New nematocerans (Insecta: Diptera) from the Late Jurassic of Mongolia

New nematoceran taxa are described based on isolated wings from the Late Jurassic Shar Teg locality (Mongolia): ?Nannotanyderus incertus sp. nov. (Tanyderidae), Crenoptychoptera liturata sp. nov. (Ptychopteridae), Chaoburmus amphilogos sp. nov., Mesocorethra cincta sp. nov. (Chaoboridae), Rasnicynomma additum gen. et sp. nov., and Palaeoperissomma ornatum sp. nov. (Perissommatidae).     

New archisargids from China (Insecta: Diptera)

The extinct family Archisargidae, which was rich in the Mesozoic, has been found in China, Kazakhstan and Mongolia. By now, six genera and 14 species have been found in Inner Mongolia and Liaoning Province of China. In this paper, two new species of the genus Mesosolva Hong, 1983 and a new genus Brevisolva gen. nov., represented by a new species belonging to the Archisargidae, are described from the Middle Jurassic deposits of Daohugou, Inner Mongolia. A key to the species of Mesosolva is given.     

Lacewings of the family Osmylidae (Insecta: Neuroptera) from the Upper Jurassic of Asia

Three new genera and five new species of osmylid lacewings are described from the locality Karatau (Kazakhstan, Upper Jurassic): Jurosmylus parvulus sp. nov. (Protosmylinae), Ensiosmylus acutus gen. et sp. nov. (Spilosmylinae), Kolbasinella elongata gen. et sp. nov. (Gumillinae), Arbusella bella gen. et sp. nov. and Jurakempynus arcanus sp. nov. (Kempyninae). Another new osmylid species (Jurakempynus sublimis sp. nov.) is described from the Upper Jurassic of Mongolia (Shar-Teg locality). The quantitative compositions of the osmylid faunas of Karatau and Shar-Teg are discussed.     

New Jurassic Cercopoidea from China and their evolutionary significance (Insecta: Hemiptera)

Abstract: A new family, Sinoalidae Wang and Szwedo fam. nov., is described from the Middle Jurassic Daohugou Biota (Inner Mongolia, China). Two new genera with three new species (Sinoala parallelivena Wang and Szwedo gen. et sp. nov., Jiania crebra Wang and Szwedo gen. et sp. nov., and Jiania gracila Wang and Szwedo sp. nov.) are erected based on well‐preserved whole‐bodied specimens. The morphological characters of Procercopidae and the new family are given, and a key to the species of Sinoalidae is presented. The genera Luanpingia Hong, 1983 and Huabeicercopis Hong, 1983 are revised and attributed to Sinoalidae. The genera Mesocercopis Hong, 1983 and Sinotettegarcta Hong, 1986 are considered junior synonyms of Anthoscytina Hong, 1983. Taxa assigned to Sinoalidae fam. nov. cannot be attributed to any previously known family, but share some general (plesiomorphic) characters with ancient Clypeata, for example, postclypeus distinctly swollen, transversely wrinkled, antenna with a flagellum of a few elongate segments, frons with median ocellus and lateral ocelli on crown. Moreover, the new family is closely related to Procercopidae (Cercopoidea) based on a pronotum with a median incision at the hind margin; tegmen slender, partly punctuate, basal portion of Sc not exceeding apex of basal cell, and hind legs with lateral spines. It has a mixture of ancestral characters shared with Hylicelloidea and Jurassic Procercopidae and some derived characters. Therefore, it is tentatively placed in Cercopoidea. A preliminary phylogram of Clypeata is presented based on the combination of fossil and morphological data.     

New hymenopteran insects (Insecta: Vespida) from the lower or middle Jurassic of India

Hymenopterans Xyelula alexandri Rasnitsyn, sp. nov. (Sepulcidae) and Kotaphialtites frankmortoni Rasnitsyn, gen. et sp. nov. (Ephialtitidae) are described from the Lower or Middle Jurassic Kota Formation, Andhra Pradesh, India. These finds prove a considerable similarity between the Gondwanan and Laurasian hymenopteran faunas during the Jurassic, as well as during the Triassic and Cretaceous.     

New mayfly nymphs from the Jurassic of Northern and Northeastern China (Insecta: Ephemeroptera)

Four new species of mayfly nymphs, Furvoneta relicta sp. nov., Clavineta eximia sp. nov. (originally Mesoneta antiqua), Mesobaetis latifilamentacea sp. nov., and Stackelbergisca cylindrata sp. nov. are described from the Jurassic of China. All these species may have inhabited lakes rather than flowing water. The geological age and stratigraphical correlation of the nymph-bearing strata are briefly reviewed.     

New Ephialtitidae (Insecta: Hymenoptera) from the Jurassic Daohugou Beds of Inner Mongolia,China

Five new species are described from the Middle–Upper Jurassic Daohugou Beds of Inner Mongolia, China, and assigned to the genus Karataus Rasnitsyn, 1977 in the subfamily Symphytopterinae of Ephialtitidae. They are illustrated as Karataus daohugouensis n. sp., K. strenuus n. sp., K. vigoratus n. sp., K. exilis n. sp., and K. orientalis n. sp., and a key to species of Karataus is presented.     

New Insects (Insecta: Trichoptera,Reculida, Eoblattida) from the Mesozoic of Asia

New caddisflies, reculid and eoblattid insects from the Mesozoic of Asia are described. Caddisflies of the families Philopotamidae (Mesoviatrix paradoxa gen. et sp. nov. and Kempia piotri gen. et sp. nov.) and Polycentropodidae (Polylongevus eskovi gen. et sp. nov.) from the Upper Jurassic–Lower Cretaceous of the Kempendyai locality in Yakutia are described. A short review and comparison of fossil members in these families are provided. New Gryllones insects, Shurabia tanga sp. nov., Sauk batkenicus gen. et sp. nov. from the Sauk Tan’ga locality (Lower Jurassic of Kyrgyzstan), Say kirgizicus gen. et sp. nov. from the Shurab III locality (Reculida: Geinitziidae; Lower or Middle Jurassic of Kyrgyzstan) Griphopteron iya sp. nov. (Eoblattida: Blattogryllidae) from Iya locality (Middle Jurassic of Russia) are described.     

Phylogeny of Oestridae (Insecta: Diptera)

The phylogeny of Oestridae was analysed at the generic level using 118 characters from all developmental stages and including morphology, ontogeny, physiology and behaviour. Four major clades were given subfamilial rank with the phylogenetic relationship (Cuterebrinae (Gasterophilinae (Hypodermatinae + Oestrinae))). The subdermal parasites of the African elephant, Neocuterebra squamosa Grünberg and Ruttenia loxodontis Rodhain, had their most probable affiliation subordinate to the clade of stomach parasites, although their exact position needs further investigation. Genus Ochotonia Grunin, which is known from a single third‐instar larva only, was the probable sister group of all other Hypodermatinae. Twenty‐five oestrid genera were recognised as valid and those containing more than one species were defined through lists of autapomorphies. Cuterebra Clark was proposed as a senior synonym of Alouattamyia Townsend, Andinocuterebra Guimarães, Pseudogametes Bischof and Rogenhofera Brauer. The clade of hypodermatine ungulate parasites (Hypoderma Latreille +Pallasiomyia Rubtzov +Pavlovskiata Grunin +Przhevalskiana Grunin +Strobiloestrus Brauer) remained largely unresolved, and genus Przhevalskiana emerged without defining characters.     

Phylogeny of Ptychopteroidea (Insecta: Diptera)

A phylogenetic tree is proposed for the superfamily Ptychopteroidea, reconstructed taking into account both extinct and extant taxa and based mainly on characters of wing venation.     

New and little-known grylloblattids of the family Geinitziidae (Insecta: Grylloblattida) from the Triassic and Jurassic of Europe,Asia, and South Africa

The fossil history of the family Geinitziidae is reviewed. New taxa are described in the family: Shurabia hissarica, sp. nov. (Lower Jurassic of Tajikistan), Sh. shartegica, sp. nov. (Upper Jurassic of Mongolia), Sh. serrata, sp. nov. and Ginitzia sagulensis, sp. nov. (both Lower Jurassic of Kyrgyzstan). The subfamily Stegopterinae Sharov, 1961 is synonymized under Geinitziinae Handlirsch, 1906. The genera Minesedes Fujiyama, 1973 and Ominea Fujiyama, 1973 (Upper Triassic of Japan) are synonymized under Shurabia Martynov, 1937 and Geinitzia Handlirsch, 1906, respectively. Geinitzia varia Bode, 1953 (Lower Jurassic of Germany) and Fletchizia picturata Riek, 1976 (Upper Triassic of South Africa) are redescribed from their holotypes. F. kapokraalensis Wappler, 2001 and F. aleda Wappler, 2001 (both Upper Triassic of South Africa) are transferred to the genus Shurabia.     

New Chironomidae (Diptera) with elongate proboscises from the Late Jurassic of Mongolia

Four new species of Chironomidae with well-developed elongate proboscises are described from a Late Jurassic site Shar Teg in SW Mongolia. These are named Cretaenne rasnicyni sp. n., Podonomius blepharis sp. n., Podonomius macromastix sp. n., ?Podonomius robustus sp. n.     

Proptychopterina (Diptera: Eoptychopteridae) from the Jurassic of Northeastern China

A complete well-preserved male fly from the Jurassic of Daohugou locality (Northeastern China) is described as Proptychopterina opinata sp. nov. The distribution of Proptychopterina is discussed, this genus is re-diagnosed, and a key to species is provided based on the wings.     

The genera of Diopsidae (Insecta:Diptera)

Taxonomic characters which have been used in defining the genera of Diopsidae are discussed with special reference to the structure of the head and eyestalks. In consequence, the subdivisions of this family put forward by Hennig in 1965 are revised and extended, a new scheme of three subfamilies being proposed and a possible phylogenetic sequence of genera suggested.
A key for the identification of these subfamilies and current generic taxa is given.
