Aeshna shennnong sp. nov. (holotype male: Dajiuhu national wetland park in Shennongjia National Nature Reserve, Shennongjia City, Hubei Province, China, 28. VIII. 2013) is described, illustrated and compared with its most similar congener, A. petalura Martin, 1908. The holotype will be deposited in the Collection of Aquatic Animals, Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan ...

Two new species of the genus Devadatta Kirby, 1890, D. kompieri sp. nov. from northern Vietnam (holotype: male, Mu Cang Chai district, Yen Bai Province) and D. yokoii sp. nov. from central Laos (holotype: male, Vang Vieng, Vientiane Province) are described. These new species are allied to D. ducatrix Lieftinck, 1969, but are distinguished by specific characteristics of their wings and anal appe...

The holotype of Malerisaurus langstoni from the Late Triassic (Otischalkian) Trilophosaurus quarry 2 of West Texas is a chimera. The holotype represents at least 6-7 individuals of four reptilian groups: Trilophosauridae, Rhynchosauridae, Parasuchidae and Aetosauria. The majority of the material, including all of the cranial fragments, are re-identified as Trilophosaurus buettneri. Based on the...

A new species of Planaeschna McLachlan, P. guentherpetersi sp. nov. (holotype male and paratype female) from Phu Tho province, northern Vietnam, is described and illustrated. In addition, the male of P. tomokunii Asahina, 1996, which was known from only the holotype female, is described for the first time, based on newly collected material of both sexes, from the type locality, Tam Dao, Vinh Ph...

Plesiochelyidae are a major component of Late Jurassic shallow marine environments throughout Europe. However, the taxonomy of plesiochelyid turtles is rather confused. Over the years, many taxa have been synonymized with Plesiochelys etalloni, one of the first described species. However, the holotype of P. etalloni (and only specimen known from Lect, the type locality) was lost for more than 1...

When describing the new species Unixenus corringlensis Short & Huynh, sp. n., the latitude given for the single collecting event of this species in Corringle state forest is incorrect and should be 33°40'00"S not 33°22'12"S. The correct wording in the species description for the holotype, a male paratype and two specimens included as other material is as follows: Holotype. Female, Corringle Sta...

　Heteragrion is the most speciose and complex genus of neotropical Megapodagrionidae, with 47 species and one subspecies, and many of them are poorly defined. To improve the knowledge of the Brazilian species of the genus, 179 specimens of 13 of the 17 described species were examined. Four new species are described in tribute to the 40 thanniversary of the rock band Queen: Heteragrion freddieme...

The South African species Euparkeria capensis is of great importance for understanding the early radiation of archosauromorphs (including archosaurs) following the Permo-Triassic mass extinction, as most phylogenetic analyses place it as the sister taxon to crown group Archosauria within the clade Archosauriformes. Although a number of species from Lower-Middle Triassic deposits worldwide have ...
