| 摘要: |
| 研究了2010年4月到5月和2012年6月二次采集自刚果盆地的水样,共发现棘管轮属Mytilina Bory de St.Vincent 1826的8个种,其中2个种 M.crassipes (Lucks,1912) 和 M.trigona (Gosse,1851)是非洲新纪录种; M.macrocera (Jennings,1894)和 M.bisulcata (Lucks,1912)是刚果盆地多个样点的常见种;M.ventralis (Ehrenberg,1830)和M.trigona,在刚果盆地个别样点比较多见;M.michelangllii Reid & Turner,1988, M.crassipes和M. brevispina (Ehrenberg,1830)在此次刚果盆地的调查中非常罕见;描述了一种棘管轮,其形态奇特,可能是新种. |

| Abstract: |
| Over 110 samples of Rotifera collected during April-May 2010 and June 2012 in freshwater habitats from the Congo Basin,DRC,were examined.As part of the survey,we here report on 8 taxa of Mytilina found.Two of these,M.crassipes (Lucks,1912) and M.trigona (Gosse,1851) are new records for Africa. M.macrocera (Jennings,1894) and M.bisulcata (Lucks,1912) are relatively frequently encountered.M.ventralis (Gosse,1886) and M.trigona (Gosse,1851) occurred in high numbers at one or two localities,whereas M.brevispina (Ehrenberg,1830), M.crassipes and M.michelangllii (Reid & Turner,1988) are very rare.A brief report on a possibly new species of Mytilina,exhibiting peculiar and unique features,is presented. |
