The Campterophlebiidae is the largest family of fossil damsel-dragonflies, containing more than 60 species described from Lower Jurassic–Lower Cretaceous strata of Europe and Asia. This group is especially diverse in the Middle–Late Jurassic strata in Inner Mongolia, northeastern China, with some very large species (Zhang et al., 2006, 2008, 2013; Nel et al., 2007, 2008, 2009; Petrulevičius et al., 2011; Li et al., 2013; Zhang et al., 2013; Zheng et al., 2016, 2017). Thus it is surprising that we found a new representative of these damsel-dragonflies, belonging to a group of genera characterized by a very particular shape of the forewing cubito-anal area. This fossil has a unique shape of the forewing median vein, allowing its attribution to a new genus and species. It increases our knowledge about the palaeobiodiversity of this impressive group of Odonata.

AbstractA new genus and species, Aclemus patulus n. gen. n. sp., is described based on a new specimen collected from the latest Middle Jurassic Jiulongshan Formation in Inner Mongolia, China. Based on a combination of characters from this fossil, including a homonomous fore- and hindwing, a 3-branched media vein, wings lacking long cilia on their margins; and a cross-vein absent between subcosta and radius, we establish a new genus assigned to the Eolepidopterigidae. In addition, the diagnosis of Longcapitalis excelsus Zhang, Shih, Labandeira and Ren 2013, is emended based on new fossil material.

A new genus and species of rhagionids with a long proboscis, Elliprhagio macrosiphonius gen. et sp. nov., is described from the Middle Jurassic Jiulongshan Formation in Daohugou, Inner Mongolia, China, which is considered to be the earliest hematophagous rhagionid described hitherto according to the typically piercing and sucking mouthparts. All previously documented rhagionids from northeastern China are reviewed a key to genera of Rhagionidae from Daohugou is provided for the first time. The genus Daohugorhagio Zhang, 2013 is considered as a new synonym of Trichorhagio Zhang, 2013.

Jiulongshan Formation

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.

A new genus and species of primitive cryptodiran turtle, Siamochelys peninsularis n. g. n. sp., from the Middle Jurassic Mab Ching locality, in the southern peninsula of Thailand, is described on the basis of complete shells. They are characterized by a combination of primitive features (the presence of a pair of mesoplastra meeting on the midline) and a series of derived characters (loose plastron–carapace attachment, short diamond-shaped entoplastron, dorsal thickening of the lateral edge of the second to seventh peripheral plates, expanded seventh to eleventh peripheral plates, extension of the anal scute to the hyo-hypoplastral suture or onto the hypoplastron, midline sulcus sinusoidal), and thus closely resemble Chengyuchelys, from the Middle Jurassic of China, and more particularly Xinjiangchelys and its relatives from the Middle and Late Jurassic of China and Central Asia. This supports a Middle Jurassic age for the locality and suggests that the Sibumasu (Shan-Thai) block was in contact with the Asian mainland by that time.

A new genus and species of Mesoserphidae (Hymenoptera), Juraserphus modicus gen. et sp. nov., is described based on a well-preserved fossil specimen from the Middle Jurassic Jiulongshan Formation of northeastern China. It is characterized by the following forewing features: the forking of Rs+M located approximately one-third of the distance between 1m-cu and 2r-rs, both 1cu-a and 2cu-a antefurcal; 1-M more than twice as long as 1m-cu and hind wing with cells r and rm closed. In addition, it has a short ovipositor, only extending slightly beyond the metasomal apex. Its new morphological characters broaden the diversity of Mesoserphidae in the Mesozoic and provide new insights into the evolution and relationships of Mesoserphidae.

A new genus and species of Ithonidae, Puripolystoechotes pumilus gen. et sp. nov., is described from the Middle Jurassic of Inner Mongolia, China. The new genus is distinguished by possessing a hind wing with a simple humeral vein, only three ra-rp crossveins, M forked slightly distal to origin of RP1, and wing membrane without color pattern. This is the third ithonid genus from this locality, showing interesting morphological similarity with the other ithonids from the same locality and period.

AbstractBaissogryllidae is an extinct family of the insect superfamily Grylloidea, previously known from Late Jurassic – Early Cretaceous time. A new genus and species, Sinagryllus xinjiangensis gen. et sp. nov., is described here based on a well-preserved forewing from the Lower Jurassic Sangonghe Formation of Xinjiang, northwestern China. It can be attributed to Baissogryllidae based on the combination of the following characteristics: a true mirror in the male tegminal stridulatory apparatus; and a distinct widening of the area between CuA2, lateral part of the diagonal vein, and proximal part of the proximal branch of MP+CuA1. This find represents not only the earliest record of Baissogryllidae, but also the first fossil wing of Grylloidea reported from China.

The first fossil bee in Eocene amber of the Fushan Coalfield, Liaoning, China is described and figured.  Exebotrigona velteni Engel & Michener, new genus and species (Apinae: Meliponini) is based on a stingless bee worker and is remarkably similar in several apomorphic traits to the species of the New World genus Trigonisca Moure s.l.  The diversity of fossil and subfossil Meliponini is briefly summarized, as are the characters and possible affinities of Exebotrigona.
