SEM morphological study of the Late Permian clam shrimp Polygrapta chatangensis (Spinicaudata, Crustacea)

State Key Laboratory of Palaeobiology and Stratigraphy, Nanjing Institute of Geology and Palaeontology and Center for Excellence in Life and Paleoenvironment, Chinese Academy of Sciences, East Beijing Road 39, Nanjing 210008, PR China
Crustacea Spinicaudata Clam shrimp Upper Permian Polygrapta taxonomy


A re-examination of the metatype of the type species Polygrapta chatangensis has revealed new characters that were overlooked in the original description and it is determined here that Polygrapta should be maintained as a genus separate from Pseudestheria.
