Abstract:
The present paper deals with two new species and a new subspecies of atyid shrimps from China. The type specimens are preserved in Shanghai Fisheries University. Neocaridina heteropoda sp.nov. The present new species is closely allied to Neocaridina denticulata De Haan.1849, but differs from the later in the following features: The 3rd and 4th legs are sexually dimorphous. The 3rd leg of the male is longerthan that of the female. The propodus of the male is curved and bowshaped, and dilated atthe distal part, the posterior border is covered with many spinules. The dactylus is dilated too, the spinules are hook-shaped at the distal part. Holotype: Baisha, Jiande, Zhejiang. Neocaridina euspinosa homospina subsp.nov. The present new subspecies is closely allied to Neocaridina euspinosa euspinosa Cai, 1996, but differs from the latter in the following features: The dorsal teeth of the rostrum is less in number, and the ventral teeth is more. The 3rd leg of male is longer than that of the female. The spines of the dactylus of the 3rd male leg are less in number, and those of the 5th leg are more. Holotype: Shaodong, Hunan. Paracaridina zijinica sp.nov. Rostrum is short and narrow, rostral fornula: 0———1+4———11/0———1. The end of the telson bears a dorsal spinule in the middle. The stylocerite reaches beyond the end of the basal segment of the antennular peduncle. The shape and structure of the lst male pleopod and appendix masculina are characteristic. They are different from all species in this genus. Holotype: Zijin, Guangdong.
