New Tridactyloidea in Miocene amber from the Dominican Republic (Orthoptera: Caelifera)

Two new Tridactyloidea of the families Ripipterygidae and Tridactylidae are described from the Early Miocene (Burdigalian) amber of the Dominican Republic, namely: Archaeoellipes engeli n. gen., n. sp. (Tridactylidae: Tridactylinae) and Mirhipipteryx antillarum n. sp. (Ripipterygidae). These new taxa represent the fi rst record of Tridactyloidea in Dominican amber and the fi rst fossil record of Ripipterygidae, which are otherwise known only from the extant fauna.     

Two new non-biting midges from the Early Cretaceous Lebanese amber (Diptera: Chironomidae)

Abstract

Two chironomid flies, Ziadeus kamili n. gen., n. sp. and Paicheleria magnifica n. gen., n. sp., respectively attributed to the recent subfamilies Tanypodinae and Prodiamesinae, are described from the Early Cretaceous Lebanese amber. Although very old, this non-biting midge fauna was very diverse with no less than 11 genera and species. However, it was also strongly different from the recent faunas for the complete absence of the Chironominae, that is today the dominant subfamily. The development of the modern chironomid fauna occurred during the Late Cretaceous and/or the Early Paleogene, but when and how?     

Austrini - a new tribe of Tropiduchidae planthoppers from the Eocene Baltic amber (Hemiptera: Fulgoromorpha)

A new tribe Austrini n. trib. of Tropiduchidae planthoppers from the Eocene Baltic amber is described to comprise Austris raffelis n. gen., n. sp. Fossils ascribed to family Tropiduchidae are discussed.     

New psychopsoid Neuroptera from the Early Cretaceous of Baissa,Transbaikalia

Two new genera and fi ve new species of the psychopsoid Neuroptera (one of which is unnamed) are described from the Early Cretaceous locality at Baissa, Transbaikalia, Russia: Epipsychopsis fusca n. gen., n. sp., E. variegata n. sp. (Psychopsidae), Pseudopsychopsis gradata n. gen., n. sp., P. baissensis n. sp. (Brongniartiellidae), and Sophogramma sp. (Kalligrammatidae).     

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

Three new monotypical genera of leaf beetles are described: Aoriopsis eocenicus n. gen, n. sp. and Acolaspoides longipes n. gen., n. sp. from the subfamily Eumolpinae, and also Crepidocnema yantarica n. gen., n. sp. from the subfamily Alticinae. Short reviews of known fossil records of the mentioned subfamilies are given and position of the new genera discussed.     

New Middle Permian insects from Salagou Formation of the Lodève Basin in southern France (Insecta: Pterygota)

Summary

New insects are described from the Middle Permian (Guadalupian) of Salagou Formation in the Lodève Basin (Languedoc region, France). Palaeopterans are represented by new odonatopterans viz. Huangiopterum lodevense n. gen., n. sp. and Huangiopterum species B, attributed to clade Panodonata (Huangiopteridae n. fam.), already recorded through the family Saxonagrionidae in the same formation, and a diaphanopterodean Martynovia cf. halli Beckemeyer 2004 (Martynoviidae) known from the Lower Permian of Oklahoma. Archaeorthopterans are supplemented by Bethouxia ariegensis n. gen., n. sp., Paralongzhua elongata n. gen., n. sp., Lodevolongzhua incompleta n. gen., n. sp., the caloneurodean Jarmiloptera mouralensis n. gen., n. sp., and a cnemidolestodean cf. Tococladus sp. (Tococladidae). Permophyllum rotundatum n. sp. (?Tettigoniidae) demonstrates the first presence of Orthoptera with wings probably mimicking Peltaspermales reproductive organs in Late Palaeozoic possibly analogous to the known crypsis of roachoid tegmina with pteridosperm pinnules. Frequent occurrence of hardly identifiable grylloblattid wing fragments support their significant role in term of abundance and diversity of the Permian faunas. New taxa based on wing venation pattern as Genera and species undetermined A, B (Liomopteridae), Permobaharellus salagousensis n. gen., n. sp. (family uncertain), Lodevophlebia reticulata n. gen., n. sp. (Sylvaphlebiidae), Oborella lodevensis n. sp. (Euryptilonidae), and Genus and species undetermined C, were described. Paoliida is represented by a paoliid gen. et sp. indet. and three anthracoptilids Strephocladus gandi n. sp., Strephocladus mouralensis n. sp., Lodevocladus subtilis n. gen., n. sp. The first record of miomopteran Palaeomantis sp. (Paleomanteidae) from Salagou Formation is presented. Acercarian insects are represented by the first record of Thripida and diverse new hemipterans, namely Euroscytina lutevanorum n. gen., n. sp. (Cicadomorpha: Scytinopteridae), Prosbole dio n. sp., Prosbole garrici n. sp., Pervestigia cf. veteris Becker-Migdisova 1961 (Prosbolidae), Archescytina species A (Paleorrhyncha: Archescytinidae) and Permopsyllidium lesclansis n. sp. (Sternorrhyncha: Psylloidea: Protopsyllidiidae). Entomofauna from the Salagou Formation demonstrate highly diverse insect communities with some taxa linked to early and late Permian ones known from assemblages in Euramerica and Russia, such as Obora (Czech Republic), Wellington Formation (Kansas and Oklahoma, USA), and Tshekarda (Ural, Russia).     

The oldest occurrence of immature Diptera (Insecta), Middle Triassic,France

The oldest fossil Diptera are known from the Grès à Voltzia Formation (Upper Buntsandstein) of the northern Vosges Mountains (northeastern France), the age of which is early Anisian (early Middle Triassic). Six monotypic genera assigned to all the major lineages of Diptera (except for the Culicomorpha) were described from these beds based on adults (Krzeminski et al. 1994; Krzeminski & Krzeminska 2003). Immature Diptera also occur in the Grès à Voltzia (ca 30 specimens). Pupae are abundant whereas the larvae are extremely rare. The most numerous and well-preserved pupal type has been assigned to Voltziapupa n. gen. (V. tentata n. sp. and V. cornuta n. sp.). These pupae display plesiomorphic characters combined with possibly derived ones. Among the larvae, Anisinodus crinitus n. gen., n. sp. shows culicomorph features. It represents the earliest Culicomorpha (Chironomoidea inc. fam.) known up to date. The other types of dipteran immatures (six pupal and two larval ones) occurring in the Grès à Voltzia are less well preserved, so that their systematic position is difficult to determine and they have been assigned to the Nematocera incertae sedis. These immature Diptera are the first ones recorded from the Triassic.     

Revision of the genus Thermistis Pascoe 1867, with descriptions of three new species (Coleoptera: Cerambycidae: Lamiinae: Saperdini)

The genus Thermistis Pascoe 1867 is revised. T. croceocincta conjunctesignata Rondon & Breuning 1971 is upgraded to a species and newly recorded from China and Myanmar. T. xanthomelas Holzschuh 2007 is newly recorded from Vietnam, Laos and Myanmar. T. sulphureonotata Pu 1984 is newly recorded from Vietnam and Laos. Three new species are described from China: T. hainanensis Lin & Yang n. sp. from Hainan Island, T. kaiyuni Chou & Kurihara n. sp. from Taiwan Island and T. cheni Lin & Chou n. sp. from Yunnan and Sichuan provinces. Photographs of habitus and terminalia and a key to the eleven valid species of Thermistis are presented.     

Two new species of the genus Rhynchitobius Sharp, 1889 (Coleoptera: Rhynchitidae) in Dominican amber

New species of rhynchitid weevils, Rhynchitobius tanyrhinus n. sp. and R. xuthocolus n. sp. (Coleoptera: Rhynchitidae) in the tribe Auletini are described from Dominican amber. The former species is characterized by a long rostrum, narrow pronotum and elytra, rugose elytral intervals and distinct elytral striae. The latter species has a short rostrum, wide antennal club, yellow legs, non-rugose elytral intervals and weak elytral striae. The present study describes the first representatives of the family Rhynchitidae from Dominican amber.     

The earliest fossil schizopterid bug (Insecta: Heteroptera) in the Lower Cretaceous amber of Lebanon

The schizopterid bug Libanohypselosoma popovi n. gen., n. sp. belonging to the subfamily Hypselosomatinae is described from the Lower Cretaceous amber of Lebanon. This fossil is the earliest record of the Schizopteridae. The species is distinguished from its related taxa, a discussion is given.     

Descriptions of the first semi-aphenopsian troglobiotic Patrobini and of a new anophthalmic cave-dwelling Trechini from central Sichuan,China (Coleoptera: Caraboidea)

Summary

The first known troglobiotic species belonging to the ground beetle tribe Patrobini is reported from a limestone cave called Lianhua Dong in Pengzhou, a suburb county-level city in northern Chengdu, Sichuan Province, China. Troglopatrobus zhouchaoi n. gen., n. sp., is an eyeless and large-sized patrobine beetle with extremely elongated body (esp. head and elytra) and appendages. Duvalioblemus (Shublemus) liyuani n. subgen., n. sp., a minute anophthalmic trechine species, is also discovered from the same cave. It is the first cave-dwelling species belonging to this genus already known as endogean from Sichuan and Yunnan provinces.     

A new Early Cretaceous snakefly (Raphidioptera: Mesoraphidiidae) from El Soplao amber (Spain

A virtually complete specimen of the family Mesoraphidiidae (Insecta: Raphidioptera) is described as Cantabroraphidia marcanoi n. gen., n. sp. It was found in early Albian amber from a new deposit named El Soplao within the Las Peñosas Fm. in northwestern Cantabria (Spain). It has been compared to all adult fossils placed in the Mesozoic family Mesoraphidiidae. Some taxonomical comments are provided, and we propose to restore the genus Yanoraphidia Ren 1995 and the combination Yanoraphidia gaoi Ren 1995 stat. rest., provisionally retained in the family Mesoraphidiidae.     

Abraracourcix curvivenatus n. gen. n. sp. from the Lowermost Eocene Oise amber (Hemiptera: Fulgoromorpha: Ricaniidae)

An extinct genus Abraracourcix n. gen. with A. curvivenatus n. sp. is described based on the specimen from the Lowermost Eocene Oise amber. The venation characters and possible hostplant relationships, as well as taxonomic position and biogeographical pattern of recent Pochazoides generic group are discussed.     

Burmaphlebia reifi gen. et sp. nov., the first anisozygopteran damsel-dragonfly (Odonata: Epiophlebioptera: Burmaphlebiidae fam. nov.) from Early Cretaceous Burmese amber

A new family, genus and species of damselfly, Burmaphlebia reifi gen. et sp. nov. (Burmaphlebiidae fam. nov.), is described as the second fossil odonate from Early Cretaceous Burmese amber. Its phylogenetic position is discussed and the fossil is attributed to a new family at the base of the anisozygopteran grade, probably closely related to the Recent relict group Epiophlebiidae. It is the first record of the ‘anisozygopteran’ grade from amber and the smallest known representative of this group.http://zoobank.org/6EFE7288-BD89-42F9-BFA5-804CE6B904A6     

New genera and species of Jumping Ground Bugs (Hemiptera: Schizopteridae) in Dominican and Burmese amber,with a description of a meloid (Coleoptera: Meloidae) triungulin on a Burmese specimen

New genera and species of jumping ground bugs (Hemiptera: Schizopteridae) are described in Dominican and Burmese amber. In Dominican amber are described: Hypselosoma dominicana Poinar & Brown sp. n., Schizoptera dominicana Poinar sp. n. and Schizoptera hispaniolae Poinar sp. n. In Burmese amber are described: Lumatibialis burmitis Poinar gen. et sp. n. and Hexaphlebia burmanica Poinar gen. et sp. n. A triungulin attached to the dorsum of the abdomen of Lumatibialis burmitis is described as Microentomus epibatus Poinar gen. et sp. n. in the family Meloidae (Coleoptera). This specimen represents the oldest known triungulin and the first fossil phoretic association of a triungulin and hemipteran.     

First Baltic amber megapodagrionid damselfly (Odonata: Zygoptera)

Electropodagrion szwedoi n. gen., n. sp., first Baltic amber megapodagrionid damselfly, is described. The European and North American fossils document a very high diversity and a much wider distribution of this group of damselflies during the Cenozoic than today. A checklist of described fossil species of damselflies of the family Megapodagrionidae is given.     

The earliest fossil record of the extant rove beetle genus Phloeocharis from mid-Cretaceous Kachin amber of northern Myanmar and its biogeographic implications (Coleoptera: Staphylinidae: Phloeocharinae)

Phloeocharis Mannerheim is the largest genus within the problematic rove beetle subfamily Phloeocharinae, with a single extinct and 44 recent species recorded from the Holarctic Region. Until now, the oldest fossil record of Phloeocharis was known from Late Cretaceous (Turonian) amber from New Jersey, USA. Here we describe 2Phloeocharis burmana n. sp. from mid-Cretaceous (Albian–Cenomanian) Kachin amber from northern Myanmar, as the earliest extinct species of this genus. Our finding also sheds light on the biogeography of Phloeocharis, since no recent or extinct species have so far been recorded from the Oriental Region. Furthermore, the discovery of 2P. burmana n. sp. extends the Mesozoic diversity of the phloeocharine rove beetles both taxonomically and morphologically, particularly from Kachin amber.     

Brachyceran Diptera (Insecta) in Cretaceous ambers, Part IV, Significant New Orthorrhaphous Taxa

Thirteen species of basal Brachycera (11 described as new) are reported, belonging to nine families and three infraorders. They are preserved in amber from the Early Cretaceous (Neocomian) of Lebanon, Albian of northern Spain, upper Albian to lower Cenomanian of northern Myanmar, and Late Cretaceous of New Jersey USA (Turonian) and Alberta, Canada (Campanian). Taxa are as follows, with significance as noted: In Stratiomyomorpha: Stratiomyidae (Cretaceogaster pygmaeus Teskey [2 new specimens in Canadian amber], Lysistrata emerita Grimaldi & Arillo, gen. et sp. n. [stem-group species of the family in Spanish amber]), and Xylomyidae (Cretoxyla azari Grimaldi & Cumming, gen. et sp. n. [in Lebanese amber], and an undescribed species from Spain). In Tabanomorpha: Tabanidae (Cratotabanus newjerseyensis Grimaldi, sp. n., in New Jersey amber). In Muscomorpha: Acroceridae (Schlingeromyia minuta Grimaldi & Hauser, gen. et sp. n. and Burmacyrtus rusmithi Grimaldi & Hauser gen. etsp. n., in Burmese amber, the only definitive species of the family from the Cretaceous); Mythicomyiidae (Microburmyia analvena Grimaldi & Cumming gen. et sp. n. and Microburmyia veanalvena Grimaldi & Cumming, sp. n., stem-group species of the family, both in Burmese amber); Apsilocephalidae or near (therevoid family-group) (Kumaromyia burmitica Grimaldi & Hauser, gen. et sp. n. [in Burmese amber]); Apystomyiidae (Hilarimorphites burmanica Grimaldi & Cumming, sp. n. [in Burmese amber], whose closest relatives are from the Late Jurassic of Kazachstan, the Late Cretaceous of New Jersey, and Recent of California). Lastly, two species belonging to families incertae sedis, both in Burmese amber: Tethepomyiidae (Tethepomyia zigrasi Grimaldi & Arillo sp. n., the aculeate oviscapt of which indicates this family was probably parasitoidal and related to Eremochaetidae); and unplaced to family is Myanmyia asteiformia Grimaldi, gen. et sp. n., a minute fly with highly reduced venation. These new taxa significantly expand the Mesozoic fossil record of rare and phylogenetically significant taxa of lower Brachycera.     

The first Ironomyiidae from mid‐Cretaceous Burmese amber provides insights into the phylogeny of Phoroidea (Diptera: Cyclorrhapha)

Macalpinomyia jiewenae gen. et sp.n. is described from the mid‐Cretaceous (～99 Ma) amber of Myanmar. Macalpinomyia jiewenae is the first Oriental representative of the enigmatic family Ironomyiidae (Diptera: Phoroidea), currently known from a single extant genus restricted to southeastern Australia, plus a monotypic genus from Canadian amber and three controversial genera based on impression fossils from China, Mongolia and Russia. A phylogenetic analysis of all Phoroidea families, including all ironomyiid extant and extinct genera, corroborates the monophyly of Ironomyiidae, and Macalpinomyia gen.n. is assigned to the subfamily Sinolestinae. Cretonomyiinae subfam.n. , is erected to accommodate the basal lineage of Ironomyiidae. Lebambromyia acrai Grimaldi & Cumming, previously placed in Ironomyiidae, is supported as an early branching lineage of Platypezidae. Our topology proposes that Ironomyiidae is sister to the remaining Phoroidea. The phylogenetic results, in combination with the fossil ages and relevant molecular divergence time analysis, suggests that Ironomyiidae probably originated at least in the Berriasian of the Early Cretaceous (～140 Ma).
