More details about the news:
- The new species, named Cliffside Bambootail (Phylloneura rupestris), belongs to a group called bambootails, so named because of their long abdomen that resembles bamboo stalks.
- The discovery is significant, because for over 160 years, the genus Phylloneura was considered monotypic, with a single described species, the Myristica Bambootail (Phylloneura westermanni).
- To date, it has remained the sole described species of the genus Phylloneura and is considered near-threatened as per the IUCN Red List of Threatened Species.
- It is endemic to the Western Ghats and has been recorded only in the area between the Nilgiri Hills and Sharavathi Valley, north of the Palghat Gap.
- Cliffside Bambootail has been named thus because it lays eggs in the moss beds in seasonal rillsthat flow over rock cliffs. This behaviour is in contrast to that of Myristica Bambootail that lays its eggs on the surface roots of riparian trees.
