Species of Caridina nilotica group in China, with description of one new species (Crustacea, Decapoda, Atyidae)

Abstract

Abstract The atyid shrimps of Caridina nilotica species group from China are reviewed. Taxonomic diagnosis and discussions are given to three species so far known from China, viz. Caridina gracilipes De Man, 1892, Caridina macrophora Kemp, 1918 and Caridina elongapoda Liang & Yan, 1977. Detailed morphological description and illustrations are provided for a new species. Caridina sheni sp. nov. is morphologically similar to C. gracilipes but could be distinguished by its much longer dactylus of third and fifth pereiopods, and lower number of ventral rostral teeth.
