A complete and updated list of 1,066 species and subspecies of the superfamily Curculionoidea recorded from Poland until the end of 2017 is provided, including over 290 comments on all taxonomic, nomenclatural and faunistic changes made since the first edition of the checklist published in 2005. An additional 37 species in the list are considered as erroneously recorded and excluded from the fauna of Poland. An update of the index of genera and subgenera, together with their type species, is provided separately. The following two new synonyms are recognised: Bruchela rufipes nigritarsis (Reitter, 1916) = B. rufipes rufipes (Olivier, 1790) (Anthribidae: Urodontinae), Otiorhynchus proximus iteratus Magnano, 2001 = O. proximus proximus Stierlin, 1861 (Curculionidae: Entiminae). Six species are resurrected from synonymy with the species given in parentheses: Squamapion serpyllicola (Wencker) (S. minutissimum (Rosenhauer)), Polydrusus thalassinus Gyllenhal (P. formosus (Mayer)), Phyllobius vespertinus (Fabricius) (Ph. pyri (L.)), Microplontus melanostigma (Marsham) (M. rugulosus (Herbst)), Otiorhynchus smreczynskii Cmoluch (O. rotundus Marseul), Romualdius angustisetulus (Hansen) (R. scaber (Linnaeus)). Phyllobius fessus Boheman is replaced in the list with Ph. jacobsoni Smirnov due to the former misidentification of Polish specimens. Brachysomus strawinskii Cmoluch is transferred from subgenus Hippomias to Brachysomus s. str. Eleven new weevil species have been discovered in Poland since 2005, including the still unpublished records of Pachycerus madidus (Olivier). The occurrence in Poland of four species, having hitherto only uncertain old records, has been confirmed with recent findings. The number of dubious species in Poland increased to 27 after the inflow of uncertain data in the literature and probable cases of extinction.

A second species of the genus Zoutpansbergia Koch, 1956 (Z. schoemani sp. nov.) is described from the Limpopo Province in South Africa. Morphology of female terminalia of the studied genus is described for the first time. Systematic position of Zoutpansbergia within the subtribe Melambiina is briefly discussed. Lectotype for Zoutpansbergia serricostata Koch, 1956 is designated, in order to fix the taxonomic status of this species.

Here, we review the species Cratomorphus cossyphinus (Perty, 1830) after study of the holotype, 24 adults and nine immature stages deposited in five collections. The species is found throughout South America, inhabiting wetlands. Larva, pupa and female are described for the first time, and the male is redescribed and illustrated, with an emphasis on sexual dimorphism. The larva is considered semiaquatic, condition also known in related Cratomorphini taxa, found on vegetation either marginal or over sand islets on marshes. Sexually dimorphism was more pronounced in the size and shape of the following structures: frons, antenna, eyes, hypomeron, hind wing, lantern on the sternum VI, sternum VIII and pygidium. Interestingly enough, most of the aforementioned features are involved with mate finding. We also report remarkable multiple spermathecae in the female, unprecedented for the genus and for the family as well. Finally, we provide illustrations and diagnoses for all stages, and an updated distribution map for the species for South America, reporting C. cossyphinus from Venezuela and Suriname to Southern Brazil.

This paper presents a further step in a revision of the fossil family Orthophlebiidae. A new fossil subfamily, Gigaphlebiinae subfam. nov., and two new genera, Gigaphlebia gen. nov. and Longiphlebia gen. nov., are established within Orthophlebiidae. The new subfamily comprises species characterized by a large size, ninebranched (exceptionally eight-branched) radial sector in both wings, and medial sector with six branches in the fore- and five in the hindwing. Four species, Gigaphlebia grandis comb. nov., G. palmaris comb. nov., G. riccardii comb. nov., and Longiphlebia stigmosa comb. nov. were transferred from genus Orthophlebia and Mesopanorpa. The diagnoses of newly established taxa are presented, all transferred species are redescribed and refigured. The significance of orthophlebiid taxonomy in the phylogeny of the Panorpoidea is discussed.

Description of a new species of the genus Mesotipula Handlirsch, 1939 (Limoniidae, Diptera) from the Lower Jurassic of Dumbleton, England is provided. This is the first representative of this genus from the Lower Jurassic of England.

The host-parasite associations between bats and chiggers are re-traced; the checklist of reported pair-wise combinations contains records originating from all zoogeographical regions. The data on parasitism of 397 nominal species of Trombiculidae (c. 12% of all species) on 301 bat species and subspecies (c. 30% of described species of Chiroptera), previously scattered around the literature, are compiled.

Glaciers and ice sheets are considered a biome with unique organism assemblages. Tardigrada (water bears) are micrometazoans that play the function of apex consumers on glaciers. Cryoconite samples with the dark-pigmented tardigrade Cryoconicus gen. nov. kaczmareki sp. nov. were collected from four locations on glaciers in China and Kyrgyzstan. The erection of the new genus is based on a unique combination of morphological traits as well as on phylogenetic analyses. The analysis of COI sequences in the new species revealed high genetic differentiation with 9 haplotypes shared among 13 sequenced individuals from three sequenced populations. There was no apparent geographic structure in COI haplotype diversity, which might indicate effective dispersal abilities of the new species. A recovery of numerous live individuals from a sample that was frozen for 11 years suggests high survival rates in the natural environment. The ability to withstand low temperatures, combined with dark pigmentation that is hypothesised to protect from intense UV radiation, could explain how the new taxon is able to dwell in an extreme glacial habitat. We also found that a rare mountain tardigrade Ramazzottius cataphractus (Maucci, 1974) is morphologically similar to the new species, therefore we propose to transfer it to the new genus. Our study indicates that glacier invertebrate fauna is still poorly known and requires intense research.
