The first molecular phylogeny of Blosyrini weevils (Coleoptera: Curculionidae: Entiminae) rejects monophyly of the tribe and documents a new Asian clade with the highest diversity in the Hengduan Mountains.

This paper targets diversity and phylogeny of the Old World weevil tribe Blosyrini and, specifically, its Asian members. Phylogenetic analysis of one mitochondrial and two nuclear DNA fragments from 78 terminals reveals that Blosyrini weevils, although monophyletic in Asia, in Madagascar, and in continental Africa, do not share a unique common ancestor. Instead, they form a strongly supported clade together with representatives of two other tribes of broad-nosed weevils: Cneorhinini and Dermatodini.

Phylogenetic placement of a new Melanophilharmostes Paulian, 1968 pill scarab (Coleoptera: Hybosoridae: Ceratocanthinae) from Cameroon: molecular results decipher misleading morphology.

This study targets two specimens of a morphologically highly unusual pill scarab from Cameroon. The original morphology-inspired hypothesis that these beetles represent a new genus is refuted. Instead, a phylogenetic analysis of 90 terminals and 3231 aligned DNA positions linked both specimens with the Afrotropical genus Melanophilharmostes Paulian, 1968.

The first molecular phylogeny of the weevil subfamily Lixinae (Coleoptera: Curculionidae) casts doubts on the monophyly of its tribes.

This paper targets the nearly cosmopolitan weevil subfamily Lixinae. A phylogenetic analysis of one mitochondrial and two nuclear DNA fragments obtained from 87 Lixinae and 49 outgroup terminals strongly supports the monophyly of the subfamily. The molytine tribe Mecysolobini is the likeliest sister group of Lixinae; adults of both taxa share the likely synapomorphic condition of the greatly shortened labial palpi.

Endogean beetles (Coleoptera) of Madagascar: deep soil sampling and illustrated overview.

This study addresses the diversity of deep soil beetles on the old continental island of Madagascar. We highlight Coleoptera as the only order of insects repeatedly occupying the deep soil (=endogean) habitat. We describe and illustrate soil flotation technique used during our fieldwork in Madagascar in December 2019.

Late Miocene eastwards transatlantic dispersal of flightless anchonine weevils (Coleoptera: Curculionidae: Molytinae).

The weevil genera Aethiopacorep Voisin and Titilayo Cristóvão Lyal are the only native African members of the nearly pantropical and poorly known tribe Anchonini. All Anchonini are flightless, a trait likely limiting dispersal, yet these weevils are found on both sides of the Atlantic Ocean. A phylogenetic analysis of 79 terminals and 3248 aligned positions from one mitochondrial and two nuclear ribosomal fragments supports a clade of West African Anchonini nested within American Anchonini.

Tazarcus, a new phylogenetically unplaced genus of two flightless weevils with metapleural ridge from the Eastern Arc Mountains, Tanzania (Coleoptera: Curculionidae: Molytinae).

This paper reports new flightless forest litter weevils discovered in Tanzania. They are classified into two species of the genus Tazarcus gen. nov.

Allaeotes niger, a weevil introduced to Cuba and the only known New World Stromboscerini (Coleoptera: Curculionidae: Dryophthorinae).

Allaeotes niger He, Zhang and Pelsue, a weevil hitherto known only from the type series collected in China, is for the first time reported from Cuba. In addition to three historical Cuban specimens, approximately one hundred adults were observed in 2018 under bark of fallen logs at a plantation of (likely non-native) pines in westernmost Pinar del Río province. This is the only New World record of a member of the monophyletic core of the tribe Stromboscerini, otherwise distributed in a triangle delimited by Japan, Sri Lanka and northern Australia (plus a single mysterious record from Uganda).

Twenty more new species of Agrilus (Coleoptera: Buprestidae: Agrilinae) from the Oriental region.

Twenty new species of Agrilus jewel beetles from the Oriental region are described and illustrated: Agrilus cicadelloides sp. nov. (Malaysia: Sarawak); A.

Dryophthorinae weevils (Coleoptera: Curculionidae) of the forest floor in Southeast Asia: DNA analysis of two new Nephius from Vietnam and Taiwan suggests non-monophyly of Stromboscerini.

The weevil genus Nephius Pascoe is for the first time reported from Vietnam (N. argus sp. nov.

Discovery of Lymantini weevils (Coleoptera: Curculionidae: Molytinae) outside the Americas: Devernodes, a new genus for five new species from Southeast Asia.

This paper reports a new weevil genus Devernodes gen. n. established for five new species from Southeast Asia: D.

Dryophthorinae weevils (Coleoptera: Curculionidae) of the forest floor in Southeast Asia: illustrated overview of nominal Stromboscerini genera.

All 13 Recent genera currently assigned to the tribe Stromboscerini are studied and illustrated based mainly on the type specimens of the type species. Nominal monotypic genus Parasynommatus Voss, 1956 from New Guinea is herein transferred to Cossoninae incertae sedis. The genus Nephius is notably dissimilar to the rest of the tribe and perhaps renders it paraphyletic.

Both non-type species of Molytophilus (Coleoptera: Curculionidae: Molytinae) are transferred to Oreoscotus.

Type specimens of all three nominal species of the East African genus Molytophilus Hartmann are studied and illustrated. The genus is taxonomically restricted to include only the type species M. carinatus Hartman known from two collecting events in Tanzania and Somalia.

Twenty new species of Agrilus (Coleoptera: Buprestidae: Agrilinae) from the Oriental Region.

Twenty new Agrilus species from the Oriental Region are described and illustrated: A. aramis sp. nov.

Cleonini (Coleoptera: Curculionidae: Lixinae) are monophyletic and flightless: tribe overview, rampant adult homoplasy and illustrated global diversity.

We summarize knowledge of the weevil tribe Cleonini worldwide, including its monophyly, relationships, distribution, biology, immature stages, economic significance and paleontology. We score adult morphological characters for 79 of a total of 96 extant genus-group Cleonini taxa considered valid to date. The resulting matrix contains 121 parsimoniously informative characters scored for 145 ingroup (Cleonini) and 29 outgroup terminals.

Flightless (Coleoptera: Curculionidae: Entiminae) in Southwest China survive the Holocene trapped on mountaintops: new species, unknown phylogeny and clogging taxonomy.

This paper reports the first discovery of the weevil genus Catapionus in Southwest China. Eighteen specimens of C. mopsus sp.

Flightless litter-dwelling Cotasterosoma (Coleoptera: Curculionidae: Cossoninae) found outside of Japan, with mtDNA phylogeography of a new species from Southwest China.

The herein reported beetles (Figs 1, 2) were repeatedly sampled by the first author since 2008 by sifting leaf litter in two forested localities in Southwest China: Cang Shan Mountain Range in Yunnan and Mount Emei in Sichuan (Fig. 3). The specimens' characteristic appearance and edaphic way of life were consistent with those of various members of the subfamily Cossoninae (Morimoto 1973, 1993, 1995), although a more precise taxonomic assignment remained elusive.

The genus Prothrombosternus (Coleoptera: Curculionidae: Molytinae) rediscovered: a male from Rubeho Mountains, Tanzania.

A male specimen of the monotypic weevil genus, Prothrombosternus Voss, 1965, so far known on the basis of only five syntypes from Mt. Meru and Mt. Hanang, Tanzania, is reported from the Rubeho Mountains, Tanzania.

Flightless Notaris (Coleoptera: Curculionidae: Brachycerinae: Erirhinini) in Southwest China: monophyly, mtDNA phylogeography and evolution of habitat associations.

This paper reports the recent discovery of flightless populations of weevils of the genus Notaris in Yunnan and Sichuan provinces of China. Specimens were found in the middle or high altitude mountains (2440-4195 m), by either sifting leaf litter in the deciduous forest and among alpine Rhododendron shrubs, or by turning rocks in the alpine zone. These finds extend southwards the Asian range of this Holarctic genus and report its highest altitudinal records.

Undetected for a century: Palaearctic Agrilus ribesi Schaefer (Coleoptera: Buprestidae) on currant in North America, with adult morphology, larval biology and DNA barcode.

We report the Eurasian species Agrilus ribesi Schaefer, 1946, for the first time from North America and propose that the damage to currants (Ribes spp.) in Ontario prior to 1940 and ascribed to A. cuprescens were caused by this species.

First record and five new species of Xylographellini (Coleoptera: Ciidae) from China, with online DNA barcode library of the family.

We report the first record of the beetle tribe Xylographellini (Ciidae) from the continental Palaearctic Region, represented by five new species discovered in Yunnan and Sichuan provinces, China: Scolytocis danae sp. nov., Syncosmetus euryale sp.

DNA barcoding and regional diversity of understudied Micropeplinae (Coleoptera: Staphylinidae) in Southwest China: phylogenetic implications and a new Micropeplus from Mount Emei.

Extensive litter sampling at eight forested localities in Yunnan and Sichuan detected 381 specimens of Micropeplinae rove beetles. DNA barcoding data from 85 representative specimens were analysed to delimit species and infer their relationships. Statistical methods were implemented to assess regional species diversity of understudied Micropeplinae.

First record of Otibazo (Coleoptera: Curculionidae: Molytinae) outside of Japan, with description of a new species from Vietnam.

A new species of wingless leaf litter weevil, Otibazo polyphemus sp. n., is described from Tam Dao, northern Vietnam.

A new concept of Absoloniella (=Ruffodytes syn. n.) for five blind Mediterranean species (Coleoptera: Brachyceridae: Erirhininae).

A hundred year-long taxonomic ambiguity surrounding two mysterious species originally described as Caulomorphus reitteri Müller, 1912 and Absoloniella cylindrica Formánek, 1913, both known from single specimens believed to be lost, is resolved. This is achieved by designation of their neotypes based on the same specimen collected together, and considered conspecific, with the holotype of Ruffodytes hellenicus Osella, 1973, the latter the type of the genus Ruffodytes Osella, 1973. This action triggers the following nomenclatorial and taxonomic changes: (1) the generic name Ruffodytes Osella, 1973 syn.

DNA barcode and phylogeography of six new high altitude wingless Niphadomimus (Coleoptera: Curculionidae: Molytinae) from Southwest China.

The genus Niphadomimus Zherikhin, 1987 is taxonomically revised herein. In addition to the two recorded Nepalese species, N. nigriventris Zherikhin and N.

A new species of Dexoris (Coleoptera: Lycidae) and parallel evolution of brachyptery in the soft-bodied elateroid beetles.
