New Records of Petrified Wood from the Middle Jurassic in Ar Horqin Banner, Inner Mongolia

ABSTRACTThe genus Orthobittacus was established by Willmann (1989) and is characterised by a long Sc vein and the unusually developed medial sector for the Bittacidae. Four Jurassic species have been described in this genus to date: O. abshiricus (Martynova, 1951) from Kirgizia; O.desacuminatus (Bode, 1953) from Braunschweig (Germany); O. polymitus Novokshonov, 1996 from Karatau (Kazakhstan); and O. maculosus Liu, Shih, Bashkuev & Ren, 2016 from the Jiulongshan Formation of Daohugou (China). The fifth congeneric and second species from China, O. suni sp. nov., is described herein. The importance of the genus Orthobittacus for the phylogeny of Bittacidae, as the most plesiomorphic genus, is discussed.

A New Species

A new species of Ripiphoridae Gemminger & Harold, 1870, Archaeoripiphorus nuwa gen. et sp. nov., is described and illustrated from a well-preserved impression fossil from the Middle Jurassic Jiulongshan Formation collected at Daohugou Village, Shantou Township, Ningcheng County, Inner Mongolia, China, representing the oldest documented occurrence of the Ripiphoridae described from the Mesozoic era. It shares several characters belonging to two basal ripiphorid subfamilies (Pelecotominae and Ptilophorinae), but it cannot be attributed to either of them and is herein placed as Subfamily incertae sedis. An overall similarity between Archaeoripiphorus gen. nov. and Recent Pelecotominae and the occurrence of wood-boring beetles in the same Formation implies a similar parasitoid host preference in xylophagous beetles for A. nuwa gen. et sp. nov., putting a spotlight on a potential host-parasitoid relationship in the Mesozoic.

Two new species, Itaphlebia exquisita sp. nov and Itaphlebia laeta sp. nov., were collected from the Jiulongshan Formation (Middle Jurassic) of Daohugou, Inner Mongolia, China. A key to the species of the genus Itaphlebia is provided and diagnosis of the genus is revised. Itaphlebia exquisita sp. nov differs from other species in having an extra medial vein branch. Itaphlebia laeta sp. nov shows a transitional character to the extant genera by having a simple Sc. These new findings expand the distribution of Itaphlebia from middle-southern Russia to northeastern China.

A New Species

A new species of the family Grammolingiidae (Neuroptera) (Leptolingia imminuta sp. nov.) is described from Daohugou village (Middle Jurassic), Inner Mongolia, China. In this new species, MA forks at the same level as the separation of Rs2 from Rs, close to the middle of forewing, this structure of MA is peculiar in Grammolingiidae and is different from that of all other known species. Moreover, this new species is the smallest species known in the family Grammolingiidae (30 mm wing span).

A New Species

A new genus with a new species (Jurachresmoda gaskelli gen. et sp. nov.) of Chresmodidae (Insecta: Polyneoptera: Orthopterida) is described and illustrated. They were collected from the Middle Jurassic in Daohugou, Jiulongshan Formation, Inner Mongolia (Nei Mongol Autonomous Region), China. J. gaskelli have fringing hairs on tarsi and a part of tibiae of mid legs. These hairs and leg structures were probably associated with its water-skiing locomotion on freshwater. A high number of tarsomeres, e. g. ultra-articulated tarsi as reported in other species of Chresmodidae, are also found for this new species. But, these true tarsi are mixed with some wrinkles resulted from dehydration and compression during fossilization process. Nymphs of the new species are also described. This is the first time that long and segmented cerci of the nymph are described in Chresmodidae.

The new aeshnopteran genus and species Sinocymatophlebiella hasticercus is described from the Middle Jurassic Jiulongshan Formation of Inner Mongolia. It shows important similarities with the Jurassic genus Cymatophlebiella from Karatau, suggesting they could belong to the same family, but the latter genus is too poorly known to accurately establish its affinities. The present discovery supports the evolutionary scenario of a Jurassic rapid and massive diversification of the Aeshnoptera, followed by important extinctions during the Late Mesozoic.

Two new genera and new species, Peregrinpachymeridium comitcola gen. et sp. nov. and Corollpachymeridium heteroneurus gen. et sp. nov., of fossil Pachymeridiidae are described and illustrated from the Middle Jurassic Jiulongshan Formation in Daohugou Village, Shantou Township, Ningcheng County, Inner Mongolia Autonomous Region, China. We summarized all fossil genera of pachymeridiids found in China and set up a key to these 7 genera and 7 species. In addition, we hypothesize the significance of a rare, well-preserved, unusual bug fossil showing a male and a female together with their abdomen terminalia facing each other and their heads in the opposite direction.
