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.     

New species of the subfamily Conoderinae (Coleoptera: Curculionidae) in Dominican amber

Eulechriops argyrosoman. sp. (Curculionidae: Conoderinae: Lechropini) and Geratozygops platysoman. sp., Geratozygops stenosoman. sp. and Geratozygops arsinotusn. sp. (Curculionidae: Conoderinae: Zygopini) are described from Dominican amber. The small size, nearly parallel sides of the pronotum and silvery sheen distinguish Eulechriops argyrosoma from extant members of the genus, which have not been recorded from Hispaniola. Size and rostral and pronotal characters separate the three Geratozygops species from the single species (Geratozygops atropos) previously described from Dominican amber.http://www.zoobank.org/urn:lsid:zoobank.org:pub:89BC7F43-6C1A-4A6A-839B-CE94C7F6F140     

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.     

On the genus Eumyllocerus Sharp （Coleoptera： Curculionidae： Entiminae） with description of two new species from China

Two new species of the genus Eumyllocerus Sharp, 1896, of the subfamily Entiminae Schoenherr, 1823, are described from China. Eumyllocerus longisetus sp. n. may be distinguished from other species of the genus by its long bristle-like, erect setae on the intervals, each of which is longer than the width of the second interval, the setae arrangedin double rows, and its shell-like, shiny, dense, metallic green scales. Eumyllocerus rotundicorpus sp. n. may be distinguished from any other Eumyllocerus species by its oval and inflated elytral shape, short stout metepisternum, small humeri, elytral setae shorter than 0.5 times the width of the second interval, the setae arranged in double rows, and its golden copper and pearl gray scales. The taxonomy of the genus is discussed. The two new species are described and habitus photographs and figures of diagnostic characters are provided. The type specimens of the new species are deposited in the Institute of Zoology, Chinese Academy of Sciences, Beijing, China (holotype and paratypes) and the Korean Entomological Institute, Korea University, Seoul, Korea (paratypes).     

New species of the subfamily Cossoninae (Coleoptera: Curculionidae) in Dominican amber

The following new genus and seven new species of Cossonine weevils (Curculionidae: Cossoninae) are described from Dominican amber: Acamptus exilipes Poinar and Legalov, n. sp. (similar to A. rigidus), Caulophilus camptus Poinar and Legalov, n. sp. (similar to C. bennetti), Caulophilus elongatus Poinar and Legalov, n. sp. (similar to C. swensoni), Caulophilus ruidipunctus Poinar and Legalov, n. sp., Dryotribus pedanus Poinar and Legalov, n. sp. (similar to D. amplioculus), Ogygius obrieni Poinar and Legalov, n. gen., n. sp. (similar to the genus Apotrepus), and Stenotrupis pumilis Poinar and Legalov, n. sp. (similar to S. breviscapus). A key to the Dominican amber species of the genus Caulophilus is provided. Based on the extant weevil fauna, it appears that the Hispaniolan Cossonine were more diverse in the Tertiary than at present. http://zoobank.org/urn:lsid:zoobank.org:pub:14D1CFC0-4967-4D22-888B-0DE3E157D6BD     

New species of the genus Glaesotropis (Insecta: Coleoptera: Anthribidae) from Rovno amber

A new species of the fungus weevil genus Glaesotropis is described from the Late Eocene Rovno amber. G. diadiasashai sp. nov. differs from G. weitschati and G. minor described from Baltic amber in having a longer rostrum and in the structure of its antennae, with the third and fourth antennomeres being longer than the first and second ones. Additionally, the new species differs from G. weitschati in being smaller, in having unswollen frons, and weakly and smoothly concave elytral margin near hind coxae. The new species also differs from G. minor in having an uninterrupted posterior transverse carina on the pronotum, elytra less convex longitudinally, and a slightly broadened rostrum at the attachment of antennae.     

New species of Late Eocene dermestid beetles (Coleoptera, Dermestidae) from the Rovno and Baltic ambers

Fossil beetles of the family Dermestidae are reviewed. Three new species are described: Dermestes progenitor and Megatoma electra from the Baltic amber and Dermestes vetustus from the Rovno amber (Late Eocene).     

A new genus and species of the rove beetle tribe Mesoporini from Baltic amber (Coleoptera: Staphylinidae: Aleocharinae)

A new extinct rove beetle, Palaeomesoporus electiricus gen. et sp.n., is described from a single specimen of Eocene Baltic amber. This fossil beetle is placed in the tribe Mesoporini, a ‘basal’ group of the mega-diverse subfamily Aleocharinae. Palaeomesoporus is easily discriminated from other mesoporine genera due to its less-developed antennal club, longer and slender elytron lacking a sinuate posterior margin, and prominently shorter mesotarsus. This finding sheds light on the paleodiversity and evolutionary history of the tribe and ‘basal’ Aleocharinae.     

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.     

A new species of Polydrusus (Polydrusus) Germar (Coleoptera:Curculionidae) from the Kurdistan region of Iraq

Polydrusus (s. str.) akreanus sp. n. is a new record of Curculionidae found in Iraqi Kurdistan. The new species is described, illustrated and compared with Polydrusus (s. str.) kadleci Borovec & Germann, 2013 known from Turkey and Iran, which is morphologically similar to the new species.

Species of two paleoendemic sap beetle genera of the Tribe Nitidulini (Nitidulidae: Coleoptera) from the Baltic and Dominican amber

Omositoidea gigantea Schaufuss, 1892 is redescribed; O. pubescens sp. nov. from the Baltic amber, Palaeometopia dominicana gen. et sp. nov. and P. colorata gen. et sp. nov. from the Dominican amber are described. The taxonomic position of the two genera and their probable bionomy are discussed.     

Descriptions of a broad-nosed weevil (Eudiagogini: Curculionidae) and false ladybird beetle (Nilionini: Nilionidae) in Dominican amber

A broad-nosed weevil, Promecops tumidirostris n. sp. (Eudiagogini: Curculionidae), and a false ladybird beetle, Nilio dominicana n. sp. (Nilionini: Nilionidae), are described from Dominican amber. P. tumidirostris can be distinguished from extant species by the greatly swollen apical portion of its rostrum, large eyes almost meeting on top of its head and a V-shaped suture separating the first and second abdominal sternites. N. dominicana differs from extant species by its small size and 18 elytral striae with small interstrial punctures. Neither tribe is represented in Hispaniola today, supporting earlier studies showing a greater biodiversity in the region during the mid-Tertiary than at present.     

A revision of the genus Paronthobium from New Caledonia (Coleoptera: Scarabaeidae: Scarabaeinae: Epilissini)

A revision of the New Caledonian genus Paronthobium Paulian 1984 is presented. Anonthobium Paulian 1984 is synonymized with Paronthobium Paulian 1984 after evaluating the diagnostic characters originally introduced by Paulian to separate them. Upon examination of the type specimens, Onthobium caledonicum Paulian 1935 is separated from O. simplex Fauvel 1903 and restored as valid. Anonthobium moui Paulian 1984 is synonymized with Anonthobium micros Paulian 1984. Fifteen new species are described: P. adio n. sp., P. daghfousi n. sp., P. dierkensi n. sp., P. farino n. sp., P. iac n. sp., P. julieni n. sp., P. memaoya n. sp., P. minutum n. sp., P. nasutum n. sp., P. orientale n. sp., P. peckorum n. sp., P. petchecara n. sp., P. subdentatum n. sp., P. taom n. sp. and P. tchingou n. sp. The genus Paronthobium is now composed of 22 species. Illustrations of parameres and of male protibiae are provided for each species. Distribution maps and a key to species are given.     

A new genus of Entiminae from North Africa,supported by a phylogenetic analysis (Coleoptera: Curculionidae: Entiminae)

The genus Holcophloeus gen. nov. is here proposed to include Trachyphloeus cruciatus Seidlitz, 1868, and two new species native to North Africa, based on a phylogenetic analysis and an evaluation of the diagnostic characters. The taxonomic position of Holcophloeus in relation to the tribes Trachyphloeini Lacordaire, 1863, and Holcorhinini Desbrochers, 1898, is discussed, and the new genus is attributed to the Holcorhinini. Holcophloeus laurae sp. nov. from south‐eastern Morocco and Holcophloeus weilli sp. nov. from northern Libya are described and illustrated and a key to the species of the new genus is given. The lectotype of Trachyphloeus cruciatus Seidlitz, 1868, is designated. The genus Massimiellus Borovec, 2009, is transferred from Trachyphloeini to Holcorhinini. © 2013 The Linnean Society of London     

Fossil carabids from Baltic amber -II - A new subgenus of Bembidion Latreille 1802 (Coleoptera: Carabidae: Bembidiini)

Bembidion (Archaeophilochthus) christelae a new subgenus and species belonging to the tribe Bembidiini (Coleoptera: Carabidae: Trechinae) preserved in a piece of Baltic amber (Eocene) is described. A comparison with recent fauna is made, and paleobiology of the species is hypothetized.     

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.     

Parabrosmolus novaeguineae,a new genus and species of the subfamily Brosmophycinae from Papua New Guinea (Bythitidae,Ophidiiformes)

Parabrosmolus novaeguineae, a new genus and species of the subfamily Brosmophycinae (family Bythitidae) is described, based on a single specimen from Papua New Guinea. The genus is unique in the tribe Brosmophycini in having six branchiostegal rays and ten precaudal vertebrae, and is also similarly distinguished from two brosmophycine genera,Melodichthys andBeaglichthys, tribal allocations of the two latter being uncertain.Parabrosmolus also differs from all other genera in the subfamily by the following combination of characters: head scaly, anal fin origin slightly before midpoint of body, eye diameter shorter than snout length, three developed rakers on first gill arch and 16 (14+2) caudal fin rays.     

New genera and new species of leaf beetles (Coleoptera: Polyphaga: Chrysomelidae) from Lowermost Eocene French amber
