New genera and species of Scelionidae (Insecta: Proctotrupoidea) from Rovno amber

Two new genera and three new species of parasitic wasps from the family Scelionidae are described from the Late Eocene Rovno amber: Pseudotelea gracilis Kononova, gen. et sp. nov. (subfamily Scelioninae), Pseudidris striatus Kononova, gen. et sp. nov., and Ceratobaeoides cornutus Kononova, sp. nov. (subfamily Baeinae). The new taxa are compared with representatives of the Recent fauna.     

A new subfamily of ichneumon wasps (Insecta: Hymenoptera: Ichneumonidae) from the Upper Cretaceous of the Russian Far East

A new subfamily of ichneumon wasps, Labenopimplinae subfam. nov. (Ichneumonidae), is described from the Cenomanian Ola Formation of the locality Obeshchayushchiy, Magadan Region, Russian Far East. The subfamily is highly diverse morphologically and combines characters of the Labeninae and Pimplinae. It includes 11 new species described in five new genera: Labenopimpla rasnitsyni gen. et sp. nov., L. kasparyani sp. nov., Armanopimpla zherikhini gen. et sp. nov, Ramulimonstrum intermedium gen. et sp. nov., Rugopimpla vulgaris gen. et sp. nov., R. fallax sp. nov., R. angusticella sp. nov., R. macra sp. nov., R. matrona sp. nov., Micropimpla lucida gen. et sp. nov., and M. obscura sp. nov. Also described is a new monotypic genus, Tryphopimpla xoridoptera gen. et sp. nov., which combines characters of the Tryphoninae, Pimplinae, and Xoridinae and cannot be currently placed into any of the known subfamilies. The population of fossil ichneumon wasps at this locality is distinctly dominated by females.     

New radiolarian genera and species from the Lower Permian of the Southern Urals and Northern Mugodzhary

Two new genera and five new species of Lower Permian radiolarians, Arcoclathrata alekseevi gen. et sp. nov., Entactinia pinrasensis sp. nov., Microporosa rozhnovi gen. et sp. nov., M. aktastensis sp. nov., and Somphoentactinia saecularis sp. nov., from the Southern Urals and Northern Mugodzhary are described. The new spherical radiolarian taxa belong to three orders: Entactiniata, Cancelliata, and Spongiata of two classes, Sphaerellaria and Spumellaria.     

LATE JURASSIC PALAEONTINIDS (HOMOPTERA: AUCHENOR-RHYNCHA) FROM HEBEI AND LIAONING PROVINCES IN CHINA*

Abstract Two new genera and six new species of Palaeontinidae are named and described: Liaocossus hui gen. et sp. nov., L. beipiaoensis gen. et sp. nov., L. exiguus gen. et sp. nov., L. fengningensis gen. et sp. nov., L. pingquanensis gen. et sp. nov., and Miracossus ingentius gen. et sp. nov., The entire body of these new fossils are perfectly preserved and enable us to fix accurately the body characteristics of primitive palaeontinids. All the specimens were collected from Late Jurassic Yixian Formation of Northern Hebei and Western Liaoning Provinces in China.     

New fossil mantidflies (Insecta: Neuroptera: Mantispidae) from the Mesozoic of north‐eastern China

Abstract:  Three new genera and four new species of the extinct mantidfly subfamily Mesomantispinae (Insecta: Neuroptera: Mantispidae) are described from the Lower Cretaceous Yixian Formation of Liaoning and the Middle Jurassic Jiulongshan Formation of Inner Mongolia: Archaeodrepanicus nuddsi gen. et sp. nov., A. acutus gen. et sp. nov., Sinomesomantispa microdentata gen. et sp. nov., (Yixian Formation) and Clavifemora rotundata gen. et sp. nov. (Jiulongshan Formation). The specimens described herein represent the first Mesozoic mantidfly compression fossils to have body parts preserved, including the specialized raptorial forelegs articulated to the prothorax anteriorly, an autapomorphy of the family. These new taxa further confirm the placement of the subfamily Mesomantispinae within the family Mantispidae; however, the monophyly of Mesomantispinae has not been confirmed, and it is likely that it will prove to be paraphyletic.     

New species of sap beetles (Coleoptera: Nitidulidae: Nitidulini) from the Baltic and Bitterfeld ambers

A new genus, Microsoronia, gen. nov., and new species of this genus, M. hoffeinsorum, sp. nov. from the Bitterfeld amber and M. kerneggeri sp. nov., M. nigerrima sp. nov., and M. interfax, sp. nov. from the Baltic amber, are described. The earliest known member of the genus Phenolia, P. (Lasiodites) angustitibialis, sp. nov., is described from the Baltic amber. The systematic position of these two genera, their possible evolution, as well as the possible ecology and bionomics of their members are discussed. It is shown that “Phenolia” incapax Scudder, 1890 should be included in the family Peltidae, rather than Nitidulidae.     

New click beetles (Coleoptera: Elateridae) from the cretaceous of Russia and Kazakhstan

A new tribe, two new genera, and seven new species of click beetles are described: Pollostelaterini, trib. nov., Pollostelater baissensis, gen. et sp. nov. from the Lower Cretaceous of Transbaikalia (Baisa locality), five new species in the genus Cryptocoelus Dolin et Nel C. sinitshenkovae, sp. nov. (Romanovka locality), C. shcherbakovi, sp. nov., C. baissensis, sp. nov., C. lukashevichae, sp. nov., C. dolini, sp. nov. (all from Baisa locality), and Turonelater giganteus, gen. et sp. nov. from the Turonian of Southern Kazakhstan (Kzyl-Dzhar locality).

Two new genera, Caveana, gen. nov. and Triviola, gen. nov., belonging to the subfamily Torodorinae (Lecithoceridae) are described, based on Caveana diemseoki, sp. nov. and Triviola puiensis, sp. nov. At the same time, two new Torodora species, T. karismata, sp. nov. and T. youwon, sp. nov., are also described from Thailand. Images of adults and genitalia are given.     

New bugs of the family Archegocimicidae (Hemiptera: Heteroptera) from the Upper Jurassic of Mongolia

Two new genera and five new species of Archegocimicidae are described from the Upper Jurassic of the Shar-Teg locality in Mongolia: Shartegocimex rasnitsyni, gen. et sp. nov., S. distans, sp. nov., Shartegocorpus paranotalis, gen. et sp. nov., Saldonia formosa, sp. nov., S. insolita, sp. nov.     

Kimmeridgian-Volgian Aporrhaidae (Stromboidea: Gastropoda) of the Russian Platform

Kimmeridgian-Volgian Aporrhaidae from European Russia are described for the first time. They are referred to three genera, including two new genera, Undoriptera gen. nov. and Volgacheilus gen. nov. with three new species, Undoriptera tridactylus sp. nov., Volgacheilus rogovi sp. nov., and Dicroloma tenuistriata sp. nov.     

Snipe flies (Diptera: Rhagionidae) from the Daohugou Formation (Jurassic), Inner Mongolia,and the systematic position of related records in China

Abstract: Four new species referred to three new genera and one known genus of fossil snipe flies (Family Rhagionidae) from the Daohugou Formation of Chifeng City in Inner Mongolia, north‐eastern China, are described as Daohugorhagio elongatus gen. et sp. nov., Parachrysopilus jurassicus gen. et sp. nov., Sinorhagio sinuatus sp. nov. and Trichorhagio gregarius gen. et sp. nov. These taxa represent only a fraction of the rhagionid assemblage in the Daohugou biota. They contribute towards the high diversity and abundance of snipe flies during the latest Middle Jurassic – earliest Late Jurassic. The diagnosis of Sinorhagio K. Zhang, Yang and Ren, 2006 is revised based on the new results. Many genera and species from the Lower Cretaceous of China have been assigned to Rhagionidae. Most of these do not actually belong to this family: specifically Mesorhagiophryne incerta Hong and Wang, 1990, M. robusta Hong and Wang, 1990, Mesostratiomyia laiyangensis Hong and Wang, 1990, Stratiomyopsis robusta Hong and Wang, 1990, Longhuaia orientalis Hong, Wang and Sun, 1992, Basilorhagio venusius Ren, 1995. Pauromyia oresbia Ren, 1998 is transferred to an archisargid genus as Sharasargus oresbius (Ren, 1998) comb. nov.     

A NEW LOOK AT AN ANCIENT ORDER: GENERIC REVISION OF THE BANGIALES (RHODOPHYTA)1

The red algal order Bangiales has been revised as a result of detailed regional studies and the development of expert local knowledge of Bangiales floras, followed by collaborative global analyses based on wide taxon sampling and molecular analyses. Combined analyses of the nuclear SSU rRNA gene and the plastid RUBISCO LSU (rbcL) gene for 157 Bangiales taxa have been conducted. Fifteen genera of Bangiales, seven filamentous and eight foliose, are recognized. This classification includes five newly described and two resurrected genera. This revision constitutes a major change in understanding relationships and evolution in this order. The genus Porphyra is now restricted to five described species and a number of undescribed species. Other foliose taxa previously placed in Porphyra are now recognized to belong to the genera Boreophyllum gen. nov., Clymene gen. nov., Fuscifolium gen. nov., Lysithea gen. nov., Miuraea gen. nov., Pyropia, and Wildemania. Four of the seven filamentous genera recognized in our analyses already have generic names (Bangia, Dione, Minerva, and Pseudobangia), and are all currently monotypic. The unnamed filamentous genera are clearly composed of multiple species, and few of these species have names. Further research is required: the genus to which the marine taxon Bangia fuscopurpurea belongs is not known, and there are also a large number of species previously described as Porphyra for which nuclear SSU ribosomal RNA (nrSSU) or rbcL sequence data should be obtained so that they can be assigned to the appropriate genus.     

Megapanorpa,a new genus with a single anal horn in males from Oriental China (Mecoptera: Panorpidae)

A new genus of Panorpidae, Megapanorpa gen. nov. , is erected for five new species, Megapanorpa grandis sp. nov. (type species), M. absens sp. nov. , M. gaokaii sp. nov. , M. jiangorum sp. nov. and M. wanghongjiani sp. nov. This genus is similar to Cerapanorpa Gao et al., 2016 in a single anal horn on the sixth tergum of male, but can be differentiated from the latter by the following characters: the seventh abdominal segment of male is constricted and stalk‐like at base, the subgenital plate of female with a pair of lateral plates, and the medigynium of female with a concealed axis. Keys to genera of Panorpidae and species of Megapanorpa gen. nov. are presented. The morphology and function of anal horns in different genera and species have been discussed.     

Mesozoic Trachypachidae (Insecta: Coleoptera) from China

Abstract: Four well‐preserved beetles, attributed to Eodromeinae within Trachypachidae, are described from the Mesozoic of Inner Mongolia, China. Eodromeus robustus sp. nov., E. daohugouensis sp. nov. and Unda chifengensis sp. nov. are from the Middle Jurassic of Daohugou. The diagnostic characters for the two genera are revised, and all species of these genera are keyed. A new genus and species, Sinodromeus liutiaogouensis gen. nov., sp. nov., is described from the Lower Cretaceous Yixian Formation of Liutiaogou. The current fossil records of Trachypachidae from China are reviewed, and only five species (four described here) can be convincingly attributed to this family. The morphological disparity of Mesozoic Eodromeinae suggests that they evolved a broad spectrum of locomotory lifestyles.     

New mesozoic Ithyceridae beetles (Coleoptera)

A new subfamily, Mongolocarinae subfam. nov. of the family Ithyceridae, from the Middle-Upper Jurassic and Lower Cretaceous of Asia is described. It includes five genera with five species: Palaeocar gen. nov. (with P. princeps sp. nov.), Mongolocar gen. nov. (M. orcinus sp. nov.), Praecar gen. nov. (P. stolidus sp. nov.), Karacar gen. nov. (M. contractus sp. nov.), and Baissacar gen. nov. (B. passarius sp. nov.).     

New gall midges of the tribe Leptosynini (Diptera,Cecidomyiidae) from the Late Eocene ambers and the classification of the supertribe Heteropezidi

Three new genera and 27 new species of gall midges are described from the Late Eocene ambers: Henria baltica sp. nov., Frirenia manca sp. nov., F. musicata sp. nov., Leptosyna samlandica sp. nov., L. fastosa sp. nov. from Baltic amber and H. xystica sp. nov., H. liquida sp. nov., Stellasegna vlaskini gen. et sp. nov., S. vaporea sp. nov., S. nexa sp. nov., Rasnitsia verticosa gen. et sp. nov., F. rohdendorfi sp. nov., F. schevchenkoi sp. nov., F. melica sp. nov., F. lukashevichae sp. nov., F. leporidis sp. nov., F. marmarygma sp. nov., F. vesana sp. nov., Vincinescia alisae gen. et sp. nov., L. margarita sp. nov., L. munifera sp. nov., L. sukachevae sp. nov., L. assa sp. nov., L. larga sp. nov., L. vegeta sp. nov., L. vaticina sp. nov., and L. shcherbakovi sp. nov. from Rovno amber. Strobliella capitata Fedotova is redescribed as Henria capitata (Fedotova, 2004) (comb. nov.). Diagnoses of Henria (= Electroxylomyia Nel et Prokop, syn. nov.), Frirenia, and Leptosyna are revised. As a result, Henria comprises 3 extant and 5 extinct (Late Eocene) species, including H. eocenica (Nel et Prokop), comb. nov. (= Electroxylomyia eocenica), Frirenia comprises 1 extant and 10 Late Eocene species, and Leptosyna comprises 3 extant and 11 Late Eocene species. The tribe Heteropezini is elevated to the supertribal rank (Heteropezidi) and included in the subfamily Lasiopterinae. Leptosynini is treated as a separate tribe, and Lasiopterinae is considered as part of Cecidomyiidae s. str. (i.e., excluding Lestremiidae). Keys to the tribes and genera of Heteropezidi and to species of Henria, Stellasegna, Frirenia, and Leptosyna are provided. The gall midge faunas of the Rovno and Baltic ambers are compared. Phylogenetic relationships within the supertribe are hypothesized.     

Revision of the Antillocaprinidae Mac Gillavry (Hippuritida,Bivalvia) and their position within the Caprinoidea d’Orbigny

The rudist bivalve family Antillocaprinidae Mac Gillavry is revised following a study of nearly all available material in museum collections. Based on differences in their myocardinal arrangements, three subfamilies are recognized: the Titanosarcolitinae nov. subfam., the Antillocaprininae Mac Gillavry, and the Parasarcolitinae nov. subfam. Fifteen genera are described, of which ten are new: Eosarcolites nov. gen., Caenosarcolites nov. gen., Clinocaprina nov. gen., Rotacaprina nov. gen., Rudicaprina nov. gen., Stellacaprina nov. gen., Oligosarcolites nov. gen., Polysarcolites nov. gen., Alencasteria nov. gen., and Sawkinsonia nov. gen. Genera, which are placed in monophyletic radiations, are differentiated on minor differences in myocardinal arrangements, morphotype, and presence or absence of tubes. Six new species are described: Eosarcolites radiatus nov. gen., nov. sp., Caenosarcolites scholaris nov. gen., nov. sp., Rudicaprina planus nov. gen., nov. sp., Sawkinsonia maldonensis nov. gen., nov. sp., Alencasteria macrotubularis nov. gen., nov. sp., and Stellacaprina gunteri nov. gen., nov. sp. Cladistic analysis was performed on selected genera from the Caprinoidea, justifing the division of the Antillocaprinidae into three subfamilies, although extensive paraphyletic groupings exist in the lower part of the strict consensus tree. Weighting myocardinal characters produces a strict consensus tree largely consistent with current subfamily- and family-rank taxonomy, and is consistent with the order of appearance of taxa in the fossil record. The Antillocaprinidae show a major evolutionary radiation reaching a first peak in the middle Campanian, a decline in the late Campanian, and a second peak just before the rudist extinction at the end of the Cretaceous.     

PERMIAN OSTRACODS FROM THE LERCARA FORMATION (MIDDLE TRIASSIC–CARNIAN?), SICILY,ITALY

Abstract: A rich, diverse Permian ostracod fauna has been recovered from the red and grey, laminated shales and quartz‐rich shales of the Triassic Lercara Formation. Forty‐seven species have been identified, 13 of which are newly described here; they belong to 26 genera of which three are new: Anahuacia lercaraensis sp. nov., Aurigerites siciliaensis sp. nov., Bairdia portellaensis sp. nov., Cristanaria? katyae sp. nov., Fabalicypris gruendeli sp. nov., Lethiersa salomonensis gen. et sp. nov., Lethiersia sinusoventralis gen. et sp. nov., Portella trapezoida gen. et sp. nov., Siciliella elongata gen. et sp. nov., Siciliella infernespinosa gen. et sp. nov., Siciliella prima gen. et sp. nov., Siciliella quadrata gen. et sp. nov., and Siciliella spinorobusta gen. et sp. nov. The assemblages contain or are composed of palaeopsychrospheric forms, which are regarded as index fossils for deep environments. The bathymetry of the different associations in life is evaluated.
