Mitochondrial genome analyses reveal how tectonic uplift in the Tien Shan Mountains shaped snow trout evolution and biodiversity in Central Asia.

Snow trout (Schizothorax), endemic to the high-altitude freshwater systems of the Tibetan Plateau and the Tien Shan Mountains region, are key components of these ecosystems. This fish lineage may serve as an appropriate model to understand the evolution of biodiversity in the Tien Shan Mountain wate...

Researchers present a new fossil species of the genus Provanna from gas hydrate-bearing sediments in the cold seep area of the northern South China Sea.

The genus Provanna (belonging to Superfamily Abyssochrysoidea) is a group of globally distributed gastropods commonly discovered in the deep-sea chemosynthetic environments. To date it is composed of 29 extant and nine fossil species and all of them seem to be endemic to vents, seeps or organic fall...

Using mitochondrial phylogenomics and morphology, researchers describe a new species of freshwater mussel, Nodularia guiensis, discovered in Guangxi, China.

The genus Nodularia poses a significant challenge to traditional species classification and identification due to its highly convergent and variable shells, rendering it one of the most intricate groups within the family Unionidae. Fortunately, significant progress has been made by researchers in re...

Researchers have rediscovered the centipede genus Agnostrup in China, redescribing a species and synonymising the genus Nannarrup with Agnostrup.

The genus Agnostrup Foddai, Bonato, Pereira & Minelli, 2003 is one of the least known genera within the family Mecistocephalidae Bollman, 1893. In this study, we rediscovered the genus Agnostrup in China and provided a comprehensive redescription of A. striatus (Takakuwa, 1949). Additionally, we...
