The Yanghecun specimen, a proboscidean specimen represented by a mandible from Miocene of China and previously described as Gomphotheriidae, is here reviewed and described as a new genus and species of Mammutidae: Sinomammut tobieni. This taxon is a longirostrine mastodon, lacking lower tusks, and bearing a wide last molar with oblique and non-inflated lophids, broad transverse interlophids, and yoke-like wear figures. Phylogenetic analysis of Mammutidae based on dental and mandibular features recovered S. tobieni as sister group of the mastodon Mammut. The longirostrine condition and the well-developed lower incisors seem to be primitive for Mammutidae, while the brevirostry is the derived condition, probably emerged during the middle Miocene (12-11 Mya). However, two derived conditions are recognized to the lower tusks: the absence of lower tusks (S. tobieni) and the occasional presence of vestigial lower tusks (Mammut).

Plesiohipparion is a genus of hipparionine horses that first appears in the latest Miocene of SW Tibet and becomes a common equid in the Pliocene of China. Plesiohipparion is distinct from the late Miocene clades Hippotherium, Hipparion, Cremohipparion and Sivalhippus and is related to the Chinese Proboscidipparion and African Eurygnathohippus. Plesiohipparion extended its range into Turkey, southwest Europe and Arctic Canada during the Pliocene. Plesiohipparion shanxiense n. sp. is the largest, and at the same time the youngest species of the genus. Plesiohipparion shanxiense n. sp. is most closely related to the earlier, smaller species Plesiohipparion houfenense differing in size, length of snout, length of the cheek tooth row, lack of any preorbital facial structures and elongate, narrow structure of the I3. Whereas Plesiohipparion likely originated in China, it dispersed westward to Turkey and Spain. Plesiohipparion is likely the sister taxon of the African Eurygnathohippus based on a number of shared-derived characters. Plesiohipparion shanxiense n. sp. would appear to be restricted to China and the terminal species of this clade. © 2015, Mucchi Editori s.r.l. All rights reserved.

We describe and compare three partial skulls of Chinese juvenile Proboscidipparion sinense from the Nihewanian of China. Study of the facial morphology, especially the nasal aperture, as well as cheek tooth morphology and metric data, including length versus width of the maxillary cheek teeth of dP2, 3 and 4, support the conclusion that these skulls are referable to Proboscidipparion sinense. We reaffirm that Proboscidipparion sinense is a member of the "Sivalhippus" Complex that includes the following superspecific clades: Sivalhippus, Eu-rygnathohippus, Plesiohipparion and Proboscidipparion. Recent studies by Bernor and Sun (2015) suggest that Proboscidipparion is particularly closely related to Chinese Plesiohipparion, and more distantly related to Eurygnathohippus (exclusively Africa) and Sivalhippus (mostly South Asia).

This paper describes new fossils of Equus huanghoensis from an Early Pleistocene bed in Nihewan, Hebei Province, which confirms the classification of E. huanghoensis by Chinese researchers. The new fossils include a relatively complete male skull and mandible with all upper and lower dentition, a broken female skull with fragment of mandible and a broken Mc III of Equus sp. The fossils were collected from the Yangshuizhan site of Nihewan. The age of the formation is about 1.6 Ma. The new materials verify some classification characteristics based on teeth published in previous descriptions. These characteristics include large teeth size, short protocone, and tilted protoloph and metaloph. We have added to these characteristics of large skull size, a developed protuberantia supramagna, pentagonal nuchal side, weak Pli cabaline, simple enamel plications; a series of new characteristics strikingly different from the other Equus horses. The broken Mc III is similar to Equus qingyangensis from Qingyang, Gansu © 2015 Science China Press and Springer-Verlag Berlin Heidelberg


Colorifuzia agenora n. gen., n. sp., attributed to the family Fuziidae Vršanský, Liang & Ren, 2009 is described from the Middle Jurassic of Jiulongshan Formation in Daohugou Village (Inner Mongolia, China). The new species is the first representative of the family with distinct pattern of coloration, indicating Fuziidae was able to adapt to diverse environments in this locality during the Middle Jurassic. Plesiomorphic characters such as considerably wide body, fore-wing large, coloration markings suggest Colorifuzia n. gen as a comparatively plesiomorphic taxon among Fuziidae. © Publications Scientifques du Muséum national d'Histoire naturelle, Paris.

A new species attributed to the genus Parvifuzia Guo & Ren, 2011, Parvifuzia peregrina sp. n., is described from the Middle Jurassic Jiulongshan Formation of Daohugou Village, Inner Mongolia, China. This new species, with apex of wing almost reaching the end of the abdomen and forewing venation with 30-32 veins at margin, broadens the diversity of Parvifuzia. This new species, with strongly curved cerei, could tightly clasp female and complete copulation more efficiently, same as other members of the family Fuziidae. © Dandan Wei et al.

Graciliblatta bella Liang, Huang et Ren, gen. et sp. n. is described from the Middle Jurassic Jiulongshan Formation of Daohugou in Eastern Inner Mongolia, China. Vein Sc of the new taxon has up to eight distinct branches, a remarkable diagnostic feature that distinguishes it from the other five known genera of the Raphidiomimidiae. The species was either extraordinary rare or lived remotely from the source area. It significantly expands the knowledge on diversity of carnivorous cockraoches - the least known cockroaches.

A new genus of Middle Jurassic cockroach belonging to the family Liberiblattinidae viz., Entropia gen. nov., with a new species E. initialis sp. nov., is described from the Bathonian sediments of the Daohugou in Inner Mongolia, China. This species has multiply deformed wings supporting the rapid evolution of this group during the Middle Jurassic. Voucher specimen is deposited with the Capital Normal University in Beijing. © 2012 Taylor & Francis.
