A New Species

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.

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.

A New Species

A new species Karatawia sinica Li, Nel et Ren, sp. nov. is described from the Middle Jurassic Jiulongshan Formation, and compared with the other species of this genus. As it is based on a new fossil with fore- and hindwings preserved, it confirms the attribution of Karatawia sibirica to this genus, of Karatawia to the Campterophlebiidae, and the synonymy of the Karatawiidae with this family. Otherwise, the two other species K. mongolica and K. shurabica, which are based on more incomplete specimens, are more properly to be considered as Campterophlebiidae incertae sedis.

A New Species

Study of isolated leaf compressions from Prisayan Formation outcrops on the right side of the Irkutsk reservoir resulted in identification of a new species: Marskea cuspidata sp. nov. The species has a strong morphological affinity with M. heeriana N. Nosova et Kiritchkova and T. ketovae Teslenko. The epidermis original texture differs well the Marskea cuspidata sp. nov. from other representatives of the genus Marskea which are known from the Jurassic and Lower Cretaceous sediments of Europe, Central Asia and Siberia.

Palaeontinodes reshuitangensis sp. nov., a new species of the Mesozoic family Palaeontinidae, is described based on some well-preserved specimens from the Middle Jurassic of Reshuitang and Daohugou of China. Palaeontinodes cf. angarensis Becker-Migdisova & Wootton, 1965 (sensu Wang, Zhang & Fang, 2006) is transferred to P. reshuitangensis. This discovery indicates that fossil-bearing strata of Daohugou and Reshuitang are contemporaneous. A key to species of the genus Palaeontinodes is presented.
