摘要:

记述了寄生于黑鲷(Sparus macrocephalus(Basilewsdy))鳃上的海盘虫属两新种。华南海盘虫,新种Haliotrema austrosinense sp.nov与螺旋海盘虫(Haliotrema spirale Yamaguti,1968)相比,交接器形状相似但量度有明显的差异,且已知种的交接管具有3条几丁质丝;中央大钩与联结片的形态与已知种相异,表现在:新种的2对中央大钩形态各异,背中央大钩基部不加厚,内外突发达,腹中央大钩基部加厚,内外突粗壮发达,背联结片长片状,中间有两个似驼峰状的突起,两端略尖,腹联结片弧形,中间细,两端膨大,而已知种的2对中央大钩形态相似,钩基部两边加厚,内突非常粗壮发达,背联结片较平直,腹联结片呈“V”形。大弯管海盘虫,新种Haliotrema grossecurvitubus sp.nov与Haliotrema kurodai Ogawa & Egusa,1978相比,交接管形状相似,但交接管的据弯度较已知种长近1倍,且新种交接器具有一台状的基座;2对中央大钩形态各异。
