• The new species is characterized by its white colour, measuring less than 15 millimetres in length, with 13 pairs of legs serving various functions.
• It can be recognized from other similar species by having two to three hair-like structures on the front edge of the gnathopod's propodus(Limb).
• It belongs to the subfamily Platorchestiinae found along the Indian coast.
• Amphipods act as indicators for climate change impact and coastal ecosystem health.
