On the genus Exopalaemon (Decapoda, Caridea, Palaemonidae) in Guangdong Province, southern China.

Four species of white prawns of the genus Exopalaemon are recorded from Guangdong Province, southern China, including one new species, Exopalaemon guangdongensis, and a new record, E. modestus (Heller, 1862). E. guangdongensis new species is distinguished from its closely similar congeners by its rostral formula, the form of the four posterior abdominal somites, the ratios of the segments of the second pereiopod, and the size of its eggs. A key to the known Exopalaemon species from China is provided. [ABSTRACT FROM AUTHOR]
