Caridina cantonensis Yu, 1938 View in CoL
Caridina cantonensis Yu, 1938: 290 View in CoL , figures 7, 8 [type locality: Guangdong, China]– Cai & Ng, 1999:1610, figures 4, 5, 6C–E, 6H–N– Liang, 2004: 179, figure 87.
Caridina yulinica Cai & Ng, 1999:1620 View in CoL , figures 9–11 [type locality: Niuwo cave near Kuiyang Town, Yulin, Guangxi, China].
Caridina mutata Cai & Ng, 1999:1624 , figures 12, 13 [type locality: Fangcheng Town , Fangcheng County, Guangxi, China].
Material examined: 5 males ( FSTC, 20010701 to 05): cl 3.5–4.9 mm ; 2 females ( FSTC, 20010706 to 7), cl 3.8–4.8 mm, near Mashi town , Jianghua County, Hunan province . 9 July 2001; 15 males ( FSTC, 20040701 to 15): cl 3.0– 5.1 mm ; 10 females ( FSTC, 2004 0716 to 25), cl 3.3–5.2 mm, near Suocheng town , Lanshan County, Hunan province . 13 July 2004.
Diagnosis: Rostrum short, extending to end of second segment of antennular peduncle, dorsal border bearing 9–17 teeth, with 5–7 teeth situated behind the posterior orbital margin, 2–6 ventral teeth. Endopod of the first male pleopod rectangular, wide distally, inner margin concave, with a few thin marginal spiniform setae, outer margin straight; appendix interna well developed, arising from middle of endopod, just reaching end of endopod. Appendix masculina glabrous, reaching about 1/2 of endopod, inner margin and tip bearing numerous long spines; appendix interna reaching about half of appendix masculina. Eggs 0.63–0.72 x 0.99–1.09mm in diameter.
Remarks: This species is an easily recognized atyid shrimp of Hunan Province distinguished by its unusually longer stylocerite, which reaching beyond end of basal segment of antennular peduncle. The taxonomy of this species was reviewed by Cai (1999). Liang (2004) subsequently synonymized Caridina yulinica and Caridina mutata with Caridina cantonensis . The present materials agree well with the previous description ( Yu, 1938; Cai, 1999; Liang, 2004). It is a common atyid shrimp in southern China. This is the first record of the species from Hunan Province. It has been found in mountain streams, and usually collected together with Marcobrachium nipponense (De Haan, 1849). With the striking reddishbrown transverse bands on the body, Caridina cantonensis has been cultivated in the aquarium in Guangdong and Shanghai in recent years.
Distribution: Guangdong, Guangxi, Hunan, and Hongkong; Vietnam.
