A new beetle species Notocupes pingi sp. nov. (Coleoptera: Cupedidae) is described from the well-known fossil site of Daohugou. With more than fifty species, Notocupes is the biggest Mesozoic genus of beetles but had not been previously found at this locality.
A new genus including two new species of fossil cupedids, Latocupes fortis gen. and sp. nov. and L. bellus gen. and sp. nov., is described from the Yixian Formation of western Liaoning Province, China and assigned to family Cupedidae. A brief morphological analysis shows that the new genus might be sister group of extant genus Priacma.
The first Chinese fossil of the family Nymphidae (Neuroptera: Myrmeleontiformia) is briefly described and figured along with two episomyline Osmylidae, a generally plesiomorphic group which can be easily confused with nymphids when only wings are known. Four new species and three new genera are characterized from Jurassic deposits of the Jiulongshan Formation (Daohugou Biota), Inner Mongolia, China. New genera are Liminympha (Nymphidae), Eiwdinympha (Osmylidae), andNilionympha (Osmylidae), while the new species are Liminympha makarkini, Enodinympha translucida, Nilionympha pulchella, and N. imperfecta.
A new genus and species of Baleyopterygidae, Aristoleuctra yehae gen. and sp. nov. collected from the Middle Jurassic of Daohugou Village, Shantou Township, Ningcheng County, Inner Mongolia, China, is described and illustrated. This is the first report of Baleyopterygidae from China. With the establishment of Aristoleuctra, Baissoleuctra conspecta Sinitshenkova, 1992 from Late Jurassic - Early Cretaceous of East Siberia is transferred to this genus.
A new genus with two new species and one new species of fossil elaterids are described: Paradesmatus baiae sp. nov., Paradesmatus ponomarenkoi sp. nov., Protagrypnus robustus sp. nov. These findings document the fossils from the Middle Jurassic Jiulongshan Formation of Eastern Inner Mongolia, China. Fossil elaterids of Mesozoic with large triangular plates of metacoxae have been discovered only from the Upper Jurassic strata of Karatau so far, Paradesmatus baiae with the unique feature will expand our knowledge on the early diversification of elaterids.
Sinopachymeridium popovi, a new genus and species of fossil true bugs is described. The new species is reported from the Jiulongshan Formation (Middle Jurassic), in Daohugou Village, Shantou Town, Ningcheng County, Inner Mongolia, China. It clearly belongs to Pachymeridiidae by Sc, R and M diverging at a single point and presence costal fracture. The new genus is most similar to Pachycoridium Popov, 1986, but can be distinguished from the latter by the larger body, rostrum extending to second abdominal sternite, first vein of membrane situated remote from anterior margin of fore wing and fourth and fifth veins forming a merged vein.
A new Late Carboniferous cnemidolestodean insect Xixia huban gen. et sp. nov., is described from the Xiaheyan locality (Zhongwei City, Ningxia, China; Tupo Formation). Its combination of character states and observed variants on the wing venations are indicative of homologies shared with more derived members of the order. In particular it is ascertained that MP runs fused with CuA and CuA + CuPa, but is not usually visible as a distinct vein. The new genus exhibits previously unknown coloration pattern composed of dark patches distributed over the whole forewing (as opposed to regular stripes or rows of spots, previously documented in the group). The comparatively abundant sample makes it one of the best documented cnemidolestodeans to date.
One new fossil genus and four new fossil species are described from the Late Tithonian-Berriasian Yixian Formation (Huangbanjigou) in China: Sinosperchopsis silinae gen. et sp. nov., Hydrophilopsia shatrovskiyi sp. nov., H. hydraenoides sp. nov. and H. gracilis sp. nov. (Coleoptera: Hydrophiloidea). The genus Sinosperchopsis is compared with all Mesozoic hydrophiloid genera known so far.
A new genus, Cretodascillus gen. nov. in the family Dascillidae with a new species C. sinensis sp. nov., is described from the Early Cretaceous Yixian Formation of Inner Mongolia, China. The fossil taxa described in Dascillidae have been critically reviewed and the Upper Triassic Apheloodes Dunstan, 1923 (type species A. obliquum Dunstan, 1923) and Leioodes Dunstan, 1923 (type species L. planum Dunstan, 1923) are removed from Dascillidae to Coleoptera incertae sedis, the Miocene Protoacnaeus Wickham, 1914 (type species P. tenuicomis Wickham, 1914) is transferred to Psephenidae and Miocyphon Wickham, 1914 (type species M. punctulatus Wickham, 1914) to Scirtidae.
One new genus including two new species of fossil cupedids assigned to family Cupedidae, Gracilicupes crassicruralis gen. and sp. nov. and Gracilicupes tenuicruralis gen. and sp. nov., is described from the Middle Jurassic Jiulongshan Formation of eastern Inner Mongolia, China.
A new osmylid neuropteran insect Archaeosmylidia fusca gen. et sp. nov. is described from the Middle Jurassic locality of Daohugou (Inner Mongolia, China). Its forewing venation differs from that of other hitherto known osmylids by a set of plesiomorphic features. This genus is considered here as representing a basal group of Osmylidae. The Permian–Triassic family Archeosmylidae comprises the genera Archeosmylus, Babykamenia, and Lithosmylidia. Archaeosmylidia and Archeosmylidae share the few−branched CuP, the absence of zigzag vein pattern, and the scarcity of the crossveins in the radial space.Weestimate that Osmylidae might have originated in the Triassic from some “archeosmylid−like” ancestor.
Three new species Brenthorrhinoides latipecteris sp. nov., B. angustipecteris sp. nov., B. magnoculi sp. nov. within the family Nemonychidae (Coleoptera: Curculionoidea) are described and illustrated. All the fossils were recovered from the Yixian Formation (Late Jurassic or Early Cretaceous) of western Liaoning Province, China. A brief review of fossil nemonychids and a key to species within the genus Brenthorrhinoides are provided. Furthermore, possible host plants to these ancient nemonychids are discussed.
Paradermestes jurassiens gen. et sp. nov., a new dermestid beetle is described based on a well-preserved impression fossil collected from the Middle Jurassic Jiulongshan Formation in Daohugou Village, Shantou Township, Ningcheng County, Inner Mongolia, China, making it the oldest fossil of the family. Based on its size, no visible ocellus and laterally reduced hind coxal plates Paradermestes is placed in subfamily Dermestinae and tribe Paradermestini, trib. nov.
A new fossil lacewing, Tenuosmylus brevineurus gen. et sp. nov., was collected from an outcrop of Middle Jurassic strata in the village of Daohugou, Inner Mongolia, China. The new genus is assigned to Gumillinae based on eleven defining characteristics of the subfamily. The affiliation of Tenuosmylus including other five genera of the subfamily is discussed. Our result supports the opinion that Epiosmylinae was a junior synonym of Gumillinae, which is likely a relic of ancient osmylids based on similarity of forewing venation. Veins Mp₂ and Cu₂ have complicated branches that are generally present in extinct as well as some extant subfamilies (Poriminae, Eidoporisminae, Stenosmylinae). A key is given to differentiate six known genera within Gumillinae.
Macaroblattula ellipsoides gen. et sp. nov., Elisama cuboides sp. nov. and E. extenuata (Ren, 1995) of the dominant cockroach family Blattulidae are described from the Late Jurassic/Early Cretaceous Yixian Formation of western Liaoning in China. Forewing venation of E. extenuata reveals low variation (CV for total number of veins = 6.22), which indicates active flight of this advanced taxon. Presence of Macaroblattula gen. nov. suggests a generic variation and high adaptability of the family. Taxonomic composition supports the transitional Late Jurassic/Early Cretaceous age of the Yixian Formation and dominance of the family Blattulidae within assemblage indicates their significance in food chain.
Two new genera including four new species of fossil beetles assigned to the family Schizophoridae - Menopraesagus explanatus gen. and sp. nov., M. oxycerus gen. and sp. nov., M. grammims gen. and sp. nov. and Homocatabrycus liui gen. and sp. nov., and a new genus including one new species assigned to the family Ademosynidae - Lasiosyrie euglyphea gen. and sp. nov. are described. All of them are collected from the Middle Jurassic Jiulongshan Formation of eastern Inner Mongolia, China. Another two new fossil species referable to the genus Tetraphalerus of family Ommatidae, Tetraphalerus latus sp. nov. and Tetraphalerus curtinervis sp. nov., are reported from the Jehol Biota of western Liaoning, China.
