これまで単一種と考えられてきたヒマラヤハブが、実際には5つの独立した種で構成されており、そのうち3種は科学的に新種であることが研究チームによって特定されました。この発見は、遺伝子解析および博物館の標本調査を通じてなされたものです。
国際研究チームは、1864年に初めて記載されたこの毒蛇の再分類を行いました。学術誌「ZooKeys」に掲載された彼らの研究では、現代の遺伝子解析技術と、パキスタンおよびネパールで収集された骨格的特徴や生態学的データの調査が組み合わされました。
Researchers have identified a new venomous pitviper species in the misty mountains of western Sichuan, China, previously mistaken for a common snake. Named Trimeresurus lii after the philosopher Laozi, the Huaxi Green Pitviper features distinct markings and eye colors between males and females. DNA analysis confirmed its unique evolutionary lineage in a global biodiversity hotspot.

Scientists have identified a new insect species preserved in 100-million-year-old amber from Myanmar. The true bug features unusual front legs ending in large claw-like structures similar to crab pincers. Researchers named it Carcinonepa libererrantes after the K-pop group Stray Kids.
Researchers at the Kenya Medical Research Institute (KEMRI) have issued a warning after detecting a new Anopheles mosquito species in urban areas. This mosquito prefers human-made environments and could heighten malaria risks in cities. Monitoring efforts continue across several counties.
