The Asian frog genus Megophrys is a diverse group of morphologically conserved, forest-dwelling frogs. The genus harbours highly localised species diversification and new species continue to be described on a regular basis. We examined the taxonomic status of a population of Megophrys frogs from the Hoang Lien Range in northern Vietnam and southern China previously identified as M. kuatunensis (subgenus Panophrys). Preliminary phylogenetic analyses using a fragment of 16S rDNA places the species in question within the Megophrys (subgenus Panophrys) species group, a primarily Chinese radiation within the genus. On the basis of morphological, molecular and bioacoustic data, we conclude that this population does not represent M. kuatunensis, or any known species in the genus. We herein describe this species of Megophrys as new. Known only from Sa Pa District, Lao Cai Province in Vietnam and Jinping County, Yunnan Province in China, the new species is likely to be threatened by ongoing deforestation in the region. We provide an updated species description of M. kuatunensis based on type specimens, and suggest that M. kuatunensis is likely to be restricted to eastern China.

A new species, Strobilomyces rubrobrunneus, is described from eastern China based on morphological and molecular evidence. Morphologically, this species is characterized by its tiny to small basidiomes, reddish-brown and more or less erect pyramidal scales, grayish black discoloration of the pileal context when bruised, reticulate spores and a subtropical distribution in a mixed forest of Fagaceae and Pinaceae. Our phylogenetic analyses based on four gene markers (rpb1, rpb2, tef1 and cox3) support its placement in Strobilomyces and its separation from other related species of this genus. Morphological illustrations and description are provided.

Hilliella rhombea, a new species of Brassicaceae from Zhejiang, eastern China is described and illustrated. It is similar to Hilliella fumarioides (Dunn) Y. Z. Zhao, but can be distinguished from the latter fruit rhombic, valves membranous, glabrous or sparsely papillate.

Amana wanzhensis, a new species from Ningguo County, Eastern China, is described and illustrated. A. wanzhensis is similar to A. erythronioides in sharing villous tunics and oblanceolate leaves, but differs from it by having shorter bracts (0.1–0.5 cm long), yellow anthers, and deciduous tepals.

AbstractA new species of the extinct rove beetle genus Hesterniasca Zhang, Wang & Xu, 1992 is described and illustrated on the basis of a well-preserved specimen from the Lower Cretaceous Yixian Formation at Huangbanjigou of Beipiao City, Liaoning Province, Northeastern China. Based on the examination of this new species that is preserved better than the type species of the genus, Hesterniasca is firmly placed in the recent subfamily Tachyporinae, tentatively in the recent tribe Tachyporini MacLeay, 1825. Arguments for the Early Cretaceous age of the Laiyang Formation in Shandong Province, Eastern China, from where the type species of the genus, Hesterniasca obesa Zhang, Wang & Xu, 1992, has been discovered are provided.

A lower molar of a new species of rodent, Prosciurus? shantungensis, from the subsurface of eastern China adds to the diversity of the known Asian prosciurine aplodontids and increases the likelihood that aplodontids were widespread in Eurasia during the Oligocene. This form is structurally close to the North American prosciurine aplodontids, especially Prosciurus relictus from the middle Oligocene. The metaconid is strongly compressed and reduced in height, a condition partially developed in P. relictus but here more extreme. Height of the mesoconid and the degree of lophodonty are more advanced than in North American species of Prosciurus. P.? shantungensis differs from the prosciurine-like lower dentitions from Kazakhstan and Mongolia described by Argyropulo (1939) and Kowalski (1974) in crest development and in details of the cusp morphology. Types of the Asian prosciurine or presumed prosciurine species are upper dentitions for which associated lower dentitions are unknown, yet the slope of the crests in Prosciurus lohiculus is too low to match the occlusal surface in P.? shantungensis and the degree of lophodonty in P. arboraptus is less than would be expected for the upper dentition of the Shantung form.
