A new species of troglobitic freshwater prawn of the genus Macrobrachium Bate, 1868 (Crustacea: Decapoda: Palaemonidae) from Phong Nha-Ke Bang national park, Quang Binh province

Researchers have discovered a new species of troglobiotic freshwater prawn, Macrobrachium phongnhaense, in the caves of Phong Nha-Ke Bang National Park, Vietnam. This species is characterized by its transparent body, highly degenerated eyes, smooth and slender second pereiopods, elongated telson, and unarmed preanal region. The discovery was made through morphological comparisons with allied troglobiotic congeners, revealing unique traits that distinguish it from other known species, such as M. lingyunense and M. elegantum. This new species inhabits lightless cave streams and standing waters, typically found in substrates like silt or sandy mud. The findings contribute to the understanding of biodiversity within UNESCO-listed Phong Nha-Ke Bang National Park, highlighting its unique subterranean ecosystems.
