Species Composition and Distributional Characteristics of Freshwater Decapod Crustaceans (Crustacea: Decapoda) and Molluscs (Mollusca) in Xuan Son National Park, Phu Tho Province
Main Article Content
Abstract
Abstract: The present study has recorded 32 species, 22 genera and 14 families of freshwater decapod crustaceans and molluscs in Xuan Son National Park. Eight species were new additions to the list of species known from this National Park, one of them was recorded from Vietnam for the first time, Bithynia funiculata Walker, 1927. Among 14 families, four were decapod crustaceans, and 10 were molluscs. Decapoda was found with seven species (accounted for 21.9% of the total species number), and four genera (accounted for 18% of the total genus number found in the area), while Mollusca was found with 25 species (78.1%) and 18 genera (82%). There was no significant difference in the number of species among different habitats.
