhinini), Aphela (Notiomimetini), Rhythirrinus (Rhythirrinini) and Telurus (Cylydrorhinini).…”

“…They are widely distributed in the Southern Hemisphere, with the genus Listronotus also occurrying in North America (Morrone 2011) and fossils known from Antarctica (Ashworth and Kuschel 2003). The tribe was originally proposed by LeConte (1876) for the New World genera Listroderes , Listronotus and Macrops .…”

“…Recently, Oberprieler (2010) transferred Rhigopsidius from Rhythirrinini to Listroderini and reassigned the listroderine genus Telurus to the tribe Cylydrorhinini (Entiminae). According to the last checklist (Morrone 2011), a total of 407 species classified into 36 genera are assigned to Listroderini. Due to all these changes the taxa currently assigned to Listroderini constitute an assemblage that is difficult to characterize, and there is no complete treatment of all the genera.…”

The subtribes and genera of the tribe Listroderini (Coleoptera, Curculionidae, Cyclominae): Phylogenetic analysis with systematic and biogeographical accounts

The phylogenetic relationships of the genera of Listroderini LeConte, 1876 are analyzed based on 58 morphological characters. The genera are grouped in four clades, which are given subtribal status: Macrostyphlina new subtribe (Adioristidius, Amathynetoides, Andesianellus, Macrostyphlus, Nacodius and Puranius), Palaechthina Brinck, 1948 (Anorthorhinus, Gunodes, Haversiella, Inaccodes, Listronotus, Neopachytychius, Palaechthus, Palaechtodes, Steriphus and Tristanodes), Falklandiina new subtribe (Falklandiellus, Falklandiopsis, Falklandius, Gromilus, Lanteriella, Liparogetus, Nestrius and Telurus), and Listroderina (Acroriellus, Acrorius, Acrostomus, Antarctobius, Germainiellus, Hyperoides, Lamiarhinus, Listroderes, Methypora, Philippius, Rupanius and Trachodema). The subtribes are characterized and keys to identify them and their genera are provided. Listroderini have four main biogeographical patterns: Andean (Macrostyphlina), Andean-New Zealand (Falklandiina), Andean-Neotropical-Australian (Listroderina) and Andean-Neotropical-Australian-New Zealand-Nearctic-Tristan da Cunha-Gough islands (Palaechthina). Geographical paralogy, particularly evident in the Subantarctic subregion of the Andean region, suggests that Listroderini are an ancient Gondwanic group, in which several extinction events might have obscured relationships among the areas.

“…One of the authors (CG) discovered Cyclominae associated with mosses in high elevation habitats of Ecuador. These belong to the genus Macrostyphlus Kirsch, 1889 (Listroderini LeConte, 1876, a tribe distributed in the Americas, Australia, New Zealand and Tristan da Cunha [22]). These Macrostyphlus specimens have some morphological resemblance to Dichotrachelus, and mt-Cox1 sequences showed that Dichotrachelus shares more sites in common with Macrostyphlus than with Gronops: D. rudeni, for example, has 667/775 sites in common with Macrostyphlus and 625/775 in common with Gronops, and the translated sequences have 226/258 sites of amino acids in common with Macrostyphlus and 207/258 in common with Gronops.…”

A phylogenetic analysis of the genus Dichotrachelus (Curculionidae: Cyclominae) was carried out, based on a morphological matrix and, for some species, on mitochondrial cytochrome oxidase I sequences. Bayesian Inference, Maximum Likelihood and Maximum Parsimony were implemented and the results were compared. The genus is found to be isolated in the subfamily, not related to the only other Palaearctic tribe (Hipporhinini) and possibly nearer to the south-American genera of Cyclominae of the tribe Listroderini. Among these, Macrostyphlus is also equally associated to mosses as the host plant. In Dichotrachelus, two main clades were recognized, one distributed in the western part of the Mediterranean region (Iberian Peninsula, northern Africa and southern France) and the second distributed in the Alps and Apennines. Within each clade, some differentiated monophyletic subgroups could be identified. An evaluation of the most important characters that led to the phylogenetic reconstruction indicated the male genital sclerite as the most useful structure to characterize the different clades. updated in 2015 [20]. Some additional species of the genus were also included in a more generic Barcode-approach on Swiss Alpine weevils [21].Herein, we propose a phylogenetic analysis for the entire genus Dichotrachelus, based on a morphological database matrix, as well as on mt-Cox1 sequences available for some species, in order to support the main clades (or species groups) and recognize the synapomorphies that define these groups. Available sequences of other Cyclominae were used in a first attempt at recognizing the affinities of Dichotrachelus within Cyclominae. Material and Methods Samples OriginSee Table I in the supplementary materials for a list of the species and specimens used, and for authorship and year of publication of the names. Specimens for molecular analyses were sampled by the authors. The weevils were hand-collected, immediately killed in 95% ethanol and preserved at −20 • C. Attempts to recover complete sequences of other species from dry collection specimens were seldom successful, and usually did not provide any reliable data. For the morphological analysis, samples from Meregalli's collection were used. Almost all species were included in the morphological matrix, except for D. elongatus and D. ulbrichi, species only known from the types, or, for the former, from very few specimens which could not be analysed, and the descriptions of which are insufficiently detailed to permit the scoring of the character states used for the study. Different subspecies of the same species were united with the nominal species, with the exception of D. knechti. This species was classified as a subspecies of D. stierlini in [1], but in the morphological analysis some of the character-states were distinct from those of D. stierlini, hence we have included it in the study. Sequences of the other species of Cyclominae were retrieved from GenBank. Outgroup SelectionThe selection of an outgroup proved particularly complex, since, a...
