Olemehlia krali,a new genus and species of Ripidiinae from Baltic amber (Coleoptera: Ripiphoridae)

A new genus and species, Olemehlia krali n. g. & n. sp. (Coleoptera: Ripiphoridae: Ripidiinae), is described from Baltic amber. The newly described genus is compared with all known fossil and extant closely related genera of the subfamily Ripidiinae. It is characterised by the following combination of characters: antennae consisting of 10 antennomeres, with scape, pedicel, and antennomere 3 simple and antennomeres 4–10 uniflabellate, mouthparts reduced to a small single unpaired tubercle, postocular ommatidia absent, pronotum trapezoid without grooves or impressions, elytra without white apical spots, tarsal formula 5–5–4, hind tarsomere I shorter than three remaining combined. Diversity of Ripiphoridae in Baltic amber is discussed; key to Ripidiinae genera from Baltic amber is provided.     

A new species of Diochus from Baltic amber (Coleoptera, Staphylinidae, Diochini)

The first fossil of the staphylinine tribe Diochini Casey is described and figured from an inclusion in mid-Eocene (Lutetian) Baltic amber. Diochus electrussp. n. is distinguished from its congeners and the diversity of rove beetles (Staphylinidae s.l.) is summarized briefly.     

A new genus and species of timber beetle (Coleoptera: Lymexylidae) from the Baltic amber

Ponomarenkylon alexandri gen. et sp. nov. (Melittommatinae) from the Late Eocene Baltic amber is described. The long filiform antennae and the apparent absence of sensillary organs, which are frequently present on modified maxillary palps in other lymexylids, are evidence of the primitive state of the new genus.     

A new weevil genus of the tribe Metrioxenini (Coleoptera: Belidae) in Eocene Baltic amber

A new genus, Succinometrioxena n. gen., and a new species, S. poinari n. sp. (Metrioxenini: Oxycoryninae), are described from Baltic amber. This new genus resembles the recent genus Wallacexena Legalov, 2009 but differs from it by the frons with horn-like tubercles on either side, the absence of a middle pronotal carina, teeth on the side of the pronotum, the anterior margin of the pronotum lacking teeth and two long carinae on the elytra. From the fossil genus Paltorhynchus Scudder, 1893 the present fossil differs by possessing a frons with horn-like tubercles on either side, the absence of a middle pronotal carina, teeth on the sides of the pronotum, two long carinae on the elytra and short temples. From the fossil genus Archimetrioxena Voss, 1953, the new genus differs by the frons with horn-like tubercles on either side, the absence of the two truncated elytral carinae, the sides of the pronotum with teeth, short temples and a larger body size.     

Three littoral Athetini (Coleoptera: Staphylinidae: Aleocharinae) species new to Korea

Three littoral Athetini species –Adota magnipennis (Bernhauer), Atheta ririkoae Sawada and Atheta tokiokai (Sawada) – are reported for the first time in Korea. Diagnoses, illustrations of the habitus and line drawings of diagnostic characters are provided.     

New genus and species of broad-nosed weevils from Baltic amber and notes on fossils of the subfamily Entiminae (Coleoptera, Curculionidae)

Arostropsis groehnigen. et sp. n. is described from Baltic amber and temporarily placed in the tribe Naupactini. It differs from all recent Naupactini genera with open corbels by very short and flattened scape, distinct lateral carina of the pronotum and elytra, and the rostrum distinctly narrower than the head capsule. The shape of head in the extinct genus is somewhat similar to that of the extant Naupactini genera with enclosed corbels (Platyomus Sahlberg, 1823 and Aptolemus Schoenherr, 1842), but differs in the slender body, open corbels, very short antennal scape and epifrons without a median sulcus (only a longitudinal depression is slightly visible). It is also similar to the Tanymecine genus Pandeleteius Schoenherr, 1834 in general appearance, but distinct by the straight anterior edge of the pronotum, lack of postocular spurs, lobes, and vibrissae, a slightly sloping elytral declivity, lateral ridges on the pronotum, subflattened antennal scape, elongate rostrum, and sparsely setose epistome. A new synonymy of the generic names Protonaupactus Zherikhin, 1971 and Sucinophyllobius Wanat & Borowiec, 1986, syn. n., is established. The Madagascan genus Corecaulus Fairmaire, 1903 is transferred from the tribe Naupactini to the Brachyderini because of its connate claws and the similarity in chaetotaxy of the epistomal area with African and Madagascar Brachyderini genera. A key to the identification of known Baltic amber genera of Entiminae is proposed. A checklist of the prepleistocene fossil Entiminae, based on V.V. Zherikhin's data, with remarks and corrections, is presented.     

Morphogenia: a new genus of the Neotropical tribe Jubini (Coleoptera,Staphylinidae, Pselaphinae) from the Brazilian Amazon

A new genus and species of the large Neotropical pselaphine tribe Jubini is described from Manaus, Brazil, based on material preserved in the Natural History Museum, London. Morphogenia struhligen. et sp. n. represents the possible sister taxon of the abundant and speciose genus Barrojuba Park, sharing with it the putatively derived condition of anterolaterally shifted vertexal foveae, producing a smoothly convex vertex devoid of fovea or sulci. However, unlike Barrojuba, Morphogenia retains a plesiomorphic antebasal sulcus on the pronotum in both sexes, and additionally lacks elaborate abdominal fovea-like pockets and teeth on the lateral margins of the pronotum that are typical of Barrojuba. The genus is also unusual among jubine genera in lacking the characteristic V- or Y-shaped gular carina. In contrast to the commonly-collected Barrojuba, specimens of Morphogenia are absent in extensive jubine collections housed in museums in the United States, indicating that the new taxon may be relatively scarce or localised.     

Molecular phylogeny of the beetle tribe Oxypodini (Coleoptera: Staphylinidae: Aleocharinae)

This is the first study to comprehensively address the phylogeny of the tribe Oxypodini Thomson and its phylogenetic relationships to other tribes within the staphylinid subfamily Aleocharinae. Using the hitherto largest molecular dataset of Aleocharinae comprising of 4599 bp for representatives of 22 tribes, the Oxypodini are recovered as non‐monophyletic. Members of the tribe belong to three distantly related lineages within the Aleocharinae: (i) the Amarochara group as sister clade to the tribe Aleocharini, (ii) the subtribe Tachyusina within a clade that also includes the tribes Athetini and Hygronomini, (iii) all other Oxypodini in a clade that also includes the tribes Placusini, Hoplandriini and Liparocephalini. Based on the inferred phylogeny, five subtribes of the Oxypodini are recognized: Dinardina Mulsant & Rey, Meoticina Seevers, Microglottina Fenyes, Oxypodina Thomson and Phloeoporina Thomson. The following changes in the classification of the Aleocharinae are proposed: (i) Amarochara Thomson is removed from the Oxypodini and placed in the tribe Aleocharini; (ii) the subtribe Taxicerina Lohse of the Athetini is reinstated as tribe Taxicerini to include Discerota Mulsant & Rey, Halobrecta Thomson (both removed from the Oxypodini) and Taxicera Mulsant & Rey; (iii) the subtribe Tachyusina Thomson is excluded from the Oxypodini and provisionally treated as tribe Tachyusini; (iv) the oxypodine subtribe name Blepharhymenina Klimaszewski & Peck is placed in synonymy with the subtribe name Dinardina Mulsant & Rey.     

Three new species of the myrmecophilous genus Doryloxenus from China (Coleoptera,Staphylinidae, Aleocharinae)

Three new species of the pygostenine genus Doryloxenus Wasmann, viz., Doryloxenus aenictophilus sp. n. (from Zhejiang), Doryloxenus tangliangi sp. n. (from Zhejiang), and Doryloxenus songzhigaoi sp. n. (from Yunnan), are described, illustrated and distinguished from the Asian congeners. An identification key to the Chinese species is given.     

A new genus and species of Dictyopharidae (Homoptera) from Rovno and Baltic amber based on nymphs

Alicodoxa rasnitsynigen. et sp. n. (Dictyopharinae: Orthopagini) is described based on a nymph from Rovno amber; it also occurs in Baltic amber. A small additional wax plate dorsal to the large wax plate of abdominal tergites VI-VIII is first reported in this and other genera of Dictyopharidae. A lectotype is designated for Pseudophana reticulata Germar & Berendt, 1856 transferred to Protepiptera (Achilidae): Protepiptera reticulata (Germar & Berendt, 1856), comb. n.

New Staphylinidae (Coleoptera) records with new collection data from New Brunswick, and an addition to the fauna of Quebec, Canada: Aleocharinae

Thirty-eight species of Aleocharinae are newly reported from New Brunswick, bringing the total number of species known from the province to 216. Thirty-one of these species are newly recorded for the Maritime provinces, and four of them, Phloeopora oregona Casey, Gyrophaena michigana Seevers, Gyrophaena wisconsinica Seevers, and Tomoglossa decora (Casey), are newly recorded for Canada. Tomoglossa constitutes a new generic record for Canada. Collection and habitat data for all these species are presented and discussed. Color habitus, median lobe of the aedeagus, and male tergite and sternite 8 images are presented for the first time for Phloeopora oregona, and references to illustrations are provided for all other species included in this paper. A color habitus image is presented for Tomoglossa decora.

Discovery of three new species of the genus Gyrophaena Mannerheim (Coleoptera: Staphylinidae: Aleocharinae) in Korea

Three new species of the mycophagous aleocharine genus Gyrophaena Mannerheim are described in Korea. The types and paratypes of the new species are designated. Illustrations of the diagnostic characters and habitus photographs of new species are provided with a key to Korean species of Gyrophaena.     

Descriptions of three new species of the Termitophilous tribe Termitopaediini in China (Coleoptera,Staphylinidae, Aleocharinae)

Three new species belonging to two genera of the aleocharine tribe Termitopaediini Seevers, viz., Dioxeuta rara Song & Li, sp. n., D. yunnanensis Song & Li, sp. n., and Termitopulex sinensis Song & Li, sp. n. from Baihualing Natural Reserve (Southwest China: Yunnan) are described and illustrated. This is the first record of Termitopulex Fauvel, 1899 from China.     

Revision of the rove beetle genus Antimerus (Coleoptera, Staphylinidae, Staphylininae), a puzzling endemic Australian lineage of the tribe Staphylinini

The genus Antimerus Fauvel, 1878, endemic to eastern Australia and Tasmania and a phylogenetically enigmatic member of the large rove beetle tribe Staphylinini, is revised. The genus and each of its four previously known species are redescribed, and a lectotype is designated for Antimerus punctipennis Lea, 1906. Five species are described as new: Antimerus metallicussp. n., Antimerus jamesrodmanisp. n., Antimerus gracilissp. n., Antimerus bellussp. n. and Antimerus monteithisp. n., so that the number of known species in this genus now totals nine. For the first time Antimerus larvae are described, tentatively identified as Antimerus smaragdinus Fauvel, 1878, Antimerus punctipennis and Antimerus metallicus. Available distributional and bionomic data are provided for each species and summarized in the discussion. Adult and larval morphology of Antimerus and its distribution patterns are discussed in the broader context of new data on the evolution of the entire tribe Staphylinini, and with respect to the formation of the Australian fauna of this tribe. The phylogenetic position of Antimerus within Staphylinini remains unresolved pending a targeted formal study. However, a majority of currently available data suggests that it could be a basal member of the recently recovered monophyletic clade of Staphylinini tentatively called "Staphylinini propria".
