中国浙江少鳞鳜属一新种(鲈形目,鮨科,鳜亚科)
|
摘要
根据采自浙江淳安的19尾标本鉴定描记了少鳞鳜属1新种,刘氏少鳞鳜Coreoperca liui sp.nov.。在一些形态性状上与属内已知种存在明显差异:以侧线鳞50以上(vs.50以下)和体高/体长(28.3%~31.9%vs.43.5%)区别于日本少鳞鳜C.kawamebari;以下鳃盖骨边缘有(vs.无)锯齿和臀鳍条10以上(vs.10以下)区别于朝鲜少鳞鳜C.herzi;以体高/体长(28.3%~31.6%vs.33.5%~39.1%)和眼间距/体长(4.6%~5.6%vs.6.6%~8.5%)区别于中国少鳞鳜C.whiteheadi。新种的分布区与属内其它已知种亦不同。
Coreoperca liui, new species, is here described on the basis of 19 specimens collected from the Qiantang Jiang basin in Zhejiang,South China. It is distinct from C. kawamebari,in having more than( vs. less than) 50 lateral line perforated scales and a less shallow body( depth 28. 3 %- 31. 9 % vs.43. 5 % SL),and from C. herzi,a Korean endemic species, in having a serrated( vs. non-serrated)posteroventral edge of the suboperculum,and more than( vs. few er than) 10 anal-fin branched rays. This new species can be distinguished from C hinese endemic species C. whiteheadi by having a less shallow body( depth 28. 3 %- 31. 6 % vs. 33. 5 %- 39. 1 % SL)and a smaller eye( diameter 4. 6 %- 5. 6 % vs. 6. 6 %- 8. 5 % SL).
