Abstract: A large-scale phylogenetic study is presented for Cucujoidea (Coleoptera), a diverse superfamily of beetles that historically has been taxonomically difficult. This study is the most comprehensive analysis of cucujoid taxa to date, with DNA sequence data sampled from eight genes (four nuclear, four mitochondrial) for 384 coleopteran taxa, including exemplars of 35 (of 37) families and 289 genera of Cucujoidea. Maximum-likelihood analyses of these data present many significant relationships, some proposed previously and some novel. Tenebrionoidea and Lymexyloidea are recovered together and Cleroidea forms the sister group to this clade. Chrysomeloidea and Curculionoidea are recovered as sister taxa and this clade (Phytophaga) forms the sister group to the core Cucujoidea (Cucujoidea s.n.). The nitidulid series is recovered as the earliest-diverging core cucujoid lineage, although the earliest divergences among core Cucujoidea are only weakly supported. The cerylonid series (CS) is recovered as monophyletic and is supported as a major Cucujiform clade, sister group to the remaining superfamilies of Cucujiformia. Currently recognized taxa that were not recovered as monophyletic include Cucujoidea, Endomychidae, Cerylonidae and Bothrideridae. Biphyllidae and Byturidae were recovered in Cleroidea. The remaining Cucujoidea were recovered in two disparate major clades: one comprising the nitidulid series + erotylid series + Boganiidae and Hobartiidae + cucujid series, and the other comprising the cerylonid series. Propalticidae are recovered within Laemophloeidae. The cerylonid series includes two major clades, the bothriderid group and the coccinellid group. Akalyptoischiidae are recovered as a separate clade from Latridiidae. Eupsilobiinae are recovered as the sister taxon to Coccinellidae. In light of these findings, many formal changes to cucujiform beetle classification are proposed. Biphyllidae and Byturidae are transferred to Cleroidea. The cerylonid series is formally recognized as a new superfamily, Coccinelloidea stat.n. Current subfamilies elevated (or re-elevated) to family status include: Murmidiidae stat.n., Teredidae stat.n., Euxestidae stat.n., Anamorphidae stat.rev., Eupsilobiidae stat.n., and Mycetaeidae stat.n. The following taxa are redefined and characterized: Cleroidea s.n., Cucujoidea s.n., Cerylonidae s.n., Bothrideridae s.n., Endomychidae s.n. A new subfamily, Cyclotominae stat.n., is described. Stenotarsinae syn.n. is formally subsumed within a new concept of Endomychinae s.n.
TL;DR: Evidence is provided that the Lithuanian coleopteran fauna has yet to be completely investigated and it is estimated that approximately 28 % of beetle species remain undiscovered in Lithuania.
Abstract: This paper presents the first complete and updated list of all 3597 species of beetles (Insecta: Coleoptera) belonging to 92 familiesfound and published in Lithuania until 2011, with comments also provided on the main systematic and nomenclatural changes since the last monographic treatment in two volumes (Pileckis and Monsevicius 1995, 1997). The introductory section provides a general overview of the main features of the territory of Lithuania, the origins and formation of the beetle fauna and their conservation, the faunistic investigations in Lithuania to date revealing the most important stages of the faunistic research process with reference to the most prominent scientists, an overview of their work, and their contribution to Lithuanian coleopteran faunal research.Species recorded in Lithuania by some authors without reliable evidence and requiring further confirmation with new data are presented in a separate list, consisting of 183 species. For the first time, analysis of errors in works of Lithuanian authors concerning data on coleopteran fauna has been conducted and these errors have been corrected. All available published and Internet sources on beetles found in Lithuania have been considered in the current study. Over 630 literature sources on species composition of beetles, their distribution in Lithuania and neighbouring countries, and taxonomic revisions and changes are reviewed and cited. An alphabetical list of these literature sources is presented. After revision of public beetle collections in Lithuania, the authors propose to remove 43 species from the beetle species list of the country on the grounds, that they have been wrongly identified or published by mistake. For reasons of clarity, 19 previously noted but later excluded species are included in the current checklist with comments. Based on faunal data from neighbouring countries, species expected to occur in Lithuania are matnioned. In total 1390 species are attributed to this category and data on their distribution in neighbouring countries is presented. Completion of this study provides evidence that the Lithuanian coleopteran fauna has yet to be completely investigated and it is estimated that approximately 28 % of beetle species remain undiscovered in Lithuania. More than 85% of beetle species expected for Lithuania have been found in the following families: Cerylonidae, Geotrupidae, Haliplidae, Kateridae, Lycidae, Lucanidae, Mycetophagidae, Scarabaeidae and Silphidae. In families with few species such as Alexiidae, Boridae, Byturidae, Dascilidae, Drilidae, Eucinetidae, Lampyridae, Lymexilidae, Megalopodidae, Nemonychidae, Nosodendridae, Noteridae, Orsodacnidae, Pyrochroidae, Pythidae, Psephenidae, Rhysodidae, Sphaeritidae, Sphaeriusidae, Sphindidae, Stenotrahelidae and Trogidae, all possible species have already been discovered. However in some beetle families such as Aderidae, Bothrideridae, Eucnemidae, Laemoploeidae, Mordellidae, Ptiliidae, Scraptidae and Throscidae less than 50% of all possible species are known. At present the beetle species recorded in Lithuania belong to 92 families, with species from 9 other families such as Agyrtidae, Biphylidae, Deradontidae, Mycteridae, Ochodaeidae, Phleophilidae, Phloeostichidae, Prostomidae, Trachypachidae are expected to be found.A bibliography and a index of subfamily and genus levels are provided. The information published in the monograph will serve to further faunistic and distribution research of beetles and will help to avoid confusion in the identificatation of coleopteran fauna of Lithuania.
TL;DR: A phylogenetic study based on 18S and 28S rDNA for 16 outgroup taxa and 61 C.S. ingroup taxa of the Cerylonid Series confirms the paraphyly of Cucujoidea with respect to Tenebrionoidea and confirms the monophyly of the corylophid subfamily Corylophinae.
TL;DR: The ultimate goal is to assemble a complete list of available Coleoptera family-group names published up to the end of 2010 (including information about their spelling, author, year of publication, and type genus).
Abstract: Changes to the treatment of Coleoptera family-group names published by Bouchard et al. (2011) are given. These include necessary additions and corrections based on much-appreciated suggestions from our colleagues, as well as our own research. Our ultimate goal is to assemble a complete list of available Coleoptera family-group names published up to the end of 2010 (including information about their spelling, author, year of publication, and type genus). The following 59 available Coleoptera family-group names are based on type genera not included in Bouchard et al. (2011): Prothydrinae Guignot, 1954, Aulonogyrini Ochs, 1953 (Gyrinidae); Pogonostomini Mandl 1954, Merismoderini Wasmann, 1929, †Escheriidae Kolbe, 1880 (Carabidae); Timarchopsinae Wang, Ponomarenko & Zhang, 2010 (Coptoclavidae); Stictocraniini Jakobson, 1914 (Staphylinidae); Cylindrocaulini Zang, 1905, Kaupiolinae Zang, 1905 (Passalidae); Phaeochroinae Kolbe, 1912 (Hybosoridae); Anthypnidae Chalande, 1884 (Glaphyridae); Comophorini Britton, 1957, Comophini Britton, 1978, Chasmidae Streubel, 1846, Mimelidae Theobald, 1882, Rhepsimidae Streubel, 1846, Ometidae Streubel, 1846, Jumnidae Burmeister, 1842, Evambateidae Gistel, 1856 (Scarabaeidae); Protelmidae Jeannel, 1950 (Byrrhoidea); Pseudeucinetini Csiki, 1924 (Limnichidae); Xylotrogidae Schonfeldt, 1887 (Bostrichidae); †Mesernobiinae Engel, 2010, Fabrasiinae Lawrence & Reichardt, 1966 (Ptinidae); Arhinopini Kirejtshuk & Bouchard, 2018 (Nitidulidae); Hypodacninae Dajoz, 1976, Ceuthocera Mannerheim, 1852 (Cerylonidae); Symbiotinae Joy, 1932 (Endomychidae); Cheilomenini Schilder & Schilder, 1928, Veraniini Schilder & Schilder, 1928 (Coccinellidae); Ennearthroninae Chujo, 1939 (Ciidae); Curtimordini Odnosum, 2010, Mordellochroini Odnosum, 2010 (Mordellidae); Chanopterinae Borchmann, 1915 (Promecheilidae); Heptaphyllini Prudhomme de Borre, 1886, Olocratarii Baudi di Selve, 1875, Opatrinaires Mulsant & Rey, 1853, Telacianae Poey, 1854, Ancylopominae Pascoe, 1871 (Tenebrionidae); Oxycopiini Arnett, 1984 (Oedemeridae); Eutrypteidae Gistel, 1856 (Mycteridae); Pogonocerinae Iablokoff-Khnzorian, 1985 (Pyrochroidae); Amblyderini Desbrochers des Loges, 1899 (Anthicidae); Trotommideini Pic, 1903 (Scraptiidae); Acmaeopsini Della Beffa, 1915, Trigonarthrini Villiers, 1984, Eunidiini Teocchi, Sudre & Jiroux, 2010 (Cerambycidae); Macropleini Lopatin, 1977, Stenopodiides Horn, 1883, Microrhopalides Horn, 1883, Colaphidae Siegel, 1866, Lexiphanini Wilcox, 1954 (Chrysomelidae); †Medmetrioxenoidesini Legalov, 2010, †Megametrioxenoidesini Legalov, 2010 (Nemonychidae); Myrmecinae Tanner, 1966, Tapinotinae Joy, 1932, Acallinae Joy, 1932, Cycloderini Hoffmann, 1950, Sthereini Hatch, 1971 (Curculionidae). The following 21 family-group names, listed as unavailable in Bouchard et al. (2011), are determined to be available: Eohomopterinae Wasmann, 1929 (Carabidae); Prosopocoilini Benesh, 1960, Pseudodorcini Benesh, 1960, Rhyssonotini Benesh, 1960 (Lucanidae); Galbini Beaulieu, 1919 (Eucnemidae); Troglopates Mulsant & Rey, 1867 (Melyridae); Hippodamiini Weise, 1885 (Coccinellidae); Micrositates Mulsant & Rey, 1854, Heliopathaires Mulsant & Rey, 1854 (Tenebrionidae); Hypasclerini Arnett, 1984; Oxaciini Arnett, 1984 (Oedemeridae); Stilpnonotinae Borchmann, 1936 (Mycteridae); Trogocryptinae Lawrence, 1991 (Salpingidae); Grammopterini Della Beffa, 1915, Aedilinae Perrier, 1893, Anaesthetinae Perrier, 1893 (Cerambycidae); Physonotitae Spaeth, 1942, Octotomides Horn, 1883 (Chrysomelidae); Sympiezopinorum Faust, 1886, Sueinae Murayama, 1959, Eccoptopterini Kalshoven, 1959 (Curculionidae). The following names were proposed as new without reference to family-group names based on the same type genus which had been made available at an earlier date: Dineutini Ochs, 1926 (Gyrinidae); Odonteini Shokhin, 2007 (Geotrupidae); Fornaxini Cobos, 1965 (Eucnemidae); Auletobiina Legalov, 2001 (Attelabidae). The priority of several family-group names, listed as valid in Bouchard et al. (2011), is affected by recent bibliographic discoveries or new nomenclatural interpretations. †Necronectinae Ponomarenko, 1977 is treated as permanently invalid and replaced with †Timarchopsinae Wang, Ponomarenko & Zhang, 2010 (Coptoclavidae); Agathidiini Westwood, 1838 is replaced by the older name Anisotomini Horaninow, 1834 (Staphylinidae); Cyrtoscydmini Schaufuss, 1889 is replaced by the older name Stenichnini Fauvel, 1885 (Staphylinidae); Eremazinae Iablokoff-Khnzorian, 1977 is treated as unavailable and replaced with Eremazinae Stebnicka, 1977 (Scarabaeidae); Coryphocerina Burmeister, 1842 is replaced by the older name Rhomborhinina Westwood, 1842 (Scarabaeidae); Eudysantina Bouchard, Lawrence, Davies & Newton, 2005 is replaced by the older name Dysantina Gebien, 1922 which is not permanently invalid (Tenebrionidae). The names Macraulacinae/-ini Fleutiaux, 1923 (Eucnemidae), Anamorphinae Strohecker, 1953 (Endomychidae), Pachycnemina Laporte, 1840 (Scarabaeidae), Thaumastodinae Champion, 1924 (Limnichidae), Eudicronychinae Girard, 1971 (Elateridae), Trogoxylini Lesne, 1921 (Bostrichidae), Laemophloeidae Ganglbauer, 1899 (Laemophloeidae); Ancitini Aurivillius, 1917 (Cerambycidae) and Tropiphorini Marseul, 1863 (Curculionidae) are threatened by the discovery of older names; Reversal of Precedence (ICZN 1999: Art. 23.9) or an application to the International Commission on Zoological Nomenclature will be necessary to retain usage of the younger synonyms. Reversal of Precedence is used herein to qualify the following family-group names as nomina protecta: Murmidiinae Jacquelin du Val, 1858 (Cerylonidae) and Chalepini Weise, 1910 (Chrysomelidae). The following 17 Coleoptera family-group names (some of which are used as valid) are homonyms of other family-group names in zoology, these cases must be referred to the Commission for a ruling to remove the homonymy: Catiniidae Ponomarenko, 1968 (Catiniidae); Homopterinae Wasmann, 1920, Glyptini Horn, 1881 (Carabidae); Tychini Raffray, 1904, Ocypodina Hatch, 1957 (Staphylinidae); Gonatinae Kuwert, 1891 (Passalidae); Aplonychidae Burmeister, 1855 (Scarabaeidae); Microchaetini Paulus, 1973 (Byrrhidae); Epiphanini Muona, 1993 (Eucnemidae); Limoniina Jakobson, 1913 (Elateridae); Ichthyurini Champion, 1915 (Cantharidae); Decamerinae Crowson, 1964 (Trogossitidae); Trichodidae Streubel, 1839 (Cleridae); Monocorynini Miyatake, 1988 (Coccinellidae); Gastrophysina Kippenberg, 2010, Chorinini Weise, 1923 (Chrysomelidae); Meconemini Pierce, 1930 (Anthribidae). The following new substitute names are proposed: Phoroschizus (to replace Schizophorus Ponomarenko, 1968) and Phoroschizidae (to replace Schizophoridae Ponomarenko, 1968); Mesostyloides (to replace Mesostylus Faust, 1894) and Mesostyloidini (to replace Mesostylini Reitter, 1913). The following new genus-group name synonyms are proposed [valid names in square brackets]: Plocastes Gistel, 1856 [Aesalus Fabricius, 1801] (Lucanidae); Evambates Gistel, 1856 [Trichius Fabricius, 1775] (Scarabaeidae); Homoeoplastus Gistel, 1856 [Byturus Latreille, 1797] (Byturidae). Two type genera previously treated as preoccupied and invalid, Heteroscelis Latreille, 1828 and Dysantes Pascoe, 1869 (Tenebrionidae), are determined to be senior homonyms based on bibliographical research. While Dysantes is treated as valid here, Reversal of Precedence (ICZN 1999: Art. 23.9) is used to conserve usage of Anomalipus Guerin-Meneville, 1831 over Heteroscelis.
