A new species, Cimbrophlebia rara sp. nov., in the family Cimbrophlebiidae (Mecoptera) is described and illustrated. This specimen was collected from the Early Cretaceous Yixian Formation at Liutiaogou in Inner Mongolia, China. This is the first record of a cimbrophlebiid from the Jehol biota. A key to all species of Cimbrophlebia is given. A preliminary review of published taxa data indicates that from the Middle Jurassic to the Early Cretaceous, Mecoptera became less diverse and less abundant in northeastern China at familiar level (from 11 to 6), generic level (from 32 to 8) and specific level (from 44 to 14).

A new genus and species of campterophlebiid dragonfly,Angustiphlebia mirabilisgen. nov. et sp. nov., is described from the Jiulongshan Formation in China. It has some remarkable venational structures, i.e. a hypertrophy of the male hind wing anal angle, a quite long gaff, and a secondary branch of the anal anterior near subdiscoidal cell in hind wing, supporting the hypothesis of a sister-group relationship with the genusOreophlebia. These new data will help to solve the phylogenetic relationships within the Campterophlebiidae.http://www.zoobank.org/urn:lsid:zoobank.org:pub:16E602E6-3567-44D7-BF64-95A6597E55DE [ABSTRACT FROM AUTHOR]

A new species of a new genus, Atopderma ellipta gen. et sp. nov. is described from the Middle Jurassic Jiulongshan Formation of Daohugou, Inner Mongolia, China. Because of poor preservation, the placement of these specimens is contentious, either Dermaptera or Coleoptera. However, we are inclined to attribute them to Dermaptera based on differences of five key characters. Detailed description and illustration of the specimens are given. Possible reasons for lacking good and complete abdomen preservation are also discussed. [ABSTRACT FROM AUTHOR]

Jurassonurus amoenus, a new genus and species of Siphlonuridae s. l. is described from the Middle Jurassic Jiulongshan Formation of the Daohugou Village, Shantou Township, Ningcheng County, Inner Mongolia, China. The new species is established by more than 20 imago and subimago specimens in relatively good condition. Detailed description and illustration of the specimens along with a review of fossil Siphlonuridae s. l. are given. Comparing with two known dominant nymph species Fuyous gregarious Zhang and Kluge, 2007 and Shantous lacustri Zhang and Kluge, 2007 from the same locality, we could not find any relationship among them. The new species is another dominant species in Daohugou beds. [ABSTRACT FROM AUTHOR]

Abstract: Two fossil dragonflies from the Upper Jurassic to Lower Cretaceous Yixian Formation in Liutiaogou Village, Ningcheng County, Inner Mongolia, China are described and illustrated. They are assigned to two new genera and species, i.e., Sophoaeschna frigida gen. et sp. nov. and Falsisophoaeschna generalis gen. et sp. nov. within the family Gomphaeschnidae Tillyard & Fraser, 1940. This is the first report of Odonata from Yixian Formation in Inner Mongolia and the second record of fossil Gomphaeschnidae from China. [Copyright &y& Elsevier]

Three new species, Grammolingia uniserialis n. sp., Grammolingia binervis n. sp., and Grammolingia sticta n. sp. are described from the Jiulongshan Formation of northeastern China. G. uniserialis n. sp. exhibits a single row of cells in the costal area almost along the entire wing length except the basal part, which is rare in the family and firstly found in this genus. G. binervis n. sp. and G. sticta n. sp. add two new patterns of wing markings to the family. A key to the species of Grammolingia Ren, 2002 is provided. All types of wing markings present in this family are classified. (© 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) [ABSTRACT FROM AUTHOR]

Abstract: A new genus with a new species of fossil elaterid, Paraprotagrypnus superbus gen. et sp. nov., from the Middle Jurassic Jiulongshan Formation in Daohugou Village (N41°18.979′, E119°14.318′), Shantou Township, Ningcheng County, Inner Mongolia, China is described and illustrated. The genus Paraprotagrypnus belongs to the family of Elateridae, subfamily of Protagrypninae and tribe of Protagrypnini. Some primitive characters of the new genus and new species shed light on the ages between the Jiulongshan Formation in Inner Mongolia and the Yixian Formation in the western Liaoning Province of China. The habitat of the new species is briefly discussed. [Copyright &y& Elsevier]

Abstract: A new genus and new species, Juraphilopotamus lubricus gen. et sp. nov., from the Middle Jurassic Jiulongshan Formation of Daohugou, Inner Mongolia, China, is described and illustrated. It may be the first record of the family Philopotamidae in China, extending the geographic distribution of this family. A detailed description and illustration of the specimen along with a brief review of the fossil Philopotamidae are given. A proposal on dispersion and migration of Philopotamidae and problems of the paleoenvironment of the Daohugou beds are discussed. [Copyright &y& Elsevier]
