STUDY ON CARIDINA (DECAPODA, CARIDEA) FROM YUNNAN, CHINA

(Shanghai fisheries College)
ABSTRACT
In the present paper nine species of Caridina collected by the authors from Yunnan Province in 1983 are reported. Of these species four are described as new. The type specimens are kept in the Shanghai Fisheries College. The diagnosis of the new species is given below.
Caridina dianchiensis sp. nov. Rostrum extends to the extremity of the third segment of the antennular pedun
cle. The upper margin is provided with 14—18 teeth, 7—10 of which are placed on carapace behind the orbit. The distal 1/3—1/2 of the upper margin is devoid of teeth.
Carpus of the first leg is 1.6—2.0 times as long as wide. Carpus of the second leg is 5.0—5.3 times as long as wide. The third legs of the male are longer than those of the female, its propodus is 3.5—3.7 times as long as dactylus, which bcears 34—37 spinu-les.
The endopod of the first male pleopod is suboval in shape, and the distal 1/3 of the inner border is slightly concave. The proximal half of the outer 'border bears long plumose setae, and the distal half is armed with long spinules. The appendix masculi-na of the second pleopod is rod-shaped, thin but long, and bears few spines.
Comparison The endopod of the first male pleopod of the new species closely resembles that of Caridina serrata Stimpsou, but differs from the latter in the
3 m m$i^r$i&: ^mmmfzRm^mmm 205 following features: (1) rostrum is long, the distal 1/2 of the up ler bor lei is devoid of teeth, the number of teeth situated on carapace behind the orlbita and on ventral border of rostrum is comparatively greater; (2) palm of the first leg is shorter than the dacty-lus and the chela is slender; (3) proximal half of the outer border of the endopod of 1st male pleopod bears many long plumose seta and the distal half is armed with many long spinules; (4) appendix masculina of the 2nd pleopod is long and slender, and the spines are fewer; (5) spines of the exopod of the uropod are fewer*
Type locality: Kunming. Caridina heterodactoyla sp. nov.
Kostrum commonly extends to the extremity of the third segment of antennular pe
duncle. The upper margin is provided with 20—26 teeth, 8—10 of which are placed on
carapace behind the orbit. Carpus of the first leg is 2.0—2.3 times as long as wide. Carpus o" the second leg
is 4.3—5.4 times as long as wide. The third legs of the male are longer ilu'n those of the female, propodus is 3.0—3.6 times as long as dactylus, whicb bears 7 spmuies, the spinules in male are larger than those in female. Pj-opodus of the fifth leg is 3.2 —3.5 times as long as dactylus, which bears 36—42 spinules
The endopod of the firs'; pleopod of male is leaf-shaped, its inner border is slightly concave at middle ; the appendix interna does not reach beyond the extremity of the endopod. The appendix rrjasculina is spade-shaped. The inner or outer border bears many sipines.
Comparison The present new species closely resembles Caridina gregoriana Kemp in the shape of the endopod of the 1st male pleopod and appendix masculina of the 2nd pleopod, but differs from the latter in the following features: (1) teeth on the dorsal and ventral borders of rostrum and orbit are more numerous; (2) carpus of the 1st leg is slender; (3) propodus of the third and forth legs is similar in form and structure irrespective of sex, and the outer uropod has more spinules.
Type locality: Shizong. Caridina longa sp. nov. Rostrum reaches the extremity of antennular peduncle or antennal scale, the proxi
mal part of its upper border bears 10—12 teeth, 6—8 of which are placed on carapace behind the orbit; its ventral border bears 5—8 teeth.
Carpus of first leg is 1.4—1.5 times as long" as wide, and that of the second leg is 3.8 —4.2 times. Propodus of the third is 3.4—-3.8 times as long as dactylus, which bears 30—36 spinules.
The endopod of the 1st pleopod is rectangular and wider proximally. The appendix masculina is very long and bears long spines on the inner and distal part.
Comparison This new species closely resembles Caridina dianchicnsis, sp. nov. but differs from the latter in the following features: (1) the teeth of the dorsal border of rostrum and orbit are less in number; (2) carpus of 1st and 2nd legs is shorter; (3) the 3rd pair of legs of the males and females is about the same length; (4) propodus of the, 5th leg is less than 4 times as long as dactylus; (5) the inner border of the endopod of the 1st male pleopod is deeply concave, the spinules of the proximal part are longer, appendix interna slender, reaches the middle of the endopod; (6) appendix masculina is much longer and bears many strong spinules at the inner border and distal

part. Type locality: Jianshui. Caridina yui sp. no v. Rostrum reaches to the extremity of the antennal scale, the proximal part of its up
per border bears 5—13 teeth, 2—7 of which are placed on carapace behind the orbit, the tip is common to bear 1—2 teeth. The ventral border bears 6—12 teeth. The telson bears 9—12 pairs of dorcal spinules.
Carpus of the first leg is 1.9 times as long as wide. Carpus of the second leg is 5 times as long as wide. Third legs of male are longer than those of the female, its pro-podus is very conspicuous, dilated at the distal part, the posterior border is covered with many spinules. The daetylus bears 14—17 spinules in females and 19—23 spinules in males.
Comparison The present new species closely resembles Caridina gregoriana Kemp, but differs from the latter in the following features: (1) the teeth of the ventral border of the rostrum are much more in number, (2) the dorsal spinules of the telson are comparatively numerous; (3) spinules of the daetylus of the 3rd leg are less in number.
Type locality: Qiubei.
